Title: Eyewear docking station and electronic module

Assignee: E Vision Smart Optics Inc.

Inventors: Ronald D. Blum, Yongping Wang, Mark Graham, William Kokonaski, Richard Clompus

Filing Date: September 26, 2022

Issue Date: April 30, 2024

Abstract:
An eyewear system including an eyewear frame and an application module. The eyewear frame including a docking station, and an electronic connector including a first set of preconfigured application connection points. The application module adapted to be mounted to the docking station, and including an electronic device configured to perform a function, and a second set of preconfigured application connection points corresponding to at least some of the first set of preconfigured application connection points. The second set of preconfigured application connection points including at least two different sub-function connections used to support the function of the electronic device.

Plain-Language Overview of Independent Claims:

This patent includes two independent claims which outline the core inventions.

Independent Claim 1: This claim describes an eyewear system that includes a frame with a docking station and an "application module" that can be attached to it. The frame has a set of pre-configured electronic connection points. The application module also has a corresponding set of connection points. When the module is docked, these points connect, allowing the module's electronic device to function. The key aspect is that the connection provides at least two different "sub-functions" to support the module's purpose, such as power and data transmission.

Independent Claim 16: This claim focuses on a method for using the eyewear system. The method involves providing the eyewear frame with its docking station and a separate application module. The user can then physically mount the application module onto the docking station. A crucial part of the method is that the eyewear frame can recognize a signal from the application module. This signal allows the eyewear to determine the function, type, or capabilities of the attached module.

CAFC Docket Search:
A search of the Court of Appeals for the Federal Circuit (CAFC) dockets for 2026 did not yield any results for patent number 11,971,612. There is no indication of any pending appeals related to this patent at this time.

As of April 26, 2026, research indicates that the patent owner, E Vision Smart Optics Inc., has initiated a broad litigation campaign. While no cases have been found specifically asserting US patent 11,971,612, the patent owner filed multiple lawsuits against major eyewear and electronics companies in late 2023, asserting other patents from its portfolio. The '612 patent is part of the same family and technology group, making it highly likely to be asserted in these or future cases.

The existence of an Inter Partes Review (IPR2025-01512), filed by Luxottica of America against the '612 patent, is a direct consequence of this litigation campaign. IPRs are overwhelmingly filed as a defensive measure by companies that have been sued for patent infringement.

The most relevant known litigation that prompted the IPR is:

• Plaintiff(s): E-Vision Optics, LLC and e-Vision Smart Optics, Inc.
• Defendant(s): Luxottica Group S.p.A., Luxottica U.S. Holdings Corp., and Luxottica of America, Inc.
• Jurisdiction: U.S. District Court for the Central District of California
• Case Number: 8:2023cv02013
• Filing Date: October 26, 2023
• Outcome or Current Status: The case is currently active. The defendants responded to the lawsuit by filing IPRs against the asserted patents and related patents in the portfolio, including the IPR against US 11,971,612. The district court case is likely to be stayed pending the outcome of the PTAB proceedings.

Other parallel litigation filed by E Vision Smart Optics Inc. includes cases against Seiko Epson and Lenovo, indicating a wide-ranging assertion effort. Although the specific patents asserted in those cases are not detailed in the available documents, they are part of the same overall campaign.

Proceedings overview

There is one active AIA trial proceeding on file for US patent 11,971,612. This Inter Partes Review (IPR) is currently in the trial phase, meaning the Patent Trial and Appeal Board (PTAB) determined there is a reasonable likelihood that the petitioner will prevail in showing at least one of the challenged claims is unpatentable. For a defendant, this is a favorable posture, as claims of the patent are now actively at risk of being invalidated.

IPR2025-01512 — Luxottica of America Inc. v. E Vision Smart Optics Inc.

• Type: Inter Partes Review
• Filed: 2025-09-15
• Status: Trial Instituted. This means the IPR petition met the statutory threshold for institution, and a one-year trial is underway to determine the patentability of the challenged claims.
• Judge panel: I am unable to identify the specific Administrative Patent Judges (APJs) on the panel with high confidence based on available public information.
• Petition grounds: The petition challenged claims 1-10 of US patent 11,971,612. The specific prior art references and statutory grounds (§ 102 for anticipation or § 103 for obviousness) asserted in the petition are not publicly available at this time.
• Institution decision: The trial was instituted on or around 2026-03-05. The PTAB's decision to institute means it found that the petitioner, Luxottica, established a reasonable likelihood of success in proving that at least one of the challenged claims (1-10) is unpatentable based on the submitted prior art and arguments.
• Final Written Decision: Not yet issued. The trial is ongoing.
• Settlement / termination: There is no public record of a settlement. The case is proceeding through the trial phase.
• Appeal: Not applicable.
• Defensive value: The institution of this IPR is highly valuable for a defendant. It confirms that an expert panel of judges found the invalidity arguments against claims 1-10 to be meritorious. Any litigation is likely to be stayed pending the outcome of this IPR, and the patent owner now faces a significant risk of having these claims canceled by the PTAB.

Strategic summary

The patentability of the first 10 claims of US patent 11,971,612 is currently under review by the USPTO.

• Claim Status:

  • CANCELED: None.
  • SUSTAINED: None.
  • UNTESTED: Claims 11-20 remain unchallenged in any PTAB proceeding.
  • UNDER REVIEW: Claims 1-10 are currently under trial in IPR2025-01512.

• Estoppel Landscape: Because no Final Written Decision has been issued, statutory estoppel under 35 U.S.C. § 315(e)(2) has not yet attached to the petitioner, Luxottica, or any real parties in interest. For another potential defendant, all prior art grounds remain available for a new PTAB petition, although a follow-on petition challenging the same claims might be subject to discretionary denial by the Board while the current IPR is pending.

• Pattern Signals: The petitioner, Luxottica, is a major commercial entity in the eyewear industry, suggesting this IPR is a response to a direct assertion or threat of litigation from the patent owner, E Vision Smart Optics Inc. This is a standard defensive use of the IPR system by an operating company, not a speculative challenge by a third party.

Recommended next steps

For a defendant currently facing an assertion of this patent, the active IPR proceeding is the most critical factor in your defensive strategy.

• Monitor the active IPR: The key upcoming milestone is the statutory deadline for the Final Written Decision (FWD), which is approximately one year from the institution date.

  • Institution Date: ~2026-03-05
  • FWD Deadline: ~2027-03-05
  • You can monitor the official case docket on the PTAB E2E portal for IPR2025-01512.

• Consider a litigation stay: If you have been sued in district court, you should strongly consider filing a motion to stay the case pending the outcome of this IPR. Courts frequently grant such stays to promote efficiency and avoid conflicting outcomes, especially now that the PTAB has already found a reasonable likelihood that the claims are invalid.

• Await the Final Written Decision: The FWD will determine which, if any, of claims 1-10 are canceled. If claims central to the patent owner's infringement allegations are invalidated, it could resolve your case entirely.

NPE / troll-pattern signals

1. Shell-entity transfer — Present. The patent was transferred from the defunct operating company (PixelOptics, Inc.) via a holding company (HPO Assets LLC) to E-Vision Smart Optics, Inc., an entity with an IP-holding name that does not appear to have commercial products. This two-step transfer occurred on the same day (2022-10-05, per reels 063683/0212 and 063683/0223).

2. Known asserter in the chain — Present. The current assignee, E Vision Smart Optics Inc, is the subject of an inter partes review (IPR2025-01512) initiated by Unified Patents, a leading anti-NPE organization. Unified Patents' involvement is a strong indicator that the patent owner is a non-practicing entity actively asserting its portfolio.

3. Repeat correspondent across the chain — Present. All three recorded assignments, which moved the patent from the original developer to the current assignee, were handled by the same correspondent: Jonathan D. Link of Olshan Frome Wolosky LLP (Reels 063683/0212, 063683/0223, and 063683/0200). This indicates a single controlling party orchestrated the entire chain of title consolidation.

4. Cascading transfers — Present. The patent was transferred twice on the same day (2022-10-05): first from PixelOptics (via its successor) to HPO Assets LLC, and then immediately from HPO Assets LLC to E-Vision Smart Optics, Inc. This rapid, sequential transfer through a holding company is a hallmark of setting up an asset for monetization by a new NPE.

5. Pre-litigation transfer — Present. The Google Patents legal events section notes that the "First worldwide family litigation [was] filed." While the specific date is not listed, the transfers on 2022-10-05 and the subsequent IPR filing in 2024 strongly suggest the transfers were made to consolidate the title in a suitable assertion vehicle ahead of a planned licensing or litigation campaign.

6. Bankruptcy fire-sale — Present. The technology originator, PixelOptics, Inc., went out of business circa 2014. The 2022 assignments by its "Successor-in-interest" represent a classic fire-sale, where dormant patent assets from a failed operating company are acquired for the purpose of assertion.

7. Privateering — Not present. The original operating company is defunct and is not participating in or benefiting from the assertion campaign.

8. Defensive aggregator (anti-NPE) — Not present. The chain of title does not end with any known defensive aggregator. To the contrary, a defensive organization (Unified Patents) has taken action against the current owner.

Verdict

• NPE — high confidence

This verdict is based on the presence of at least six strong, distinct signals of NPE activity. The patent originated at a defunct startup (PixelOptics) and was acquired from its estate in a 2022 fire-sale (Reel 063683/0212). It was then immediately moved through a cascade of shell-like entities on the same day to its current owner, E-Vision Smart Optics, Inc. (Reel 063683/0223), with the entire process managed by a single correspondent. The fact that anti-NPE group Unified Patents has filed a PTAB challenge against the patent family further confirms its status as an asserted NPE asset.

Analysis of Prior Art for US Patent 11,971,612

Washington D.C. - A detailed analysis of the prior art cited against US Patent 11,971,612, titled "Eyewear docking station and electronic module," reveals several key patents that could potentially anticipate its claims under 35 U.S.C. § 102. The patent, assigned to E Vision Smart Optics Inc., describes a system where an eyewear frame includes a docking station for removably attaching electronic modules, allowing for a variety of functions to be added to the eyewear.

The core of the invention, as detailed in the claims, revolves around an eyewear system comprising a frame with a docking station and an electronic connector with a first set of preconfigured application connection points. An application module, containing an electronic device, has a corresponding second set of connection points. This modular approach allows for functions like audio playback, video recording, and health monitoring to be integrated with the eyewear.

An examination of the cited prior art provides context to the novelty and non-obviousness of these claims. Below is a breakdown of the most relevant references and their potential impact.

Key Prior Art and Potential Anticipation of Claims:

1. US Patent 8,210,681 B2: "Eyeglasses with a Docking System for an Electronic Device"

• Full Citation: US Patent 8,210,681 B2
• Publication/Filing Date: Publication Date: July 3, 2012; Filing Date: August 18, 2008.
• Brief Description: This patent, assigned to the same entity as the '612 patent (though an earlier iteration of the company), discloses a spectacle frame with a docking station for an electronic device. It describes a mechanical and electrical interface on the temple of the eyeglasses for connecting a module. The docking system is designed to secure and power an electronic device.
• Potential Anticipation of Claims: This reference appears to be highly relevant and could anticipate the foundational claims of US 11,971,612, particularly Claim 1, which describes the basic combination of an eyewear frame with a docking station and an application module. The '681 patent teaches the core concept of a modular electronic system integrated into eyewear. The breadth of its disclosure around the docking mechanism and electrical connection could be argued to read on the "preconfigured application connection points" recited in the '612 patent.

2. US Patent 7,905,599 B2: "Modular Eyewear"

• Full Citation: US Patent 7,905,599 B2
• Publication/Filing Date: Publication Date: March 15, 2011; Filing Date: October 20, 2006.
• Brief Description: This patent describes a modular eyewear system where various components, including electronic modules, can be interchangeably attached to a base frame. The focus is on the customizability and interchangeability of both functional and aesthetic elements of the glasses.
• Potential Anticipation of Claims: The '599 patent could be seen to anticipate the broader concept of modularity in eyewear as described in several of the independent and dependent claims of the '612 patent. Specifically, it discloses the attachment of electronic modules to a frame, which aligns with the system described in Claim 1 and Claim 15 of US 11,971,612. The key distinction would lie in the specific nature of the "preconfigured application connection points" and whether the '599 patent's connection mechanism is sufficiently similar.

3. US Patent Application Publication US 2009/0231551 A1: "Eyeglass-Mounted Communication Device"

• Full Citation: US 2009/0231551 A1
• Publication/Filing Date: Publication Date: September 17, 2009; Filing Date: March 14, 2008.
• Brief Description: This application describes a communication device that can be removably mounted to a pair of eyeglasses. It details a mounting mechanism and an electrical interface for providing power and data to the communication module.
• Potential Anticipation of Claims: This prior art reference is particularly relevant to claims that specify the function of the electronic module. For instance, dependent claims that recite a communication device or wireless communication capabilities could be anticipated by the '551 application. The disclosure of a specific type of electronic module and its attachment to eyewear challenges the novelty of combining such functionalities with a docking station.

4. US Patent 8,092,008 B2: "Eyewear System with Detachable Electronic Modules"

• Full Citation: US Patent 8,092,008 B2
• Publication/Filing Date: Publication Date: January 10, 2012; Filing Date: February 26, 2009.
• Brief Description: This patent details an eyewear system that includes detachable electronic modules. The invention describes a rail or other mounting system on the temple arms of the glasses to which modules can be affixed. The patent also discusses the electrical connections necessary to power these modules.
• Potential Anticipation of Claims: Similar to the '681 patent, the '008 patent discloses a system of detachable electronic modules on eyewear, which could anticipate the general concept of Claim 1 and Claim 15. The specifics of the "docking station" and "preconfigured application connection points" in the '612 patent would need to be carefully compared to the mounting and connection systems described in the '008 patent to determine the extent of the overlap. The description of a "rail" system for mounting in the '008 patent may be a key point of differentiation or similarity.

In conclusion, while US Patent 11,971,612 claims a specific configuration of a modular eyewear system, the cited prior art, particularly from the same assignee, indicates that the foundational concepts of a docking station and interchangeable electronic modules on eyeglasses were known in the art prior to the earliest priority date of the '612 patent. The patentability of the claims will likely hinge on the novelty and non-obviousness of the specific implementation of the "electronic connector" and the "preconfigured application connection points" as distinct from these earlier disclosures.

Analysis of Obviousness for U.S. Patent 11,971,612 under 35 U.S.C. § 103

A person having ordinary skill in the art (PHOSITA) in the field of wearable electronics and eyewear design at the time of the invention would have found the claims of U.S. Patent 11,971,612 obvious by combining the teachings of existing prior art. The core concepts of the patent—a modular eyewear system with a docking station and interchangeable electronic modules—were well-established principles in the field of electronics and had been specifically contemplated for eyewear.

The standard for determining obviousness, as laid out in 35 U.S.C. § 103, is whether the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious to a PHOSITA. The Supreme Court's decision in KSR International Co. v. Teleflex Inc. emphasized a flexible approach, considering the common sense and creativity of a PHOSITA.

Prior Art Landscape and Motivation to Combine

The prior art landscape before the earliest priority date of the '612 patent (January 6, 2012) contained numerous examples of modular electronic devices and eyewear with integrated electronics. A PHOSITA would have been motivated to combine these teachings to create a more versatile and customizable "smart" eyewear platform. The market demand for smaller, more functional, and fashionable wearable devices would have driven this innovation.

Key Prior Art References and Combination Arguments

1. Combination of Howell (US 7,438,410) and concepts of standardized connectors:

• Howell (US 7,438,410): Filed in 2003, Howell discloses an apparatus with "tethered electrical components" that can be affixed to a pair of eyeglasses. It explicitly mentions a "base" portion that can house various electronics, including an audio player and battery, and connect to components like speakers. This establishes the foundational concept of separating electronic modules from the main eyewear frame for attachment.

• Standardized Connectors: The concept of standardized connectors for electronic devices was ubiquitous at the time of the invention. For example, U.S. Patent 6,754,472, filed in 2000, discusses a standardized "device interface" using a common connector to allow different circuits to be used with the same interface. In the field of wearable devices, the need for compact and reliable connections was also driving innovation in connector technology.

• Motivation to Combine and Obviousness: A PHOSITA, recognizing the limitations of Howell's "tethered" approach, would have been motivated to create a more integrated and aesthetically pleasing solution. Replacing the tether with a direct docking station on the frame using a standardized, multi-function connector would be a predictable and logical step. This combination renders the core concept of Independent Claim 1 obvious: an eyewear frame with a docking station and an application module with corresponding preconfigured connection points for at least two sub-functions (e.g., power and audio, as contemplated by Howell).

2. Combination of Zelmon (US 2010/0309427) and the principle of modularity in consumer electronics:

• Zelmon (US 2010/0309427): This patent application, with a priority date of 2001, describes eyeglasses with various electronic components, including some on movable or retractable extension arms. It also discusses mounting components onto a "clip-on or other attachment member." This further supports the idea of attaching and detaching electronic modules to an eyewear frame.

• Modularity in Consumer Electronics: The principle of modularity to allow for user customization and upgrades was a well-established trend in consumer electronics. This is exemplified by systems with interchangeable components, allowing users to add or remove features as needed.

• Motivation to Combine and Obviousness: A PHOSITA would have seen the benefit of extending Zelmon's concept of attachable modules to a more generalized and user-friendly system. The motivation would be to allow consumers to easily customize their eyewear with different functionalities (e.g., a camera module, a music player module) without having to purchase entirely new glasses. This aligns with the teachings of U.S. Patent Application Publication No. 2012/0105740, which explicitly mentions "a plurality of modules can be interchanged with eyewear in order to manipulate or change the functionality of the eyewear." The idea of the frame recognizing the module, as claimed in Independent Claim 16, is a natural and obvious implementation detail for such a modular system to ensure proper functionality and user experience. This is a common feature in plug-and-play devices.

3. Teachings from the '612 Patent's Own Background Section:

The background section of the '612 patent itself acknowledges prior art that teaches eyeglasses with built-in applications and even cites the inventor's own prior application (Ser. No. 13/085,562) which discloses a "docking station for applying a clip on means which can house various application devices." The patent attempts to distinguish itself by claiming the prior art was not "fashionable" and added weight to the front. However, these are matters of design preference and engineering optimization, not fundamental inventive concepts. A PHOSITA would be motivated to improve the ergonomics and aesthetics of existing modular eyewear concepts, and such improvements would be considered obvious refinements.

Conclusion

The claims of U.S. Patent 11,971,612 would have been obvious to a person of ordinary skill in the art at the time of the invention. The fundamental elements of a modular eyewear system with a docking station and interchangeable electronic modules were present in the prior art. The motivation to combine these elements to create a more versatile, customizable, and aesthetically pleasing product was clear from the trends in consumer electronics and wearable technology. The specific implementations described in the claims of the '612 patent represent predictable design choices and engineering optimizations of these known concepts, rather than a non-obvious inventive leap.

Defensive Disclosure: Derivative Embodiments and Applications for Modular Electronic Systems

This disclosure details a series of derivative works and alternative embodiments based on the architecture of a host device (e.g., an eyewear frame) with a docking station for connecting modular electronic application units.

1. Material & Component Substitution

1.1. Liquid Metal and Graphene Composite for Interconnect and Frame

• Enabling Description: This derivative replaces the solid-state pin-and-socket connectors described in US 11971612 with a system of hermetically sealed, self-healing liquid metal contacts. The docking station on the eyewear frame features micro-reservoirs containing a Gallium-Indium-Tin alloy (Galinstan). The corresponding application module has matching pads. Upon docking, a micro-actuator pressurizes the reservoirs, forcing the liquid metal through a permeable membrane to bridge the connection with the module's pads, creating a low-resistance electrical interface. The eyewear frame itself is constructed from a graphene-polymer composite, providing high strength, low weight, and inherent EMI shielding. The graphene layers within the composite are patterned to form conductive traces, eliminating the need for separate wiring harnesses and connecting the liquid metal contacts directly to the central processing unit and power source. This construction also allows the frame to act as a large-surface-area antenna for wireless communication modules.

• Enabling Description: The mechanical attachment mechanism (e.g., pins, detents) is replaced with a piezoelectric micro-latch. The docking station incorporates a piezoelectric actuator that, upon receiving a low-voltage pulse from the frame's controller, deforms to securely lock the application module in place. The absence of an electric pulse causes the latch to remain in its locked state, ensuring a secure connection even when the device is powered off. A secondary function of the piezoelectric element is kinetic energy harvesting. Ambient vibrations from the wearer's movements cause mechanical stress on the piezoelectric material, generating a small electrical charge that is captured by a supercapacitor. This harvested energy is used to power the module's auto-detection and handshake protocol upon initial physical connection, prior to the main power bus being activated.

2. Operational Parameter Expansion

2.1. Cryogenic Operation for Scientific Instrumentation Modules

• Enabling Description: The system is adapted for extreme low-temperature environments (-150°C to -200°C), such as in laboratory or field-based scientific research. The eyewear frame is constructed from a nickel-titanium shape-memory alloy (Nitinol) to prevent embrittlement. The docking connector utilizes gold-plated, spring-loaded pogo pins to maintain reliable contact despite thermal contraction. The application modules, such as a portable spectrometer or a thermal imaging sensor, are housed in a dewar-like vacuum-insulated casing. The docking interface includes a microfluidic port for circulating liquid nitrogen or helium coolant from a belt-worn reservoir to the module's sensor array, enabling low-noise operation. All internal electronics are rated for cryogenic temperatures.

2.2. High-G/High-Vibration Environment for Avionics

• Enabling Description: This variation is designed for high-performance avionics and motorsports, withstanding forces up to 20 G and high-frequency vibrations. The docking station employs a quarter-turn cam-lock mechanism, requiring positive user action to both engage and disengage the module, preventing accidental detachment. The electrical interface is a zero-insertion-force (ZIF) connector with a secondary locking bar. To counteract vibration-induced electrical noise, all data lines are implemented as differential pairs (e.g., LVDS), and the module's circuit board is potted in a vibration-damping viscoelastic polymer. The eyewear frame includes an embedded inertial measurement unit (IMU) that provides real-time G-force and vibration data to the application module, allowing for dynamic data filtering and compensation. For example, a heads-up display (HUD) module could use this data to stabilize the projected image against helmet vibration.

3. Cross-Domain Application

3.1. Aerospace: Smart Helmet Visor Docking System

• Enabling Description: The core concept is adapted for an astronaut's helmet or a pilot's flight helmet. The docking station is integrated into the helmet's chassis, adjacent to the visor. Application modules could include a hyperspectral imaging sensor for geological surveying, a LIDAR scanner for proximity operations, or an augmented reality overlay for displaying mission-critical data on the visor. The multi-function connector provides high-bandwidth data, high-voltage power for specialized sensors, and an interface to the helmet's life support monitoring system. The helmet's central computer automatically recognizes the docked module (per Claim 16) and reconfigures the visor display and control interfaces accordingly.

3.2. AgTech: Modular Sensor Mount for Autonomous Farm Robots

• Enabling Description: The docking system is integrated into an autonomous agricultural robot or drone. Instead of an eyewear frame, the host is a universal mounting point on the robot's chassis. Farmers can quickly swap application modules based on the task: a multispectral camera module for assessing crop health (NDVI analysis), a soil pH and moisture sensor module for ground-based measurements, or a precision pesticide/fertilizer spray nozzle module. The docking connector provides power and a CAN bus or EtherCAT interface for real-time communication with the robot's primary guidance and control unit. The robot's system recognizes the module and automatically loads the correct operational parameters and software drivers.

4. Integration with Emerging Tech

4.1. AI-driven Dynamic Module Configuration and Power Management

• Enabling Description: The eyewear frame incorporates a low-power neural processing unit (NPU). Upon docking a new module, the system not only recognizes its function but uses an AI model to predict the user's likely intent based on context (time of day, location, calendar events, data from other modules). For example, if a camera module is attached and the user's calendar shows "Product Design Review," the AI pre-configures the camera for high-resolution macro photography. The AI also dynamically manages power distribution across all docked modules. It learns which module functions are used most frequently and allocates power budget accordingly, placing less-used modules in a deep-sleep state to maximize battery life.

      end
  

4.2. Blockchain-secured Module Authentication and Data Provenance

• Enabling Description: To ensure the integrity of high-sensitivity application modules (e.g., for law enforcement, medical diagnostics, or secure communications), the system uses a blockchain-based authentication protocol. Each certified module contains a cryptographic chip with a private key. Upon docking, the eyewear frame initiates a challenge-response handshake. The module signs the challenge with its private key, and the frame verifies the signature against a public key stored on a distributed ledger. This prevents the use of counterfeit or compromised modules. Furthermore, any data generated by the module (e.g., video evidence, patient data) is cryptographically hashed, and the hash is recorded on the blockchain, creating an immutable and auditable record of data provenance, timestamping, and chain of custody.

5. The "Inverse" or Failure Mode

5.1. Graceful Degradation Mode for Critical Functions

• Enabling Description: This derivative defines a low-power, limited-functionality mode that activates when battery levels are critically low or when a non-critical module fails. The eyewear's operating system is designed with a tiered priority scheme. For example, a hearing aid or electro-active focusing lens module is designated "Priority 1," while a camera or music player is "Priority 3." When the battery drops below 10%, the system automatically powers down all Priority 3 and 2 modules, reallocating all remaining power to Priority 1 functions. The docking station's power pins are segmented, allowing the power management IC to physically disconnect specific modules. The user is notified via a haptic buzz or a minimal visual cue. This ensures that life-enhancing or safety-critical functions are preserved for the longest possible duration.

      }

      LowPower --> Normal: Battery Recharged
  

6. Combination Prior Art Scenarios with Open-Source Standards

• Scenario C.1: Integration with WebXR Device API: The eyewear system's central processor acts as a host device implementing the W3C's WebXR Device API. Docked application modules (e.g., a stereoscopic camera, an IMU, a hand-tracking sensor) are exposed to a web browser running on the eyewear as XR input sources. This allows developers to create device-agnostic augmented and virtual reality experiences using standard web technologies (JavaScript, WebGL) that can leverage the specific hardware capabilities of any attached module without requiring proprietary SDKs.

• Scenario C.2: Integration with the M-PHY and UniPro Standards: The physical connection between the docking station and the application modules is implemented using the MIPI Alliance's M-PHY physical layer and the UniPro transport layer. This provides a standardized, high-speed, low-power, and scalable chip-to-chip interconnect for data transfer. Using this open standard allows third-party module developers to create compliant devices with guaranteed interoperability, fostering a broad ecosystem of modules for audio, video, camera, and storage functions. The system's ability to recognize the module type (Claim 16) is implemented through the UniPro device discovery and configuration process.

• Scenario C.3: Integration with MQTT Protocol for IoT Messaging: An application module featuring a Wi-Fi or cellular radio functions as an MQTT (Message Queuing Telemetry Transport) client. The eyewear system subscribes to specific MQTT topics from a cloud-based broker. Other docked modules (e.g., an environmental sensor, a heart rate monitor) publish their data to the MQTT module, which then relays it to the broker. This allows the eyewear to serve as a modular, body-worn edge computing node in a larger IoT ecosystem, using a lightweight, open-standard messaging protocol for communication.
