<p>The present invention relates to a method for actuating a physical/technical process, particularly in toilette facilities, which employs a sound sensor (M) being provided with a circuit for signal analysis. This sensor (M) is located in close proximity to a liquid inlet. In a device for automatic cleaning of toilette seats (4), the sensor (M) is built in close proximity of the flushing water inlet. The flushing noises are eliminated by the use of said signal analysis circuit, whereby the cleaning of the seat (4) and exhaustion of odors via a ventilator (15) is only triggered if the flushing operation has been clearly detected.</p> |
