Patent number: 9126411Abstract: A fluid-jet precision-dispensing device includes a layer, one or more first holes within the layer, and one or more second holes within the layer. The first holes are adapted to pass fluid therethrough during usage of the device to precisely dispense the fluid at accurately specified locations. The second holes are adapted to not pass the fluid therethrough during usage of the device to precisely dispense the fluid at the accurately specified locations. The second holes may be adapted to at least substantially maximally pass gaseous bubbles therethrough during performance of a priming operation of the device. The second holes may be adapted to at least substantially maximally pass sludge and/or contaminants therethrough during performance of the priming operation of the device.Type: GrantFiled: May 25, 2008Date of Patent: September 8, 2015Assignee: Hewlett-Packard Development Company, L.P.Inventors: Elizabeth A.

Publication number: 20110164080Abstract: Systems, methods, and other embodiments associated with fluid-jet dispensers are described. In one embodiment, a method (400) controls a fluid jet dispenser. The fluid jet dispenser includes a plurality of nozzles for precisely ejecting fluid and a plurality of ejection chambers. The fluid-jet dispenser includes one or more fluid channels for supplying fluid from a fluid reservoir to the plurality of ejection chambers and corresponding nozzles. The method includes detecting (405) that the fluid-jet dispenser has not ejected fluid for a predetermined time. The method applies a de-prime pressure (410). The de-prime pressure is a negative pressure to withdraw fluid from the nozzles and the ejection chambers to a high capillary force area within each of the one or more fluid channels to remove fluid from the plurality of nozzles.Type: ApplicationFiled: October 14, 2008Publication date: July 7, 2011Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, LP.Inventors: James W. Ring, Gilbert G. Smith

Patent number: 7499214Abstract: A projection screen for receiving projector light from a projector facing direction includes a substrate having a plurality of features. Each of the features includes a reflective surface oriented to the projector facing direction. Each of the reflective surfaces is curved in a first direction to provide a desired horizontal viewing angle, and is curved in a second direction to provide a desired vertical viewing angle.Type: GrantFiled: October 31, 2006Date of Patent: March 3, 2009Assignee: Hewlett-Packard Development Company, L.P.Inventors: Thomas E Novet, Gilbert G Smith

Publication number: 20090035522Abstract: A pattern is imprinted into a substrate. The pattern has a number of raised regions and a number of trenches such that the raised regions are separated from one another by the trenches. The raised regions correspond to electrically isolated conductive traces to be formed on the substrate. At least an angle of deposition relative to the substrate at which an electrically conductive material is to be deposited on the substrate to form the electrically isolated conductive traces on the raised regions is determined. The angle of deposition is sufficient to ensure that adjacent raised regions remain electrically isolated. The electrically conductive material is deposited at no more than the angle of deposition relative to the substrate to form the electrically isolated conductive traces.Type: ApplicationFiled: July 31, 2007Publication date: February 5, 2009Inventors: Gilbert G. Smith, Kevin D. Almen

Patent number: 7419253Abstract: In one embodiment, a fluid flow channel includes a first part and a second part connected to and positioned downstream from the first part such that fluid can flow from the first part to the second part. The first part has opposing sidewalls, a floor extending between the sidewalls, and a ceiling extending between the sidewalls. The ceiling of the first part slopes upward in an upstream direction or the sidewalls taper in toward one another in a downstream direction, or both. The second part has opposing sidewalls and a ceiling extending between the sidewalls. The ceiling of the second part slopes upward in an upstream direction.Type: GrantFiled: February 18, 2005Date of Patent: September 2, 2008Assignee: Hewlett-Packard Development Company, L.P.Inventors: David N. Olsen, Gilbert G. Smith

Patent number: 7093930Abstract: Methods and systems for managing bubbles in a micro electro mechanical systems device are described. One exemplary system includes a fluid-feed channel configured to supply fluid to a plurality of ejection chambers, individual ejection chambers comprising a resistor configured to eject fluid from the individual ejection chamber. The system further includes a processor configured to cause an individual resistor to be energized at a first intensity sufficient to eject fluid from a respective ejection chamber, the processor further configured to cause the resistor to be energized at a second lower intensity which heats the resistor but does not cause fluid to be ejected from the respective ejection chamber, and wherein the processor can energize, at the second lower intensity level, individual resistors in a pattern designed to detach a bubble from a surface defining a portion of the fluid-feed channel.Type: GrantFiled: September 18, 2003Date of Patent: August 22, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ozgur Yildirim, Gilbert G.
