  • Tiled manifold for a page wide printhead
    Patent number: 8313167
    Abstract: An ink manifold constructed with a number of semiconductor tiles which are fastened end to end on a rigid base member to form a page wide print mechanism. Each tile is constructed with ink channels on one side in liquid communication with ink outlet ports on the opposite side. The ink channels carry ink from ports in the base member to the outlet ports of the tiles. The interface between each tile defines a boundary. An inkjet printhead is fastened over each boundary of the tiled manifold so that the ink inlet ports of the printhead are aligned with the ink outlet ports of the underlying tiles. No ink passes across the boundary of the adjacent manifold tiles. The fabrication of the individual tiles from a semiconductor wafer facilitates usage of the wafer when fabricating page wide print mechanisms.

  • FORCE MEASUREMENT
    Publication number: 20120255500
    Abstract: A rodent enclosure dimensioned in length, width and height so as to allow a rodent to run freely along the length of the enclosure, but not turn around without standing on its hind legs. The enclosure has a floor with bars extending transversely to allow access for a force sensor's probe from below. A force measurement device for use with the rodent enclosure to measure the tactile response of a rodent comprising a measurement probe connected to a device body. The probe has a tip which can be engaged with a rodent's paw through the floor of the enclosure. The device body has a fixed body part and a rotatable body part arranged to allow relative rotation between them. A rotation sensor detects the relative rotation and outputs a measurement parameter having values that are calibrated against force values associated with forces applied to the probe's tip.

  • LAMINATE CONSTRUCTS FOR MICRO-FLUID EJECTION DEVICES
    Publication number: 20110292124
    Abstract: A micro-fluid ejection head has an ejection chip to expel fluid. It connects to a laminate construct. The construct has vertically configured wiring layers interspersed with non-conductive layers, such as carbon fiber layers. An upper of the wiring layers electrically connects to the ejection chip. The upper layer may also support a planar undersurface of the chip directly on a surface or in a recessed pocket. The two can connect with a die bond, such as one having silica or boron nitride. Fluid connections exist between ink feed slots of the chip and the laminate construct. A silicon tile or other material may also fluidly interconnect with the two. A plastic manifold optionally supports the laminate construct and may fluidly connect to it. The wiring layers of the laminate contemplate ground, power, and various bond pads. Other construct layers contemplate prepreg or core FR4 layers.

  • MEMS switch capping and passivation method
    Patent number: 7968364
    Abstract: A MEMS switch with a platinum-series contact is capped through a process that also passivates the contact by controlling, over time, the amount of oxygen in the environment, pressures and temperatures. Some embodiments passivate a contact in an oxygenated atmosphere at a first temperature and pressure, before hermetically sealing the cap at a higher temperature and pressure. Some embodiments hermetically seal the cap at a temperature below which passivating dioxides will form, thus trapping oxygen within the volume defined by the cap, and later passivate the contact with the trapped oxygen at a higher temperature.
