ABSTRACT:
A machine to turn on the occupancy sensor(s) of a motor vehicle using a temperature sensing element. The temperature element senses a dangerously high temperature in the passenger compartment of a motor vehicle and energizes the occupancy sensors. The occupancy sensors energize for a time period sufficient to determine the presence or absence of an occupant. If no occupant is detected, the occupancy sensors de-energize after a set period of time. If an occupant is detected, an audible alarm is enabled to draw attention to the motor vehicle. Once the alarm is active, a key must be used to reset it. If no occupant is detected each operation of a door switch will cause an additional sensing provided the temperature remains dangerously high. This logic is only energized or enabled when a passenger compartment is dangerously high.
