First Claim
Patent Images
1. A method for detecting an actuation of a hand-held control for an electromotive furniture drive, wherein the hand-held control has at least one detector, comprising the steps of:
- applying an electric periodic test signal from at least one evaluation unit to at least one sensor surface of at least one detector via detector conductor paths, wherein the at least one evaluation unit is connected to the at least one detector in an electrically conducting manner;
recording a response signal by means of a test signal modified by actuation of the at least one detector;
evaluating the test signal thus obtained using the at least one evaluation unit and producing a logic switching signal for detecting the actuation of the hand-held control,wherein a height of a signal level of the response signal of the sensor surface of the detector is previously assigned to a related actuation.

6. An electromotive furniture drive for adjustment of a movable component of an item of furniture, said electromotive furniture drive comprising at least one hand-held control which includes at least one detector, and at least one control panel section having at least one actuation surface which cooperates with the at least one detector, and which is detected by applying an electric periodic test signal from at least one evaluation unit to at least one sensor surface of at least one detector, recording a response signal by means of a test signal modified by actuation of the at least one detector, evaluating the test signal thus obtained and producing a logic switching signal for detecting the actuation of the hand-held control, wherein a height of a signal level of the response signal of the sensor surface of the detector is previously assigned to a related actuation.
