Abstract: A system for directional communication is disclosed. The system may include an ultrasonic beamforming device, sensors, and a processor. The ultrasonic beamforming device may be configured to transmit an ultrasonic carrier wave. The processor may be configured to obtain inputs from a detection unit located in a geographical area and detect an object presence in the geographical area based on the inputs. The processor may be further configured to determine an object location in the geographical area based on the inputs. The processor may additionally determine an optimum sound frequency to modulate the ultrasonic carrier wave. Furthermore, the processor may cause the ultrasonic beamforming device to transmit the ultrasonic carrier wave modulated at the optimum sound frequency towards the object location.

Abstract: A system to control a trailer is disclosed. The trailer may be attached to a towing vehicle. The system may include a transceiver configured to receive road information, vehicle information and trailer information. The system may further include a processor configured to determine that a predefined condition may be met based on the received road information, the vehicle information, and the trailer information. The processor may be further configured to transmit a command signal to a trailer wheel control unit to activate a trailer wheel drive motor responsive to a determination that the predefined condition is met. The trailer wheel drive motor may be located in a trailer.

Abstract: A vehicle puddle lamp assembly including a housing, a lens coupled to the housing, and a printed circuit board mounted to the housing. At least one near-infrared light source to emit near-infrared light through the lens is coupled to the printed circuit board. A palm image sensor is also coupled to the printed circuit board. The palm image sensor is configured to detect a palm vein pattern illuminated by the near-infrared light and reflected from a user's palm through the lens.
