Patent number: 7945346Abstract: A configurable self-identifying workpiece transport system is described for moving an associated workpiece relative to a plurality of associated workpiece functional units selectively performing operations on the associated workpiece. The transport system includes a plurality of transport modules and a control unit. The plurality of transport modules are disposed in selected positions relative to the associated workpiece functional units, and each of the plurality of transport modules stores identification data and functionality data specific to the transport module. The control unit includes an automatic identification system in communication with each of the plurality of transport modules for retrieving the identification data and the functionality data from each of the plurality of transport modules and generating an itinerary for moving the associated workpiece relative to the workpiece functional units.Type: GrantFiled: December 14, 2006Date of Patent: May 17, 2011Assignee: Palo Alto Research Center IncorporatedInventors: David K. Biegelsen, Bryan Preas, David G. Duff, Markus P. J. Fromherz, Craig Eldershaw, Lee Ackerson

Patent number: 7156970Abstract: Various traveling wave grids and electrophoretic systems, and electrode assemblies using such grids, are disclosed. A configuration in which a voltage potential is used to load a biomolecule sample against a grid is disclosed. A unique strategy of using multiple, reconfigurable grids in such systems is also described. The strategy involves initially conducting a broad protein separation and then selectively tailoring one or more grids, and conducting one or more secondary processing operations. Related strategies and specific methods are additionally disclosed for separating samples of biomolecules and components thereof using the noted systems, assemblies, and grids.Type: GrantFiled: June 12, 2003Date of Patent: January 2, 2007Assignee: Palo Alto Research Center IncorporatedInventors: Meng H.

Publication number: 20050247565Abstract: A portable apparatus for extracting and concentrating bioagents within a fluid medium includes a container with sample solution inlet port and traveling wave grids patterned on surfaces of the container. The traveling wave grids cause bioagents to migrate to a specified surface within the container and then to an extraction port. The traveling wave grids include a substrate, across which extend a collection of closely spaced and parallel electrically conductive electrodes, and a collection of buses providing electrical communication with the collection of conductive electrodes. A voltage controller provides a multiphase electrical signal to the collection of buses and electrodes of the traveling wave grids.Type: ApplicationFiled: May 4, 2004Publication date: November 10, 2005Inventors: H. Hsieh, Meng Lean, Bryan Preas, Armin Volkel

Patent number: 6476376Abstract: Apparatus and method for sensing the position, size, shape and location orientation of one or more objects in two dimensions. The position sensor uses arrays of light sensors mounted on a substrate. When an object passes in proximity to the light sensors light energy from a plurality of light sources is either reflected from the object to the light sensors, or is emitted directly to the light sensors. The light energy is then converted to individual signals and transmitted through circuit traces in a printed circuit board to a local controller. The information may then be processed to determine the size, position, shape and location orientation of an object.Type: GrantFiled: January 16, 2002Date of Patent: November 5, 2002Assignee: Xerox CorporationInventors: David K. Biegelsen, Bryan Preas, Lars Erik Swartz, Warren B. Jackson
