INTERMITTENT CONTROL DEVICE |
摘要 |
A control device for operating windshield wiper blades intermittently with a dwell period between wiping cycles. The length of time of the dwell periods is determined by a thermistor. The resistance of the thermistor is varied by the wiper motor current so that the length of time of the dwell periods is varied inversely with the moisture on the windshield.
