Abstract
Abstract A windshield wiper control system has a motor connected to a shaft for driving a wiper in a normal and a reverse directions. A wiper position detector includes a plurality of detector levers for providing output detection signals indicative of the position of the wiper. A storage device stores combinations of the output detection signals in a time-sequential order. A data generation device arranges the stored output detection signals from the detector, in predetermined time-sequential combinations, and prepares detection data therefrom. An indexing device compares the detection data prepared by the data generation device with corresponding combinations of stored output detection signals, and indexes the relative positions of the wiper resulting from such comparison.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
A wiper control system for controlling the movement of a wiper, comprising: (a) a motor having an output shaft selectively drivable in one of a normal and reverse direction, for driving the wiper; (b) a wiper position detector, including a plurality of detector contacts, for providing output detection signals indicative of the position of the wiper; (c) storage means for inputting said output detection signals and storing combinations of said output detection signals in a time-sequential order; (d) data generation means for generating and storing basic data formed of predetermined time-sequential combinations of said output detection signals to be detected; and (e) indexing means for comparing said combinations of said output detection signals stored in said storage means with combinations in said basic data which correspond to said combinations of said output detection signals, and for indexing the relative positions of the wiper resulting from the comparison.
Claim 2
Dependent Claim
147 words
A wiper control system for controlling the movement of a wiper, comprising: (a) a motor having an output shaft selectively drivable in one of a normal and reverse direction, for driving the wiper; (b) a wiper position detector, including a plurality of detector contacts, for providing output detection signals indicative of the position of the wiper; (c) storage means for inputting said output detection signals and storing combinations of said output detection signals in a time-sequential order; (d) data generation means for generating and storing basic data formed of predetermined time-sequential combinations of said output detection signals to be detected; and (e) indexing means for comparing said combinations of said output detection signals stored in said storage means with combinations in said basic data which correspond to said combinations of said output detection signals, and for indexing the relative positions of the wiper resulting from the comparison.
Claim 3
Dependent Claim
