    摘要： MEMS structures employing movable conductive member and a number of current-carrying stationary contact terminals which advantageously permit higher current carrying capability that prior art devices in which currents flowed through movable conductive members. Current carrying capability in excess of 1.0 amp without the need for additional current limiting devices is realized thereby lowering overall system manufacturing costs for systems employing our structures.

    摘要： Apparatus for a micro-electro-mechanical switch that provides single pole, double throw switching action. The switch has two input lines and two output lines. The switch has a seesaw cantilever arm with contacts at each end that electrically connect the input lines with the output lines. The cantilever arm is latched into position by frictional forces between structures on the cantilever arm and structures on the substrate in which the cantilever arm is disposed. The state of the switch is changed by applying an electrostatic force at one end of the cantilever arm to overcome the mechanical force holding the other end of the cantilever arm in place.

    摘要： A separated MEMS thermal actuator is disclosed which is largely insensitive to creep in the cantilevered beams of the thermal actuator. In the separated MEMS thermal actuator, a inlaid cantilevered drive beam formed in the same plane, but separated from a passive beam by a small gap. Because the inlaid cantilevered drive beam and the passive beam are not directly coupled, any changes in the quiescent position of the inlaid cantilevered drive beam may not be transmitted to the passive beam, if the magnitude of the changes are less than the size of the gap.

    摘要： A MEMS hysteretic thermal device may have a cantilevered beam which bends about one or more points in at least two substantially different directions. In one exemplary embodiment, the MEMS hysteretic thermal device is made from a first segment coupled to an anchor point, and also coupled to a second segment by a joint. Heating two respective drive beams causes the first segment to bend in a direction substantially about the anchor point and the second segment to bend in a direction substantially about the joint. By cooling the first drive beam faster than the second drive beam, the motion of the MEMS thermal device may be hysteretic. The MEMS hysteretic thermal device may be used for example, as an electrical switch or as a valve or piston.

    摘要： A two-stage acceleration sensing apparatus is disclosed which has applications for use in a fuze assembly for a projected munition. The apparatus, which can be formed by bulk micromachining or LIGA, can sense acceleration components along two orthogonal directions to enable movement of a shuttle from an “as-fabricated” position to a final position and locking of the shuttle in the final position. With the shuttle moved to the final position, the apparatus can perform one or more functions including completing an explosive train or an electrical switch closure, or allowing a light beam to be transmitted through the device.

    摘要： A microelectromechanical (MEM) apparatus is disclosed which includes a shuttle suspended above a substrate by two or more sets of tensile-stressed beams which are operatively connected to the shuttle and which can comprise tungsten or a silicon nitride/polysilicon composite structure. Initially, the tensile stress in each set of beams is balanced. However, the tensile stress can be unbalanced by heating one or more of the sets of beams; and this can be used to move the shuttle over a distance of up to several tens of microns. The MEM apparatus can be used to form a MEM relay having relatively high contact and opening forces, and with or without a latching capability.
