Abstract

A device method and system are provided for measuring the body temperature in the area of the head. Reliable measured values are furnished even during movement and physical exercise. The device includes a head strap (1), whose strap elements (2, 3) are in contact at least partially as strap sections (7, 10) with the scalp of a user (4) of the headband and in which at least one of the strap sections (7) is designed for receiving a first temperature sensor (12) measuring the skin temperature.

Claims

1. A device for measuring a body temperature of a user, the device comprising:

a head strap with a first strap element having a strap section at least partially in contact with the scalp of a user and a second strap element with a strap section at least partially in contact with the scalp of a user; and

a temperature sensor for measuring the skin temperature, at least one of said first strap section and said second strap section receiving the temperature sensor.

2. A device in accordance with claim 1, wherein said temperature sensor is fastened in an area of the forehead of the user.

3. A device in accordance with claim 1, wherein said temperature sensor is fastened in the area of the top side of the head of the.

4. A device in accordance with claim 1, further comprising another temperature sensor for detecting the temperature of the close in space.

5. A device in accordance with claim 1, wherein the strap section receiving said temperature sensor is at least partially provided as a pressure-sensitive element.

6. A device in accordance with claim 1, further comprising a protective helmet wherein the strap sections are elements of a inner part of a protective helmet with a fixed outer shell.

7. A device in accordance with claim 6, wherein said inner part is a helmet inner shell.

8. A device in accordance with claim 4 further comprising a protective helmet wherein the strap sections are elements of a inner part of a protective helmet with a fixed outer shell wherein said additional temperature sensor is fastened in the area between the inner part and the inner wall of the outer shell.

9. A device in accordance with claim 4, wherein said temperature sensor and said additional temperature sensor are integrated in one assembly unit providing a double temperature sensor, in which the temperature sensors are arranged opposite and thermally insulated from one another.

10. A device in accordance with claim 4, further comprising an evaluating circuit and a receiving station, wherein said temperature sensor and said additional temperature sensor are connected to said evaluating circuit for transmitting measured temperature values to said receiving station.

11. A device in accordance with claim 10, further comprising a wireless transmission section provided between the evaluating circuit and the receiving station.

12. A device in accordance with claim 10, further comprising a contact switch actuating at least said evaluating circuit by which said evaluating circuit can be brought into an operating position when the head strap is put on.

19. A system in accordance with claim 4, wherein said first temperature sensor and said second temperature sensor are integrated in one assembly unit providing a double temperature sensor, in which the temperature sensors are arranged opposite and thermally insulated from one another.

20. A system in accordance with claim 10, further comprising a wireless transmission section provided between the evaluating circuit and the receiving station.

13. A method of monitoring a users body temperature, the method comprising:

providing a double temperature sensor with a first temperature sensor and a second temperature sensor in a protective helmet;

measuring with said first temperature sensor the temperature near the skin of the user;

measuring with said second temperature sensor the temperature in the near environment within the protective helmet;

and using the measured temperature near the skin and temperature in the near environment to determine the body core temperature of the user.

14. A body temperature measurement system, comprising:

a head strap with a strap section at least partially in contact with the scalp of a user;

a first temperature sensor for measuring the skin temperature, said strap section supporting said temperature sensor in contact with the scalp of a user;

a helmet connected to said head strap;

a second temperature sensor connected to one or more of said temperature sensor and said head strap, said first temperature sensor and said second temperature sensor being disposed in said helmet;

an evaluating circuit and a receiving station, wherein said first temperature sensor and said additional temperature sensor are connected to said evaluating circuit for transmitting measured temperature values to said receiving station, said first temperature sensor measuring the temperature near the skin of the user.

15. A system in accordance with claim 14, wherein said first temperature sensor is fastened in an area of the forehead of the user and said first temperature sensor and said second temperature sensor form a double sensor arrangement with said second temperature sensor measuring the temperature in the near environment within the protective helmet.

16. A system in accordance with claim 14, wherein said second temperature sensor is fastened to a second strap section in the area of the top side of the head of the user said second strap section supporting said second temperature sensor in contact with the scalp of a user.

17. A system in accordance with claim 14, wherein the strap section receiving said first temperature sensor is at least partially provided as a pressure-sensitive element.

18. A system in accordance with claim 14, wherein said strap sections are elements of a inner shell part of said helmet with a fixed outer shell wherein said second temperature sensor is fastened in the area between the inner part and the inner wall of the outer shell.
