Abstract

A movement sensor for establishing a movement profile of a living being, in particular a human, is characterized in that the movement sensor has an arrangement for automatically changing between various operating modes.

Claims

1. A movement sensor system for establishing a movement profile of a human, comprising:

a movement sensor unit;

an at least one additional sensor unit to detect different environmental conditions; and

a control unit for automatically changing between various operating modes of the movement sensor unit as a function of the different environmental conditions provided by the at least one additional sensor unit, in order to determine the movement profile.

2. The system as recited in claim 1, wherein the movement profile represents analysis of a physical activity including at least one of sitting, lying down, standing, walking, cycling, swimming, and running.

3. The system as recited in claim 1, wherein the various operating modes each implements a different set of algorithms.

4. The system as recited in claim 1, wherein the at least one additional sensor unit comprises a device measuring a resistance between a first contact and a second contact, wherein the resistance is used to determine whether the movement sensor system is in water.

5. The system as recited in claim 1, wherein the at least one additional sensor unit comprises a capacitive moisture sensor.

6. The movement sensor system as recited in claim 1 wherein the automatically changing between various operating modes of the movement sensor unit is provided as a function of an identifier of at least one fastening element which is analyzed by the movement sensor, the various operating modes being based on different movement patterns at different positions of the movement sensor on a body of the human.

7. The system as recited in claim 1, wherein the various operating modes include a mode for movements in air and a mode for movements in water.

8. The system as recited in claim 1, wherein the environmental conditions include at least one of moisture, temperature, pressure, and resistance.

9. The movement sensor system as recited in claim 1, wherein the movement sensor unit is provided for defined positioning on the body of the living being.

10. A method for establishing a movement profile of a human, comprising:

detecting by a sensor unit at least one of a plurality of different environmental conditions; and

determining the movement profile by automatically changing between various operating modes of a movement sensor unit as a function of at least one of the detected different environmental conditions.

11. The method as recited in claim 10, wherein the automatically changing between various operating modes of the movement sensor takes place as a function of a position of the movement sensor on a body of the human, the position of the movement sensor on the body of the human being determined using an identifier of at least one fastening element, which is analyzed by the movement sensor.
