A micromirror array positioned within a laser cavity generates a patterned plurality of laser beamlets which can be homogenized and deflected by a second micromirror array onto the surface of a workpiece to create a two-dimensional pattern. Alternatively, the second micromirror array can deflect laser beamlets of unequal energy density to produce a three-dimensional pattern.

Abstract: A microwave antenna is described, capable of simultaneous maximum gain communication with N≧2 satellites in geo-stationary orbit. The orbiting satellites are positioned offset relative to each other at a specific azimuth angle(s) &phgr;. The microwave antenna has radiating elements that are divided into N groups (1a, 1b; 1a′, 1b′; 1a″, 1b″ 1c″) of radiating elements. The antenna is characterized by the fact that each of the N groups of radiating elements is organized in a plane, with the planes arranged at specific angles relative to one another corresponding to the respective azimuth offset angle of the satellite to be communicated with, such that the surface normal (FN) of the planes, once the microwave antenna is oriented, point in the direction of the respective satellites.

The blending frame is preferably located a distance Dframe from the aperture of the projector and has an optimal half frame width Wf from the axis of the lens of the projector. A camera-based feedback loop can be employed to fine-tune the optical blending by digitally altering the image source.

Abstract: A method for making accurate and precise customized corrections to the surface of an optical lens is described. An electronic correction contour is generated from a measured refractive correction for a patient, and transferred to the surface of the lens by ablation etching with one or more laser pulses. After each of the laser pulses, the refractive properties of the lens are measured and compared to the electronic contour correction derived from a patient's refractive correction. The ablation etching is terminated in localized areas where the refractive properties match the electronic correction contour. End point detection includes monitoring refractive qualities of the lens during the recontouring process, modifying the pattern through changes in the laser pulses.

Abstract: A connector assembly for removing static electricity generated in high-speed communication cable as a result of tribocharging is described. The invention is realized with a typical high-speed cable having a connector provided with a dissipative medium and at least one conductive pad. Static electricity on the jacket material of the cable induces a charge in the cable wires, which is bled to the pads via the dissipative medium. The charge on the pad is then grounded prior to or as the cable is connected to a cable jack.

Abstract: The controller 70 of the brine supply device 10 performs the PID calculation of the manipulated variable MV of the valve 14, calculates the compensated manipulated variable MV′ by compensating the manipulated value MV, and controls the operation of the valve 14 based on the compensated manipulated variable MV′. The variation &Dgr;MV of the manipulated variable MV becomes proportional to the variation &Dgr;PV of the brine supply temperature Pt1 as the operation of the valve 14 is controlled with the compensated manipulated variable MV′. This makes it possible to control temperature with a high accuracy using only one set of PID constants.

Abstract: Image templates are extracted from video images in real-time and stored in memory. Templates are selected on the basis of their ability to provide useful positional data and compared with regions of subsequent images to find the position giving the best match. From the position data a transform model is calculated. The transform model tracks the background motion in the current image to accurately determine the motion and attitude of the camera recording the current image. The transform model is confirmed by examining pre-defined image templates. Transform model data and camera sensor data are then used to insert images into the live video broadcast at the desired location in the correct perspective. Stored templates are periodically updated to purge those that no longer give valid or significant positional data. New templates extracted from recent images are used to replace the discarded templates.

Abstract: A self-inflatable mattress is formed from an open pore foam core and one or more layers of dual melt film. Initially, a layer of dual melt film is placed on top of the open pore foam block such that the side with the lower melting temperature contacts the foam core. A non-stick, heat transferable buffer layer is then placed on top of the film and heat and pressure are applied, preferably through a roller, causing the bottom surface of the film to stick to the top surface of the foam core. The edges of the top sheet are also adhesably attached to the sides of the core using a pair of heated side pressure rollers. Lastly, the cushion is inverted and a second, or bottom, sheet of dual melt film is placed on top of the foam core and attached to the bottom surface and sides in a similar manner. Finally, a valve, which may be either oral, or one way, is attached to the side of the mattress.

Abstract: A p-i-n photodiode included a heavily dopes epitaxially grown layer of semiconductor. The photodiode is comprised of heterojunctions of epitaxial material grown on an InP semiconductor substrate (12, 14). A heavily doped layer (20) is patterned on top of an InP layer (18) to define the source of p-type diffusion for the definition of the active region (22) of the p-n junction. The epitaxially grown source layer (20) may be comprised of ternary or quaternary III-V semiconductor alloys, typically InxGa1−xAs. The principle can be extended to alloy layers that are not lattice-matched to the InP substrate. The p-type dopant is typically Zn, but may also consist of other commonly used p-type dopants such as Be.
