  • Patent number: 8511229
    Abstract: A microcavity structure. In an illustrative embodiment, the microcavity structure includes a first substrate, which has a region of interest. A second substrate with a perforation therein is bonded to the first substrate. The perforation coincides with the region of interest. In a specific embodiment, the first substrate is implemented via a Printed Circuit Board (PCB). The region of interest includes one or more circuit components, including an actuator, such as a bridgewire, thereon or therein. A smoothing layer is included between the PCB and the actuator. A bonding gasket adheres the first substrate to the second substrate. The perforation accommodates energetic material that is selectively ignited via the actuator.

  • Patent number: 7938065
    Abstract: An actuator assembly that includes, in one example embodiment, a substrate with a bridge coupled between a first electrode and a second electrode on the substrate. A lithographically disposed flyer is positioned in proximity to the bridge. In a more specific embodiment, the actuator assembly further includes a lithographically disposed barrel that partially surrounds the flyer. A fireset is coupled to pins that extend through the substrate to the first electrode and the second electrode. The flyer further includes a three-dimensional surface adapted to flatten during flight. The flyer may be concave, convex, or may star shaped, may have perforations therein, or may exhibit another shape or other features.

  • Patent number: 7021217
    Abstract: A versatile cavity actuator. The versatile cavity actuator includes a cavity having one or more polymer-based sidewalls. An energetic material is disposed therein. A heater is disposed on or within the cavity. In a specific embodiment, the cavity includes a thermally insulating base positioned beneath the heater, which is positioned near the bottom of the cavity. The polymer-based sidewalls are constructed from a photo-curable epoxy, which is disposed on a substrate via microelectromechanical processes. The sidewalls are angled or parabolic and are constructed via a low-temperature lithographic spin process compatible with post integrated circuit processing.

  • Patent number: 6185084
    Abstract: Methods and apparatus implementing a technique for electrostatically transporting a particle through a medium. In general, one implementation includes a substrate; a first insulation layer formed on the substrate; a plurality of electrodes arranged in a sequence on the insulation layer, where the electrodes are divided into a plurality of groups and the electrodes are arranged by group; a second insulation layer over at least one of the electrodes; and a phase shift circuit connected to the electrodes which supplies a voltage wave-form to each group of electrodes, where each voltage wave-form for each group is phase-shifted relative to the other phase-shifted wave-forms.

  • Patent number: 5921678
    Abstract: A micromachined, high Reynolds number, sub-millisecond liquid mixer for the study of chemical reaction kinetics. This bulk micromachined silicon mixer is capable of initiating and quenching chemical reactions in intervals as short as 100 .mu.s. The mixer chip contains two tee mixers connected by one channel which serves as a reaction chamber. Each tee mixer consists of opposing channels where liquids meet head-on and exit into a third channel forming the base of a "T".

  • Patent number: 5629918
    Abstract: A surface micromachined micromagnetic actuator is provided with a flap capable of achieving large deflections above 100 microns using magnetic force as the actuating force. The flap is coupled by one or more beams to a substrate and is cantilevered over the substrate. A Permalloy layer or a magnetic coil is disposed on the flap such that when the flap is placed in a magnetic field, it can be caused to selectively interact and rotate out of the plane of the magnetic actuator. The cantilevered flap is released from the underlying substrate by etching out an underlying sacrificial layer disposed between the flap and the substrate. The etched out and now cantilevered flap is magnetically actuated to maintain it out of contact with the substrate while the just etched device is dried in order to obtain high release yields.
