  • Publication number: 20080236340
    Abstract: A swage anvil includes a coupling portion that, when mated with a corresponding die of a swaging device, allows lateral positioning of the swage anvil (i.e., substantially parallel to a long axis of the saw blade) relative to the long axis of the saw blade. The swage anvil also includes a tooth contact face that substantially mirrors an angle of the back portion of each tooth of the saw blade. As such, after a manufacturer inserts the swage anvil into the swage device and laterally translates the swage anvil, the tooth contact face abuts the back portion of the saw blade tooth to support the tooth during a swaging procedure. With the aforementioned configuration of the swage anvil, translation of the swage anvil along a single axis provides support to the back portion of the saw blade tooth along two axes. As such, use of the swage anvil decreases the set-up time required in conventional swaging devices.

  • Publication number: 20080236339
    Abstract: A hand-operated swage device includes a first hand-operated actuator and a second hand operated actuator that, when actuated together, control the sequential operation of a clamping mechanism and a swaging mechanism of the hand-operated swage device. For example, the first actuator of the swage device is disposed on a first handle while the second actuator is disposed on a second handle of the swage device. To operate the hand-operated swage device, an operator grasps the first handle with one hand and grasps the second handle with his other hand to actuate both of the actuators in a substantially simultaneous manner. Actuation of both actuators controls sequential delivery of pressurized air to a first pneumatic device mechanically coupled to the clamping mechanism and to a second pneumatic device mechanically coupled to the swaging mechanism.

  • Patent number: 7394594
    Abstract: A pulsed laser beam is used to create apertures in a layer on a back side of a substrate that includes a microlens array on a front side thereof. The pulsed laser beam is focused in a vacuum spatial filter. A profile of the pulsed laser beam that emerges from the vacuum spatial filter is converted to a top hat profile. The laser beam having the top hat profile is diffused. Finally, the pulsed laser beam having the top half profile that has been diffused is impinged through the microlens array on the front side of the substrate and onto the layer on the back side of the substrate. Related apparatus for creating the apertures and microlens array products are also described.

  • Patent number: 7332197
    Abstract: Microneedle arrays are fabricated by providing a sacrificial mold including a substrate and an array of posts, preferably solid posts, projecting therefrom. A first material is coated on the sacrificial mold including on the substrate and on the array of posts. The sacrificial mold is removed to provide an array of hollow tubes projecting from a base. The inner and outer surfaces of the array of hollow tubes are coated with a second material to create the array of microneedles projecting from the base. The sacrificial mold may be fabricated by fabricating a master mold, including an array of channels that extend into the master mold from a face thereof. A third material is molded into the channels and on the face of the master mold, to create the sacrificial mold. The sacrificial mold then is separated from the master mold. Alternatively, wire bonding may be used to wire bond an array of wires to a substrate to create the sacrificial mold.

  • Patent number: 7190387
    Abstract: Optical microstructures, such as microlenses, are fabricated by rotating a cylindrical platform that includes a radiation sensitive layer thereon, about its axis, while simultaneously axially rastering a laser beam across at least a portion of the radiation sensitive layer. The cylindrical platform is also simultaneously translated axially while it is being rotated. The amplitude of the laser beam is continuously varied while rastering. The optical microstructures that are imaged in the radiation sensitive layer can be developed to provide a master for replicating a microlenses.

  • Patent number: 6942814
    Abstract: Methods of forming optoelectronic devices include forming an electrically conductive layer on a first surface of a substrate and forming a mirror backing layer from the electrically conductive layer by forming an endless groove that extends through the electrically conductive layer. A step is then performed to remove a portion of the substrate at a second surface thereof, which extends opposite the first surface. This step exposes a front surface of the mirror backing layer. An optically reflective mirror surface is then formed on the front surface of the mirror backing layer.

  • Patent number: 6596147
    Abstract: MEMS structures are provided that compensate for ambient temperature changes, process variations, and the like, and can be employed in many applications. These structures include an active microactuator adapted for thermal actuation to move in response to the active alteration of its temperature. The active microactuator may be further adapted to move in response to ambient temperature changes. These structures also include a temperature compensation element, such as a temperature compensation microactuator or frame, adapted to move in response to ambient temperature changes. The active microactuator and the temperature compensation element move cooperatively in response to ambient temperature changes. Thus, a predefined spatial relationship is maintained between the active microactuator and the associated temperature compensation microactuator over a broad range of ambient temperatures absent active alteration of the temperature of the active microactuator.

  • Patent number: 6590313
    Abstract: A MEMs microactuator can be positioned in an interior region of a frame having at least one opening therein, wherein the frame expands in response to a change in temperature of the frame. A load outside the frame can be coupled to the microactuator through the at least one opening. The microactuator moves relative to the frame in response to the change in temperature to remain substantially stationary relative to the substrate. Other MEMs structures, such as latches that can engage and hold the load in position, can be located outside the frame. Accordingly, in comparison to some conventional structures, temperature compensated microactuators according to the present invention can be made more compact by having the interior region of the frame free of other MEMs structures such as latches.
