Abstract
A method for operating a door-opening mechanism of a household appliance includes: providing a first signal using a door-opening sensor; providing a second signal using the door-opening sensor; and providing a third signal using the door-opening sensor. A total signal is calculated based on the first, second and third signals so as to determine a spatial direction from which a signal source originates.
Claims4
1:
- A method for operating a door-opening mechanism of a household appliance, the method comprising:
- providing a first signal using a door-opening sensor;
- providing a second signal using the door-opening sensor;
- providing a third signal using the door-opening sensor;
- and
- calculating a total signal based on the first, second and third signals so as to determine a spatial direction from which a signal source originates.
3 more elements
2:
- The method recited in claim 1, wherein the first, second and third signals are filtered so as to provide a limited frequency band.
3:
- The method recited in claim 1, wherein a spectral analysis of the first, second and third signals is calculated or evaluated.
4:
- The method recited in claim 1, wherein acceleration integrals of the first, second and third signals are calculated or evaluated.
