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.

9. A method of determining a position of a wiper blade as the wiper blade rotates around a base of a dome, the method comprising:
-
receiving, by one or more processors, a signal from a position sensor indicating detection of the wiper blade at a first position relative to the dome; accessing information, by the one or more processors, about a speed of the wiper blade as the wiper blade rotates around the base of the dome; and determining, by the one or more processors, a second position of the wiper blade relative to the dome based upon the speed. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of controlling movement of a wiper blade assembly configured to move 360 degrees about a dome surface, the wiper blade assembly including a wiper blade, the method comprising:
-
receiving, by one or more processors, a signal indicating that optical deterrents are present on the dome surface; in response to receiving the signal, causing, by the one or more processors, the wiper blade assembly to move in a first direction around the dome surface by rotating a bearing ring to which the wiper blade is attached in a first direction around the dome surface and thereby moving the wiper blade from a stowed condition to a deployed condition a wiper blade, wherein the bearing ring extends around the dome surface; and causing, by the one or more processors, the wiper blade assembly to move in a second direction around the dome surface by rotating the bearing ring in the second direction and thereby moving the wiper blade from the deployed condition to the stowed condition, and wherein the second direction is opposite of the first direction. - View Dependent Claims (17, 18, 19, 20)

21. A system of determining a position of a wiper blade as the wiper blade rotates around a base of a dome, the system comprising:
-
a position sensor; the dome; and one or more processors configured to; receive a signal from the position sensor indicating detection of the wiper blade at a first position relative to the dome; access information about a speed of the wiper blade as the wiper blade rotates around the base of the dome; and determine a second position of the wiper blade relative to the dome based upon the speed. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
