Abstract: Light bar assemblies configured to be mounted to a rim of a steering wheel of a vehicle are disclosed. The light bar assemblies can include components of a driver monitoring system. The light bar assembly includes two shells defining or surrounding the rim and a wrapping surrounding the two shells. A portion of the wrapping is tucked into a slot disposed between the two shells forming a slit. A lens comprises a visible light transmissive portion and an IR light transmissive portion.

Abstract: Wraps for a steering wheel and methods of wrapping a steering wheel with an integrated light bar assembly are disclosed. The light bar assembly is configured to be mounted to a rim of a steering wheel of a vehicle. The light bar assemblies can include components of a driver monitoring system. The light bar assembly includes two shells defining or surrounding the rim and a wrapping surrounding the two shells. A portion of the wrapping is tucked into a slot disposed between the two shells forming a slit. A lens is disposed within the slit and pinched by the wrapping to prevent leakage of light around the lens.

Abstract: Light bar assemblies configured to be mounted at a rim of a steering wheel of a vehicle are disclosed. The light bar assemblies can include components of a driver monitoring system. The light bar assembly includes a PCB bar having a plurality of visible and infrared LEDs and a LED driver. The PCB bar is coupled to a support plate of an outer shell surrounding the PCB bar. The support plate transfers heat generated by the LEDs and LED driver away from the PCB bar.

Abstract: A circuit arrangement having a master microcontroller operably connected to a sensor for detecting a parameter. A power communications line is connected between the power source, master microcontroller, and sensor, wherein the power communications line carries power to the sensor as well as communication signals between the sensor and the master microcontroller. An embodiment of an automotive ultrasonic sensor system for object detection is disclosed, where the master microcontroller is connected to a number of external ultrasonic sensors via the circuit arrangement. The circuit arrangement is also advantageous in enabling a separate wire harnesses to be configured for the external ultrasonic sensors that operates at logic power levels (e.g., 5V) rather than the vehicular accessory drive voltage (typically 12V) present in the vehicular wire harness that interfaces the master microcontroller with other controllers in the vehicle.
