Abstract

With the date transmission in a hearing device system, overloads are to be avoided and the energy consumption during transmission is to be kept as low as possible. To this end, a transmission method and a corresponding system for the inductive transmission is proposed, in which the receiver returns an item of quality information relating to the received signal back to the transmitter. The transmission power of the transmitter is then dynamically varied as a function of the item of quality information. With unidirectional transmission, the transmitter can obtain an item of distance information relating to the distance of the receiver from the transmitter and thereupon adjust the transmission power accordingly.

Claims

1-9. -9. (canceled)

10. A transmission method for the inductive transmission in hearing devices and hearing device accessories, comprising

transmitting a signal from a transmitter to a receiver with a specific transmission power;

returning an item of quality information via the received signal from the receiver to the transmitter; and

dynamically modifying the transmission power as a function of the item of quality information.

11. The transmission method as claimed in claim 10, wherein the item of quality information includes an item of information relating to the received signal strength.

12. The transmission method as claimed in claim 10, wherein the item of quality information includes an item of information relating to the bit error rate of the received signal.

13. The transmission method as claimed in claim 10, wherein the transmission power being reduced or increased until the received signal has reached a predetermined minimal quality.

14. A hearing device system, comprising:

a transmitter that inductively transmits a signal to a receiver with a specific transmission power,

wherein the receiver inductively returns an item of quality information via the received signal to the transmitter, and

wherein the transmission power of the transmitter is dynamically modified as a function of the item of quality information.

15. The hearing device system as claimed in claim 14, wherein the item of quality information includes an item of information relating to the received signal strength.

16. The hearing device system as claimed in claim 14, wherein the item of quality information includes an item of information relating to the bit error rate of the received signal.

17. The hearing device system as claimed in claim 14, wherein the transmission power being reduced or increased until the received signal has reached a predetermined minimal quality.

19. The transmission method as claimed in claim 15, wherein the detection of the distance information being carried out on the basis of a misalignment of a transmitting coil of the transmitter.

20. The transmission method as claimed in claim 15, wherein the detection of the distance information being carried out on the basis of a radiated transmission power.

18. A transmission method for the inductive transmission in hearing devices and hearing device accessories, comprising:

transmitting a signal from a transmitter to a receiver with a specific transmission power,

detecting an item of distance information through the transmitter relating to a distance of the receiver from the transmitter; and

dynamic modifying the transmission power as a function of the distance information.

21. A hearing device system, comprising

a transmitter that inductive transmits a signal to a receiver with a specific transmission power;

and

a sensor for detecting distance information relating to a distance of the receiver from the transmitter is connected to the transmitter;

wherein the transmission power of the transmitter being able to be dynamically modified as a function of the distance information.

22. The hearing device system as claimed in claim 21, wherein the detection of the distance information being carried out on the basis of a misalignment of a transmitting coil of the transmitter.

23. The hearing device system as claimed in claim 21, wherein the detection of the distance information being carried out on the basis of a radiated transmission power.
