Abstract: A robotic vehicle is provided with a novel wheel design and a virtual differential transmission. The novel wheels are generally rounded with scallops along the outer periphery permitting secure engagement of irregular terrain structures, such as the rungs of an inclined ladder. The virtual differential transmission employs rotational sensors in independently driven wheels to maintain information on the relative rotational position of left- and right-side wheels. When necessary, the relative rotational position information is used to selectively drive the left- or right-side wheel until the scallops in a left-side wheel are horizontally aligned with the scallops in a right-side wheel. Thus, the virtual differential transmission can realign the scallops in left- and right-side wheels to facilitate their mutual engagement with a terrain structure, such as a ladder rung.

Abstract: A navigation device is disclosed that provides navigational guidance to boats needing to cross a boundary line at a milestone event time. Port and starboard laylines and guidelines may be displayed with the boundary line using wind direction data. The port and starboard layline angles may change with the wind direction, while their lengths may represent a distance traversed by the boat tacking at the port and starboard layline angles for a target time period at a target speed. A predictor line may be displayed extending from the boat in the direction in which the boat is traveling and may have a length indicating a distance traversed by the boat at its current speed until the milestone event time. The predictor line length and color may provide feedback regarding whether the boat will cross the boundary too early or too late given its current speed and direction.

Abstract: A system and method to preserve the integrity of data being extracted from an electronic data recorder (“EDR”) of an electronic control module (“ECM”) makes use of a forensic link adapter (20) and, optionally, a sensor simulator (10) (when the ECM is out of the vehicle). The forensic link adapter (20) has one or more first microprocessors (23) and associated first software which prevent any message being sent by an external network from corrupting the previously recorded data measurements. The data measurements are then extracted, verified, and stored in a separate file. The sensor simulator (10) has one or more second microprocessors (23), associated second software, and a bank of resistors (21) that mimic sensors normally in communication with the ECM. The simulator “tricks” the ECM into thinking it is still in the vehicle by using the replicating vehicle system values the ECM normally sees when in the vehicle.

Abstract: Sounds are generated by an aerial vehicle during operation. For example, the motors and propellers of an aerial vehicle generate sounds during operation. Disclosed are systems, methods, and apparatus for actively adjusting the shape of a propeller blade of an aerial vehicle during operation of the aerial vehicle. For example, the propeller blade may have one or more joints that adjust to alter the shape of the propeller blade. The altered shape of the propeller blade causes the propeller to generate different frequencies of sound as it rotates. By altering multiple propeller blades of the aerial vehicle, the different sounds generated by the different propeller blades may effectively cancel or reduce the total sound generated by the aerial vehicle, and/or alter the total frequency generated.

Abstract: Systems, apparatus, and computer-readable media for verifying operations of vehicle control systems are disclosed. During a test cycle, a vehicle-embedded computer device (VECD) may monitor control modules and/or sensors embedded in a vehicle for control system data (CSD), may generate and report fingerprint based on a combination of the CSD, and may report the fingerprint to a vehicle performance verification system (VPVS). During deployment, the VECD may monitor the control modules/sensors for CSD, may generate and performance results (PRs) based on a combination of the CSD, and may report the PRs to the VPVS. The VPVS may verify whether the control systems of the vehicle are operating as desired based on a comparison of the PRs with the fingerprint. The VPVS may generate and send an alert or flag to a remote device if the control systems of the vehicle are not operating as desired.
