Abstract: Methods and apparatus for performing addressable fusing and/or heating of a substrate undergoing xerographic processing are disclosed. The apparatus includes a fuser having an array of addressable heating elements in radiative communication with a substrate through a fuser roll or fuser belt. The array of addressable heating elements is operated to selectively heat portions of the substrate to achieve a desired effect on the substrate, such as changing its surface finish, or fusing unfused toner to the substrate. In the case of toner fusing, the array is operated such that substantially only an area covered by the unfused toner is heated. This eliminates the need for blanket fusing, and generally provides for greater flexibility in xerographically processing substrates. Apparatus and methods for performing two-sided selective fusing and/or heating are also disclosed.

Abstract: A fluidic structure includes a channel and along the channel is a series of sensing components to obtain information about objects traveling within the channel, such as droplets or other objects carried by fluid. At least one sensing component includes a set of cells of a photosensor array. The set of cells photosense a range of photon energies that emanate from objects, and include a subset of cells that photosense within subranges. A processor can receive information about objects from the sensing components and use it to obtain spectral information. The processor can perform an initial analysis using information from one set of sensing components and, based on the results, control a fluidic device in the channel, such as a gate, to retain objects, such as for concentration and more detailed analysis by other sensing components, or to purge objects from the channel.

An implementation of a vertically integrated traveling wave module is described which allows for scalability to arbitrary gel dimensions through tiling. In addition, several unique traveling wave algorithms are also described which when used in conjunction with the traveling wave grids, impart selective motion to biomolecules or other charged species.

Abstract: Various systems and techniques are disclosed for stopping, selectively controlling, and optimizing a flow of particles in a flowing stream. The systems and techniques utilize a multi-electrode assembly and various voltage waveforms applied to those electrodes. The particles flow past or near the electrode assembly and their flow is controlled by the configuration and arrangement of the electrodes and the voltage waveforms applied thereto. An additional strategy for countering particle leakage flow is also described.

Abstract: Several traveling wave grid systems are disclosed that may be used to concentrate and form highly localized regions of bio-agents or other charged species. In addition, specific detection systems are described that enable currently available detectors and sensors, including those to be developed in the future, to be used for measuring the presence and concentration of certain bio-agents or charged particles, which otherwise are present at concentrations too low to readily detect or measure.

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.

The device vibrates a region of a target surface containing the sample and collects the sample on an electrically charged pin array. The sample can be later released to a detector or other instrumentation for subsequent analysis.

Abstract: A data transmission interconnect assembly capable of transmission speeds in excess of 40 Gbps in which, for example, a line-card is detachably coupled to a backplane using flexible flat cables that are bent to provide a continuous, smooth curve between the connected boards, and connected by a connection apparatus that employs cable-to-cable interface members that are transparent to the transmitted signal waves. Microspring interface members are formed on the contact structure pressed against the cables to provide interface arrangements that are smaller than a wavelength of the transmitted signal. A connector apparatus uses a cam mechanism to align the cables, and then to press the contact structure, having the microspring interface members formed thereon, against the cables. An alterative contact structure uses anisotropic conductive film.

One method involves providing a mixture including at least one dipolar particle encapsulated in a shell and at least one shell which does not encapsulate a dipolar particle. The mixture is positioned in a spatially inhomogeneous electric or magnetic field and at least one encapsulated dipolar particle is isolated from the mixture.

Abstract: A process for forming toner particles includes aggregating the toner particles by adding an aggregating agent to a latex emulsion of resin having a colorant mixed therein, the adding being done under adding conditions of agitation and a temperature above a glass transition temperature of the resin, wherein the adding of the aggregating agent comprises first introducing at least about 40% by weight of a total amount of aggregating agent to be added at a rapid introduction rate and subsequently adding a remaining portion of the aggregating agent at a continuous addition rate slower than the rapid introduction rate. The particles are subsequently cooled to a temperature below the glass transition temperature of the resin when particles have been grown to the desired size.
