    Abstract: Bistable latching actuator for use in optical fiber switching applications having a generally planar mechanism with an arm that carries a mirror for movement in a direction perpendicular to the plane of the mechanism, and a bistable mechanical latch for retaining the mirror in stable positions on opposite sides of the plane without contacting the arm. Movement between the two stable positions is initiated and damped with an electrostatic comb drive.

    Abstract: A method and system for releasing MEMS cover-structure on a wafer is disclosed. It includes at least one MEMS wafer structure made up of two wafers, one protective cover, and one containing at least one MEMS feature that are bonded together by various standard wafer bonding means. Also, one wafer substrate with patterned aluminum features and input/output pads. The method and system comprise providing for a built in channels between the said first cover wafer, and second said MEMS wafer allowing for a saw blade to cut a channel into the cover wafer, while the MEMS wafer providing for protection against saw slurries to get over the contact pad area on the said substrate wafer. Providing a tab area over the at least one bond pad and the dicing of the tab area to remove at least a portion of tab area above the at least one bond pad. A method and system of using industry dicing techniques to release the MEMS cover-structure from the substrate is disclosed. Dicing is much more benign chemically and is compatible with a much greater range of materials. The cost of dicing and complexity of infrastructure required are much less than that required for DRIE. Also, unlike conventional methods, a dicing release does not require an additional masking step.

    Abstract: Optical fibers are aligned in a jig of parallel apertured plates in which the fibers are inserted and positioned by the use of V-shaped or positioning ribbon actuators. The actuators are thermally actuated by a closed loop feedback system to center each individual fiber and its light output on an equivalent juxtaposed photodetector array. When the fiber is centered by this feedback technique it is permanently fixed in that position by potting, for example. The feedback control constitutes either a totally electrical system utilizing a processing unit or can be partially manually controlled by a human operator operating a joystick and viewing a meter or similar device which indicates an approach to a maximum output from a photodetector.

    Abstract: A micromachined magnetic field sensor integrated with electronics is disclosed. The magnetic field sensors utilize Hall-effect sensing mechanisms to achieve 3-axis sensing. A Z axis sensor can be fabricated either on a device layer or on a conventional IC substrate with the design of conventional horizontal Hall plates. An X and Y axis sensor are constructed on the device layer. In some embodiments, a magnetic flux concentrator is applied to enhance the performance of the magnetic field sensor. In some embodiments, the magnetic field sensors are placed on slope sidewalls to achieve 3-axis magnetic sensing system. In some embodiments, a stress isolation structure is incorporated to lower the sensor offset. The conventional IC substrate and device layer are connected electrically to form a 3-axis magnetic sensing system. The magnetic field sensor can also be integrated with motion sensors that are constructed in the similar technology.

    Abstract: A fiber optic switch using MEMS is scalable by the use of a matrix of cross-points located at the intersection of all possible input and output light paths. Cross-points are formed by a MEMS procedure where a digitally movable mirror intersects a light path to provide a digital switching action with the remaining cross-point mirrors being moved out of position to provide through transmission.

    Abstract: Acoustic printheads having an optically transparent substrate, at least two optical lenses, which may be part of the substrate, and a first structure, which may also be part of the substrate. The optical lenses focus light which irradiates the substrate into optical focal points at known locations relative to the first structure. The first structure may be part of an acoustic droplet ejector which includes an acoustic lens that is fabricated on the optically transparent substrate. The optical focal points can be used to precisely align the first structure with another structure.
