  • Patent number: 11863993
    Abstract: A method for automatic pairing of two devices for wireless communication includes detecting, by a first device, that a second device is in a communicable range of the first device, where the first device has not been paired with the second device for wireless communication. The method may include determining, by the first device, by communicating with a third device, that the second device is paired with the third device. The first device and the third device are also paired previously. The method may include transmitting, by the third device, a key material to the second device. The method may include confirming, by the first device and by the second device, that the key material matches. The method may include establishing, by the first device, a communication link with the second device for wireless communication in response to the key material being a match.

  • Patent number: 11862816
    Abstract: A battery pack includes battery cells and an interconnect board assembly (ICBA) having a dielectric ICB and parallel busbars. A cell tab protrudes from an edge of the cells and joined to the busbars. A dielectric ICB is connected to the busbars at one distal end of the busbars. The dielectric material of the ICB is overmolded onto another distal end such that the ICB wraps around the busbars to form overmolded ends. The overmolded ends are received within a pocket of a bracket to form direct parallel cooling paths to a heat sink. A method of manufacturing the battery pack includes arranging the busbars in parallel, overmolding dielectric material onto ends of the busbars to form overmolded ends, and attaching the busbars to a plastic ICB formed from the dielectric material. The ICBA is then attached to the bracket and cells.

  • Publication number: 20230417572
    Abstract: An autonomous vehicle includes sensors proximate to one or more wheels that capture wheel sensor data describing wheel-road interactions. The wheel sensor data may be processed to determine characteristics of the road as the vehicle travels, describing the relative audible, vibratory, or pressure effects of the wheel-road interaction. The wheel sensor data and/or characteristics may then be used to generate a road sensor map describing locations of received wheel sensor data and/or detected road conditions. The wheel sensor data and/or road sensor map may also be used to refine or correct localization of the AV within the environment. In navigation, the AV may use a prior road sensor map for route planning and control, for example to prioritize movement over relatively smooth roads or to navigate to regions with unmapped or aging road information.
