Windshield Wiper System
US Patent:
5355061, Oct 11, 1994
Filed:
Jan 24, 1992
Appl. No.:
7/825628
Inventors:
Michael Forhan - Urbana OH
Assignee:
Grimes Aerospace Company - Columbus OH
International Classification:
B60S 108
US Classification:
318443
Abstract:
The present invention is an improved windshield wiper assembly. The assembly includes a wiper blade which undergoes oscillatory rotary motion and is swept back and forth between two extreme locations across a windshield to remove rain and other precipitation from the windshield. A brushless DC motor has its output shaft connected to the wiper assembly. The foregoing results in rotary oscillation of the blade and permits the elimination of the four-bar mechanism which is typical of prior art wiper assemblies. The rotary motion of the blade in either direction is decelerated when the blade reaches a preselected position between two extreme locations.

International Classification:
F16D 3702, H02K 4910
US Classification:
318370
Abstract:
A magnet brake is disclosed. The magnet brake may consist of a stationary magnet assembly and a rotating magnet assembly. The opposing poles on the magnet assemblies have a mutual attraction that biases the assemblies into alignment with each other. The magnet brake may also be combined with Hall-effect switches to provide position and direction detection.
