Abstract: A method for fabricating a stripe color filter for the input of an image intensifier having a color-interpretive CCD output includes ascertaining CCD subpixel-to input coordinate correlation by test illumination with a positioning laser having low power. Based upon the correlation data assembled, light sensitive filter media, such as color tinted photoresist is exposed at those locations corresponding to like-color CCD subpixels. The media is then developed to form filter media. Subsequent coatings of photoresist of the next color are applied and exposed etc.

Abstract: A fiber optic viewing device has in a first embodiment, a color-preserving image intensifier positioned at the viewing end thereof. In a second embodiment, an input light source is sequentially modulated through a cycle of wavelength sets. The resulting image is intensified and recolored by an output recoloring filter which is synchronized with the input light modulation. In yet another embodiment, a set of red, green and blue LEDs are sequentially modulated by a controller to provide input light. A CCD camera receives the resultant intensified image and converts it to video format. A video processor stores frames during a cycle of modulation and then integrates the frames for viewing in full color.

Abstract: An image intensifier device for producing a color output image includes in a proximity focused intensifier tube, an RGB color filter matrix screen printed upon a glass wafer which is laminated to the input faceplate of the tube and sandwiched between the faceplate and the photocathode. The RGB matrix filters incident light into RGB components which are amplified by the tube. The output image is colorized in a first embodiment by passing white light fluorescing from a phosphor layer through an RGB output filter matrix which is functionally aligned in an operating tube with the input matrix. In a second embodiment, a UV emanating phosphor layer excites an RGB matrix of secondary phosphors. In a third embodiment, IR filters are included in the RGB input matrix and a narrow band output filter is assigned to represent IR information in the RGB output matrix. In a fourth embodiment a plurality of RGB phosphors replace the phosphor layer of the previous embodiments and directly fluoresce color information.

Abstract: A color preserving image intensifier having synchronously reciprocating input and output multi-segmented, multi-color filter slides. To compensate for differences in exposure time of the segments of the filters arising from varying reciprocation velocity due, e.g. to sinusoidal motion, either the intensity of the output image is variably filtered or the intensifier gain is varied. In one embodiment, polarizing filters rotated in synchronicity with the reciprocation of the color preserving filters vary image intensity. In another embodiment, intensifier gain is varied based upon a velocity indicator.

Abstract: A process and apparatus for providing simulation and modeling and control which permits user feedback for purposes of implementing design and process optimization for composite or powder compact materials. Control is achieved through a dual feedback and feedforward hierarchical control scheme employing an interactive modeling system for providing the feedforward control data and a PID control loop for the feedback control. Modeling is based upon constitutive equations which form the basis of modeling solutions derived from the micromechanical relationships inherent in the consolidated materials. The system is implemented in an FEM software platform such that a graphics based visualization in three dimensional form can be provided to the user.

The method comprises the following steps: selling a first plurality of lottery tickets for a lotto style lottery game in which prizes are paid out at both the jackpot and sub-jackpot levels; drawing a first winning combination; and selling a second plurality of tickets for a subsequent game such that said first plurality of lottery tickets may be reutilized for the jackpot prize level of a subsequent drawing.

Abstract: A differential electronic imaging system has a diode array camera and a plurality of A/D processing circuits connected to the respective diode pixel elements in parallel. The A/D processing circuits are operated in successive frame periods including a first partial period for processing an object-plus-FBP image and a second partial period for processing a fixed background pattern (FBP) image, in order to derive digital differential image data representing the object image alone. The use of parallel processing eliminates the bottleneck of conventional serial processing of the pixels of the image plane, and permits better sensitivity and image resolution. The use of the A/D processing circuits for direct conversion of the object-plus-FBP image minus the FBP image in each frame period eliminates readout noise, high frequency noise errors, FBP drift errors, and storage requirements for the FBP image.

Abstract: A color image intensifier device combines an image intensifier tube providing monochrome output with input and output color members each having a plurality of color portions for passing respective different light frequencies. The input color member filters the incoming light to the tube for each light spectrum band in timed succession, and the monochrome output of the tube passes through the output color menber to produce a corresponding color component output. The color component outputs are perceived by the eye as a complete color image if the timed modulation of the incoming image is above the threshold level for flicker. In a mechanical version, the color members are input and output color wheels rotated in tandem at the input and output ends of the image intensifier tube. The filter members may also be arranged in the form of linearly reciprocating slides or planes movable in two dimensions. The color members can also be stationary filters which change color by electronic control.

The isolator includes an inflatable bag of flexible material through which filtered air is circulated. For use in surgery, a portion of the lower side is made of an elastic surgical drape material to allow a body member upon which a surgical procedure is to be performed to be pulled into the work space of the bag. A portion of the top side of the bag is made of a relatively stiff, optically transparent, material through which the surgeon or the assembly worker can view the work area. A plurality of open-ended sleeves are attached to the bag through which the hands and arms of the surgeon and his assistants or the worker can extend into the work space.

Abstract: Included are the title phosphorate compounds, and a process to prepare them comprising contacting a carbylphosphorate mono acid halide with a carbyloxide.

Abstract: An arrangement for processing video signals, the video signals having the form of digitally encoded samples and being arranged to produce a television picture by line and field sequential scanning includes a frame store, a write address generator and a read address generator. Input video samples are fed from an input to an interpolator for writing into the store.When a television picture is to be rotated and the rotation is effected by the sequence of write addresses to the store a situation can arise where there is no information available for writing into certain store locations. This results in holes appearing in the output signal where no picture related information is present. A hole detector is provided at the store output and controls an interpolator which inserts information derived from adjacent picture samples into the hole.
