Abstract: A robust microelectromechanical switch. In an illustrative embodiment, the switch is adapted for use in a display and includes a first flexible surface and a second surface. The second surface is angled relative to the first surface, forming a wedge the first surface and the second surface. A first terminal and a second terminal are positioned relative to the first flexible surface and the second surface so that selective flexing of the flexible surface electrically couples or uncouples the first terminal to the second terminal. In a more specific embodiment, the switch further includes a first mechanism for selectively applying an electrostatic force between the first flexible surface and the second surface. The first surface is positioned on a first elastic flexible layer, and the second surface is positioned on a second layer. The first mechanism includes a first actuator electrode that is coupled to the first surface, and a second actuator electrode that is coupled to the second surface.

Abstract: Micro-electromechanical devices having an improved flexible layer enable the use of material having a wider range of elastic modulus. The MEM devices include a substantially non-pliable layer and a substantially flexible layer both of which include electrodes that when energized will create electrostatic forces that attracts the flexible layer to the non-pliable layer. The flexible layer has perforations or apertures cut into the flexible layer of a MEMs device to alter operational properties such as electrostatic sensitivity, resonance frequency, rate of change of sensitivity above the resonance frequency, oscillating mass, panel stiffness and others parameters.

Abstract: A contact magnetic storage system in which the slider, which supports the magnetic read/write head, is in physical contact with a rigid magnetic storage medium during system operation at a selected operating speed. The slider material has a load versus friction characteristic that is non-linear in the negative load region. This characteristic allows the slider to be suspended from an access arm with zero or negative external loading. In a conventional magnetic storage system, at operating speed the slider is lifted away from the surface of the storage medium by at least the thickness of the air film adjacent the moving storage medium surface. In the present invention, due to the non-linear load versus friction characteristics of the slider material, a restoring force is generated at system operating speed which overcomes the lift of the air bearing and maintaining the slider in contact with the storage medium surface without substantial wear or damage to either the slider or the storage medium.

Abstract: An electronic computer system is formed of a control processor (1) and a plurality of processor elements (3.sub.1 -3.sub.n). Each of the processor elements (3.sub.1 -3.sub.n) has a control unit (30.sub.i) that processes instructions issued by the control processor (1) in the SIMD manner, a data-driven processing unit (31.sub.i) for performing arithmetic/logic operations and data transfering to a destination processor element of the processor elements (3.sub.1 -3.sub.n) through a packet transmission network (22) in a data-driven manner and a local memory (35.sub.i). The control processor (1) broadcasts instructions to set the data-driven processing unit (31.sub.i) in each of the processor elements (3.sub.1 -3.sub.n) contents that are to be performed in the data-driven manner. In each of the processor elements (3.sub.1 -3.sub.n), operations in the data-driven processing unit (31.sub.i) based on the data-driven manner are performed in parallel with setting of the data-driven processing unit (31.sub.i).

Abstract: An optical recording system in which the optical head is operated in physical contact with the surface of the optical recording medium during system operation at a selected operating speed. The optical head includes one or more optical elements mounted on a substrate which is in physical, sliding contact with the recording medium. The substrate is fabricated from a crystalline material which has a non-linear load versus friction characteristic in the negative load region. When the head is in sliding contact with the recording medium surface, a restoring force is generated which maintains the optical head in physical contact with the recording medium overcoming any lifting forces generated by the moving air layer adjacent the recording medium surface. This allows the head to be operated with a negative external load applied.
