Abstract: A magnetic inertial force generator includes a magnetic shell internally defining an armature chamber. At least two circumferential electric coils are spaced longitudinally within the chamber and mounted on a cylindrical inner surface of the outer shell. An armature centered by springs is reciprocably supported in the chamber and includes at least two axially spaced radially magnetized permanent magnets mounted on a longitudinally extending magnetic steel tube. The magnets extend in general alignment with the coils. Controlled energizing of the coils reciprocates the armature axially relative to the shell to develop an opposite inertia force on the shell for application to a connected body. The use of multiple radially magnetized magnets provides for improved performance and/or reduced cost.

Abstract: A membrane actuator includes a magnetically actuatable membrane and a magnetic trigger. The membrane includes a shape memory alloy (SMA), and the magnetic trigger is configured to induce a martensitic transformation in the SMA, to produce a larger force than would be achievable with non-SMA-based materials. Such a membrane actuator can be beneficially incorporated into a wide variety of devices, including fluid pumps, shock absorbing systems, and synthetic jet producing devices for use in an aircraft. The membrane/diaphragm can be formed from a ferromagnetic SMA, or a ferromagnetic material can be coupled with an SMA such that the SMA and the ferromagnetic material move together. A hybrid magnetic trigger, including a permanent magnet and an electromagnet, is preferably used for the magnetic trigger, as hybrid magnetic triggers are easy to control, and produce larger magnetic gradients than permanent magnets or electromagnets alone.

Abstract: A single coil solenoid includes a permanent magnet with bidirectional assist capabilities. The solenoid includes an armature that during de-energization of a single coil of wire is attracted to the permanent magnet thereby maintaining a hold position and during energization of the single coil has a polarity that repels the permanent magnet thereby creating a push/pull force. In this regard, the permanent magnet operates to not only hold the armature but also is used to push the armature when current is induced in the single coil.

Abstract: 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.

Abstract: The invention relates to a handle with an integrated switch (20) for doors or hinged flaps of vehicles. The push-button switch is essentially made up of two components which can be fitted together. The first component (21) is made of a single-pieced injection-moulding product made of three plastic components which comprise a solid covering-shaped housing and an elastic membrane. Said membrane closes the housing cover (22) at the base on one end thereof, thus giving the component (21) a shell shape. A solid pressure activator (24) on the membrane (23) is used as the third plastic component. The second component (31) is formed from a circuit board (33) comprising connected cables (19) and a microswitch (30) mounted thereon. The second component (31) is inserted into the inside of a shell (26) of the first component (21). The circuit board (33) is oriented towards the shell opening (28) and is projected from the edge of the shell (43) of the shell-shaped component (21).

Accordingly, the general geometry of the magnet structure is fixed, and the amount of magnetic material, and therefore the magnetic field strength, is adjustable.

Abstract: A indexing wheel mounted in the head assembly of a safety switch has an axis of rotation extending at right angles to the longitudinal axis of the plunger, and against whose lateral surface the plunger bears. A key channel in the head assembly is adapted for receiving a key and into which the indexing wheel projects. A key, upon being inserted into and upon being withdrawn from the key channel positively rotates a cam plate about its axis of rotation and switches over the switch. The switch and key is maintained in locked status by action of the locking hole on the cam pin and by action of the plunger when a key is inserted into the head assembly where the plunger becomes inserted in the locking hole of the indexing wheel and/or the flank on the cam pin after rotation by the key causing the key and switch to become locked.

For example, with a numeral entry mode preset, only the key backlight for lighting the numeral display area is lighted, thus displaying only a required numeral bright in the number entry mode.

Abstract: A microelectromechanical system includes separate conducting elements. An electromechanically deformable element can be switched between a first stable position and a second stable position. Contact elements allow for electrical continuity to be established between the separate conducting elements. Switch control elements ensure that the first deformable element switches so as to establish electrical continuity between the separate conducting elements in the second stable position, by contact between the contact elements, and to break electrical continuity by separating the contact elements in the first stable position. The separate conducting elements and the contact elements are carried by the deformable element.
