  • Patent number: 10766463
    Abstract: A system includes a dome, a wiper assembly, a position sensor and a control device. The wiper assembly includes a wiper blade configured to rotate around the dome. The position sensor may be configured to send a signal to a control device when a wiper blade passes the position sensor. The control device may include one or more processors configured to receive the signal from the position sensor and determine a location of the wiper blade relative to the dome based on the received signal.

  • Publication number: 20200166589
    Abstract: An integrated hybrid rotary assembly is configured to provide power, torque and bi-directional communication to a rotatable sensor, such as a lidar, radar or optical sensor. A common ferrite core is shared by a motor, rotary transformer and radio frequency communication link. This hybrid configuration reduces cost, simplifies the manufacturing process, and can improve system reliability by employing a minimum number of parts. The assembly can be integrated with the sensor unit, which may be used in vehicles and other systems.

  • Patent number: 9731688
    Abstract: A wiper system for clearing a surface of a dome includes a plurality of wiper blades that are configured to move around a circumference of the dome. Rotation of the wiper blades in a first direction around the circumference of the dome deploys the wiper blades into an upright position and rotation of the wiper blades in a second direction opposite the first direction stows the wiper blades into a collapsed position.
