  • Patent number: 8247879
    Abstract: A micromechanical device assembly includes a micromechanical device enclosed within a processing region and a lubricant channel formed through an interior wall of the processing region and in fluid communication with the processing region. Lubricant is injected into the lubricant channel via capillary forces and held therein via surface tension of the lubricant against the internal surfaces of the lubrication channel. The lubricant channel containing the lubricant provides a ready supply of fresh lubricant to prevent stiction from occurring between interacting components of the micromechanical device disposed within the processing region.

  • Patent number: 8096665
    Abstract: A high-resolution image is generated using multiple spatially offset lower-resolution digital micro-mirror device (DMD) panels. Multiple lower-resolution subframe signals for controlling the spatial light modulators are generated from a high-resolution image signal using a resolution reduction and interpolation algorithm. The spatial light modulators under control of the subframe signals are illuminated by a light source and light beams reflected from the spatial light modulators are combined and directed onto a screen for display.

  • Patent number: 8022520
    Abstract: A system for hermetically sealing devices. The system includes a substrate, which includes a plurality of individual chips. Each of the chips includes a plurality of devices and each of the chips are arranged in a spatial manner as a first array. The system also includes a transparent member of a predetermined thickness, which includes a plurality of recessed regions arranged in a spatial manner as a second array and each of the recessed regions are bordered by a standoff region. The substrate and the transparent member are aligned in a manner to couple each of the plurality of recessed regions to a respective one of said plurality of chips. Each of the chips within one of the respective recessed regions is hermetically sealed by contacting the standoff region of the transparent member to the plurality of first street regions and second street regions using at least a bonding process to isolate each of the chips within one of the recessed regions.

  • Patent number: 7952786
    Abstract: One embodiment of an micromechanical device includes a first contact surface, a moveable component having a second contact surface, and a coating of liquid or solid lubricant on at least one of the contact surfaces, where the second contact surface interacts with the first contact surface during device operation, and a gas-phase lubricant is disposed between the first contact surface and the second contact surface, where the gas-phase lubricant is adapted to increase the usable lifetime of the liquid or solid lubricant coating on the contact surfaces. One advantage of the disclosed device is that a gas-phase lubricant has a high diffusion rate and, therefore, is self-replenishing, meaning that it can quickly move back into a contact region after being physically displaced from the region by the contacting surfaces of the device during operation.

  • Publication number: 20110111544
    Abstract: A MEMS mirror for a laser printing application includes providing a CMOS substrate including a pair of electrodes, and providing a reflecting mirror moveable over the substrate and the electrodes. Voltages applied to the electrodes create an electrostatic force causing an end of the mirror to be attracted to the substrate. A precise position of the mirror can be detected and controlled by sensing a change in capacitance between the mirror ends and the underlying electrodes.

  • Patent number: 7923789
    Abstract: The contrast offered by a spatial light modulator device may be enhanced by positioning nonreflective elements such as supporting posts and moveable hinges, behind the reflecting surface of the pixel. In accordance with one embodiment, the reflecting surface is suspended over and underlying hinge-containing layer by integral ribs of the reflecting material defined by gaps in a sacrificial layer. In accordance with an alternative embodiment, the reflecting surface is separated from the underlying hinge by a gap formed in an intervening layer, such as oxide. In either embodiment, walls separating adjacent pixel regions may be recessed beneath the reflecting surface to further reduce unwanted scattering of incident light and thereby enhance contrast.
