Abstract
A tag and method for use with a monitoring system, the tag having straps for attaching the tag to the limb of a person, a motion sensor for determining the motion of the person wearing the tag and a second sensor for detecting that the tag was tampered with, the information received from the tag can be identified as tamper alarms.
Claims20
A tag having enhanced tamper detection capabilities for use with a monitoring system, the tag having an identification code, the tag is placed within a housing, the tag comprising:
- a power supply,
- a central processing unit,
- at least one strap for attaching the tag to the limb of a person,
- a motion sensor for determining pattern of the motion of the person wearing the tag wherein the pattern of motion so determined being compared with a stored pattern of motion for determining whether the tag was tampered with;
- a second sensor for detecting whether the tag was tampered with, and
- a transmitter for transmitting a tamper signal to a remote monitoring unit.
A method for monitoring and detecting a monitored person's behavior for distinguishing between different monitored persons, the method comprising the steps of:
- examining signals received from at least one motion sensor located within a tag strapped to the limb of a monitored person at predetermined intervals;
- processing the signals to determine a pattern of motion related behavior associated with the monitored person;
- storing the pattern of motion related behavior associated with the monitored person;
- and
- comparing the pattern of motion related behavior associated with the monitored person with a motion related behavior signal pattern.
