Abstract:
A door, or window detector incorporates a magnet and a magnetometer. Dual loop processing can be provided for real-time signals from the magnetometer, as the magnet moves relative to it, to determine when at least one of small gap or large gap indicating alarms should be issued. Security can be substantially increased by randomizing the orientation of the magnet.
