Abstract: The movement and mixing of microdroplets through microchannels is described employing microscale devices, comprising microdroplet transport channels, reaction regions, electrophoresis modules, and radiation detectors. The discrete droplets are differentially heated and propelled through etched channels. Electronic components are fabricated on the same substrate material, allowing sensors and controlling circuitry to be incorporated in the same device.

Abstract: The invention is characterized in that it comprises a toolpath generating routine and system for generating a plurality of control points directly from image data representing an image to be engraved. The control points are used to generate a toolpath which, in turn, will be used to energize an engraving head such that a tool or stylus will engrave a pattern of engraved areas in response to the toolpath. An engraving system and method for engraving at least one engraved area is shown having an engraving head tuner for tuning an engraving head such that the frequency characteristic of the engraving head defines a substantially constant gain for frequencies less than a predetermined frequency.

Abstract: An undersampling digital testability circuit 20 includes a bus 15, a data capture array 22 and a divider circuit 18. Divider circuit 18 provides an enablement signal to data capture array 22 that undersamples data travelling along the bus 15 at high data rates thereby effectively testing the integrity of high data rate transfers without the disadvantages of prior art test methodologies.

Abstract: A device, and process, for continuously separating dissolved solutes and suspended particles from a multicomponent fluid phase in a magnetically stabilized fluidized bed (MSFB). The process is of the type wherein a solid resin and a liquid buffer move countercurrent to each other in the bed. In steady state operation, a time invariant pH gradient will form in the bed and remain spatially fixed. Other condition variables, such as temperature, can be used to form a time invariant gradient provided that equilibrium partition between the solid and liquid phases is a function of the condition variable.

Abstract: An apparatus measures a repetitive signal in a coherent manner, including a signal generating circuit to output the repetitive signal in accordance with first clock signals which are generated by a first clock circuit. A sampling circuit samples the repetitive signal in accordance with second clock signals to output a sampled signal, the second dock signals are output by a second clock circuit. An output circuit stores the sampled signals and outputs a reconstructed signal based on said sampled signal.

Abstract: The present invention includes a method of eliminating interference from an undersettled electrical signal, the undersettled electrical signal including a test signal at a known frequency. One embodiment of the present invention includes a method comprising the steps of providing a digitized version of the undersettled electrical signal (at 46); generating a frequency spectrum of the digitized version of the undersettled electrical signal (at 56); spectrally interpolating the frequency spectrum to generate an interference signal frequency spectrum (at 65); and subtracting the interference signal frequency spectrum (at 65) from the undersettled signal frequency spectrum (at 56) generating a settled signal spectrum (at 75).

Abstract: A process for manufacturing a metallized part comprises the following steps. A part is provided made from a substrate material selected from the group consisting of thermoplastic urethane (TPU), TPU alloys, polyester alloys, nylon, thermoplastic olefins (TPO) and aluminum. A single protective layer (combined primer/basecoat) is spray deposited, flashed and cured over the substrate. Over the combined primer/basecoat layer, a layer of corrosion prone metal is vacuum deposited to form a discontinuous film covering the combined primer/basecoat layer. A layer of clear resinous protective dielectric topcoat is spray deposited and cured to completely cover the layer of vacuum deposited corrosion prone metal material and fill channels formed in the discontinuous film layer.
