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.
Claims20
A system for controlling movement of a wiper blade assembly, the system comprising:
- a wiper blade assembly including at least one wiper blade and a pivoting connector;
- and
- one or more processors configured to:
- receive a signal indicating that optical deterrents are present on a surface of a dome;
- in response to receiving the signal, cause the wiper blade assembly to move in a first direction around the dome by rotating a ring in a first direction around the dome so as to cause an actuator to move the at least one wiper blade from a stowed condition to a deployed condition, wherein the ring extends around the dome;
- and
- cause the wiper blade assembly to move in a second direction around the dome by rotating the ring in the second direction so as to cause the actuator to move the at least one wiper blade from the deployed condition to the stowed condition,
- wherein the second direction is opposite of the first direction,
- wherein the pivoting connector includes a post portion and the ring includes a ramp, and
- wherein the post portion is configured to interact with the ramp to move the at least one wiper blade from the deployed condition to the stowed condition.
