Moisture sensor for an automatic vehicle window wiper control
First Claim
1. In a moisture sensor for sensing ambient moisture in the vicinity of a vehicle window having a window wiper, said sensor comprising, in combination:
- (a) a plurality of spaced apart conductive strips having an exposed surface, the electrical resistance between adjacent strips being dependent on the ambient moisture; and
(b) means for repetitively removing the moisture from said exposed surface and in the region between said strips;
the improvement wherein said plurality of conductive strips is located at a position other than in the area of sweep of said window wiper on said window and at least one of said removing means and said plurality of conductive strips is coupled to said window wiper;
whereby said at least one of said removing means and said plurality of conductive strips is actuated by said window wiper and operates in synchronism therewith.

Abstract
A moisture sensor for sensing ambient moisture in the vicinity of a window having a window wiper. The sensor comprises a plurality of spaced apart conductive strips having an exposed surface. The electrical resistance between adjacent strips is dependent on the ambient moisture. The sensor also includes means for repetitively removing the moisture from the exposed surface and in the region between the strips. The conductive strips are located at a position other than in the area of sweep of the window wiper on the window and at least one of the removing means and the plurality of conductive strips is coupled to the window wiper, whereby the at least one of the removing means and the plurality of conductive strips is actuated by the window wiper and operates in synchronism therewith.
