Each electrode is arranged such that the faces of each electrode provided with the protuberances are facing each other, the distance separating the two faces facing each other being greater than the sum of the heights of a protuberance from the fixed electrode and a protuberance from the mobile electrode. The electrodes are capable of moving with respect to each other in two parallel planes along at least one main direction. | 2008-10-02 |
| 20080238245 | Piezoelectric switch with symbolic illumination - An element for an illuminated piezoelectric switch, comprises a substantially lens-like body having a first major surface and a second major surface, an illumination input at the first major surface, and a protrusion extending from the second major surface. The protrusion is integral to the construction of the lens. When the element is placed between a piezoelectric crystal and a pressing surface it transmits pressure to the crystal in one direction, and in the other direction it transmits light from a lighting element below, towards the protrusion. The protrusion is shaped so that the switch can be identified. | 2008-10-02 |
| 20080238246 | Electromechanical actuator - An actuator includes a frame and a shaft rotabably supported by the frame. The actuator also includes at least one wire made from a shape memory alloy having a first end thereof fixed with respect to the frame. A second end of the at least one wire is movable with respect to the frame and configured to rotate the shaft in a first direction with respect to the frame. | 2008-10-02 |
