Patent number: 8919939Abstract: Approaches to remove objects from ink in an ink jet printer are described. An object separator for an ink jet printer includes one or more inlets configured to allow passage of ink that includes objects such as bubbles and particles into the object separator. The object separator has a number of stacked plates. Some of the plates have curved channels which are connected through other plates that include vias. The plates are arranged to form at least one cyclonic flow generator, the cyclonic flow generator configured to focus the objects into one or more focused flow streams. The object separator includes one or more object outlets that allow objects to exit the object separator and at least one ink outlet that allows the ink to exit the object separator.Type: GrantFiled: August 13, 2013Date of Patent: December 30, 2014Assignee: Palo Alto Research Center IncorporatedInventors: John S.

Patent number: 8293213Abstract: A method and system for affecting a thrombus after ischemic stroke. The method may include injecting a plurality of magnetic particles into a bloodstream and moving or distorting a thrombus formed or lodged in the bloodstream using a magnetic force to manipulate the magnetic particles. The method may include conjugating ferromagnetic particles, paramagnetic particles, or superparamagnetic particles to a thrombus-specific attachment agent such as an anti-fibrin antibody, and injecting the conjugated particles into the bloodstream. Thereafter, the thrombus may be agitated, broken apart, or dissolved using a magnetic field to exert a magnetic force on the conjugated particles. The method may also include injecting a thrombolytic agent into the bloodstream to interact with and further dissolve the thrombus.Type: GrantFiled: March 12, 2009Date of Patent: October 23, 2012Assignee: Palo Alto Research Center IncorporatedInventors: David Eric Schwartz, Scott A.

Patent number: 8290408Abstract: An improved method and system for non-contact powder image development are provided. The present technique implements a 5-stage jumping development cycle where the initial stage is a momentary over-voltage condition to release the majority of the toner on a donor substrate and the final stage includes the implementation of a decelerating potential to minimize return impact on the donor and therefore toner abuse. It also uses a routine to directly determine improved (e.g. up to optimal) waveform amplitudes and pulse widths based on toner size and q/m, guided by physical insight.Type: GrantFiled: March 14, 2008Date of Patent: October 16, 2012Assignees: Xerox Corporation, Palo Alto Research Center IncorporatedInventors: Meng H.

Publication number: 20120200630Abstract: Bubble mitigation approaches for phase change ink involve creating a thermal gradient along an ink flow path of an ink jet printer during a time that the ink is undergoing a phase change. The thermal gradient causes one portion of the ink in the ink flow path to be in liquid phase while another portion of the ink is in solid phase. The thermal gradient allows the liquid ink to move along the ink flow path to fill in voids and/or to push out air pockets in the portion of the ink that is still solid. The bubble mitigation process may be implemented during a start-up operation when the ink is transitioning from a solid phase to a liquid phase and/or during a power down operation when the ink is transitioning from a liquid phase to a solid phase.Type: ApplicationFiled: February 7, 2011Publication date: August 9, 2012Applicant: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Scott J.

Publication number: 20110155311Abstract: An imageable medium includes a reusable substrate and a removable surface layer semi-permanently bonded to a major surface of the substrate, the reusable substrate comprising an opaque backing to the removable surface layer and the removable surface layer comprising an imageable surface. A use indicator can be incorporated into the imageable medium, and correspond to at least one of the reusable substrate and removable surface layer. The use indicator can be an RFID chip. A method of imaging includes preparing an imageable medium by semi-permanently bonding an imageable layer to a reusable substrate, the reusable substrate providing an opaque backing to the imageable layer; imaging the imageable layer of the imageable medium; removing an imaged layer upon completion of use of the imaged medium; and repeatedly imaging a revealed imageable layer and removing the imaged layer.Type: ApplicationFiled: December 28, 2009Publication date: June 30, 2011Applicant: Palo Alto Research Center IncorporatedInventors: Lee ACKERSON, Eric J.

Patent number: 7756801Abstract: Various implementations provide for a task assignment method that describes a spatial computing application by providing an abstract task graph (ATaG) wherein the abstract task graph specifies the behavior of the application without reference to the number, placement and connectivity of the nodes performing the application and the tasks are automatically mapped to the network. The ATaG specifies a set of tasks, a set of data objects and a set of channels, including various constraints and preferences on where in the network tasks may be performed, how data is moved between locations and the data required at various locations. Moreover, various implementations provide for a task assignment system which maps the abstract tasks and channels to specific nodes and communication links, either at the time of the construction of the system or throughout the time of its operation.Type: GrantFiled: November 15, 2004Date of Patent: July 13, 2010Assignee: Palo Alto Research Center IncorporatedInventors: James E Reich, Daniel L Larner, Amol B Bakshi

Patent number: 7495550Abstract: This disclosure introduces a system which generates a visual, audio, and/or tactile warning to a driver of a lead vehicle when a possible rear-end collision is detected, based on the approach of a second vehicle from a rear direction. The system may also generate a warning signal (such as quick blinking red brake light, or an array of multi-color lights) directed to the approaching vehicle when it is determined to be approaching at an unsafe speed. The system may include one or more of: approaching-vehicle-sensors mounted on the back end of the lead vehicle, a computer processing system, a set of warning lights, a set of speakers within the lead vehicle, and an antenna and transmitter/receiver for communicating with systems of other vehicles. This system may include a connection to the existing taillight system and other existing systems in the lead vehicle.Type: GrantFiled: December 28, 2005Date of Patent: February 24, 2009Assignee: Palo Alto Research Center IncorporatedInventors: Qingfeng Huang, James E.

The physical device consists of an effector platform suspended by two suspension wires whose lengths are adjusted by motorized spindles mounted above and on either side of the board surface. The position of the effector platform is adjusted by winding and unwinding the wires. Electrical power is supplied to the effector platform through the suspension wires or through an on-board battery. Control of a pen and/or other apparatus on the effector platform is achieved through modulation of the power voltage. A further component of this invention is electronic and computational apparatus for controlling the device, which may include automatic visual interpretation and feedback from a video camera viewing the board and printer.Type: GrantFiled: November 29, 1999Date of Patent: April 9, 2002Assignee: Xerox CorporationInventors: Eric Saund, Thomas M.
