  • Patent number: 10657389
    Abstract: A vehicular structure from motion (SfM) system can store a number of image frames acquired from a vehicle-mounted camera in a frame stack according to a frame stack update logic. The SfM system can detect feature points, generate flow tracks, and compute depth values based on the image frames, the depth values to aid control of the vehicle. The frame stack update logic can select a frame to discard from the stack when a new frame is added to the stack, and can be changed from a first in, first out (FIFO) logic to last in, first out (LIFO) logic upon a determination that the vehicle is stationary. An optical flow tracks logic can also be modified based on the determination. The determination can be made based on a dual threshold comparison to insure robust SfM system performance.

  • Patent number: 10658943
    Abstract: An input power conditioning circuit (PCC) for a switched-mode power converter includes a hybrid full wave rectifier. Hybrid rectification is provided by a main rectifier and a matched virtual junction (VJ) rectifier, both with four-transistor gate fully cross-coupled. The VJ rectifier includes a voltage divider (such as a resistive voltage divider) to generate a virtual junction reference voltage VJ_ref (which can be less than transistor Vth). A power conversion controller (such as a boost controller) includes circuitry (such as an error amplifier) to regulate the input voltage VIN (main rectifier) to be substantially equal to VJ_ref from the VJ rectifier. Hybrid rectification, with VIN regulation, can be used to eliminate reverse (flow back) current, improving power conversion efficiency.
