Abstract: A method for manufacturing a battery cell having electrode foils protruding from a cell pouch includes positioning the cell pouch in a fixture such that distal end sections of the foils extend outward from the fixture. The method includes clamping the distal end sections in a curvilinear guide clamp to cause the distal end sections to taper into an electrode foil stack, and then translating the clamp a predetermined distance toward the fixture to displace the distal end sections by the predetermined distance. The method also includes trimming the distal end sections using a trim tool, positioning a sonotrode and an anvil adjacent opposite surfaces of the stack, and ultrasonically welding the stack to a conductive lead tab using the sonotrode to thereby form a welded joint within the battery cell. The sonotrode may be multi-sided with different knurl patterns for performing different welding processes.

Abstract: The subject technology is related to autonomous vehicles (AV) and, in particular, to an environmental and electromagnetic seal for autonomous vehicle control systems. The AV includes an autonomous driver system computer (ADSC) fixed to an interior surface of the AV and configured to control the electronic drivetrain, the ADSC including at least one port for connecting with an AV and an elastic conductive cover for selectively sealing the at least port one. The elastic conductive cover comprises a hooking member with an opening that is rotatably connected to the ADSC, cannot be independently removed from the ADSC, and includes an inner surface having at least one extended member with a sealing member that is configured to seal a port of the at least one port.
Abstract: An energy attenuating vehicle display mount includes an instrument panel support mounted to a dashboard, an instrument panel support bracket coupled to the instrument panel support, a display mount coupled to the instrument panel support bracket, and an energy attenuating fastener connecting the display mount to the instrument panel support bracket. The energy attenuating fastener accommodates movement of the display mount relative to the instrument panel support bracket.
Abstract: A method is described and includes subsequent to an autonomous vehicle becoming immobilized, initiating a local assistance request; subsequent to the initiating, receiving local assistance input from a passenger of the autonomous vehicle; and using the local assistance input to determine an action to be taken by the autonomous vehicle to mobilize the autonomous vehicle.

Abstract: A vehicle, arc fault protection device of the vehicle and a method for mitigating an arc fault in an electrical system of the vehicle. The arc fault protection device includes a sensor, a switch, and a processor. The sensor is used for measuring a current in an electrical system. The processor is configured to determine a precursor phase of an arc fault from the current, wherein the precursor phase indicates an onset of an arc flash phase of the arc fault. The processor opens the switch to mitigate the arc fault during the arc flash phase.

Abstract: A system for managing communication between a vehicle and a broker module includes a telematics unit connected to the vehicle. The telematics unit is configured to carry out wireless data communications according to a publish-subscribe messaging protocol. A command unit is in communication with the telematics unit, the command unit having a processor and tangible, non-transitory memory on which instructions are recorded. The telematics unit is configured to establish a network connection with the broker module. The command unit is adapted to create a dynamic retry delay process for the network connection by varying a connection retry delay time based on a plurality of failure categories and an operation mode of the vehicle. The plurality of failure categories each corresponds to a respective failure in the network connection.
