  • Publication number: 20230182585
    Abstract: The present disclosure generally relates to systems and methods for implementing power a power split between a first and a second power source in a fuel cell powertrain system. The method includes receiving an input into a processor of the fuel cell powertrain system, determining an output by the processor, communicating the output by the processor to a system controller and determining a power split by the system controller. The first power source includes a fuel cell system and the second power source is selected from a battery system or an engine, and the input includes a life or health of at least one of the first power source or the second power source.

  • Patent number: 11570382
    Abstract: An image sensor bridge interface is provided. The interface is situated between an image sensor and a processor. The interface comprises an integrated circuit. The integrated circuit comprises a Field-Programmable Gate Array (FPGA) decoupled from both image signals provided from the image sensor and a processor connected to the integrated circuit. The FPGA separates Ultraviolet (UV) and Infrared (IR) data values from image sensor-provided image data and embeds the UV and IR data values within the horizontal blanking, vertical blanking, and/or active video components of a video feed. The video feed provided from the integrated circuit to the processor using a standard video interface, and the processor providing the video feed or providing UV images, IR images, and Red, Green, and Blue (RGB) images separated from the video feed to a computing core of a host device.
