US Patent 10,890,925 Summary

• Title: Vehicle leveling systems, devices and methods and computer program products for leveling vehicles using smart devices

• Current Assignee: ETN Capital LLC

• Inventor: Charles A. Leonard

• Filing Date: June 9, 2017

• Issue Date: January 12, 2021

• Abstract: The patent describes leveling systems and processes for leveling vehicles, such as recreational vehicles, and related computer program products using smart devices. The system includes a sensor device secured to a vehicle to detect its inclination or orientation in both pitch and roll directions. A smart device communicates with this sensor device, processes the received information, provides measurements to a user, and determines the necessary height adjustments in either the pitch or roll direction to level the vehicle.

• Plain-Language Overview of Independent Claims:

  • Independent Claim 1: This claim describes a vehicle leveling system. It includes at least one sensor device attached to a vehicle (like an RV) to measure its tilt (pitch from front-to-back and roll from side-to-side). This sensor device contains a printed circuit board (PCB) with a processor, firmware, a digital accelerometer, and a digital temperature sensor. The system also includes a smart device (like a smartphone or tablet) with a software application. The smart device communicates wirelessly with the sensor device and stores its measured pitch and roll angles when the vehicle is at a known "initial level position" as calibration data. When the vehicle needs leveling, the sensor device measures its current pitch and roll angles, along with the temperature. The firmware on the sensor device's PCB uses this current temperature to correct any inaccuracies in the angle measurements based on a stored temperature calibration lookup table. Then, it uses the corrected current angle measurements and the stored calibration data to calculate how much the vehicle needs to be adjusted in height in the pitch and roll directions to return to the initial level position. This calculated adjustment information is then sent to the smart device and displayed to the user.
  • Independent Claim 13: This claim describes a method for leveling a vehicle. First, a leveling system is provided, which includes at least one sensor device attached to a vehicle (such as an RV) to detect its inclination or orientation in pitch and roll, and a smart device in wireless communication with the sensor device. The method involves measuring the pitch and roll angles of the vehicle using the sensor device when the vehicle is at rest. It also includes the step of the smart device receiving and storing initial level calibration data from the sensor device, which represents the pitch and roll angles when the vehicle was at a determined initial level position. When leveling, the current pitch and roll angles and current temperature are measured by the sensor device. The sensor device's processor and firmware use the current temperature and a temperature calibration lookup table to correct the angle measurements. The method then calculates the necessary change in pitch or roll to achieve the initial level position, using these corrected current angle measurements and the stored calibration data. Finally, this calculated change is displayed on the smart device.
  • Independent Claim 17: This claim describes a non-transitory computer readable medium containing instructions for a software application. When a computer's processor executes these instructions, it performs steps similar to the method of claim 13. Specifically, it receives current pitch and roll angle measurements from a sensor device on a vehicle at rest. It retrieves calibration data (pitch and roll measurements when the vehicle was at an initial level position). It then calculates the needed adjustments in pitch or roll to level the vehicle, using the current measurements, the calibration data, and temperature-corrected sensor data. Finally, it displays this calculated change on a smart device.

## US Patent 10,890,925 Summary

**Title:** Vehicle leveling systems, devices and methods and computer program products for leveling vehicles using smart devices

**Current Assignee:** ETN Capital LLC

**Inventor:** Charles A. Leonard

**Filing Date:** June 9, 2017

**Issue Date:** January 12, 2021

**Abstract:** The present subject matter provides leveling systems and processes for leveling vehicles, such as recreational vehicles. The present subject matter also relates to computer program products for leveling vehicles, such as recreational vehicles, using smart devices. The leveling system can include a sensor device secured to a vehicle to sense at least one of an inclination or an orientation of the vehicle in both a pitch direction and a roll direction. The leveling system can include a smart device in communication with the sensor device to allow information received from the sensor device to be processed to provide measurements to a user and to determine the amount of adjustments needed in height to at least one of the pitch direction or the roll direction to level the vehicle.

**Plain-Language Overview of Independent Claims:**

*   **Independent Claim 1:** This claim describes a vehicle leveling system that guides a user to level a vehicle like a recreational vehicle (RV). The system includes a sensor device attached to the vehicle, which contains a computer chip (PCB) with a processor, software (firmware), a digital accelerometer, and a digital temperature sensor. The system also has a smart device (such as a smartphone or tablet) with a special software application. This smart device communicates wirelessly with the sensor device. When the vehicle is initially level, the smart device saves the pitch (front-to-back angle) and roll (side-to-side angle) measurements from the sensor device as "calibration data." Later, when the vehicle needs to be leveled, the sensor device measures its current pitch and roll angles, along with the temperature. The sensor's firmware uses the temperature to correct any inaccuracies in the angle readings by referencing a stored "temperature calibration lookup table." Then, using these corrected current angles and the saved calibration data, the sensor device or smart device calculates exactly how much the vehicle's height needs to be adjusted in the pitch and roll directions to make it level. This calculated adjustment information is then shown to the user on the smart device.

*   **Independent Claim 13:** This claim outlines a method for leveling a vehicle. It starts by providing the leveling system described in Claim 1 (a sensor device on the vehicle and a smart device communicating wirelessly). The method involves measuring the vehicle's pitch and roll angles when it's still, using the sensor device. It also includes a step where the smart device receives and stores calibration data, which are the pitch and roll angles measured by the sensor when the vehicle was previously set to an initial level position. To level the vehicle, the sensor device measures the current pitch and roll angles and the temperature. The sensor then uses the temperature to adjust these angle measurements based on a stored temperature calibration table. Finally, using these temperature-corrected current angles and the stored calibration data, the system calculates the necessary changes in pitch or roll (and corresponding height adjustments) to make the vehicle level, and this information is shown on the smart device.

*   **Independent Claim 17:** This claim describes a computer program product, specifically non-transitory computer readable media (like software stored on a chip or disk). When a computer processor runs this software, it performs the steps to help level a vehicle. These steps include: receiving current pitch and roll angle measurements from a sensor device on a vehicle at rest; retrieving previously saved "calibration data" (which are pitch and roll measurements from when the vehicle was in an initial level position); calculating the required adjustments in pitch or roll to make the vehicle level, using both the current angle measurements and the calibration data, while also incorporating temperature corrections to the sensor data; and finally, displaying these calculated adjustments on a smart device.

**CAFC 2026 Dockets:**
As of April 26, 2026, searches of CAFC 2026 dockets did not specifically return any active cases directly associated with US Patent 10,890,925. However, the patent's Google Patents page indicates "Family has litigation" with various US district court cases and appeals filed at the Court of Appeals for the Federal Circuit in years prior to 2026 (e.g., 2022, 2023, 2024), and a PTAB case in 2024. There is no authoritative information specifically identifying new CAFC dockets opened in 2026 for this patent.

Title: Vehicle leveling systems, devices and methods and computer program products for leveling vehicles using smart devices

Current Assignee: ETN Capital LLC

Inventor: Charles A. Leonard

Filing Date: June 9, 2017

Issue Date: January 12, 2021

Abstract: The present subject matter provides leveling systems and processes for leveling vehicles, such as recreational vehicles. The present subject matter also relates to computer program products for leveling vehicles, such as recreational vehicles, using smart devices. The leveling system can include a sensor device secured to a vehicle to sense at least one of an inclination or an orientation of the vehicle in both a pitch direction and a roll direction. The leveling system can include a smart device in communication with the sensor device to allow information received from the sensor device to be processed to provide measurements to a user and to determine the amount of adjustments needed in height to at least one of the pitch direction or the roll direction to level the vehicle.

Plain-Language Overview of Independent Claims:

• Independent Claim 1: This claim describes a vehicle leveling system that guides a user to level a vehicle, like a recreational vehicle (RV). The system includes at least one sensor device attached to the vehicle. This sensor device contains a printed circuit board (PCB) equipped with a processor, firmware (embedded software), a digital accelerometer, and a digital temperature sensor. The system also includes a smart device (such as a smartphone or tablet) that communicates wirelessly with the sensor device. The smart device's software application performs several key functions: it saves initial pitch (front-to-back tilt) and roll (side-to-side tilt) angle measurements from the sensor device as "calibration data" when the vehicle is known to be level. When the vehicle later needs leveling, the smart device receives current pitch and roll angle measurements along with temperature readings from the sensor device. The sensor device's firmware then uses these temperature readings and a stored temperature calibration lookup table to correct any inaccuracies in the current angle measurements. Finally, the system calculates the exact height adjustments needed in both pitch and roll directions to bring the vehicle back to its initial level position, using these corrected current angles and the saved calibration data. This calculated adjustment information is then displayed on the smart device for the user.

• Independent Claim 13: This claim describes a method for leveling a vehicle. The method begins by utilizing a leveling system comprising at least one sensor device attached to a vehicle (e.g., an RV) to detect its pitch and roll, and a smart device wirelessly connected to this sensor device. The first step involves measuring the vehicle's pitch and roll angles when it is at rest using the sensor device. Subsequently, calibration data, which are the pitch and roll angle measurements recorded by the sensor device when the vehicle was in a predetermined initial level position, are received from the sensor device and saved on the smart device. To level the vehicle at a new location, current pitch and roll angle measurements, along with current temperature readings, are taken from the sensor device. The firmware on the sensor device then corrects these current angle measurements using the temperature readings and a temperature calibration lookup table. Based on these temperature-corrected current angles and the previously saved calibration data, the method calculates the necessary changes in the vehicle's pitch or roll to achieve a level position. This calculated change is then displayed on the smart device.

• Independent Claim 17: This claim covers a non-transitory computer readable medium (e.g., software stored on a computer chip or hard drive) that contains executable instructions. When a computer's processor runs this software, it performs a series of steps to level a vehicle. These steps include: receiving current pitch and roll angle measurements from a sensor device on a stationary vehicle onto a smart device; retrieving "calibration data" consisting of pitch and roll angle measurements that were recorded by the sensor device when the vehicle was at an initial level position; receiving current pitch and roll angle measurements and temperature readings from the sensor device; correcting these current pitch and roll measurements using the temperature readings and a temperature calibration lookup table via the sensor device's firmware; calculating the required adjustments in either the pitch or roll direction to achieve a level position, using both the corrected current angle measurements from the sensor device and the calibration data; and finally, displaying these calculated adjustments needed to level the vehicle on the smart device.

CAFC 2026 Dockets:
As of April 26, 2026, specific searches of the CAFC 2026 dockets did not directly yield any new case filings or active litigation specifically for US Patent 10,890,925 in the current year. However, the Google Patents information for US10890925 indicates that the "Family has litigation," with prior cases filed in various District Courts and at the Court of Appeals for the Federal Circuit in previous years (e.g., 2022, 2023, 2024), including a PTAB case filed in 2024. Therefore, while there is a history of litigation, no authoritative information on new CAFC dockets specifically opened for this patent in 2026 was found.

Proceedings overview

One AIA trial proceeding, IPR2024-01445, has been filed against US Patent 10,890,925 and terminated via settlement. This provides a defendant with a degree of clarity, as the proceeding did not result in a Final Written Decision on the merits, indicating no claims were definitively invalidated or sustained by the PTAB.

IPR2024-01445 — Unified Patents, LLC v. ETN Capital LLC

• Type: Inter Partes Review
• Filed: 2024-03-29
• Status: Terminated - Settlement
• Judge panel: Not publicly available due to termination before institution decision.
• Petition grounds: Details of the petition grounds (claims challenged, art, statutory basis) are not publicly available as the case was settled before an institution decision was rendered.
• Institution decision: The proceeding was terminated due to settlement before a decision on institution was made by the PTAB.
• Final Written Decision: No Final Written Decision was issued as the case was terminated via settlement.
• Settlement / termination: The proceeding was terminated via settlement, recorded on 2024-03-29. The specific terms of the settlement are confidential.
• Appeal: Not applicable, as no Final Written Decision was issued.
• Defensive value: Since this IPR was settled before institution, no claims were invalidated or confirmed patentable by the PTAB. This means the patent's validity (and specifically, the claims that were challenged) remains untested at the PTAB. A defendant facing assertion can still pursue IPR, as no estoppel would apply based on this terminated proceeding for non-petitioners. For the petitioner (Unified Patents, LLC) and its privies, estoppel under § 315(e)(2) might apply to the specific grounds raised in their petition, even if not fully adjudicated.

Strategic summary

Currently, all claims of US Patent 10,890,925 remain UNTESTED at the PTAB with a definitive ruling. The single AIA trial proceeding, IPR2024-01445, was filed against the patent but terminated due to settlement before the institution stage. This means no claims were canceled, nor were any definitively sustained as patentable by the PTAB.

Regarding the estoppel landscape, since IPR2024-01445 was terminated via settlement before a final written decision, the statutory estoppel provisions of § 315(e)(2) would not apply to the general public or other potential petitioners. However, the petitioner (Unified Patents, LLC) and their privies might face common law estoppel or contractual restrictions based on the settlement agreement regarding the specific grounds they raised or reasonably could have raised. For a new defendant currently being asserted against, the full range of prior-art grounds under § 102 and § 103 against all claims remains available for a potential new IPR petition.

As for pattern signals, the filing of IPR2024-01445 by Unified Patents, LLC suggests that the patent was perceived as asserted against their members or community, leading to a defensive challenge. The settlement indicates a resolution between those specific parties, but not a public adjudication of the patent's validity. There is no evidence of aggressive PTAB appeals by the patent owner or multiple IPRs by the same petitioner beyond this single, settled case.

Recommended next steps

• Since IPR2024-01445 was terminated via settlement before institution, the underlying patentability of the claims remains unadjudicated by the PTAB. If you are a defendant facing assertion of this patent, consider conducting a thorough prior art search to identify potential grounds for a new Inter Partes Review petition. The absence of a Final Written Decision means there is no PTAB ruling to overcome, potentially making an IPR a viable defensive strategy.
• Review the terms of the settlement for IPR2024-01445, if publicly accessible, to understand any specific carve-outs or agreements, though such terms are typically confidential.
• Monitor the USPTO PTAB E2E system for any new filings against US10890925. The absence of further PTAB activity after the settlement of IPR2024-01445 could suggest reduced assertion activity or a successful private resolution for the petitioner.

Inventors

"ETN Capital LLC" as the current assignee, combined with "DBA Beech Lane" in the preceding license (Reel 069279/0146), suggests a rebranding or an entity primarily focused on asset management or monetization rather than direct product manufacturing and sales under its primary name.

2. Known asserter in the chain — unclear. While "ETN Capital LLC" and "FBA OPERATING CO" have names that could suggest a non-practicing entity, they do not directly match the provided list of known high-frequency NPEs (Acacia Research Corp, Marathon Patent Group, etc.) as of the current date.

3. Repeat correspondent across the chain — present.

   • Kathryn M. Lorenzen of Debevoise & Plimpton LLP appears as the correspondent for multiple entries:
     • 2024-03-15 (executed) / recorded 2024-03-20 — Reel 066789/0628 (Security Interest)
     • 2024-03-29 (executed) / recorded 2024-03-29 — Reel 066848/0468 (Corrective Assignment)
     • 2025-07-28 (executed) / recorded 2025-08-01 — Reel 069279/0146 (License)
     • 2026-01-28 (executed) / recorded 2026-02-05 — Reel 070213/0550 (Release of Security Interest)
     • 2026-02-12 (executed) / recorded 2026-02-19 — Reel 070274/0937 (Assignment of Assignor's Interest)
       This recurrence across various conveyance types and assignees (FBA OPERATING CO., MIDCAP FINANCIAL TRUST, MIDCAP FUNDING IV TRUST, ETN CAPITAL, LLC) is a strong signal.

4. Cascading transfers — present.

   • Multiple consecutive assignments and related conveyances occurred within a relatively short period:
     • 2024-03-15 (executed) / recorded 2024-03-20 — Reel 066789/0628 (Security Interest)
     • 2024-03-29 (executed) / recorded 2024-03-29 — Reel 066848/0468 (Corrective Assignment)
     • 2025-07-28 (executed) / recorded 2025-08-01 — Reel 069279/0146 (License)
     • 2026-01-28 (executed) / recorded 2026-02-05 — Reel 070213/0550 (Release of Security Interest)
     • 2026-02-12 (executed) / recorded 2026-02-19 — Reel 070274/0937 (Assignment of Assignor's Interest)
       This rapid succession of transfers and agreements, especially involving securitization, licensing, and final assignment, all within less than 24 months, indicates a pattern often associated with monetization strategies.

5. Pre-litigation transfer — unclear. While the Google Patents page shows "Family has litigation" with cases filed from 2022 onwards, the specific dates of the assignments (starting with FBA OPERATING CO in 2022) are close to or after some of these litigation filings, making it difficult to definitively tag any specific assignment as "pre-litigation" without more precise litigation filing dates for this specific patent.

6. Bankruptcy fire-sale — not present. There is no indication from the assignment records or patent text that any assignor declared bankruptcy.

7. Privateering — unclear. There is no direct evidence from the provided records (such as SEC filings or specific industry coverage) to suggest privateering.

8. Defensive aggregator (anti-NPE) — not present. The current assignee, ETN Capital LLC, is not a known defensive aggregator.

Verdict

NPE — high confidence. This verdict is driven by multiple strong signals. The patent transitioned from an original operating company (Command Electronics, LLC) to entities with "OPERATING CO" and "CAPITAL, LLC" in their names (FBA OPERATING CO, Reel 058140/0178; ETN CAPITAL, LLC, Reel 070274/0937), which are common designations for shell entities involved in patent monetization. Furthermore, the presence of a repeat correspondent, Kathryn M. Lorenzen, across multiple, rapid-fire transactions (Reel 066789/0628 through Reel 070274/0937) from 2024 to 2026, including security interests, licenses, and assignments, strongly indicates a coordinated monetization strategy. The cascading transfers themselves within a short timeframe also reinforce this pattern.

USPTO Assignment Center search for US10890925

The USPTO provides a "Patent Public Search" tool for searching patents and patent application publications. I will use this to identify the most relevant prior art for US patent 10890925.

The prompt requires extracting information directly from US10890925 for prior art citations. I will reference the "Prior Art Citations" section of the patent itself, as this lists the references considered by the patent examiner during prosecution.

For each cited patent, I will provide:

1. Full citation: As listed in the patent.
2. Publication/Filing date: From the patent citation or an external search if needed.
3. Brief description: Based on the title and/or abstract of the cited patent (if available in the patent text or through a quick search).
4. Which claim(s) it potentially anticipates under 35 U.S.C. § 102: This requires a detailed analysis that is outside the scope of a brief description without direct access to the full text of each cited prior art and a comprehensive claim chart. Therefore, I will state that this determination would require a more in-depth legal analysis of each prior art reference against the claims of US10890925. However, I can infer general relevance based on the titles and broad descriptions of the cited prior art.

I will now extract the prior art citations from the full patent text provided in the prompt.

• Identify combinations of prior art references.
• Explain why a person having ordinary skill in the art would have been motivated to combine them.
• Determine if such combinations would render the claims of US patent 10890925 obvious.

To determine the patent term adjustments (PTA), patent term extensions (PTE), continuation/divisional applications, related family members, and the projected expiration date for US patent 10890925B2, I need to consult the official USPTO records for this specific patent. The provided search results offer general information about PTA and PTE but do not contain specific details for US10890925B2.

Patent Term Adjustments (PTA) and Patent Term Extensions (PTE):

• PTA: Patent Term Adjustment extends the term of a U.S. patent to compensate for delays by the USPTO during prosecution of utility or plant patent applications. This adjustment is added to the standard 20-year patent term from the filing date. Delays can arise if the USPTO fails to: issue an office action within 14 months, respond to a reply or appeal within four months, act on an application within four months after certain decisions, or issue a patent within four months after paying the issue fee. Additionally, PTA is granted if the application is pending for more than three years, excluding applicant-caused delays. The USPTO automatically determines the PTA and issues a notice with the patent.
• PTE: Patent Term Extension (PTE) is primarily relevant for products with long development and/or regulatory approval lifecycles, such as pharmaceuticals. No information in the provided text or search results specifically indicates that US10890925B2 has received a PTE.

Defensive Disclosure: Derivatives of US Patent 10890925B2 for Prior Art Generation

This document outlines derivative variations of US Patent 10890925B2, focusing on rendering future incremental improvements by competitors obvious or non-novel. The analysis is based on the core independent claims of the patent, specifically Claim 1 (System) and Claim 11 (Method).

Introduction

The objective of this defensive disclosure is to preemptively address potential future patent claims related to vehicle leveling systems, particularly those leveraging smart devices. By publicly disclosing various technical alternatives, operational expansions, cross-domain applications, integrations with emerging technologies, and failure modes, we aim to establish a broad base of prior art that makes incremental advancements in this field obvious to a person having ordinary skill in the art (POSITA). This strategy focuses on expanding the scope of what is considered "known" in the art, thereby limiting the patentability of future similar inventions.

Derivative Variations for Claim 1 (System)

Claim 1: A leveling system for a vehicle comprising: one or more sensor devices secured to the vehicle to sense at least one of an inclination or an orientation of the vehicle in both a pitch direction and a roll direction; and a smart device in communication with the one or more sensor devices, the smart device comprising: a display screen; a wireless communication module configured to communicate with the one or more sensor devices; and a processor configured to execute a software application, the software application configured to: receive from the one or more sensor devices a pitch angle measurement and a roll angle measurement of the vehicle when the vehicle is at rest; retrieve calibration data of pitch and roll angle measurements taken by the one or more sensor devices when the vehicle was at an initial level position; calculate any needed change in at least one of a pitch direction or a roll direction of the vehicle using the received pitch angle measurement and the received roll angle measurement of the at rest vehicle and the calibration data of the pitch and roll angle measurements to obtain a level position of the vehicle; and display on the display screen of the smart device the calculated change in at least one of the pitch direction or the roll direction of the vehicle needed to obtain the level position of the vehicle.

1. Material & Component Substitution

Derivative 1.1: Piezoelectric Strain Gauge Array for Inclination Sensing

• Enabling Description: The one or more sensor devices are replaced with a distributed array of micro-electromechanical systems (MEMS) piezoelectric strain gauges affixed to critical structural points of the vehicle chassis. These gauges continuously measure localized strain, which is then correlated to global pitch and roll inclination through a pre-calibrated finite element analysis (FEA) model. The output signals from the strain gauges are fed into an analog-to-digital converter (ADC) on a local microcontroller (e.g., ESP32-S3), which then transmits the digitized strain data wirelessly via Bluetooth Low Energy (BLE 5.2) to the smart device. The smart device's application uses the FEA model to infer pitch and roll angles from the strain data and computes required adjustments. This approach eliminates traditional accelerometers and gyroscopes, offering resilience to vibration and shock.

Derivative 1.2: Liquid Metal Tilt Sensors with Inductive Readout

• Enabling Description: The inclination sensing is performed by a series of encapsulated liquid metal (e.g., Galinstan) tilt sensors. Each sensor consists of a small reservoir of liquid metal and multiple inductive coils arranged around it. As the vehicle inclines, the liquid metal shifts, changing the mutual inductance between the coils. This change is precisely measured by a high-frequency alternating current (AC) excitation circuit and an impedance analyzer integrated into a custom ASIC within the sensor device. The ASIC converts the impedance changes into pitch and roll data, which is then transmitted via a secure Zigbee mesh network to a gateway, then relayed to the smart device via Wi-Fi. This provides a robust, contact-less, and potentially more stable measurement in certain environments.

Derivative 1.3: Fiber Optic Gyroscopes (FOGs) for High-Precision Angular Rate Sensing

• Enabling Description: For ultra-high precision leveling applications, the sensor device integrates miniature Fiber Optic Gyroscopes (FOGs) to measure angular rates for pitch and roll. These FOGs operate on the Sagnac effect, detecting phase shifts in light propagating through coiled optical fibers. The output of the FOGs is processed by a dedicated digital signal processor (DSP) to integrate angular rates into precise angle measurements, correcting for drift using an onboard Kalman filter combined with occasional static accelerometer readings. The corrected pitch and roll data are then encrypted (AES-256) and transmitted via a proprietary 433 MHz radio frequency (RF) protocol to the smart device.

The smart device is a hardened industrial tablet or a proprietary in-cab display unit, communicating over a robust industrial Ethernet (e.g., EtherCAT) or a private 5G network for reliable, real-time data transfer. The system calculates and displays multi-point leveling requirements (e.g., for each outrigger) and can integrate with the vehicle's hydraulic control unit (HCU) for semi-automatic or fully automatic dynamic leveling during operation or deployment, with a tolerance of ±0.1 degrees across vehicle lengths exceeding 20 meters.

The sensor device utilizes specialized cryogenic-compatible optical inclinometers (e.g., based on optical beam deflection) or capacitive sensors with ultralow thermal expansion coefficients, mounted on the magnet support structure. These sensors operate down to 4 Kelvin. The "smart device" is a remotely located control computer that processes the sensor data, communicated via cryo-compatible fiber optic cables to avoid thermal load and electrical interference. The system calculates and displays minute angular deviations (e.g., in microradians) and suggests adjustments to motorized cryogenic jacks or active vibration isolation platforms.

Communication with the "smart device" (a topside control console on a research vessel) is achieved via an acoustic modem (e.g., using WHOI acoustic protocols) or a tethered fiber-optic cable for data transmission and command signals. The software application calculates pitch and roll deviations and provides instructions for adjusting variable buoyancy tanks or deployable hydraulic legs to stabilize the subsea structure.

These sensors continuously stream data via a long-range wireless protocol (e.g., LoRaWAN) to a cloud-based AI engine. The AI engine, using machine learning models trained on historical leveling data, terrain topology, and weather forecasts, not only calculates immediate leveling adjustments but also predicts future leveling requirements based on anticipated ground settlement, payload shifts, or environmental changes (e.g., soil saturation). The smart device (user's smartphone or an integrated vehicle display) receives these AI-optimized predictive adjustment recommendations, potentially even before the vehicle comes to a complete rest, for more efficient leveling. Blockchain is used to verify the integrity and origin of sensor data for auditing and insurance purposes.

Derivative 4.2: Real-time Leveling using Edge AI and LiDAR-based Terrain Mapping

• Enabling Description: The sensor device integrates a solid-state LiDAR scanner with an edge AI processor (e.g., NVIDIA Jetson Nano) to perform real-time 3D terrain mapping around the vehicle. Concurrently, a high-resolution IMU provides precise vehicle attitude data. The edge AI processor analyzes the LiDAR point cloud to identify optimal leveling points and detect potential obstacles or unstable ground. It combines this terrain analysis with IMU data to calculate instantaneous multi-point leveling adjustments that are displayed on the smart device (e.g., augmented reality overlay on the vehicle's surroundings shown on the smart device's camera feed). This system allows for proactive, real-time leveling guidance before or during minor repositioning, minimizing manual trial-and-error. Calibration data includes a virtual "perfect ground plane" derived from initial setup.

5. The "Inverse" or Failure Mode

Derivative 5.1: Low-Power "Guardian" Mode for Long-Term Storage

• Enabling Description: The leveling system includes a "Guardian Mode" for extended vehicle storage. In this mode, the sensor device (e.g., a low-power MEMS accelerometer with integrated microcontroller) transitions to a deeply sleep-cycled state, waking only once every 24-48 hours. During its brief awake cycle, it takes a single, low-resolution pitch and roll measurement, compares it against a pre-set "storage level" threshold (e.g., ±2 degrees from perfectly level), and logs the data locally. If the deviation exceeds the threshold, it triggers a low-power, single-packet data transmission via a narrow-band IoT (NB-IoT) cellular module to the smart device (or associated cloud service) as an alert. No continuous display or complex calculations are performed, conserving battery life for months or years.

Derivative 5.2: Safe-Fail Emergency Leveling for Damaged Vehicles

• Enabling Description: In the event of a vehicle-damaging incident (e.g., tire blowout, suspension failure), the leveling system enters a "Safe-Fail Emergency Leveling" mode. This mode prioritizes stability over perfect level. The sensor device, which includes redundant accelerometers and gyroscopes, continuously monitors for rapid, uncontrolled changes in pitch and roll or excessive vibration indicative of damage. Upon detection, the smart device application immediately overrides normal leveling algorithms. Instead, it calculates the minimum adjustments required to stabilize the vehicle at its current highest load-bearing points, preventing further collapse or tip-over, rather than achieving a perfectly level state. The display provides urgent, simplified instructions for manual intervention or directs an automated system to deploy emergency stabilizing jacks to pre-defined, mechanically secure positions. The system avoids attempting to achieve a precise "level" which could exacerbate instability on a compromised structure.

Derivative 5.3: Limited-Functionality "Manual Override" Mode

• Enabling Description: Should the wireless communication link between the sensor device and the smart device fail, or if the smart device's battery is depleted, the sensor device itself enters a "Manual Override" mode. The sensor device, equipped with a simple onboard microcontroller and a small, segmented LED display or a series of indicator lights, continues to calculate approximate pitch and roll deviations. Instead of transmitting data, it uses a pre-programmed visual code (e.g., specific LED patterns or numeric codes on the segmented display) to indicate general direction and magnitude of tilt (e.g., "Left High," "Front Low," "Adjust +2 units"). This provides basic, standalone leveling guidance without the need for the smart device, enabling essential functionality even in degraded conditions.

Combination Prior Art Scenarios

These scenarios combine the teachings of US10890925B2 with existing open-source standards to further expand the prior art landscape.

1. US10890925B2 + ROS (Robot Operating System) for Autonomous Vehicle Levelling:

   • Description: The core sensing and calculation methodology of US10890925B2 is integrated into an autonomous ground vehicle (e.g., a robotic platform for surveying or logistics) running a Robot Operating System (ROS) framework. The sensor device (IMU, inclinometers) publishes pitch and roll data as ROS topics. The smart device functionality (processing, display, adjustment calculation) is implemented as a ROS node. This node subscribes to the sensor data, computes desired leveling actions, and publishes command messages to actuator nodes (e.g., controlling a robotic leg or active suspension system). The ROS standard provides a robust, modular, and open-source software architecture for developing and deploying robotic applications, making the integration of leveling capabilities an obvious extension for autonomous vehicles requiring stable platforms. This combination would demonstrate an obvious integration of patent claims with a widely adopted open-source robotics framework.
   • Prior Art Value: Establishes the use of the core leveling system within a standardized, open-source robotics control architecture for autonomous vehicle leveling.

       D --> G[Smart Device (ROS GUI/RVIZ Display)]
   

2. US10890925B2 + OpenStreetMap (OSM) for Location-Aware Levelling Profiles:

   • Description: The leveling system of US10890925B2 is enhanced by integrating with OpenStreetMap (OSM) data. The smart device's software application utilizes the vehicle's GPS location to query OSM for terrain elevation data, parking lot gradients, or specific user-contributed "leveling profiles" associated with known camping spots or industrial sites. This allows the system to proactively retrieve or suggest optimal initial leveling strategies based on geospatial information, rather than purely reactive measurements. For instance, if OSM indicates a known slope at a particular campground spot, the system could pre-calculate and display approximate block heights needed for the uphill side before the vehicle even pulls in fully. The OSM data is an open-source, crowd-sourced geographic database.
   • Prior Art Value: Demonstrates the obviousness of integrating real-time leveling guidance with publicly available, open-source geospatial data for predictive or enhanced leveling.

       F --> G[Sensor Device (Verification)]
   

3. US10890925B2 + Matter (Open Standard for IoT) for Smart Home Integration:

   • Description: The vehicle leveling system, when parked (e.g., an RV at home or in a smart campground), integrates its sensor device and smart device functionality into a broader Matter-compliant smart home ecosystem. The sensor device's pitch and roll data are exposed as Matter "attributes" through a Matter bridge or directly if the sensor device is Matter-enabled. This allows other smart home devices (e.g., smart lighting, thermostats, automated shades) to react to the RV's level status. For example, if the RV is significantly unlevel, smart lights inside could subtly adjust color to indicate the direction of tilt, or smart blinds could automatically adjust to compensate for perceived unevenness. The "smart device" acts as a Matter controller.
   • Prior Art Value: Shows the straightforward integration of vehicle leveling status into common, open-source IoT home automation standards, making the sharing and reactive use of leveling data in a broader context obvious.
