TAGGING SYSTEM USING MOTION DETECTOR |
摘要 |
The present invention relates generally to a tag monitoring system network (16) used for tracking object movement. The tags (10) utilized in the system incorporate a motion sensor (18) which detects object movement and includes a signal generation circuit adapted to generate a signal when motion is detected. A microcontroller (20) is provided which is in electrical communication with the motion sensor (18) and includes a transmitter activation circuit wherein said microcontroller (20) includes a preprogrammed transmitter sequence which is activated by receipt of a signal from the motion sensor (18). A radio transmitter (12) is also provided on the tag (10) which is in electrical communication with the microcontroller (20), and generates radio signals at the direction of the microcontroller (20).
