Abstract

A method for operating a hearing device having a charging terminal with two electrical contacts includes detecting a decrease in the voltage applied to one of the two contacts. An operating mode of the hearing device is set based on the time profile of the decrease. A hearing device and a system including a hearing device and a charging device, are also provided.

First claim

The invention claimed is:

1. A method for operating a hearing device, the method comprising:
providing a hearing device including a charging terminal with two electrical contacts;
charging the hearing device by an interaction with a charging device applied to the two electrical contacts;
detecting a decrease in a voltage applied to one of said two electrical contacts due to the interaction with the charging device; and
setting different operating modes of the hearing device based on a time profile of the decrease by:
selecting one of the operating modes as a standby operating mode when the voltage decreases more slowly than a first limit value during non-use of the hearing device by a user, and switching off at least some components of the hearing device or operating at least one of the components with a comparatively low energy demand with a restricted range of functions, in the standby operating mode; and
selecting another of the operating modes as a working mode when the voltage decreases more rapidly than a second limit value during use of the hearing device by a user, and energizing some of the components of the hearing device having not yet been energized and switching the components having not yet been energized from the standby operating mode to the working mode.

2. The method according to claim 1 , which further comprises determining the time profile by detecting the voltage only at two different times.

3. The method according to claim 1 , which further comprises producing a temporal derivation of the voltage to determine the time profile.

4. The method according to claim 1 , which further comprises detecting a decrease when the voltage applied to the two contacts falls below a third limit value.

5. A hearing device, comprising:
a charging terminal having two electrical contacts; and
electronics operating the hearing device in accordance with the method of claim 1 .

6. The hearing device according to claim 5 , which further comprises an A/D converter for ascertaining the time profile of the decrease.

7. A system, comprising:
a charging device having two electrical mating contacts;
a capacitance electrically interconnecting said two electrical mating contacts; and
a hearing device according to claim 5 .
