LOW POWER MOVEMENT SENSOR
First Claim
1. A detection system for monitoring and recording distance to at least one target, said detection system comprising at least one module comprising:
- a power source;
a trigger unit configured to detect the presence of said target and operable to generate an enablement signal upon detection of said target;
a data gathering unit comprising at least one measurement sensor operable to obtain at least one measured parameter and to record said at least one measured parameter in a memory; and
a retrieval mechanism for providing access to records stored in said memory;
whereinsaid trigger unit comprises a passive detector and said measurement sensor is operable to draw power from said power source only when the enablement signal is received from said trigger unit.

Abstract
A detection system for monitoring and recording distance to at least one target. The detection system may comprise at least one module comprising: a power source; a trigger unit configured to detect the presence of the target; an enablement mechanism in communication with the trigger unit and operable to generate an enablement signal upon detection of the target; a data gathering unit comprising at least one measurement sensor operable to obtain at least one measured parameter and to record the at least one measured parameter in a memory; and a retrieval mechanism for providing access to records stored in the memory.

17. A method for monitoring at least one target, said method comprising the steps of:
-
providing at least one module comprising a trigger sensor and a measurement sensor, detecting the presence of said at least one target with said trigger sensor; initiating an enablement signal upon the detecting the presence of said target; said measurement sensor obtaining a target distance upon receiving said enablement signal, said target distance characterized as the distance between said measurement sensor and said target; and recording said target distance in a memory. - View Dependent Claims (18, 19, 20, 21, 22)

23. A method for monitoring to at least one target, said method comprising the steps of:
-
providing a plurality of modules comprising a trigger sensor, a measurement sensor and a transmitter, detecting the presence of said at least one target with the trigger sensor of at least one of said plurality of modules; initiating an enablement signal upon the detecting the presence of said target; a measurement sensor obtaining a target distance upon receiving said enablement signal, said target distance characterized as the distance between said measurement sensor and said target; and recording said target distance in a memory. - View Dependent Claims (24, 25)
