  • Patent number: 7156970
    Abstract: 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.

  • Publication number: 20050247565
    Abstract: 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.

  • Patent number: 6476376
    Abstract: 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.
