Publication number: 20090273567Abstract: Methods and devices are provided for inputting data via a thumboard utilizing a seven (7) column by five (5) row matrix hosting 30 keys. These keys can be dynamically variable using visually alternating indicia and can provide over 150 key inputs including characters, numbers, functions, symbols, navigation controls, media controls, phone keypad characters, and special characters. The switching of key values can be controlled by either a mechanical means or a touch-sensitive matrix overlaying a low-powered key emulator—such as electronic paper (Electrophoretic Display material). Mouse pointer control and special feature keys can be arrayed around the core key layout to provide full keyboard functionality. The thumboard can be detachable for wireless remote control of a paired computing device, such as a PDA pico-projection phone.Type: ApplicationFiled: May 1, 2009Publication date: November 5, 2009Inventors: Milton E. Milley, John-Michael Carolan

Publication number: 20070166570Abstract: A method of joining at least two sintered bodies to form a composite structure, includes: providing a joint material between joining surfaces of first and second sintered bodies; applying pressure from 1 kP to less than 5 MPa to provide an assembly; heating the assembly to a conforming temperature sufficient to allow the joint material to conform to the joining surfaces; and further heating the assembly to a joining temperature below a minimum sintering temperature of the first and second sintered bodies. The joint material includes organic component(s) and ceramic particles. The ceramic particles constitute 40-75 vol. % of the joint material, and include at least one element of the first and/or second sintered bodies. Composite structures produced by the method are also disclosed.Type: ApplicationFiled: January 17, 2006Publication date: July 19, 2007Inventors: Raymond Cutler, Kent Hutchings, Brian Kleinlein, Michael Carolan

Publication number: 20070137478Abstract: An ion transport membrane system comprising (a) a pressure vessel having an interior, an exterior, an inlet, and an outlet; (b) a plurality of planar ion transport membrane modules disposed in the interior of the pressure vessel and arranged in series, each membrane module comprising mixed metal oxide ceramic material and having an interior region and an exterior region, wherein any inlet and any outlet of the pressure vessel are in flow communication with exterior regions of the membrane modules; and (c) one or more gas manifolds in flow communication with interior regions of the membrane modules and with the exterior of the pressure vessel. The ion transport membrane system may be utilized in a gas separation device to recover oxygen from an oxygen-containing gas or as an oxidation reactor to oxidize compounds in a feed gas stream by oxygen permeated through the mixed metal oxide ceramic material of the membrane modules.Type: ApplicationFiled: January 29, 2007Publication date: June 21, 2007Inventors: VanEric Stein, Michael Carolan, Christopher Chen, Phillip Armstrong, Harold Wahle, Theodore Ohrn, Kurt Kneidel, Keith Rackers, James Blake, Shankar Nataraj, Rene Hendrik Elias van Doom, Merrill Wilson

Publication number: 20070125425Abstract: A gas flow isolation device includes a gas flow isolation valve movable from an opened condition to a closed condition. The module isolation valve in one embodiment includes a rupture disk in flow communication with a flow of gas when the module isolation valve is in an opened condition. The rupture disk ruptures when a predetermined pressure differential occurs across it causing the isolation valve to close. In one embodiment the valve is mechanically linked to the rupture disk to maintain the valve in an opened condition when the rupture disk is intact, and which permits the valve to move into a closed condition when the rupture disk ruptures. In another embodiment a crushable member maintains the valve in an open condition, and the flow of gas passed the valve upon rupturing of the rupture disk compresses the crushable member to close the isolation valve.Type: ApplicationFiled: December 7, 2005Publication date: June 7, 2007Inventors: Michael Carolan, John Cooke, Michael Buzinski

Publication number: 20070079703Abstract: Ion transport membrane oxidation system comprising an enclosure having an interior and an interior surface, inlet piping having an internal surface and adapted to introduce a heated feed gas into the interior of the enclosure, and outlet piping adapted to withdraw a product gas from the interior of the enclosure; one or more planar ion transport membrane modules disposed in the interior of the enclosure, each membrane module comprising mixed metal oxide material; and a preheater adapted to heat a feed gas to provide the heated feed gas to the inlet piping, wherein the preheater comprises an interior surface. Any of the interior surfaces of the enclosure, the inlet piping, and the preheater may be lined with a copper-containing metal lining. Alternatively, any of the interior surfaces of the inlet piping and the preheater may be lined with a copper-containing metal lining and the enclosure may comprise copper.Type: ApplicationFiled: October 11, 2005Publication date: April 12, 2007Inventors: Michael Carolan, Eric Minford, William Waldron

Patent number: 7157873Abstract: A system for reducing torque disturbance includes a motor mechanically coupled to an endless belt. The motor is operable to drive the belt, and the belt has a seam that causes a torque disturbance to the system. The system includes a data structure having a set of values that indicates an amount of compensation for reducing the torque disturbance and a controller electrically coupled with the motor. The controller is configured to control the motor and reduce the torque disturbance based on the set of values in the data structure.Type: GrantFiled: May 2, 2005Date of Patent: January 2, 2007Assignee: Xerox CorporationInventor: Kevin Michael Carolan

Patent number: 6676036Abstract: A fluid ejecting method and system include one or more fluid ejectors within a fluid ejector frame and an interposer frame and movably mounted upon a fluid ejector carriage. The fluid ejector carriage traverses across a recording medium for placing swaths of fluid droplets upon the recording medium. A biasing structure urges the fluid ejector frame to a first position to obtain highly accurate and repeatable placement of fluid droplets when the fluid ejector frame is in the first position. A second position of the fluid ejector frame is achieved by energizing a position actuator to move the fluid ejector frame from the first position to the second position to obtain highly accurate and repeatable placement of fluid droplets when the fluid ejector frame is in the second position. The recording medium is advanced separately upon completing a set of at least one swath of fluid droplets.Type: GrantFiled: April 25, 2001Date of Patent: January 13, 2004Assignee: Xerox CorporationInventors: David G. Anderson, Kevin Michael Carolan, David T. Zawadzki
