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.
