  • Patent number: 12200233
    Abstract: A system and method for limited rate context-based eye gaze encoding includes generating, based on an outward looking camera situated in a vehicle, a first video stream of a surrounding environment to a controller. The controller generates a scene description based on the first video stream and selects a corresponding scene from a predefined list of known scenes. Further, the controller, based on the selected corresponding scene, selects a codebook of encoding and decoding parameters from a plurality of predefined codebooks. Based on an inward looking camera situated in the vehicle, a second video stream of a face of a driver to an eye tracker controller is generated, where the eye tracker controller estimates a gaze direction of the driver. Encoded data comprising the estimated gaze direction of the driver is transmitted over a bandwidth limited channel to a decoder, based on the selected codebook, the encoded data.

  • Patent number: 12196844
    Abstract: Architectures and techniques for radar interference detection are provided. A radar sensor system in accordance with the present disclosure may receive, via a radio frequency (RF) receiver, radar signals including a radar signal of interest and one or more interfering radar signals. The radar sensor system may calculate a Doppler spectrum for each of the radar signals and perform a chirplet transform on the Doppler spectrum to generate various waveform parameters. A Principal Component Analysis (PCA) may be performed on the waveform parameters to extract frequency features of the radar signals. The radar sensor system may classify the frequency features using a classifier to identify interfering frequency features associated with the interfering radar signals using a classifier. The radar sensor system may further extract interfering waveform information based on the interfering frequency features of the interfering RF signals.

  • Patent number: 12194988
    Abstract: Systems and methods of controlling an active safety feature of a vehicle are provided. The systems and methods receive radar data from a radar device of the vehicle and image data from a camera of the vehicle. Object detection and tracking processes are performed on the radar data and the image data to identify and track objects in an environment of the vehicle. Conditions are assessed with respect to identified objects to ascertain whether a radar track is erroneously reported as a separate object to a camera track. When the conditions are assessed to be true, an object corresponding to the camera track is used as an input for controlling an active safety feature of the vehicle and an object corresponding to the radar track is discounted for controlling the active safety feature of the vehicle.

  • Publication number: 20250015412
    Abstract: Excessive expansion of rechargeable batteries during recharging is a significant concern since the uncontrolled buildup of high internal battery pressures from expansion inside a confined space can lead to separator membrane failure and/or thermal runaway of a battery cell. A crushable foam or honeycomb insert layer is placed inside of a rigid battery fixture to automatically limit the progressive buildup of internal battery pressure due to charging-induced expansion of the battery cell during recharging. The crushable insert layer is included as part of the rigid battery fixture. Aluminum honeycomb cores and porous aluminum metal foam materials have a significant amount of crushability over a very wide range of compressive strains. Alternatively, a porous metal foam or metal honeycomb material may be infused with a liquid polymer (e.g., silicone, rubber, EDPM, or polyurethane) to enhance the mechanical properties of the polymer-infused metal foam or honeycomb metal/polymer composite material.

  • Publication number: 20250015384
    Abstract: A mechanical design of a rechargeable battery cell (e.g., a Lithium-ion battery) disposed inside of a prismatic can, for use in electric vehicles and other electric-powered devices. The improved design uses a thermally conductive insert to divide the battery cell into two adjacent volumes that each hold a pair of stacked layers of a battery cell. This thermally conductive insert conducts heat from the center of the battery cell during battery recharging to actively-cooled channels disposed in a pair of cooling manifolds that are disposed on two vertical sides of the battery cell. Alternatively, or additionally, an actively-cooled bottom cold plate can be used. The pair of stacked battery layers can each be wound in a “jelly-roll” geometric configuration. The thermally conductive insert may be made of aluminum, aluminum alloy, copper, or copper alloy, and combinations thereof.
