Electronic circuit for headset
First Claim
1. An electronic circuit for processing signals originating from respective signal recorders, each of said signal recorders being integrated in a respective earpiece of a headset, comprising:
- a first input for receiving a first signal from the signal recorder of the ear piece intended for a left ear of a wearer of the headset, said first signal relating to a blood pressure pulse of said wearer;
a second input for receiving a second signal relating to said blood pressure pulse from the signal recorder of the ear piece intended for a right ear of the wearer;
a detection unit for detecting the order in the first signal and the second signal are recorded by said respective signal recorders and for comparing the detected order with a correct order; and
a signal adaptation unit for adapting an output signal in response to the detection unit signaling a detection of an incorrect order of the first signal and the second signal.

Abstract
An electronic circuit (100) is disclosed for processing signals (20L, 20R) originating from respective signal recorders (20) integrated in respective earpieces of a headset. The electronic circuit comprises a first input for receiving a signal (20L) from the signal recorder of the ear piece intended for a left ear of a wearer of the headset, said signal relating to a blood pressure pulse (200) of said wearer; a second input for receiving a further signal (20R) relating to said blood pressure pulse from the signal recorder of the ear piece intended for a right ear of the wearer; a detection unit (110, 120) for detecting the order in the signal and the further signal are recorded by said respective signal recorders and for comparing the detected order with a correct order; and a signal adaptation unit (130) for adapting an output signal (30L, 30R) in response to the detection unit signaling a detection of an incorrect order of the signal and the further signal. A method for detecting the placement of an earpiece of a headset in the intended ear (10) of the wearer of the headset is also disclosed.

14. A method of detecting the placement of an earpiece of a headset in an intended ear of a wearer of the headset, comprising:
-
receiving a first signal from a signal recorder of the ear piece intended for a left ear of the wearer of the headset, said first signal relating to a blood pressure pulse of said wearer; receiving a second signal relating to said blood pressure pulse from a signal recorder of an ear piece intended for a right ear of the wearer; detecting an order in which the first signal and the second signal are recorded by said respective signal recorders; comparing the detected order with a correct order; and adapting an output signal in response to the detection of an incorrect order of the first signal and the second signal. - View Dependent Claims (15)
