Hearing aid with a sensor for changing power state of the hearing aid
First Claim
1. A hearing aid comprising a first sensor for sensing a first parameter indicative of a use situation of the hearing aid, the hearing aid defining a direction parallel to the vertical direction when in a use situation,wherein the hearing aid is configured to change into a high power mode or a low power mode in response to a first control signal from the first sensor,wherein the first sensor is a three-axis accelerometer having one axis aligned with the defined direction, and wherein the hearing aid changes from the high power mode to the low power mode by:
- measuring accelerations of the hearing aid in three directions from the first sensor;
determining whether an orientation of the hearing aid deviates more than a threshold value from vertical;
determining whether a total acceleration of the hearing aid deviates less than a predetermined value from earth'"'"'s gravity; and
changing the hearing aid from the high power mode to the low power mode when the orientation deviates more than the threshold value from vertical and the total acceleration deviates less than the predetermined value from earth'"'"'s gravity in response to the first control signal from the first sensor.

Abstract
A hearing aid comprising a first sensor for sensing a first parameter indicative of a use situation of the hearing aid, wherein the hearing aid is adapted to change into a high power mode or a low power mode in response to the a first control signal from the first sensor. A second sensor for sensing a second parameter indicative of a use situation of the hearing aid may also be used as well.

18. A method of controlling a hearing aid comprising a sensor for sensing a first parameter indicative of a user situation of the hearing aid, the hearing aid defining a direction parallel to the vertical direction when in a user situation and the sensor being a three-axis accelerometer having one axis aligned with the defined direction, the method comprising:
-
measuring accelerations of the hearing aid in three directions; determining whether an orientation of the hearing aid deviates more than a threshold value from vertical; determining whether a total acceleration of the hearing aid deviates less than a predetermined value from earth'"'"'s gravity; and changing the hearing aid from a high power mode to a low power mode, when the orientation deviates more than the threshold value from vertical and the total acceleration deviates less than the predetermined value from earth'"'"'s gravity in response to the first control signal from the first sensor.

19. A method of controlling a hearing aid comprising a sensor for sensing a first parameter indicative of a user situation of the hearing aid, the hearing aid defining a direction parallel to the vertical direction when in a user situation and sensor being a three-axis accelerometer having one axis aligned with the defined direction, the method comprising:
-
measuring accelerations of the hearing aid in 3 directions; determining whether an orientation of the hearing aid deviates more than a threshold value from vertical; determining whether a total acceleration of the hearing aid deviates less than a predetermined value from earth'"'"'s gravity; and maintaining the hearing aid in low power mode as long as the determined orientation does not exceed the threshold value and the determined acceleration deviates less than the value from earth'"'"'s gravity.
