Abstract

An automated, real-time, reprogrammable monitoring and control system for portable, remote sensors and subjects includes one or more portable monitoring units, each of the portable monitoring units having a sensor, a location-determining device, and a sensor interface unit. Each sensor interface unit is separately configured to monitor its sensor and to transmit that sensor'"'"'s data, via a digital wireless communications network, to a central monitoring device. The portable unit is carried or worn by a person or animal, or affixed to an inanimate subject.

Claims

at least one automatic sensor associated with and monitoring the condition of the human subject; and

a portable monitoring unit capable of communicating with a central monitoring device, the portable monitoring unit comprising;

a programmable microprocessor in communication with the at least one automatic sensor, the microprocessor being responsive to the occurrence of any of a set of activating parameters, the activating parameters selected from the group consisting of a preselected state of the at least one automatic sensor and a request signal from an external source,

a first transceiver in communication with the microprocessor, for communicating signals between the microprocessor and the central monitoring device, and

a power supply connected to provide power to at least one of the microprocessor and the first transceiver.

2. The apparatus of claim 1, wherein at least one automatic sensor comprises a sensor selected from the group consisting of a biological condition sensor, an accelerometer, and an audio sensor.

3. The apparatus of claim 1, wherein the portable monitoring unit further comprises:

a portable-unit location-determining device.

4. The apparatus of claim 1, wherein the programmable microprocessor has an active state and an inactive state, the microprocessor being operable to change from the inactive state to the active state responsive to the occurrence of any of the activating parameters.

5. The apparatus of claim 1, further comprising:

at least one monitoring device in communication with the central monitoring device.

6. The apparatus of claim 1, wherein the portable monitoring unit comprises

an audio/visual indicator in communication with the microprocessor.

7. The apparatus of claim 1, wherein the portable monitoring unit comprises

a subject status signal input device activatable by the human subject and in communication with the microprocessor.

8. The apparatus of claim 1, further comprising a portable central monitoring device.

9. The apparatus of claim 1, further comprising:

at least one additional portable monitoring unit having the same structure as the portable monitoring unit.

10. The apparatus of claim 1, wherein the request signal from the external source comprises a periodic status query from the central monitoring device.

11. The apparatus of claim 1, wherein the preselected state of the at least one automatic sensor comprises a preselected sensor reading from a medical device.

12. The apparatus of claim 1, wherein the microprocessor is responsive to receive a reprogrammed activating parameter.

13. The apparatus of claim 1, wherein the microprocessor is responsive to transmit all data received once activated.

14. The apparatus of claim 1, wherein the microprocessor is responsive to transmit data meeting a certain predefined criteria.

15. A method for remotely monitoring the status of a human subject, the method comprising:

providing the human subject with at least one automatic sensor selected from the group consisting of a biological condition sensor, a medical device, and an audio sensor;

providing the human subject with a portable monitoring unit comprising;
