Abstract: Devices and methods for capturing vehicle undercarriage images are described. In some instances, a mirror assembly may be used to reflect images of portions of a vehicle undercarriage into a field of view of a camera to be captured, e.g., as a vehicle passes over the mirror assembly. Composite images may be reconstructed from the reflected portions of the vehicle undercarriage, and analysis may be performed on those reconstructed, composite images to identify features in the composite vehicle undercarriage images.

Abstract: Methods and systems for capturing and processing audio data of a vehicle engine. In one aspect, a vehicle audio capture system includes a mobile device configured to capture vehicle engine sounds in an audio file and to associate tags identifying one or more vehicle conditions observed during audio capture and reflected in the audio file, and a server configured to process the audio file and expose an application programming interface (API) to provide access to the audio file to one or more data consumer devices. In some instances, a condition report server is configured to access the application programming interface to retrieve a version of the audio file and include data describing the audio file within a vehicle condition report. Additionally, tags may be added to the audio file based on detected engine conditions. Detection of engine conditions may be based on use of trained models.

Abstract: Techniques for using a trained machine learning (ML) model to detect presence of vehicle defects from audio acquired at least in part during operation of an engine of a vehicle. The techniques include using at least one computer hardware processor to perform: obtaining, via at least one communication network, a first audio recording that was acquired, using at least one acoustic sensor, at least in part during operation of the engine; processing the first audio recording using the trained ML model to detect, from the first audio recording, presence of at least one vehicle defect, the processing comprising: generating an audio waveform from the first audio recording, generating a two-dimensional (2D) representation of the audio waveform, and processing the audio waveform and the 2D representation of the audio waveform using the trained ML model to obtain output indicative of presence or absence of the at least one vehicle defect.

Abstract: The hearing device is adapted to automatically requesting an establishment of a communication connection to at least one hearing device support provider. The hearing device support provider may comprise a person knowledgeable in hearing devices, at the hearing device seller and/or at the hearing device manufacturer, and it may comprise a computer with a suitable software. Said automatically requesting said establishment of said communication connection will usually happen, when at least one change in internal status of the hearing device occurs, like a failure or a memory overflow or the upcome of a repeatedly occurring event. The hearing device may by itself decide upon the type of change in internal status, which hearing device support provider to connect to. Typically, at least one long-range communication connection is involved.

Abstract: A system and method is provided for improved monitoring and controlling of mechanically commutated DC motors. The system and method include DC motors, pulse-count driver circuitry for driving the motors, motor position sensing circuitry, and motor control circuitry. The system and method provide for improved motor current waveform sensing that is able to effectively reject false brake pulses, avoid erroneous processing due to fluctuating battery voltage levels, and reduce the sensitivity to variations in motor current signals due to dynamic motor load, manufacturing variation, system aging, temperature, brush bounce, EMI, and other factors. The system and method also include an improved ability to multiplex additional external motor drivers to the motor control circuitry, select between sequential and simultaneous drive modes using an SPI bit, and monitor the system controller for an error condition and simultaneously driver motors in response to the error condition.
