Abstract: Thermal sensors for calorimetry can include vanadium oxide, heavily p-doped amorphous silicon, or other materials with high temperature coefficients of resistivity. Such thermal sensors can have low noise equivalent temperature difference (NETD). For example, a thermal sensor with NETD no greater than 100 ?K over a bandwidth range of approximately 3 Hz or more can include a thermistor including vanadium oxide sputtered at room temperature under conditions that yield primarily V2O5; more specifically, the NETD can be no greater than 35 ?K, or even 10 ?K over a bandwidth range of approximately 3 Hz or more. If a low noise thermal sensor has NETD no greater than 50 ?K over such a bandwidth range, a low noise output circuitry connected to its thermistor can provide an electrical output signal that includes information about input thermal signal peaks with amplitude of approximately 100 ?K.

The IC die/substrate assembly further includes at least one coupling that facilitates maintaining an IC die/substrate gap definition between the IC die and the substrate.

Abstract: A method is disclosed for high-throughput screening assay sample preparation and testing for the identification of binding between drug targets and library compounds, for use with a calorimetric device measuring the enthalpy of reaction for the binding. The method includes mixing a library compound with a specified solvent and mixing a target compound solution with a second specified solvent on a calorimetric device. The library compound/solvent is merged with the target compound/solvent solution and the library compound/solvent solution is also merged with a third solvent solution on the calorimetric device. The heats of reaction are detected for both merged solutions and are compared.

Abstract: A measurement operation, such as a calorimetry measurement, is performed using a measurement array and a replaceable passivation membrane (e.g., a parylene membrane). The passivation membrane is used to cover the measurement array to provide temporary electrical and chemical passivation, while still allowing measurement of the parameter of interest (e.g., temperature, in a calorimetry measurement). By only replacing the membrane instead of the entire measurement array between measurement operations, the cost of the measurements can be significantly reduced over conventional methods. The passivation membrane can be mounted on a frame to simplify handling of the membrane.

Abstract: An improved microvalve is described. The microvalve is formed such that the walls of the microvalve are formed from a gel material. Typically, the microvalve includes open flow paths, often holes, through a gel layer. An electric field is applied in regions where fluid flow is undesirable. The electric field compresses the gel closing the flow path thereby preventing further fluid flow.

Abstract: A structure and method of using a reusable master printing plate is described. In one embodiment, the viscosity of an electrorheological fluid is adjusted using an electric field to control its flow and create the desired relief pattern in a flexible printed surface. After creating the relief pattern, the pattern is fixed and used for printing. After completion of printing, the relief pattern is removed from the master printing plate and the printing plate may be reused by applying a new pattern.

Abstract: A structure and method of using a reusable master printing plate is described. In one embodiment, the method uses an electric field to control a series of microvalves. The microvalves control a fluid flow that raises or lowers selected regions on a flexible printing surface to create a desired relief pattern. After creating the relief pattern, the pattern is fixed and used for printing. After completion of printing, the relief pattern is removed from the master printing plate and the printing plate may be reused by applying a new pattern.

Abstract: A method and apparatus for improving a network is described. The network uses the energy from a vehicle battery or vehicle generator to power an intermediate transmitter device that receives the signal from a portable wireless device and retransmits the information in the signal to a base station. The intermediate transmitter device also receives information from the base station and retransmits the information to the portable wireless device. The described system expands the areas in which a wireless device may be used.

Abstract: A MEMS system including a fixed electrode and a suspended moveable electrode that is controllable over a wide range of motion. In traditional systems where an fixed electrode is positioned under the moveable electrode, the range of motion is limited because the support structure supporting the moveable electrode becomes unstable when the moveable electrode moves too close to the fixed electrode. By repositioning the fixed electrode from being directly underneath the moving electrode, a much wider range of controllable motion is achievable. Wide ranges of controllable motion are particularly important in optical switching applications.

Abstract: A system for printing is described. The system uses at least one cantilever, and more typically a plurality of cantilever to transfer charge, either to or from a dielectric surface. The resulting charge distribution represents an image. Toner deposited over the dielectric surface is attracted to the charged portions of the dielectric. Thus the toner also forms the image. The toner image is then transferred and affixed to a printing surface.

Abstract: Mechanical and/or structural devices are formed using electroplating techniques in conjunction with sacrificial materials that can also be formed using electroplated techniques. This can produce devices that are attached at only selected points to a substrate and/or structures having enclosed cavities on or above a working substrate. A particularly relevant use of such structure forming techniques is in the fabrication of an ink jet manifold and nozzle structure for use in an ink jet print head, particularly a MEMS-based ink jet print head.

Abstract: A system for depositing a material is described. The system uses at least one cantilever, and more typically a plurality of cantilever to transfer small amounts of material from a source of material to a substrate surface. One application for the system is a printing system in which the material is an ink and the substrate is a sheet of paper. By repeating this process, the cantilever places many units of ink to form the pixels in an image.

Abstract: A microlens structure is mounted directly onto the upper surface of a packaged VCSEL device and positioned to locate microlenses directly over corresponding VCSEL elements. The microlens structure includes a block-like pedestal having a lower surface that faces the upper surface of the VSCEL device. The microlenses are formed in a central region of the lower surface, and several legs (stand-offs) extend from peripheral edges of the lower surface. During assembly, the VCSEL device is positioned under the microlens structure such that each microlens is aligned over its corresponding VCSEL element, and then raised until the legs contact the upper surface of the VCSEL device. The legs serve to self-align the microlenses to the VCSEL device, and are sized to maintain an optimal distance between the microlenses and the VCSEL elements. The pedestal is attached to a carrier plate that is secured to an IC package housing the VCSEL device.

Abstract: A system for transporting and selectively sorting particles includes a first wall and a traveling wave grid extending along the first wall. The system includes a second wall having a passage extending therethrough and a gate operatively associated with the passage. A controller is adapted to output a multi-phase electrical signal. The controller is in communication with the traveling wave grid and the gate. A method of using the system is also provided.

Abstract: An out-of-plane micro-structure which can be used for on-chip integration of high-Q inductors and transformers places the magnetic field direction parallel to the substrate plane without requiring high aspect ratio processing. The photolithographically patterned coil structure includes an elastic member having an intrinsic stress profile. The intrinsic stress profile biases a free portion away from the substrate forming a loop winding. An anchor portion remains fixed to the substrate. The free portion end becomes a second anchor portion which may be connected to the substrate via soldering or plating. A series of individual coil structures can be joined via their anchor portions to form inductors and transformers.

Abstract: A display apparatus includes an emissive screen having luminescent pixels that are addressed solely by a laser addressing system. Each pixel includes a luminescent region located next to a photocathode. When struck by the laser beam, free electrons are created that are accelerated by an applied high voltage field from the photocathode to the luminescent region, thereby causing the luminescent region to emit visible light with a brightness (energy) that is substantially higher than the energy of the addressing beam. Apertures are optionally provided in hexagonal luminescent regions to relax beam-scanning requirements. Optional millichannel plates (crude versions of 2nd generation night vision system Microchannel plates) are provided to enhance photon multiplication. A position sensitive device is implemented using the photocathode or photoanode (luminescent) material to facilitate the scanning and modulating process.
