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 method for correcting the phase and amplitude imbalance of a quadrature modulated RF signal requires that errors be induced in both amplitude, &rgr;, and in phase &phgr; in at least three different combinations in order to determine the appropriate correction value for amplitude and phase offsets &Dgr; and &thgr;e. According to a first embodiment the same &rgr; and &phgr; offsets applied in three different combinations to determine the necessary &Dgr; and &thgr;e corrections. According to a second embodiment, a fourth measurement is made in order to determine an unknown control scale factor for balance adjustments.

The distance between the UV modules is selected in such a way that the cross-sectional area of the irradiation chamber of each UV module is not more than ten times larger than the cross-sectional area of the UV module itself.

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.

Abstract: A fiber strain relief apparatus is disclosed with bend radius limiter and slack storage. The strain relief mechanism is a bend limiter drum with three lugs, a strain relief pivoting top with latch, a latch stopper handle, a compressible gasket, and a base with latch. Fiber slack is wound around the bend limiter drum. Fibers are prevented from sliding off by the lugs. A gasket compresses on to the fibers producing a strain relief action, while the slack is being stored on the drum. Unlatching the strain relief top is performed by compressing the top latch against the latch stopper. The strain relief top pivots around a living hinge producing access to the drum. Cable is coiled around the drum and the strain relief top is latched, holding the fiber against the drum. A base latch is provided allowing the device to be mounted and removed from a panel.
