  • Activation interface for generic automatic engine starting devices
    Patent number: 6390047
    Abstract: A system to interface the activation of an automatic engine starting device with a temperature threshold switch. The invention integrates a temperature threshold signal input, a run mode signal input, and an ignition key-on signal input operatively connected to a mode control switch circuit whereby the mode control switch circuit generates a mode control output signal if the threshold signal is present, and the run mode signal and the ignition key-on signal are not present. The invention incorporates a pulse switch circuit operatively connected to said timer controlled output signal whereby a one-shot pulse switch output signal is generated upon reception of a timer controlled output signal. The present invention can be used as a temperature safety system for a pet inside the cabin of a vehicle in hot weather conditions, or as a block heater to prevent the engine block of a vehicle from freezing in cold weather conditions.
