| 20110006874 | MICROMECHANICAL ACTUATOR - A micromechanical actuator includes a movable first spring element having metal and/or silicon. The first spring element is fitted at a first point and can move freely at a second point. A second spring element connected to the first spring element has silicon and is partially arranged on an electrically insulating material which is applied to a substrate. The second spring element is arranged at a distance from the substrate above the substrate on a first plane, and the first spring element is arranged above the second spring element on a second plane which is at a distance from the first plane such that the first and second spring elements can move with respect to the substrate. The actuator has a third spring element which is mechanically coupled to the first spring element. The elastic deformation of the second spring element can be induced by a length change of the third spring element. | 01-13-2011 |

| 20120068811 | METHOD OF THERMALLY OPERATING AN ELECTRICAL INTERRUPT SWITCH - A thermally activated electrical interrupt device incorporates a thermally activated portion engaging with an electrical interrupt portion. The thermally activated material expands when heated, causing an interrupt control rod to open an electrical contact. When the interrupt device is placed into an interrupt state, a reset mechanism maintains the interrupt control rod in the interrupt state until specifically reset. An actuating shaft is in operational communication with at least one electrical contact. The actuating shaft is maintained in a thermal monitoring position until an interrupt control rod is moved via a thermally expanding material and engages with the actuating shaft, releasing it from the thermal monitoring position. The actuating shaft is projected via a biasing member to cause a change in state of the electrical contact. The actuating shaft remains in the interrupt state until the user resets the switch. | 03-22-2012 |
