Abstract: A dual micro-electromechanical actuator for providing dual actuation to a micromachine. The actuator includes a first substrate upon which a first actuating electrode is formed. A second substrate located proximate to but spaced from the first substrate supports a second actuating electrode. A micromachine device, such as a thin membrane, plate or cantilever, is disposed between the actuating electrodes. When one of the actuating electrodes is selectively activated by applying a voltage thereto, an electrostatic attraction force is produced which causes movement of the micromachine in the direction of the activated actuating electrode.

Abstract: An actuation device employing square-loop latchable magnetic material having a magnetization direction (polarization) capable of being changed in response to exposure to an external magnetic field is disclosed. The magnetic field i s created by a conductor assembly with non-solenoid configuration. Once the magnetization direction of the material is so changed, the external magnetic field is no longer required to maintain the new magnetization direction. The latchable magnetic material is disposed on the mobile electrode of a switching device, and another magnetic material is disposed in spaced relation to the latchable magnetic material on a stationary electrode or surface. By applying an electrical current to a conductor assembly arranged proximate the latchable material, a magnetic field is created about the latchable magnetic material, to change the magnetization direction and thereby enable the attraction or repulsion of another magnetic material located on t he stationary electrode. The resulting relative displacement of the mobile and stationary electrodes effects the selective connection or disconnection of electrical contacts carried on or associated with the respective electrodes of the actuation device without requiring additional power in order to maintain the switched state of theele ctrodes.

Abstract: An optical signal processing apparatus includes at least two mirror array chips mounted on an upper surface of a base in close proximity to each other to form a compound array. Each mirror array chip includes a substrate, and a plurality of spaced-apart mirrors mounted on an upper surface of the substrate. The mirrors are movable in response to an electrical signal. A plurality of electrical leads for conduct the electrical signals to the mirrors, at least a portion of the electrical leads extending at least partially along the upper surface of the base between a lower surface of the substrate and the upper surface of the base.

Abstract: An ordnance fuse apparatus (100) is described that uses electrical and mechanical, and optical devices. The ordnance fuse apparatus includes a controller (150) to control an optical switch (120) and a laser (111) to detonate an explosive charge (140) of the ordnance. Other embodiments include an accelerometer (122) and/or spin detector (123) for detecting that the ordnance has been fired and an optical detector (114) for detecting the proper operation of the laser (111) and a position sensor for detecting correct positioning of the optical switch (120). Another embodiment includes a microlens (130) to focus the laser optical signal onto the ignitor. In yet other embodiments, the explosive charge (140) is detonated either by ignition of an ignitor or by a shock wave from the ignitor. The resulting ordnance fuse apparatus (100) has significantly reduced size and improved performance and safety.

Abstract: A variable optical delay line using MEMS devices. A reflector (16a,16b) on a micro machine linear rack (18) is positioned and spaced from an input source and/or an output to receive and reflect input light waves (12a) toward the output (14a). The distance between the reflector and the input and output is variable and thereby enables selective path delay compensation of the input light wave signals. Other disclosed embodiments utilize pivoting MEMS mirrors and selective adjustment of the mirror pivot angles to provide the selective path delay compensation required in a light wave system.

Abstract: An optical crossconnect (OXC) fabric including an array of tiltable mirrors, a reflector and a plurality of optical fibers controls the position of the mirrors to optimize the transfer of a signal between an input optical fiber and an output optical fiber by monitoring the optical signal at an optical translation unit in each of the input optical fiber and the output optical fiber. The optical translation units are operable for regenerating the optical signals transmitted through the fibers.
