Abstract

A body-worn monitoring system for obtaining and evaluating data from a person includes at least one sensor carried by the person to be monitored, and an evaluation unit worn by the person to be monitored which is supplied from a signal from the sensor. The evaluation unit either independently, or in communication with a remote computer, evaluates the data and initiates the generation of a message which is communicated to the monitored person by the evaluation unit. If data which is typical of the daily behavior pattern of the person fails to arrive, the person can be reminded of the necessity of undertaking a particular activity.

Claims

1. A monitoring system for obtaining and evaluating data from a person, comprising:

a motion sensor adapted to be carried body-proximate by a person to be monitored, said person having a daily routine including a motion pattern, said sensor producing a sensor signal dependent on body motion comprising said motion pattern of said daily routine;

an evaluation unit adapted to be worn by said person to be monitored, said evaluation unit containing trainable means, supplied over time with said sensor signal, for learning said daily routine over time from said sensor signal and, after said daily routine has been sufficiently learned, for evaluating said signal to detect a motion of said person deviating from said motion pattern of said daily routine for identifying a non-routine condition of said person to be monitored dependent on said sensor signal; and

said evaluation unit further including means for, upon identification of said non-routine condition, communicating with said person to be monitored to transmit a message perceptible only to said person to be monitored to prompt said person to alter said non-routine condition.

2. A monitoring system as claimed in claim 1 wherein said sensor is contained in said evaluation unit.

3. A monitoring system as claimed in claim 1 wherein said sensor comprises means for supplying data to said evaluation unit identifying a position of said person.

4. A monitoring system as claimed in claim 1 further comprising temperature sensor means, adapted to be carried body-proximate by said person to be monitored, for generating a temperature signal identifying a temperature of an environment in which said person is disposed and for supplying said temperature signal to said evaluation unit, and wherein said trainable means comprises means for identifying a condition of said person to be monitored dependent on said signal from said motion sensor and said temperature signal.

5. A monitoring system as claimed in claim 4 wherein said trainable means comprises means for evaluating said sensor signal from said motion sensor and said temperature signal dependent on a time of day at which said sensor signal from said motion sensor and said temperature signal are produced.

6. A monitoring system as claimed in claim 1 wherein said trainable means comprises means for evaluating said sensor signal dependent on a time of day at which said sensor signal is produced.

7. A monitoring system as claimed in claim 1 wherein said evaluation unit includes transmitter means for wireless data transmission to a location remote from said evaluation unit.

8. A monitoring system as claimed in claim 7 further comprising receiver means for receiving said data from said transmitter means.

9. A monitoring system as claimed in claim 1 wherein said means for communicating comprises a tactile stimulator.

10. A monitoring system as claimed in claim 1 wherein said means for communicating comprises means for reproduction of spoken messages.

11. A monitoring system as claimed in claim 1 wherein said at least one sensor comprises a sensor attached to a body surface of said person.

12. A monitoring system as claimed in claim 1 wherein said evaluation unit comprises means for communicating information to a telephone network.

13. A monitoring system as claimed in claim 1 further comprising a stationary computer, remote from said evaluation unit, and wherein said evaluation unit comprises means for wirelessly communicating with said stationary computer.

14. A monitoring system as claimed in claim 1 further comprising a computer remote from said evaluation unit, means for supplying data from said evaluation unit to said computer, and means in said computer for communicating with said evaluation unit to initiate generation of a message communicated to said person by said evaluation unit.
