Abstract: A device for imaging a relief object without illuminating a platen is disclosed. The device includes a single electrode electroluminescent device, which may be inorganic or organic, and a current source. The current source is coupled to the single electrode of the electroluminescent device and to the relief object to be imaged. The valleys and ridges of the relief object couple current to the electroluminescent device at different magnitudes which causes the electroluminescent device to generate light at different intensities that correspond to the ridges and valleys of the relief object. The generated light forms an image of the relief object which may be focused by optical elements onto a sensor array for capture and image processing. In another embodiment of the invention, a one-to-one sensor array is located proximate the electroluminescent device to capture the image.

Abstract: A system and method for using a relief object image generator for cursor control, computer access control, and operational parameter control is disclosed. The system includes a relief object image generator, a sensor array, an image processor, and a memory. The relief object image generator generates images of relief objects, such as fingerprints, brought in proximity of the exposed surface of the image generator. The image processor receives the image from the sensor array, processes the image, and compares the resulting descriptive information to stored information corresponding to authorized users. If a match is found, the user is granted access to the computer. The image processor may also process the image to determine image movement or the image's presence or absence. Detected movement is used to generate directional signals while the presence and abserice of the image is used to generate highlight and select signals.

Abstract: A flat display for providing high contrast, low-artifact enlarged optical images. The flat panel display comprises a pixelated input imaging device, a first array of optical waveguides including a bias cut, a first light redirecting layer, a second array of optical waveguides also including a bias cut, and a second light redirecting layer. The first and second arrays of optical waveguides enlarge an input image in first and second directions, respectively. Moiré fringe effects are minimized by one or more of: forming the waveguides of the first and second arrays such that the ratio between the waveguide size of the first array to the waveguide size of the second array is at least 1.25; forming a random distribution of waveguides sizes in the first and second arrays; and tilting the second array with respect to the first array. A ratio between the major dimension of the pixels of the input imaging device and the major equivalent dimension of waveguides is between about 1.20 to 4.0.

Abstract: A method of cleaning water mains includes isolating a section of water main. Compressed air is then used to blow out the water within the water main. The water main is actually cleaned by interspersing slugs of water between sections of compressed air. The compressed air includes atomized chlorine and a polyphosphate inhibitor. Once the water main has been cleaned, the flow of water is returned to the isolated section.

Abstract: A large scale LED exposure array and system for printers, and unique methods of inputting data to and operating such an array, are disclosed. The array can be loaded and refreshed with data information at rates compatible with high speed printing, and forms part of an electronic image forming and handling system which can load an refresh an exposure array at variable speeds of at least 100 to 300 ft./min. The system includes compensation for differences in illuminating capability of individual LEDs in a large array, by introducing modifications in LED on-time which are centered with respect to the incremental area of the photoreceptor on which a pixel is to be formed, and to compensate for changes in pixel exposure time with increase in speed of the photoreceptor.

Abstract: A scanned video display system in which a stress wave propagating medium forms a viewing plane and scanning is accomplished in a first scanning direction by stress waves propagated along the medium, while scanning in a second scanning direction is accomplished by emitting light along a scan line in the second direction. The light emitted along the scan line in the second direction is modulated in intensity by a video signal and is incident upon each of the stress waves over the extent of the viewing plane so as to produce a video modulated beam of light scanned in the two dimensions or directions of the viewing plane. In one embodiment, the emitted light is polarized in a first direction and passes through the stress wave propagating medium. The light is again polarized after passing through the medium but in a direction orthogonal to the first direction.
