摘要： A micromachined electromagnetic switch, including two soft magnets situated in fixed positions above and below a permanent magnet, toggles between two fixed positions by the application of current in an actuator coil for a brief period. The permanent magnet is attached to a micromachined hinge or spring which moves under the action of a net force, thereby opening or closing the switch. Current in the actuator coil changes the relative strength of the magnetic forces due to the soft magnets. In the absence of current in the actuator coil, the switch is kept in the open or closed position by the attractive magnetic force between the permanent magnet and either the upper or lower soft magnet, whereby the stronger force is exercised between the permanent magnet and the nearest soft magnet.

摘要： Micromachining methods for fabricating micromechanical structures which include plunger elements free to reciprocate within cavities are fabricated using processing steps in common with those employed in high density interconnect (HDI) technology for multi-chip module packaging. A polymer, such as a polyimide, is utilized as a micromachinable material. In one embodiment, cavities are formed in the polymer material by laser ablation, employing a sacrificial layer as a mask. Electroplated copper may be employed as a sacrificial release layer. One particular structure is a micromechanical electric switch including an array of individual switch contacts actuatable in common.

摘要： A circuit interruption device having a plurality of micromechanical switches mounted on a substrate in a parallel-series array. The array includes a plurality of line branches connected in parallel in a circuit line. Each of the line branches has at least two of the switches serially connected therein. The micromechanical switches each has a pair of contacts formed on the substrate, a bridging contact movably formed on the substrate, and an actuator for causing the bridging contact to move in and out of contact with the contacts. The bridging contact can be either a member slidably disposed in a channel formed on the substrate or member attached to an end of a cantilever having its other end attached to the substrate. The actuator is controlled by a trip device which is also mounted on the substrate. The trip device senses the current in the circuit line and causes the switches to open when a predetermined level of current in the line is exceeded.

摘要： A brush seal includes a plurality of bristles in a circumferential array secured to a fixed component and about a rotary component. The bristles are cantilevered toward the rotary component at an angle to the radii of the rotary component with the bristle tips engaged against the rotary component. The bristles are supported by plates on opposite axial sides of the bristles. The plates have channels for directing fluid under pressure into the channels and against the bristles to deflect or bend the bristles toward the rotary component so that the tips of the bristles bear against the surface of the rotary component, enhancing the seal.
