International ClassB60S 001/54AbstractA remotely-operated vehicle windshield defrost system having the capability of being initiated before the driver enters the vehicle, e.g. while he is having breakfast before leaving for work. The windshield can thus be essentially frost-free at the moment the vehicle enters traffic; there is no delay, as with conventional defrost systems which depend on the engine warming up before the defrost action can begin.Field of SearchWindshield or window | |
