Abstract
A system and device for insuring the integrity of an automatic garage door has a sensor to determine the status of the door with respect to a predetermined position and a programable actuator which provides a positive signal for automatically activating a warning or alert system when the door is in predetermined position when the programmable actuator is activated and the sensor indicates that the door is at other than the predetermined position. Preferably the programmable actuator is a timer and the predetermined position is closed. The timer can be remotely programmable. The actuator can also be triggered by a sensor of an event such as darkness. Remote means are provided for manually activating the door to return to the desired position by an RF frequency transmitter.
Claims29
A security system for determining if an automated door is in a pre-determined position, the security system comprising:
- a sensor configured to determine a position of the automated door;
- a signal generator in communication with said sensor and configured to provide a signal indicative of the position of the automated door;
- a warning device configured to receive the signal;
- and
- processing circuitry associated with the warning device for comparing the pre-determined position of the automated door with the position of the automated door as indicated by the signal;
- wherein said warning device provides a warning only when the position of the automated door differs from the pre-determined position of the automated door as determined by the processing circuitry.
A security system for an automated door, the security system comprising:
- means for sensing a position of said door;
- means, in communication with said sensing means, for generating a signal indicative of said position of said door;
- means for comparing said position of said door as indicated by the signal to a pre-determined position of said door to determine if said door is in a desired position;
- and
- means for producing a warning only when said position of said door differs from said desired position.
A method of improving the security of an automated door, the method comprising:
- selecting a pre-determined position of the automated door;
- sensing a position of the automated door;
- transmitting a signal indicative of the position of the automated door to a warning device;
- comparing the position of the automated door as indicated by the signal with the pre-determined position of the automated door using processing circuitry associated with the warning device;
- and
- generating a warning only when the position of the automated door differs from the pre-determined position of the automated door as determined by the processing circuitry.
