Summary of U.S. Patent No. 11,048,300

Title: Flexible and rigid touch screen display computing devices

Assignee: Lepton Computing LLC

Inventor(s): Stephen E. Delaporte

Filing Date: January 12, 2021

Issue Date: June 29, 2021

Abstract:

This patent describes a reconfigurable computing device that can switch between a compact, phone-like form and an expanded, tablet-like form. The device utilizes a touch screen display made of multiple segments that can be folded and unfolded. In its compact state, it resembles a standard smartphone with a single screen, a speaker, and a microphone. When expanded, it offers a larger, continuous display similar to a tablet, and in some configurations, it can function like a small laptop. The invention also includes a graphical user interface that adapts the displayed content as the device is transformed between its different states. A key feature is a central module containing the processing and memory components, which remains functional in both the compact and expanded forms.

Plain-Language Overview of Independent Claims:

This patent has a number of independent claims, which define the core of the invention. Here is a simplified explanation of their key aspects:

• Claim 1: This claim describes a computing device with a multi-segment touch screen that can be folded into different configurations. It specifies that in its compact form, the device has a single active display on the front and a protective back. In its expanded form, the multiple screen segments work together as a larger, single display. The claim also mentions sensors that detect the device's configuration (folded or unfolded) and a processor that adjusts the display content accordingly. A central module houses the main electronic components.

• Claim 9: This claim focuses on the method of transitioning the display content. It details how the device's software recognizes the change from a compact to an expanded state (and vice versa) and automatically rescales the user interface to fit the new screen size. This allows for a seamless user experience when switching between the two modes.

• Claim 14: This claim describes the physical mechanism for connecting and aligning the different screen segments. It introduces the concept of a flexible circuit that connects the segments and allows them to fold. It also mentions the use of an "alignment locking mechanism" to ensure the segments form a flat and stable surface when in the expanded state. This mechanism is crucial for the usability of the large, combined screen.

• Claim 19: This claim details another variation of the folding mechanism. It describes a system where the screen segments are supported by a frame with hinges, allowing for a more rigid and stable structure. This embodiment also includes sensors and magnets to help secure the device in its different folded positions. It further specifies the placement of a speaker and microphone to be functional in both the compact and expanded states.

NPE / troll-pattern signals

1. Shell-entity transfer — Present. The original assignee, Lepton Computing LLC, does not appear to have commercial products embodying the claims, and the assignment record indicates the inventor assigned their rights to this LLC. The nature of "Lepton Computing LLC" without public product lines or extensive operational details is consistent with a licensing-only entity. The correspondent's address is a P.O. Box in Dallas, TX, which is common for such entities.
2. Known asserter in the chain — Unclear. Lepton Computing LLC is not explicitly listed on widely known public NPE lists such as those maintained by RPX or Unified Patents, based on available search results. However, the company's profile suggests patent monetization as its primary activity.
3. Repeat correspondent across the chain — Unclear. Jeffrey B. Sladkus of Jeff Sladkus Consulting, P.C., is the correspondent on the initial assignment from the inventor to Lepton Computing LLC (Reel 056461/0002). While this is the only assignment in this patent's chain, without broader data on other patents handled by this correspondent, it is unclear if this represents a "repeat correspondent across the chain" in the context of a family of NPEs.
4. Cascading transfers — Not present. There is only one recorded assignment in the chain for this patent, from the inventor to the assignee, and no multiple consecutive transfers within a short period.
5. Pre-litigation transfer — Not present. As per the litigation summary, no litigation involving US11048300 has been identified.
6. Bankruptcy fire-sale — Not present. There is no indication in the patent record or public information that the assignment originated from a bankruptcy proceeding.
7. Privateering — Unclear. There is no public information to suggest that Lepton Computing LLC is asserting this patent on behalf of an operating company competitor.
8. Defensive aggregator (anti-NPE) — Not present. The current assignee, Lepton Computing LLC, is not a known defensive aggregator.

Verdict

NPE — moderate confidence. While there is only one recorded assignment, the nature of the assignee, Lepton Computing LLC, appears to be consistent with a shell entity, given the lack of public product information and its designation as an "Original Assignee" shortly before patent grant. The correspondent's mailing address (P.O. Box) also aligns with patterns seen in NPE operations. This suggests the patent was acquired by Lepton Computing LLC for potential licensing or assertion purposes.

Obviousness Analysis of U.S. Patent 11,048,300 under 35 U.S.C. § 103

This analysis assesses the obviousness of the claims of U.S. Patent 11,048,300, titled "Flexible and rigid touch screen display computing devices," under 35 U.S.C. § 103. The analysis relies on the "Prior art keywords" provided within the patent document (OLED display, flexible touch, structural support, support segment, sensitive OLED) and assumes these represent technologies and concepts generally known to a person having ordinary skill in the art (PHOSITA) at the patent's priority date of August 10, 2010.

Person Having Ordinary Skill in the Art (PHOSITA)

A PHOSITA in the context of this patent, at the priority date of August 10, 2010, would be an engineer or designer with expertise in mobile computing device hardware and software, display technologies, flexible electronics, and user interface development. This individual would be knowledgeable about various display types (e.g., LCD, OLED), touch input mechanisms (e.g., capacitive, resistive), flexible circuit design, mechanical engineering principles for portable devices (e.g., hinges, latches, structural reinforcement), and software development for adapting user interfaces to different screen configurations.

Motivation to Combine Prior Art Elements

At the priority date, the mobile computing market was rapidly evolving, with a clear demand for devices that offered larger display areas without sacrificing portability. The patent itself acknowledges this market need, stating, "One of the great difficulties in using a small-scale touch screen device, however, is in the fact that it can often be cumbersome to physically interact with." and "There is therefore a need for touch screen displays having increased size without sacrificing the convenience of a small device." Furthermore, the patent notes that "variations on flexible displays and the implementation of multiple screen displays have been proposed to enable the transformation of a display from a compact state to an expanded state."

This background establishes a strong motivation for a PHOSITA to combine existing technologies to address the problem of limited screen size in portable devices. The objective would be to create a reconfigurable device that could provide a compact form factor for handheld use and an expanded form factor for enhanced viewing and interaction, analogous to a tablet or laptop. The individual concepts represented by the prior art keywords—"OLED display," "flexible touch," "structural support," "support segment," and "sensitive OLED"—would be recognized as relevant tools and technologies to achieve this goal.

Obviousness Analysis by Independent Claim

Given the aforementioned motivation, the independent claims of U.S. Patent 11,048,300 would likely be considered obvious combinations of known prior art elements.

Claim 1: Reconfigurable Computing Device

Claim 1 describes a computing device comprising a reconfigurable touch screen display made up of a plurality of segments. The device transitions between a compact state (single active display, protective back) and an expanded state (multiple segments forming a single larger display). It includes sensors to indicate the configuration state, a processor to adjust display content, and a module with core electronics within at least one segment, usable in both states.

A PHOSITA, motivated to create a larger, portable display, would find it obvious to combine the following known concepts:

• Multiple display segments: The concept of using multiple display segments to form a larger display was known, as indicated by the patent's own acknowledgment of "implementation of multiple screen displays" in the prior art.
• Flexible touch/sensitive OLED/OLED display: These keywords suggest that flexible, touch-sensitive OLED displays were known. A PHOSITA would naturally consider using such displays for segments in a reconfigurable device due to their thinness and potential for flexibility, which the patent highlights as advantageous.
• Structural support/support segment: To make a multi-segment display robust and functional, particularly one that reconfigures, providing "structural support" to each "segment" would be a fundamental engineering consideration. The patent itself highlights the need for a "reconfigurable structure and an alignment locking mechanism" as advantageous for flexible touch screens.
• Compact and expanded states: The problem driving the invention was the limitation of small screens. Therefore, designing a device to have both a smaller, portable state and a larger, expanded state would be the direct solution to that problem, as acknowledged in the background of the invention.
• Sensors and processor for content adjustment: Once a reconfigurable display is envisioned, it would be an obvious design choice to incorporate sensors to detect its physical configuration. Furthermore, it would be a routine software engineering task to have a processor, upon detecting a change in configuration, rescale or adapt the displayed content for the new screen size and aspect ratio, similar to how operating systems adapt to external monitors or resolution changes.
• Core electronics module in one segment: For modularity, ease of assembly, and to minimize interference during folding, a PHOSITA would logically house the primary processing, memory, and communication components in a dedicated segment. The patent describes placing "substantially all processing, peripheral ports, communications circuitry, battery and additional core electronics" in one segment to allow for smooth folding and access to ports.

Claim 9: Method for Transitioning Display Content

Claim 9 describes a method for operating such a computing device, including detecting the transition between compact and expanded states via sensors and rescaling content based on the detected state.

This method would be an obvious application of known principles in user interface (UI) design and sensor integration, building upon the structural elements discussed in Claim 1:

• Detecting transition via sensors: As noted for Claim 1, integrating sensors to detect the physical state of a reconfigurable device is a predictable engineering step. The patent describes "segment sensors" and "folded state sensors" performing this function.
• Rescaling content for new screen size: Once the change in screen dimensions is detected, adapting the display's content to fit the new layout is a routine and well-understood UI development task. Software was already capable of adjusting layouts and content for various screen sizes and orientations. A PHOSITA would be motivated to provide a seamless visual experience for the user transitioning between display states.

Claim 14: Flexible Circuit and Alignment Locking Mechanism

Claim 14 focuses on the physical mechanisms: a flexible circuit coupling segments and an alignment locking mechanism.

These elements address predictable engineering challenges in creating a multi-segment, reconfigurable display:

• Flexible circuit coupling segments: Given "flexible touch" and "OLED display" (which can be thin and flexible), using a "flexible circuit" to electrically connect moving display "segments" is a direct and obvious solution to maintain electrical continuity during reconfiguration. The patent illustrates such flexible circuits and sliding connectors between segments.
• Alignment locking mechanism: For multiple segments to form a seemingly continuous and flat touch screen in an expanded state, precise alignment and stability are critical for both visual appearance and touch functionality. A PHOSITA would naturally employ an "alignment locking mechanism" to ensure the segments are held together rigidly and accurately. The patent describes various mechanisms including latches, magnets, and alignment plates to provide "structural support between each segment."

Claim 19: Frame with Hinges, Sensors, Magnets, Speaker/Mic

Claim 19 details a device with a frame including hinges supporting segments, sensors, magnets for securing positions, and functional speakers and microphones in both states.

This claim represents a known combination of mechanical and electronic features:

• Frame with hinges supporting segments: Using frames and hinges to connect and support components of foldable electronic devices (e.g., laptops, flip phones) was a long-standing practice. Applying this to display "segments" to enable folding and unfolding, while providing "structural support," would be an obvious mechanical design choice for a PHOSITA.
• Sensors to indicate configuration state: As discussed for Claims 1 and 9, integrating sensors to detect the device's physical state is a logical inclusion for interactive reconfigurable devices.
• Magnets to secure device in folded positions: Magnets were commonly used in portable electronics (e.g., tablet covers, convertible laptops) to secure parts in desired configurations, offering a simple and effective locking mechanism without bulky hardware. The patent mentions magnets for "connecting and aligning each of the segments as they are folded flat against each other."
• Speaker and microphone functional in both states: Integrating audio components (speaker, microphone) into mobile phones and computing devices was standard. Designing their placement such that they remain functional across different form factors (compact phone state, expanded tablet/laptop state) would be a routine design optimization for a PHOSITA to ensure continuous functionality. The patent describes the integration of a speaker and microphone in the compact phone state.

In conclusion, a PHOSITA in 2010, motivated by the clear market demand for larger, yet portable, display solutions, would have found it obvious to combine the known concepts and technologies represented by the "prior art keywords" (OLED display, flexible touch, structural support, support segment, sensitive OLED) to arrive at the inventions claimed in U.S. Patent 11,048,300. The individual elements perform their known functions to achieve predictable results in addressing a known problem, with additional features representing routine design choices and optimizations.

US Patent 11,048,300 — Term, Continuity, and Family Analysis

Important data-source note: I was unable to retrieve live USPTO Patent Center/Public PAIR records in my searches (the searches returned only general PTA/PTE guidance, not case-specific data for this patent). The analysis below therefore relies on the authoritative full patent text (Google Patents record for US11048300B2, fetched 2026-08-26) plus the patent's own cross-reference section. Items requiring USPTO verification are explicitly flagged.

1. Priority chain and application type (as stated on the face of the patent)

The "Cross Reference to Related Applications" section of US11048300B2 expressly recites:

The patent states it "is a continuation and claims the benefit, under 35 U.S.C. § 120, of U.S. patent application Ser. No. 16/237,484" — making US11048300B2 itself a continuation, not a first-filed application.

2. Continuation applications

• Confirmed: 17/147,340 (→ US11048300B2) is a continuation of 16/237,484, which in turn is a continuation of 13/206,333. This is stated on the face of the patent.
• The related PCT application WO2011019864A2 (filed 2010-08-10, published 2011-02-17, inventor S. E. Delaporte) corresponds to the priority chain and is listed among the cited references.
• The cited-reference list also includes several same-inventor publications (e.g., US20130088825A1, US20140226315A1, US20150116937A1, US20120113596A1, US20090096954A1). I could not confirm from available sources whether these are formal family members (continuations sharing the chain) or separate applications merely cited as prior art. Do not assume they share the 13/206,333 priority chain without USPTO verification.

3. Divisional applications

• None identified. No divisional application is referenced anywhere in the patent text, and my searches returned no divisional filings in this chain.

4. Patent term adjustment (PTA)

• No PTA figure is printed in the available record, and my searches did not return a case-specific PTA value for US11048300B2.
• Proxy evidence suggests zero or minimal PTA: the application 17/147,340 was filed 2021-01-12 and granted 2021-06-29 — roughly 5.5 months of prosecution. PTA compensates for USPTO-caused delay (A/B/C delays under 35 U.S.C. § 154(b)); an expedited, uninterrupted continuation prosecution of this length ordinarily accrues little or no PTA.
• Verification required: the authoritative PTA figure is printed on the patent front page ("* Term Extension" / "PTA" field) and in USPTO Patent Center under the "Patent Term Adjustment" tab. I could not access that live data. The rule of thumb: if the true expiration is later than 2031-08-09, PTA is the likely cause.

5. Patent term extension (PTE)

• Not applicable / none recorded. PTE under 35 U.S.C. § 156 is limited to patents covering FDA-regulated products (drugs, medical devices, etc.). US11048300B2 claims a reconfigurable touch-screen computing device — not a regulatory-approved product — so no PTE applies.

6. Projected expiration date

• Anticipated expiration (per the Google Patents record): 2031-08-09.
• How this is derived: 20 years from the earliest non-provisional filing date in the chain — 13/206,333 filed 2011-08-09 (the provisional 61/372,391, filed 2010-08-10, does not start the term). 2011-08-09 + 20 years = 2031-08-09.
• Caveats:
  • This 2031-08-09 figure appears to be the unadjusted 20-year term. If USPTO Patent Center shows any PTA days, the true expiration shifts later by that amount.
  • No terminal disclaimer is evident in the record I have; if one exists (e.g., tied to a parent patent for obviousness-type double patenting), the expiration could be constrained to an earlier date and, post-In re Cellect, PTA would not extend beyond a terminal disclaimer date. Verify via USPTO Patent Center.
  • Status is Active; expiration also assumes maintenance fees are kept current (not part of the term calculation, but a lapse would end enforceability early).

7. Family summary

• Darts-ip family identifier referenced on the patent record: 44509692 (listed in the "Family has litigation" field).
• Core family (confirmed): 61/372,391 → 13/206,333 → 16/237,484 → 17/147,340 (US11048300B2), plus PCT WO2011019864A2.
• Contradiction to flag: the earlier-generated litigation summary in this analysis (dated 2026-04-26) stated no litigation was identified, but the authoritative Google Patents record fetched 2026-08-26 includes a "Family has litigation" indicator pointing to a Texas Eastern District Court case 2:26-cv-00338 (per Unified Patents litigation data). Per the operating rule that the fetched patent text controls, that case should be treated as existing; its parties and status were not available in my sources. This does not affect the term analysis.

Bottom line

• Expiration (base term): 2031-08-09 (20 years from 2011-08-09).
• PTA: not confirmed; likely zero/minimal given the fast prosecution — verify in USPTO Patent Center.
• PTE: none.
• Continuations: 17/147,340 → 16/237,484 → 13/206,333 → provisional 61/372,391.
• Divisionals: none identified.
• Authoritative verification: USPTO Patent Center (search Patent No. 11048300 or Application No. 17/147,340) for the printed PTA value, any terminal disclaimer, and maintenance-fee status.

1. Derivative Set A — Claim 1 (Reconfigurable Segmented Display Device)

A1. CNT/Graphene Substrate with EGaIn Liquid-Metal Interconnects

Axis: Material & Component Substitution

Enabling Description. Substitute the conventional polyimide/copper stack with a transparent carbon-nanotube (CNT) network substrate (sheet resistance <100 Ω/sq at 85% transmittance) or 12.5 µm Kapton HN coated with a 20 nm Al₂O₃ barrier deposited by atomic layer deposition (ALD). Replace copper traces with eutectic gallium-indium (EGaIn, 75.5 wt% Ga / 24.5 wt% In, m.p. 15.7 °C) injected into 50 µm × 50 µm polydimethylsiloxane (PDMS) microchannels; EGaIn self-heals after fold-fatigue microcracking. Display stack: inverted top-emitting OLED on the flexible substrate with thin-film encapsulation (Al₂O₃/ZrO₂ nanolaminate, 2 dyads). Touch electrode: silver-nanowire (AgNW) mesh or PEDOT:PSS replacing ITO. Segment-to-segment hinge: CNT-fiber-reinforced silicone flexure rated to 200,000 cycles at 2 mm bend radius. Alignment latch: NiTi shape-memory alloy pin (55Ni-45Ti) actuated at 60 °C. This preserves the Claim 1 architecture (segments, compact/expanded states, state sensors, processor, core module) while substituting every material layer.

A2. MEMS Micro-Tile Array at Nanoscale Pitch

Axis: Operational Parameter Expansion

Enabling Description. Scale the segment count from 4–8 macro-segments to 1,600 micro-tiles of 2.5 mm × 2.5 mm, forming a 100 mm × 100 mm array (400 × 400 mm equivalent at 16:9 expansion). Each tile is 0.35 mm thick, contains a low-temperature polycrystalline silicon (LTPS) TFT backplane with a self-contained gate driver, and is separated from neighbors by a 50 µm laser-cut liquid-crystal-polymer (LCP) flex bridge. Registration between tiles is achieved by MEMS electrostatic comb drives providing ±5 µm positioning; the tile carrier is a CTE-matched alumina substrate to prevent thermal buckling. Fold-state sensors are per-tile break-beam IR pairs. The processor treats the array as one logical display in expanded state and a single active tile in compact state. Extreme-scale operation: 240 Hz refresh per tile with 1 ms inter-tile synchronization skew budget.

A3. Cross-Domain — Deployable Satellite Reflectarray Terminal

Axis: Cross-Domain Application (Aerospace)

Enabling Description. Apply the Claim 1 reconfiguration architecture to a spacecraft communications terminal. Four rigid CFRP segments carry a foldable reflectarray of vapor-deposited aluminum patches on 30 µm Kapton, accordion-deployed from a 1U stowed volume to a 4× aperture. Deployment is spring-damper controlled with CFRP rigidizing struts; magnetoresistive angle sensors on each hinge confirm state, analogous to the patent's fold-state sensors. A nichrome heater layer maintains -60 °C to +125 °C survivability. The core-electronics module is the satellite's software-defined radio (SDR) transponder, usable in both stowed (omni beacon) and deployed (high-gain) states. Pointing accuracy target: 0.5°. State-transition logic is gated by sun-sensor confirmation and deployment timer.

A4. Cross-Domain — AgTech Foldable Multispectral Crop-Sensing Panel

Axis: Cross-Domain Application (AgTech)

Enabling Description. Mount a four-segment foldable multispectral imaging panel on a UAV or field robot. Each segment carries a 5 MP CMOS sensor with 10 nm FWHM bandpass filters at 475, 560, 668, and 840 nm; expanded state yields a 4× composite imaging aperture for NDVI/NDRE computation. Add UV-LED (365 nm) excitation for NPK fluorescence sensing. Segment sensors (magnetic reed switches) trigger the processor to switch from compact "scout" mode (single-band NDVI) to expanded "survey" mode (4-band, 12 MP mosaic). A LoRaWAN uplink transmits geotagged vegetation indices; the core module (STM32MP1 + cellular modem) operates in both states.

A5. Cross-Domain — Medical Wearable Foldable Vitals Display

Axis: Cross-Domain Application (Medical)

Enabling Description. Apply the Claim 1 architecture to a body-worn patient monitor. Four OLED segments (0.8 mm total thickness) are encapsulated in autoclavable medical-grade thermoplastic polyurethane (TPU) and fold from a 45 mm compact state to a 180 mm expanded state. ECG dry electrodes and a reflectance SpO₂ sensor are embedded in the hinge zones. Fold-state detection (capacitive proximity pairs) drives telemetry bandwidth scaling: compact state streams 1-lead ECG at 250 Hz; expanded state streams 12-lead at 1 kHz plus plethysmograph. The core module (nRF5340 + analog front end) is shared across states; alarm annunciation uses a piezoelectric transducer embedded in the protective back panel.

A6. Emerging Tech — On-Device AI Content-Scheduling Across States

Axis: Integration with Emerging Technology (AI-driven optimization)

Enabling Description. Augment the processor's content-adjustment function with a quantized on-device ML classifier (TensorFlow Lite, MobileNetV3 at INT8) that runs on fold-state change and classifies usage context into typing, video, reading, or telephony. Based on classification, the GPU/compositor pre-allocates framebuffer planes, touch-sampling rate, and refresh rate for the target state. A 30-day sliding log of state-transition sequences trains an LSTM (on-device, federated) that predicts the next transition with ≥90% accuracy, enabling pre-rendering of both candidate layouts before the mechanical fold completes. This preserves the Claim 1 sensor→processor→display loop while making the content transition predictive rather than reactive.

A7. Emerging Tech — IoT Segment Health-Monitoring Mesh

Axis: Integration with Emerging Technology (IoT sensors)

Enabling Description. Instrument each display segment with an nRF52840 BLE/Thread SoC reporting: hinge torque (350 Ω foil strain gauge on the neutral axis), segment temperature/humidity (SHT40), fold-cycle count (magnetic angle encoder), and OLED burn-in metrics (per-pixel luminance drift estimate). Segments form a Thread mesh (OpenThread) with the core module as the Thread leader; telemetry publishes to an MQTT broker at 1 Hz in expanded state and 0.1 Hz in compact state. Over-the-air (OTA) firmware updates propagate via the mesh. This extends Claim 1's sensor set from configuration-only to continuous structural-health monitoring.

A8. Emerging Tech — Blockchain-Verified Configuration-State Ledger

Axis: Integration with Emerging Technology (blockchain verification)

Enabling Description. Each state transition (compact↔expanded) generates a verifiable credential signed by the device's discrete TPM (ECDSA P-256) containing: transition type, timestamp, segment-sensor bitmap, fold-cycle counter, and firmware version. Credentials are submitted to a Hyperledger Fabric channel with an endorsement policy requiring 2-of-3 device attestors (TPM, secure element, and a segment sensor hub). The ledger enables tamper-evident warranty enforcement based on true fold-cycle count, anti-counterfeit tracking of display modules, and secondary-market verification of device condition. The blockchain layer is orthogonal to the Claim 1 hardware and runs on the core module.

A9. Inverse — Low-Power "Limp Mode" Single-Segment Operation

Axis: The "Inverse" or Failure Mode

Enabling Description. Design a fail-safe variant where, upon confirmed segment-sensor failure (2-of-3 voting across redundant sensor types), the device drops to a low-power single-segment mode: 320×240 QVGA at 0.5% backlight duty cycle (1 kHz PWM, 0.1 nit minimum), display controller clock-gated, and all non-essential segments powered down with MOSFET load switches. Touch remains active in a "blind-dial" emergency path where the RF module bypasses the display controller entirely. Recovery to full expanded state requires a manual membrane-switch override followed by a calibration sequence. This inverse variant guarantees graceful degradation and preserves emergency telephony when the reconfigurable display is damaged.

2. Derivative Set B — Claim 9 (Content State-Transition Method)

B1. Component Substitution — Heterogeneous Redundant Sensing Modalities

Axis: Material & Component Substitution

Enabling Description. Substitute the patent's segment/face sensors with a heterogeneous redundant bank feeding a single state machine: (i) Hall-effect sensors (0.1° resolution) with diametrically magnetized disc magnets on each hinge axis; (ii) IR optical break-beam pairs (940 nm LED + phototransistor) across each fold gap; (iii) 40 kHz ultrasonic time-of-flight pairs measuring fold separation; and (iv) force-sensing resistors (FSR) on tangent faces for compact-state confirmation. The state machine (implemented on a sensor hub MCU) performs sensor-fusion voting: expanded state requires Hall + IR agreement; compact state requires FSR + ultrasonic agreement. Content rescale is triggered only on majority consensus, reducing false transitions from single-sensor noise.

B2. Operational Parameter Expansion — Sub-Millisecond State Handoff

Axis: Operational Parameter Expansion

Enabling Description. Push the Claim 9 method to the extreme of latency: a dedicated sensor hub (STM32L4, 1 kHz edge-triggered sampling) detects fold initiation within 1 ms; the display controller commits the target-state framebuffer within one frame at a 240 Hz panel (4.17 ms); GPU-accelerated bilinear/Catmull-Rom rescaling completes within 3 frames (12.5 ms total). Content continuity is preserved by double-buffered pre-rendering of both states during the mechanical fold (which takes 200–500 ms). This defines the method's performance envelope at the boundary of human perception and establishes that sub-frame transition is achievable with commodity silicon.

B3. Cross-Domain — Automotive Cockpit Display Reconfiguration

Axis: Cross-Domain Application (Automotive)

Enabling Description. Apply the Claim 9 method to a center-stack instrument cluster. The display reconfigures between a compact "driving" state (speed, gear, warning cluster; ISO 15005-compliant minimal glance time) and an expanded "parked" state (full navigation, media, camera views). State gating is driven by CAN bus signals: vehicle speed >5 km/h forces compact state; speed = 0 plus park gear enables expanded state. The method's sensor-triggered rescale is extended with a safety interlock layer: any rescale during motion is clamped to a 200 ms fade to avoid driver distraction. Fail-safe: on sensor disagreement, the cluster defaults to the compact state.

B4. Cross-Domain — Videowall / Digital Signage Aspect Reconfiguration

Axis: Cross-Domain Application (Digital Signage)

Enabling Description. Apply the state-transition method to a videowall controller driving four tiles that physically re-rack between portrait, landscape, and 2×2 configurations. Content scheduling uses SMIL (W3C Synchronized Multimedia Integration Language) as the open control standard; on a rack-state change detected by the tile sensor bus, the controller rescales the active SMIL region to the new canvas and re-times media playlists. The method generalizes Claim 9's single-device rescale to a distributed render farm: each tile renders its region locally, with a master sync clock (PTP/IEEE 1588) holding inter-tile frame alignment to ±1 ms.

B5. Cross-Domain — Avionics Glass-Cockpit Reconfiguration

Axis: Cross-Domain Application (Avionics)

Enabling Description. Apply the Claim 9 method to a DO-160G-qualified glass cockpit where the primary flight display (PFD) reconfigures between compact (attitude, airspeed, altitude, heading) and expanded (route map, weather, traffic) states tied to flight phase (taxi, takeoff, cruise, approach). The method is hardened with triplex redundant sensor voting and a dissimilar back-up: if the fold-state sensor set disagrees, the display latches to the compact PFD format and annunciates a maintenance flag. All rescale operations are pre-rendered and validated against ARINC 661 widget definitions before presentation, so no uncommanded format change can occur.

B6. Emerging Tech — AI Predictive Pre-Fetch and Layout Commit

Axis: Integration with Emerging Technology (AI)

Enabling Description. Extend the Claim 9 method with a predictive pipeline: a partial fold-state trigger (e.g., one of four segment sensors released) feeds an LSTM trained on the user's 1,000-transition history; the model outputs a probability distribution over target states. The GPU pre-renders the two most probable layouts concurrently; when the full trigger confirms the state, the pre-rendered frame commits with zero rescale latency. A confidence threshold of 0.85 gates pre-rendering to conserve power; below threshold, the method falls back to reactive rescale. This makes the transition appear instantaneous without requiring faster hardware.

B7. Emerging Tech — IoT Context-Aware Rescale Parameters

Axis: Integration with Emerging Technology (IoT)

Enabling Description. Parameterize the Claim 9 rescale with IoT context streams: ambient illuminance (photodiode) selects light/dark theme and backlight curve; ultrasonic proximity detects user distance and selects content density (near = detailed, far = high-contrast); calendar/agenda context (via MQTT) pre-selects the target layout (e.g., meeting notes vs. media). The rescale engine consumes these streams at 10 Hz and re-targets the layout continuously during the mechanical fold rather than at a single trigger instant. This makes the method context-adaptive and sensor-driven beyond mere fold state.

B8. Emerging Tech — Blockchain-Verified Per-State Content Licensing

Axis: Integration with Emerging Technology (blockchain)

Enabling Description. Extend the Claim 9 method into a metered-content model: each transition to the expanded state for premium content triggers a Lightning Network micropayment and requests a fresh DRM key from a rights server; the rights server issues a signed viewing receipt (hash of content ID + device attestation + state bitmap) recorded to a public ledger. Key rotation occurs per state so the compact-state preview renders at low resolution while the expanded state unlocks full resolution only after settlement. This integrates the fold-state method with verifiable usage accounting, useful for per-seat media licensing and anti-piracy forensics.

B9. Inverse — Graceful Degradation on Sensor Failure

Axis: The "Inverse" or Failure Mode

Enabling Description. Define the failure-mode method: if one of N fold-state sensors fails, a 2-of-3 temporal voting window (three consecutive 10 ms samples) and cross-modal corroboration (e.g., Hall vs. IR) determine whether the transition is real. On confirmed failure, the method enters a manual-override path: a mechanical push button (membrane switch) cycles states; an on-screen calibration UI re-maps the sensor bitmap. If the display itself is compromised, the method falls back to mirror mode on the single remaining segment. This inverse variant guarantees the method remains operable (not merely safe) under partial sensor loss.

3. Derivative Set C — Claim 14 (Flexible Circuit + Alignment Locking Mechanism)

C1. Material Substitution — LCP Flex, SMA Latch, and Magnetorheological Damper

Axis: Material & Component Substitution

Enabling Description. Substitute the flexible circuit dielectric with liquid-crystal polymer (LCP): Dk 2.9, loss tangent 0.002 at 10 GHz, enabling RF-capable signal routing across segment joints. Replace mechanical alignment pins with two-way shape-memory NiTi pins that latch at 45 °C and release at 10 °C, enabling temperature-triggered lock/unlock without motors. Add a magnetorheological (MR) fluid damper — 30 vol% carbonyl iron in silicone oil — in the hinge cavity whose apparent viscosity changes 50× under a 0.5 T field, providing adjustable damping during fold and rigid locking when the field is applied. All three substitutions preserve the Claim 14 architecture (flex coupling + alignment lock) while changing materials.

C2. Operational Parameter Expansion — Microscale High-Density Sliding Connector

Axis: Operational Parameter Expansion

Enabling Description. Scale the sliding connector to 0.2 mm pitch with 200 contacts per row on gold-plated beryllium-copper (BeCu) springs, ±3 mm sliding travel, contact resistance <50 mΩ, and a 100,000-cycle life rating. Conformal-coat the mated joint with 2 µm parylene-C for environmental sealing. The flex circuit carries differential pairs at 5 Gbps per lane across the sliding joint (validated to PCIe Gen2 eye-mask margins). This establishes the mechanical/electrical envelope for high-density, high-speed signaling across a reconfigurable display seam — far beyond the patent's stated 0.90 mm Molex SlimStack-class connector.

C3. Cross-Domain — Space Deployable Solar Blanket with SMA Release

Axis: Cross-Domain Application (Space)

Enabling Description. Apply the Claim 14 flex-circuit-plus-alignment-lock architecture to a satellite solar array: four perovskite-on-Kapton blanket segments (30 µm substrate, vapor-deposited metal contacts) are stowed against the spacecraft bus and released by NiTi SMA frangible bolts (the alignment-lock analog). The flexible circuit is a rolled-annealed copper busbar mesh laminated in Kapton, carrying per-segment power and IV-curve telemetry. On deployment, wedge locks (spring-loaded, analogous to alignment plates) seat each segment into a coplanar array with ±0.5 mm registration. Telemetry confirms lock engagement before high-power draw is enabled.

C4. Cross-Domain — Retail Rollable e-Paper with Sliding Backing Segments

Axis: Cross-Domain Application (Retail Signage)

Enabling Description. Apply the Claim 14 mechanism to an electrophoretic (E Ink) price-tag display: the display foil (50 µm stainless-steel substrate) is backed by rigid aluminum segments that slide relative to one another via the sliding-connector joint, allowing the tag to roll/unroll between a 65 mm compact spool and a 260 mm expanded banner. The flex circuit bridges segment joints with the sliding connector to maintain EPD drive waveforms during motion. A spring-wedge alignment lock (the Claim 14 lock analog) holds the expanded state flat for optical readability. Updates arrive via NFC or QR from a store hub.

C5. Cross-Domain — EV Battery-Pack Foldable Interconnect

Axis: Cross-Domain Application (Electric Vehicles)

Enabling Description. Apply the Claim 14 flexible-circuit and alignment-lock concepts to a serviceable EV battery pack: module segments (each a 2S2P cell group) are interconnected by 100 µm rolled-annealed copper busbars on a polyimide carrier that fold during pack service access; a sliding connector accommodates thermal-expansion-induced displacement between modules (±2 mm over -40 °C to +60 °C). The alignment lock is a spring-loaded steel wedge that seats each module into the pack tray; the BMS monitors contact resistance across each joint and flags >1 mΩ drift as a service alert. This repurposes the display-seam mechanism as a high-current (200 A) interconnect with lock verification.

C6. Emerging Tech — Machine-Vision Closed-Loop Alignment Verification

Axis: Integration with Emerging Technology (AI/vision)

Enabling Description. Augment the Claim 14 alignment lock with a closed-loop verification and correction stage: a 5 MP camera (mounted in the core module, viewing the segment plane at an oblique angle) detects ArUco fiducials printed on each segment's back panel; cv2.findHomography computes residual misregistration to sub-pixel accuracy (<10 µm). If residual error exceeds 25 µm, piezo actuators under the offending segment apply corrective translation/rotation, and the lock re-engages. The system logs a pass/fail certificate per lock event. This converts the passive alignment plate into an actively verified, self-correcting mechanism.

C7. Emerging Tech — IoT Strain-Gauge Monitoring of Flex-Circuit Fatigue

Axis: Integration with Emerging Technology (IoT)

Enabling Description. Embed 350 Ω foil strain gauges on the neutral axis of each flex-circuit bridge, wired in a Wheatstone bridge to a 24-bit delta-sigma ADC (e.g., ADS1220) on the segment sensor hub. The hub records peak strain per fold event, cumulative strain cycles, and connector contact resistance. A fatigue model (Coffin-Manson law, with exponent fit per material) predicts remaining life; an MQTT alert fires at 85% predicted life. This turns the flex circuit into a self-instrumented, telemetry-reporting component — a direct IoT augmentation of Claim 14.

C8. Emerging Tech — Blockchain-Verified Assembly Torque and Alignment QA

Axis: Integration with Emerging Technology (blockchain)

Enabling Description. Instrument the assembly line for the Claim 14 lock mechanism: a BLE-connected torque wrench records each alignment-plate screw torque (target ±10%), a vision station hashes the post-lock alignment photo to IPFS, and the operator ID and lot number are appended; all records are committed to a permissioned Hyperledger Fabric ledger with an endorsement policy of 2-of-3 (torque tool, vision station, line server). Lot-level traceability enables recall scoping and warranty adjudication based on immutable assembly evidence.

C9. Inverse — Breakaway Sacrificial Flex Connector

Axis: The "Inverse" or Failure Mode

Enabling Description. Design the flex-circuit bridge with a deliberate weak point: a necked-down trace region with a defined shear strength (e.g., 500 gf lateral force) that cleanly severs before the segment frame or display panel suffers damage. An open-circuit detector (pull-up resistor on each trace, sampled at 10 Hz) detects the break and triggers the Claim 1 limp mode. The severed module is field-replaceable via a card-edge connector at the segment boundary, so a single failed seam does not brick the device. This is the intentional-failure inverse of Claim 14: the seam is designed to fail first, safely, and cheaply.

4. Derivative Set D — Claim 19 (Framed Hinge/Sensor/Magnet/Audio Device)

D1. Material Substitution — Ti/CFRP Frame with Ferrofluid Hinge Seal and Piezo Speaker

Axis: Material & Component Substitution

Enabling Description. Substitute the frame material with CNC-machined Ti-6Al-4V or CFRP (T700 carbon fiber, 60% fiber volume fraction, quasi-isotropic layup) for stiffness-to-weight improvement. Replace conventional hinge grease with a ferrofluid (magnetite-in-silicone carrier, e.g., ED-FF-01) retained by a permanent magnet in the hinge cavity, providing zero-leak, low-friction damping across 200,000 cycles. Substitute the dynamic speaker with a 20 mm × 20 mm × 1 mm PZT bimorph piezoelectric speaker bonded to the frame, eliminating the magnet/coil assembly and thinning the compact state. Microphone remains a MEMS die; magnets for state latching remain NdFeB N52. This preserves Claim 19's framed-hinge + sensor + magnet + audio architecture with fully substituted materials.

D2. Operational Parameter Expansion — Industrial Large-Format High-Vibration Variant

Axis: Operational Parameter Expansion

Enabling Description. Scale Claim 19 to an industrial large-format panel: 32-inch-diagonal segments, hinges rated to 20 kg cantilever load, 304 stainless steel hinge bodies, and a 10,000-cycle mechanical rating. Environmental envelope: MIL-STD-810H vibration (Method 514.8, Category 24), -30 °C to +60 °C operating, and IP54 front-panel sealing. State sensors are industrial-grade inductive proximity switches rather than consumer Hall sensors; magnets are potted SmCo for temperature stability. Audio output is a 5 W Class-D amplifier driving a weatherproof horn. This defines the Claim 19 architecture at industrial scale and severity.

D3. Cross-Domain — Military Tactical Foldable Display

Axis: Cross-Domain Application (Defense)

Enabling Description. Apply Claim 19 to a soldier-worn tactical display: 1,000-nit sunlight-readable OLED, NVIS-compatible per MIL-STD-3009 (NVIS Class B), EMI shielded per MIL-STD-461 (CE102/RE102). Hinges are titanium with dry-film lubricant for -40 °C operation; latch magnets are platinum-plated SmCo to resist corrosion and demagnetization. The frame integrates a bone-conduction transducer (the speaker analog) and a noise-canceling MEMS microphone array, both functional in folded (radio) and unfolded (map) states. State sensors are hardened reed switches with redundant wiring. This is a direct military instantiation of Claim 19.

D4. Cross-Domain — Marine Chartplotter with Salt-Fog-Rated Hinges

Axis: Cross-Domain Application (Marine)

Enabling Description. Apply Claim 19 to a marine chartplotter: IP67 enclosure, ASTM B117 salt-fog resistance (500 h), hinges in 316L stainless steel, latch magnets as Ni-Cu-Ni-plated NdFeB to survive saltwater ingress. Display is a transflective LCD or bonded OLED readable in direct sun; the speaker is a marine-rated 2 W piezo horn; the microphone is a water-resistant MEMS with hydrophobic mesh. State sensors are sealed reed switches; compact state = docking/helmsman data, expanded state = full chart. This instantiates Claim 19 in a corrosive, wet environment.

D5. Cross-Domain — Construction Ruggedized Tablet

Axis: Cross-Domain Application (Construction)

Enabling Description. Apply Claim 19 to a jobsite rugged tablet: 1.8 m drop survival per MIL-STD-810H Method 516.8, rubber overmold, hardened steel hinge detents, and glove-friendly projected-capacitive touch (3 mm mutual-capacitance tuning). Latch magnets are over-molded to prevent debris jamming; state sensors are dust-sealed Hall devices. The speaker is a 1 W waterproof transducer; the microphone is a far-field dual-MEMS array with beamforming for noisy jobsite voice commands. Battery: dual hot-swappable 5,000 mAh packs, one in each major segment, managed by the core module. This scales Claim 19's compact/expanded audio-and-sensor architecture to construction severity.

D6. Emerging Tech — IoT Hinge-Angle Telemetry over BLE Mesh

Axis: Integration with Emerging Technology (IoT)

Enabling Description. Instrument each Claim 19 hinge with a 14-bit magnetic angle encoder (AS5048-compatible) sampled at 100 Hz by a Zephyr-RTOS node; nodes form a Bluetooth SIG Mesh network with the core module as the mesh proxy. The phone app visualizes live fold angle, latch state, and per-hinge cycle count; an automation rule (e.g., via Matter/Home Assistant bridge) triggers expanded-state content when hinge angle exceeds 170°. Telemetry is published at 1 Hz in expanded state and 0.1 Hz in compact state to conserve battery. This adds continuous IoT observability to the framed-hinge architecture.

D7. Emerging Tech — AI Predictive Hinge-Wear and Latch-Fatigue Monitoring

Axis: Integration with Emerging Technology (AI)

Enabling Description. Mount a 6-axis IMU at each hinge and collect vibration signatures during every fold event; a 1D-CNN classifier (trained on 10,000 labeled fold cycles from accelerated life testing) maps the signature to a wear index (0–100%). Latch engagement force is inferred from the magnetic-angle encoder's settling transient. The model predicts hinge fatigue with ±5% error at 85% of life and issues a maintenance alert before mechanical failure, enabling predictive rather than reactive service. This applies AI prognostics to the Claim 19 hinge and latch hardware.

D8. Emerging Tech — Blockchain Maintenance and Service Ledger

Axis: Integration with Emerging Technology (blockchain)

Enabling Description. Record every service event on the Claim 19 hardware — hinge replacement, latch magnet re-magnetization, sensor recalibration, firmware update — to a permissioned ledger (Hyperledger Fabric) keyed by hinge serial number and device attestation. A smart contract enforces service intervals (e.g., hinge lubrication every 50,000 cycles) and voids warranty coverage if the ledger shows missed intervals or non-certified parts. This creates an immutable maintenance provenance chain for the mechanical components of the device.

D9. Inverse — Frangible Impact-Release Hinge and Post-Impact Compact Operation

Axis: The "Inverse" or Failure Mode

Enabling Description. Design the Claim 19 hinge for controlled sacrificial failure: 3 mm aluminum shear pins break at 30 N·m impact torque, releasing the expanded-state panel before frame or display damage propagates. After shear, the device automatically latches into the compact state (single-segment mode) via a spring-loaded detent and remains fully operable for telephony and messaging. A field-replaceable hinge cartridge (tool-less, 60-second swap) restores expanded-state function. This is the intentional-failure inverse of Claim 19: the hinge is the designed weak link, prioritizing user data continuity and display survival over structural integrity.

5. Combination Prior Art Scenarios (Open-Source Standards)

Each scenario combines the claimed hardware architecture of US11048300 with a specific open-source standard, in enabling detail, to foreclose future patents on the combination.

CP1. AOSP Foldable Display HAL Integration

Enabling Description. Combine the Claim 1/Claim 9 device with the Android Open Source Project (AOSP) foldable-display software stack: a FoldStateManager HAL (AIDL) exposes the segment-sensor bitmap as a virtual sensor via SensorService; DisplayManager treats the expanded state as a single logical display with Display.Mode switching; WindowManager applies Configuration change callbacks to rescale activities; surface composition uses SurfaceFlinger with per-segment drm_plane assignment. The result is a reference implementation of fold-state-aware content rescaling running entirely on open-source Android components (as later shipped in the Pixel Fold / Galaxy Fold HAL generations).

CP2. Linux DRM/KMS Multi-Segment Compositor

Enabling Description. Combine the Claim 14 segmented display with the Linux kernel Direct Rendering Manager (DRM)/Kernel Mode Setting (KMS) subsystem: the segmented display registers as one logical DRM connector backed by a custom drm_panel driver; each segment is exposed as a writeback connector (DRM_MODE_OBJECT_WRITEBACK) for damage tracking; a virtual CRTC composites per-segment planes with drm_framebuffer damage rectangles. Weston/Mutter compositors consume the connector as a single output, with per-segment atomic commit (DRM_MODE_ATOMIC_NONBLOCK) to avoid tearing during fold-induced resolution changes. This defines an open-kernel implementation of the multi-segment seam.

CP3. Zephyr RTOS Sensor-Fusion Hub

Enabling Description. Combine the Claim 9/Claim 19 sensor suite with the Zephyr RTOS sensor subsystem: each fold-state sensor (Hall, IR, FSR) registers as a Zephyr sensor_device; a fusion driver subscribes via sensor_trigger callbacks and implements the majority-vote state machine as a Zephyr work queue; power management uses Zephyr's PM subsystem to hold the hub at 10 µA sleep with 1 ms wake latency. The hub publishes fold state over Zephyr's settings/shell interfaces for bring-up and field diagnostics. This is a complete open-source RTOS reference for the state-detection method.

CP4. OpenCV Fiducial Alignment Verification

Enabling Description. Combine the Claim 14 alignment-lock with OpenCV's ArUco module: print 4×4_50 dictionary markers on each segment's back panel; after lock engagement, a fixed camera captures the seam, cv2.aruco.detectMarkers locates corners, and cv2.findHomography computes the inter-segment transform. Lock acceptance requires residual RMS error <25 µm; failures trigger a re-lock cycle or service flag. This provides a reproducible, open-source vision-based alignment acceptance test for the locking mechanism.

CP5. Matter / OpenThread Segment Telemetry

Enabling Description. Combine the Claim 19 IoT-instrumented hinges with the Matter smart-home standard: each hinge node is a Matter-enabled endpoint on an OpenThread mesh; the whole device appears as a Matter BridgedDevice; fold state, hinge angle, cycle count, and latch force publish as Matter cluster attributes (custom cluster 0x1305-style vendor extension). A Matter fabric admin (e.g., Home Assistant + Matter bridge) subscribes to fold-state events and drives room automation. This defines the device as a first-class citizen of the Matter ecosystem, with all telemetry flowing over open standards.
