摘要： A tunable optical cavity can be tuned by relative movement between two reflection surfaces, such as by deforming elastomer spacers connected between mirrors or other light-reflective components that include the reflection surfaces. The optical cavity structure includes an analyte region in its light-transmissive region, and presence of analyte in the analyte region affects output light when the optical cavity is tuned to a set of positions. Electrodes that cause deformation of the spacers can also be used to capacitively sense the distance between them. Control circuitry that provides tuning signals can cause continuous movement across a range of positions, allowing continuous photosensing of analyte-affected output light by a detector.

摘要： In the case of printing at high addressability, where the cell size is smaller than the spot size, an image can be decimated in a manner that will limit the large accumulation of printed material. The proper decimation of the image will depend on the spot size, the physics of drop coalescence and the addressability during printing. A simple method of using concentric decimation is disclosed herein to enable this process.

摘要： A method of printing spots with high spot placement accuracy using print heads with random/unevenly spaced ejector locations and coarse alignment of the multiple print heads. This is performed by accurately determining the spot positions from all the print heads using a vision system and printing at high addressability. The spot placement accuracy will be determined by the addressability as long as the ejected drop position is reproducible and other system errors are negligible.

摘要： Layered metal structures are patterned to form a surface with some locations having an alloy along the top surface at some locations and the original top metal layer at other locations along the surface. The alloy and original top metal layer can be selected to have differential etching properties such that the pattern of the alloy or original metal can be selectively etched to form a patterned metal interconnect. In general, the patterning is performed by localized heating that drives formation of the alloy at the heated locations. The metal patterning can be useful for solar cell applications as well as for electronics applications, such as display applications.

摘要： An inhomogeneous optical cavity is tuned by changing its shape, such as by changing reflection surface positions to change tilt angle, thickness, or both. Deformable components such as elastomer spacers can be connected so that, when deformed, they change relative positions of structures with light-reflective components such as mirrors, changing cavity shape. Electrodes can cause deformation, such as electrostatically, electromagnetically, or piezoelectrically, and can also be used to measure thicknesses of the cavity. The cavity can be tuned, for example, across a continuous spectrum, to a specific wavelength band, to a shape that increases or decreases the number of modes it has, to a series of transmission ranges each suitable for a respective light source, with a modulation that allows lock-in with photosensing for greater sensitivity, and so forth. The optical cavity can be a linear variable filter fabricated on the photosensitive surface of a photosensing component such as a photosensor array or a position-sensitive detector.

摘要： A domino SRAM array restore pulse generation system launches the word decode line by the same local clock as the restore pulse, thus eliminating any race issues with the word line select. This system allows the global bit select (or column select) to have fast activation by releasing the reset signal (with the earliest arriving array clock, ckl), while guaranteeing almost perfect tracking with the bit decode system. This allows for the widest possible write window; earliest release of the pre-charge in the global column select, and resetting only after the bit decode system is deactivated.

摘要： An SRAM design evaluation circuit topology has the gates of the SRAM cell pass Gate Field Effect Transistors (FETs) connected to the cross-coupled gates of the inverter pair of the SRAM cell. This evaluation circuit typology is used in a full cell implementation. A series of full cells are interconnected one to another in a loop to form a ring oscillator. The output of the ring is frequency divided and measured to study the read and write behavior of the cell design. Similarly, half-cells, with the gates of their pass gates grounded, are interconnected one to another to form a ring oscillator, the output of which is frequency divided and measured to help isolate pass gate impact on memory function. The modified SRAM cell topology, connected as a ring oscillator in hardware, can be used to fully characterize an SRAM cell design, without the use of peripheral read/write circuitry.

摘要： A beam position control system controls a position of a beam directed from a beam source. The beam position control system includes a beam position sensing system that generates one or more satellite beams which are used to determine the position of a main beam. A beam offset computation block determines a relative position of the main beam with respect to a desired main beam position and provides beam offset information to a controller that generates a compensation signal used to adjust the main beam position to the desired main beam position via a beam actuation system.
