Child alert system for automobiles
First Claim
1. A method of warning of a person trapped in an automobile, said method comprising the steps of:
- detecting motion within the interior of the automobile;
determining an actual temperature within the interior of the automobile;
comparing the determined actual temperature to an extreme temperature; and
activating an alarm to produce an alarm signal if motion is detected within the interior of the automobile and the actual temperature is greater than the extreme temperature.

Abstract
The present invention, in one form, is an alarm system for detecting the presence of a person locked in a parked automobile. The alarm system includes a motion detector and a temperature detecting element coupled to a NOR gate. The motion detector transmits a low signal to the NOR gate once it detects motion within the interior of the automobile. The temperature detecting element transmits a low signal to the NOR gate if the temperature in the automobile exceeds a pre-determined extreme temperature. The NOR gate, upon receiving low signals from both the temperature detecting element and the motion detector, transmits an alarm signal.
