  • Publication number: 20240157791
    Abstract: A method of controlling a color display screen aboard a motor vehicle includes performing, via a host computer, a color calibration test of a user of the motor vehicle in which the user is subjected to a calibrated set of color-coded test information. The method includes receiving a color perception response of the user to the calibrated set of color-coded test information via the host computer. Additionally, the method includes mapping a reduced visual gamut of the user via the host computer using the color perception response, and then commanding adjustment of user-specific color settings of the motor vehicle using the reduced visual gamut to thereby accommodate a color perception deficiency of the user.

  • 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: 11982660
    Abstract: A quality control system analyzes the quality of a battery cell, with the battery cell defining a gas pouch configured to be filled with a gas. The quality control system includes a computational system including a processor and a memory, a manifold defining a passageway extending between an inlet port for receiving the gas and an outlet port, and at least one sensor in electronic communication with the computational system. The sensor is arranged to measure a physical property of the gas and transmit a signal to the computational system corresponding to the physical property of the gas. The computational system analyzes the physical property of the gas, accesses a threshold value corresponding to the physical property, compares the physical property to the threshold value, and assess a quality score for the battery cell. A corresponding method analyzes the quality of the battery cell with the quality control system.

  • Patent number: 11981280
    Abstract: A vehicle seat restraint system includes a vehicle seat of a vehicle. The vehicle seat includes a leg-rest supporting lower legs and feet of an occupant of the vehicle seat. An in-vehicle occupant detection system identifies positions of the lower legs and the feet of the occupant. A restraint actuator is connected to the vehicle seat. A safety restraint element is extended by actuation of the restraint actuator from a stowed position proximate to the leg-rest into an engaged position wherein the safety restraint element contacts and restrains the lower legs and the feet of the occupant against the leg-rest, mitigating against occupant knee hyperextension due to leg straightening at an occupant knee joint.
