Patent ID: 6944526

Claim:
Method for the transmission of a sensor a data signal (s 11 ) and an additional data signal (s 14 ) from a sensor assembly ( 1 ) to at least one receiver ( 2 ) of the sensor data signal and one receiver ( 3 , 5 ) of the additional data signal through a common transmission channel ( 4 ), a) whereby a sensor ( 11 ) measures a quantity that is to be measured and generates a corresponding sensor data signal, b) the receiver ( 2 ) of the sensor data signal (s 11 ) controls an application unit dependent on the sensor data signal, wherein the receiver ( 2 ) of the sensor data signal compares the sensor data signal with a threshold value (x 2 ), and activates the application unit only if the sensor data signal (s 11 ) exceeds the threshold value (x 2 ), c) whereby a total value range of the sensor data signal (x 0 -xn) includes a value range (x 0 -x 1 ) that is uncritical for the control of the application unit, d)in response to a control signal (s 3 /s 5 /s 15 /sl 6 /Uon), a data transmission unit ( 13 ) of the sensor assembly ( 1 ) at least temporarily for a short time transmits an additional data signal (s 14 ) instead of the sensor data signal (s 11 ), whereby the value range that is below the threshold value and that is uncritical for the control of the application unit is used as the signal value range for the additional data signal (s 14 ).
