Abstract

A system in which two or more different measurement processing procedures are included in a personal unit attached to the user. These procedures are applicable for computing measurement data from a single signal generated by a sensory system of the personal unit. The measurement processing procedure to be presently applied is selected according to control information received from a separate monitoring unit. The present invention provides a simple way to provide more versatile measurement results and make them accessible to a variety of different user applications.

Claims

1. A system, comprising a personal unit and a monitoring unit interconnected for communication,

wherein the personal unit comprises:

a sensory system and a device for detachably attaching the sensory system to the outer surface of a skin of a user, the sensory system being configured to generate a first signal representing electrical changes on the outer surface of the skin of the user;

a measurement processing module connected to the sensory system and configured to process the first signal into measurement data, the measurement processing module comprising a group of at least two different measurement processing procedures for computing the measurement data from the first signal, and

wherein the monitoring unit comprises;

a state module configured to compute from the received measurement data one or more output values representing a physiological state of the user, the state module comprising two or more different computing methods for computing the one or more output values from the received measurement data, each of the computing methods corresponding to one measurement processing procedure of the personal unit; and

a control module configured to provide to the personal unit control data for selecting a measurement processing procedure, and to activate a corresponding computing method in the state module, and wherein the measurement processing module comprises a selection module, configured to activate one measurement processing procedure from the group of at least two different measurement processing procedures according to the control data received from the monitoring unit.

2. An apparatus, comprising:

a sensory system and a device for detachably attaching the sensory system to the outer surface of a skin of a user, the sensory system being configured to generate a first signal representing electrical changes on the outer surface of the skin of the user;

a measurement processing module connected to the sensory system and configured to process the first signal into measurement data computed with a predetermined measurement processing procedure from the first signal; and

a first communication module configured to send the measurement data to a monitoring unit, wherein

the measurement processing module comprises a group of at least two different measurement processing procedures for computing the measurement data from the first signal, and the measurement processing module comprises a selection module, responsive to control data received from the monitoring unit, and configured to activate one procedure from the group of measurement processing procedures according to the control data received from the monitoring unit.

3. An apparatus according to claim 2, wherein the sensory system comprises a combination of two or more electrodes that are responsive to electrical potentials generated on the skin of a user when the heart muscle of the user depolarizes during heartbeats, the two or more electrodes being combined to generate an analog first signal.

4. An apparatus according to claim 3, comprising a measurement processing procedure for outputting digital values modeling present ECG of the user and a different measurement processing procedure for outputting time interval values between successive characteristic points in the first signal.

5. An apparatus according to claim 4, comprising a third measurement processing procedure for outputting heart rate values indicating the number of heartbeats per unit of time.

6. A method, comprising:

selecting from a group of two or more different measurement processing procedures a measurement processing procedure to be used in computing measurement data from one sensor signal in a personal unit;

generating control data indicating the selected measurement processing procedure;

sending the control data to the personal unit;

activating from a group of two or more different computing methods a computing method corresponding to the selected measurement processing procedure; and

computing with the activated computing method from the measurement data one or more output values representing a physiological state of the user.

7. A method of claim 6, wherein the steps of the method are performed in a user node or a network node of a monitoring system.

8. A method of claim 6, wherein all steps of the method are performed in the user node of the monitoring system.

9. A method of claim 6, wherein all steps of the method are performed in the network node of the monitoring system.

10. A monitoring apparatus, configured to execute the method of claim 6.

11. A computer program product embodied on a non-transitory computer-readable medium, said computer readable medium including instructions for executing, when run on a computer, the method of claim 6.
