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.
Claims25
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;
- wherein
- said 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.
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.
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.
