Abstract
A device for detecting a being left within a vehicle includes a sensor that detects when a being (e.g. a pet, a child, etc.) is within a vehicle and the operator of the vehicle has moved away from the vehicle by more than, for example five feet. Upon detection of such, the device emits a sound to notify others nearby of the being that was left within the vehicle. The sound is preferably different than a sound of a typical vehicle theft alarm system. In a preferred embodiment, determination that the operator has left the vehicle is by a loss of a signal from a personal transmitter that is attached to the operator's key ring or worn by the operator. After moving away from the vehicle by more than five feet, the signal from the personal transmitter decreases and initiates determination if a being remains within the vehicle.
