| 20080197909 | Capacitative Proximity Switch, and Domestic Appliance Equipped With the Same - A capacitive proximity switch has an electrically conductive sensor surface, which is covered by an electrically non-conductive covering plate and which serves as a part of a capacitor with a capacitance that varies with proximity. A household appliance is equipped with a proximity switch of this type. The sensor surface has an active shielding, which is formed by a shielding surface to which a clock signal is applied at the same time as it is applied to the sensor surface. | 08-21-2008 |
| 20080224758 | Capacitive Proximity Switch, and Domestic Appliance Comprising the Same - A capacitive proximity switch includes an electrically conductive sensor area, which is covered by an electrically-insulating cover plate, as part of a capacitor having a capacitance which varies as a result of proximity. An associated evaluation circuit is provided, and an electrically-conducting body, via which the sensor area is connected to the evaluation circuit and which is arranged between the electrically-insulating cover plate and a mount disposed at a distance therefrom. A domestic appliance includes such a proximity switch. At least one electronic component of the evaluation circuit is arranged on the mount such that it protrudes into a cavity, which is surrounded by the electrically conductive body. | 09-18-2008 |
| 20080238444 | Capacitive Proximity Switch and Domestic Appliance Equipped Therewith - A capacitive proximity switch has an electrically conductive sensor surface, which is covered by an electrically non-conductive covering plate and which serves as a part of a capacitor having a capacitance that varies with proximity. The sensor surface is connected to a control input of a semiconductor switch that has a signal input with a clock signal and a signal output.
