US Patent:

56025262, Feb 11, 1997

Filed:

Nov 21, 1994

Appl. No.:

8/342806

Inventors:

Robert M. Read - Vancouver WA

International Classification:

B60Q 100

US Classification:

340457

Abstract:

An open door warning system for a vehicle includes an open door detector mounted on the vehicle, which detects when the door is left open, and a light module mounted on a side of the vehicle and operatively coupled to the detector. The light module is preferably aligned with a driver side rear view mirror so that the driver can view the light module through the rear view mirror. The light module includes a light source which is driven by the detector to generate a flashing warning light when the door is left open. This warning light can be seen by the driver through the rear view mirror and thereby be warned of the open door situation. The detector includes a magnetically actuated switch controlled by a magnet attached to a top edge of the door. The switch is mounted on the vehicle to be juxtaposed to the magnet when the door is closed. The switch is coupled to a power module which includes a light driver circuit, a rechargeable battery pack, and a solar cell to keep the battery pack charged.

Abstract:

A temperature alarm system includes a temperature sensing module and an alarm circuit that are powered by a photocell and a battery that is charged by the photocell. The photocell normally provides enough power to operate the system and charge the battery. When the temperature sensing module senses a temperature that exceeds a predetermined alarm limit, it generates an alarm signal which activates an alarm circuit that generates a visual and/or audible alarm either immediately after the alarm signal is generated, or after the alarm signal has been generated for a period of time. The generation of the alarm signal and/or the alarm causes the system power consumption to increase, so the system begins to draw power from the battery. After the alarm condition is corrected, the system returns to normal power consumption, and the photocell provides enough power to operate the system and charge the battery.
