Abstract

The present invention relates to a method and a system for monitoring on-line the condition of a subject, wherein a measuring system is used for carrying out the measurements on the subject. This measuring system is provided with a transmitter for transmitting the signals to a monitoring unit, where the signals are stored. The monitoring unit compares on-line the signals with previous signals and based on the comparison generates a subject related condition signal.

a second transceiver unit for bidirectional data communication with the at least one sensor, and

a processing means and storage means for electronically storing the signal and a reference signal and storage means having stored therein a computer program, the processing unit being adapted, in response to commands of the computer program, to on-line compare the signal with the reference signal and based on the comparison to generate a subject related condition signal, and

a stationary monitoring means (350) with processing means and storage means for electronically storing signal information from the user terminal and a reference signal and storage means having stored therein a computer program, the processing unit being adapted, in response to commands of the computer. program, to on-line compare the signal information with the reference signal and based on the comparison to generate a subject related condition signal.

2. A system according to claim 1, wherein the mobile user terminal comprises an input means with a user interface.

3. A system according to claim 1 or 2, wherein the mobile user terminal comprises an output means for on-line graphically displaying the received data from the at least one sensor.

4. A system according to any of the preceding claims, wherein the mobile user terminal comprises at least one transceiver for transmitting the signal representing the identity and the measured data to the monitoring unit.

5. A system according to any of the preceding claims, wherein the mobile user terminal is provided with a wireless connection to at least one sensor and a wireless connection to at least one stationary monitoring unit.

6. A system according to any of the preceding claims, wherein the at least one sensor unit is provided with an indication means for signalling (could be alarming) in case it has lost connection to the mobile user terminal.

7. A system according to any of the preceding claims, wherein the mobile user terminal is provided with an indication means for signalling (could be alarming) in case it has lost connection to either the at least one sensor unit or in case it has lost connection to the stationary monitoring unit.

8. A system according to any of the preceding claims, wherein the stationary monitoring unit is provided with an indication means for signalling (could be alarming) in case it has lost connection to the mobile user terminal.

9. A system according to any of the preceding claims, further comprising means for locating the mobile user terminal through the mobile communication network based on information from the telecommunication central or network provider.

10. A system according to any of the preceding claims, wherein the mobile user terminal acts as a master unit for the at least one sensor and/or the mobile user terminal takes control of at least one sensor through bidirectional data communication link.

11. A system according to any of the preceding claims, wherein the mobile user terminal is used for defining the activity of the at least one sensor.

12. A system according to any of the preceding claims, further comprising means for locating the mobile user terminal by means of using a Global Positioning System (GPS).

13. A system according to any of the preceding claims, wherein the mobile user terminal is a mobile phone (UMTS, GPRS, EDGE) and/or a PC computer and/or PDA/Palmtop and/or Laptop.

14. A system according to any of the preceding claims, wherein the mobile user terminal comprises a rechargeable battery.

15. A system according to any of the preceding claims, wherein the at least one sensor is based on an electrode system.

16. A system according to any of the preceding claims, wherein the electrode system is reusable.

17. A system according to any of the preceding claims, wherein the sensor unit is wirelessly connected to subset of at least sensor.

18. A system according to any of the preceding claims, wherein the at least one sensor transceiver has a transmission power in the range of 0.8-1.3 mW such as in the range of 1-1.1 mW.
