  • Patent number: 11936975
    Abstract: Embodiments include providing a computer vision video stream and a human vision video stream using a single camera. The camera can comprise a single, high-resolution senor and a wide-angle lens providing high resolution video having a wide aspect ratio field of view. The streams can be generated, wherein the computer vision video stream maintains the wide aspect ratio field of view and the human vision video stream comprises high resolution video. The computer vision video stream can be provided to a computer vision system, wherein the computer vision system uses the computer vision video stream as input for an automated process, and the human vision video stream can be provided to a system that displays the human vision video stream to a user.

  • Publication number: 20230204781
    Abstract: A vehicle may perform time of flight (ToF) calculations or determinations using passive sensors (e.g., passive image sensors) with existing onboard vehicle light sources to generate depth data and a depth image of a scene surrounding the vehicle. For example, the vehicle may use an automotive camera (e.g., a passive sensor that does not emit light) and may pair the camera with one or more light sources on the vehicle to construct a ToF camera. To accomplish this construction of a ToF camera using existing automotive cameras and existing light sources, a controller of the vehicle synchronizes the passive automotive cameras to the onboard light sources. In some examples, the vehicle can enable a high dynamic range (HDR) for the ToF cameras by varying properties of the light emitted from the light sources.

  • Patent number: 11345253
    Abstract: A power supply device for a vehicle that includes two or more independent power sources, a simple low-power voltage monitor connected to a fast switch device, an electronic control unit (ECU), and a dedicated standby monitor element. Each power source has a separate path to connect to the load(s). That is to say, a primary path connects the primary power source to the one or more loads, and a backup path connects the backup power source to the one or more loads. Furthermore, each path includes a back-to-back blocking element, which prevents a direct connection between the primary power source and the backup power source. At standby, both or all paths are blocked except the standby monitor, ensuring extremely low quiescent current. When the system is ON, the voltage level of the power system is monitored; if the voltage level drops below a threshold level, then the paths are switched.

  • Patent number: 11104300
    Abstract: Remote devices have replaced keys as a means to access a secure feature of a vehicle. Remote door locks, starters, climate control, trunk openers, etc., have allowed vehicles to be more welcoming and easier to use. However, such functions often rely on radio frequency transmissions that can merely relay signals coming from an authorized device that may allow a nefarious user to access the vehicle or contents therein. By encoding sequence numbers and timestamps within an exchange, a vehicle may determine that an authorized user is too far away to be granted access to the secure feature, thereby denying access to the nefarious user implementing a relay attack on the vehicle.

  • Publication number: 20210006344
    Abstract: Methods, systems, and devices of the present disclosure are directed to providing seamless fault tolerant clock synchronization utilizing redundant reference clocks in a vehicle communication system. Redundant grandmaster clocks may be synchronized by utilizing clock signals sent between physical layers over a network, and derived clocks of network end devices may be synchronized using messages sent by the grandmaster clocks over the same or separate networks. The primary and backup grandmaster clocks may concurrently transmit synchronization messages to the network end devices. In this way, the grandmaster clocks may be synchronized to clock signals, and the network end devices may derive local clocks based on one, some, or all of the received messages transmitted over a network by the grandmaster clocks.
