MONITORING CHANGES IN BEHAVIOR OF A HUMAN SUBJECT
First Claim
1. A method of monitoring behavior of a subject comprising:
- monitoring the movements of the subject within a space using one or more sensor each comprising a two dimensional array of thermal detector elements;
processing signals from the at least one sensor to determine current values for one or more parameters associated with one or more patterns of behavior of the subject;
establishing one or more models of a pattern of subject behavior for the subject or the space being monitored; and
using the current values and the established one or more model of a pattern of behavior to identify aberrations from an established model for the subject or the space.

Abstract
A system and method of identifying changes in behavior of a human subject comprises monitoring the movements of the subject within a space using one or more sensors, processing signals from the sensor(s) to determine values for one or more parameters associated with one or more patterns of behavior of the subject, using values for the one or more parameters accumulated over a period of time to establish one or more models of a typical pattern of behavior for the subject, monitoring the ongoing behavior of the subject to obtain current values for one or more of the parameters; and using the current values and the model(s) of a typical pattern of behavior to identify atypical behavior of the subject.
An alert may be generated if the current value of one or more of the parameters is outside the acceptable limit(s). Advantageously low resolution thermal imagers are used so as to minimise intrusiveness and invasion of privacy.

14. A system for identifying changes in behavior of a human subject comprising:
-
at least one sensor comprising a two dimensional array of thermal detector elements, wherein the at least one sensor is configured to monitor the movements of the subject within a space; and one or more processors configured to; process signals from the at least one sensor to determine current values for one or more parameters associated with one or more patterns of behavior of the subject; establish one or more models of a pattern of subject behavior for the subject or the space being monitored; and use the current values and the established one or more model of a pattern of behavior to identify aberrations from an established model for the subject or the space.

-
process signals from the at least one sensor to determine current values for one or more parameters associated with one or more patterns of behavior of the subject; establish one or more models of a pattern of subject behavior for the subject or the space being monitored; and use the current values and the established one or more model of a pattern of behavior to identify aberrations from an established model for the subject or the space.

16. A method of monitoring behavior of a subject comprising:
