Title: Method and apparatus for determining an algebraic solution to gps terrestrial hybrid location system equations
Inventor: FERNANDEZ-CORBATON IVAN J
IPC: G01S19/12
Filed: 2000-12-07
Abstract: A method and apparatus for use in a hybrid position location system. The method and apparatus combines measure-ments from Global Positioning System (GPS) and terrestrial transceiver stations to compute the location of a device. An algebraic solution to hybrid position location system equations is output from the method and apparatus. The method and apparatus determines the position of a device using a non-iterative method, as against the use of a conventional iterative least mean square method. The method of the present invention can be used to solve the location system equations in scenarios where a non-iterative solution is desirable. In certain scenarios, the location system equations may have two possible solutions. An iterative method would converge on one of the solutions, without any indication of the existence of the other ambiguous solution. Moreover, the iterative method may converge on the incorrect of the two ambiguous solutions. Use of the presently disclosed method and apparatus yields both the ambiguous solutios. The disclosed method may be followed up with iterative methods, using the solutions from the algebraic method as initial estimates of the device location for the iterative method. A  different process can then select the correct solution. Thus, the algebraic method can be used to detect the existence of ambiguous solutions, and to find both solutions.

Title: Determining minimum energy pulse characteristics in an ink jet print head
Inventor: CORNELL ROBERT WILSON
IPC: B41J2/14
Filed: 2001-08-03
Abstract: A system provides an optimum energy pulse to a resistive heating element (34) in an ink jet print head (10). The optimum energy pulse provides an optimal energy density at a surface of the heating element (34) to cause optimal nucleation of ink adjacent the surface of the heating element (34). The system includes storing in memory (26) values related to heating element dimensions, heating element electrical characteristics, and ink characteristics. Also stored in memory are expressions that provide mathematical relationships between the heating element dimensional values, the heating element electrical values, the ink characteristics, and the amplitude and duration of the optimum energy pulse. The system also includes retrieving from memory the store values and expressions, and determining, based on the expressions, the amplitude and duration of the optimum energy pulse. The system further generates the optimum energy pulse based on the determined amplitude and duration, and provides the optimum energy pulse to the heating element (34). The energy density provided by the optimum energy pulse is large enough to cause the ink near the heating element to form a bubble and a droplet, but not so large that energy is wasted which cannot be transferred into the ink after the bubble is formed.

Title: Three-dimensional color television system adapted for depth separation by image focal length
Inventor: HORSLEY PETER BROWN
IPC: H04N13/00
Filed: 2003-02-06
Abstract: In a three-dimensional color television system, a three-dimensional effect is usually created by processing a pair of stereoscopic images. In the current invention only one focussed image is used. The three-dimensional effect is achieved by recording the various focal lengths of rays from the original picture elements after the rays have passed through the optical lens of the camera. Within an evacuated tube, a thin photo-sensitive dielectric plate is mechanically reciprocated through the range of focal depths in the image on which the focussed illuminated picture elements generate electric charges which are then sequentially scanned and recorded electronically. At the television receiving set, a dielectric plate coated with fine fluorescent elements adapted to fluoresce in the primary colors is mechanically reciprocated in synchronization with the sequence of picture elements transmitted electronically from the camera. The range of focal depths in the image is then expanded to recreate the original three-dimensional scene by a picture tube fitted with an optical lens or fresnel lens.

Filed: 2001-10-08
Abstract: The invention concerns a guided wave spatial filter (300) for receiving inpu t radiation and outputting corresponding filtered output radiation, the filter  comprising first and second waveguide sections (30, L3, L5) connected in series, the sections: (a) mutually matched for transmitting fundamental mode  radiation components present in the input radiation therethrough to provide the output radiation; and (b) mutually mismatched for hindering higher-order  mode radiation components present in the input radiation from propagating therethrough and contributing to the output radiation. The spatial filter (300) is implemented using rib waveguides (30) for the sections with associated relatively deeply and relatively shallowly etched structures (20,  310, 320) for imparting to the sections their radiation mode filtration characteristics. The spatial filter according to the invention can be incorporated into optical splitters and optical modulators to enhance their performance and desensitise them to higher-order mode radiation injected thereinto.

Filed: 2001-11-05
Abstract: A device is provided for winding paper in which the paper web running is supported by a reel drum and wound onto exchangeable reel shafts in contact with the reel drum in order to form rolls of paper. The device applies a heated adhesive agent on the web and/or on the reel shaft onto which the web is to be wound. A spray rack is mounted on the stand of the reel-up, upstream of the reel drum and extending transversely to the machine direction, or alternatively, is mounted in various other locations of the reel-up. A hopper with a heater heats the heated adhesive agent to temporarily lower its viscosity and stickness for smooth and even spraying. The series of nozzles are mounted on the rack spaced across the width of the web to spread spray jets of liquid containing said heated adhesive onto the web and/or the reel shaft. The adhesive area thus is disposed between the web and the empty reel shaft so as to facilitate initiating the winding process.
