  • Patent number: 11981208
    Abstract: A control system for a vehicle comprises a controller comprising a processor and a non-transitory computer-readable medium including instructions. The system comprises a transformable knob manipulated between first and second states. The knob comprises a body having a periphery wall arranged to flex between first and second configurations with the first and second states, respectively. The system comprises an output device arranged to change between first and second settings. Manipulation of the transformable knob from the first state to the second state transmits an input signal to the controller and facilitates flexing of the periphery wall from the first configuration to the second configuration. The controller receives the input signal, and the processor compares the input signal to the instructions in the non-transitory computer-readable medium and transmit an output signal to the output device to change the output device from the first setting to the second setting.

  • Patent number: 11981345
    Abstract: An autonomous vehicle (AV) implements a notification system that provides notifications to user devices in nearby vehicles to alert drivers of the nearby vehicles of the AV's planned behavior. The notifications are delivered wirelessly and output by the user device to the drivers. The planned behaviors of the AV may not be conveyed by existing mechanisms, such as turning signals or hazard lights. The AV or the receiving user device may determine when an AV's planned behavior may impact a particular driver, and provide relevant notifications to the driver.

  • Patent number: 11978880
    Abstract: A method for forming a layered anode material includes contacting a precursor material and a first electrolyte. The precursor material is a layered ionic compound represented by MX2, where M is one of calcium and magnesium and X is one of silicon, germanium, and boron. The method further includes applying a first bias and/or current as the precursor material contacts the first electrolyte to remove cations from the precursor material to create a two-dimensional structure that defines the layered anode material. In certain variations, the method further includes contacting the two-dimensional structure and a second electrolyte and applying a second bias and/or current as the two-dimensional structure contacts the second electrolyte so as to cause lithium ions to move into interlayer spaces or voids created in the two-dimensional structure by the removal of the cations thereby forming the layered anode material.

  • Patent number: 11975714
    Abstract: Presented are embedded control systems with logic for computation and data sharing, methods for making/using such systems, and vehicles with distributed sensors and embedded processing hardware for provisioning automated driving functionality. A method for operating embedded controllers connected with distributed sensors includes receiving a first data stream from a first sensor via a first embedded controller, and storing the first data stream with a first timestamp and data lifespan via a shared data buffer in a memory device. A second data stream is received from a second sensor via a second embedded controller. A timing impact of the second data stream is calculated based on the corresponding timestamp and data lifespan. Upon determining that the timing impact does not violate a timing constraint, the first data stream is purged from memory and the second data stream is stored with a second timestamp and data lifespan in the memory device.
