Patent number: 6741744Abstract: The invention features a method wherein a recognition environment utilizes pseudo-English as a programming language to extract simple and complex objects with image-and/or map-data as inputs. Based on this human/computer interface in which pseudo-English is a programming language, the object-recognition system has three major logic modules: (1) an input data module; (2) an information-processing module, coupled with the above-noted human computer interface (HCI) module; and (3) an output module that has a feedback mechanism back to the main information-processing and the input-data module. A physical phenomenon (i.e., one that is visible, audible, tactile, etc.) is analyzed by the information-processing module to determine whether it is susceptible to description or articulation. If not, the phenomenon is matched or compared, via the output module, to a known articulatable, physical-phenomenon model and recognizable features are extracted.Type: GrantFiled: April 17, 1999Date of Patent: May 25, 2004Inventor: Shin-yi Hsu

Patent number: 6718465Abstract: A reconfigurable processor architecture based on unique square recursive order decomposition of partial product matrices is described. This architecture can be easily reconfigured by taking advantage of the locality of data that is produced by the square recursive ordering to compute the inner products of input arrays with four or more options. Each input array may contain sixty-four 8-bit items or sixteen 16-bit items or four 32-bit items or one 64-bit item, with items in either 2's-complement or unsigned form. The processor can be pipelined to output an inner product in one machine cycle, and to complete an inner product evaluation in two to four cycles, which is particularly attractive to high-speed and efficient matrix multiplication applications. The processor consists mainly of an array of 8×8 or 4×4 simple multipliers and at least one adder array.Type: GrantFiled: February 25, 2000Date of Patent: April 6, 2004Assignee: The Research Foundation of State University of New YorkInventor: Rong Lin

Patent number: 6705877Abstract: The present invention is a family of memory modules. In one embodiment a memory module with granularity and upgradeability of bandwidth, and a low profile uses 256 MB SDRAM or DDR SDRAM memory devices in chip scale packages (CSPs) to support a memory data bus width of up to at least 512 bits. Each module includes an impedance-controlled substrate having contact pads, memory devices, and other components on its surfaces. In one embodiment, the inclusion of spaced apart multiple area array interconnections allows a row of memory devices to be symmetrically mounted on each side of each of the area array interconnections, thereby reducing the interconnect lengths and facilitating matching of interconnect lengths. Short area array interconnections, including ball grid array (BGA) and land grid array (LGA) options, provide electrical communication between modules and the rest of the system. Thermal control structures may be included to maintain reliable operating temperatures.Type: GrantFiled: January 17, 2003Date of Patent: March 16, 2004Assignee: High Connection Density, Inc.Inventors: Che-yu Li, Sharon Laura Moriarty, Zhineng Fan

Patent number: 6697042Abstract: A large, efficient, high power collimated backlight assembly has a highly reflective, substantially closed, thin rectangular light cavity containing highly reflective surfaces and one or more light sources. One of the large faces of the cavity is a light exit plate which contains a transmissive, light collimating structure. The cavity side of the collimating structure includes a highly reflective white planar structure containing an array of circular apertures with minimal sidewall absorption. The apertures are centered on the optical axis and located near the focal distance of a closely packed array of hemispherical or spherical lenses located on the outer surface of the collimating structure. Light rays are trapped between the highly reflective surfaces of the cavity, light sources, and aperture walls, until they enter the lenses, which output the majority of rays that enter in a collimated beam.Type: GrantFiled: November 27, 2000Date of Patent: February 24, 2004Assignee: Rainbow Displays, Inc.Inventors: Jennifer M.

Patent number: 6693684Abstract: The present invention features are series of techniques for designing and assembling of large, robust monolithic and monolithic-like flat panel displays. Many techniques originally developed for creating tiled, flat-panel displays having visually imperceptible seams may be advantageously applied to monolithic structures. These techniques include single-sided wiring, two-sided wiring from opposite sides, segmented row and column lines, and reordering row and column lines in fan-out region. Single-sided wiring facilitates the construction of displays with small outlines. By using these techniques, display sharpness and contrast may be improved. In addition, color and luminance balance and uniformity across the display may also be improved.Type: GrantFiled: December 17, 2001Date of Patent: February 17, 2004Assignee: Rainbow Displays, Inc.Inventors: Raymond G.

Patent number: 6686830Abstract: An improved homodyne receiver I/Q receiver for use in RFID and similar applications. The receiver uses a lumped constant network approach to eliminate costly and bulky couplers, circulators and distributed delay lines. A unique single-pole, four-throw ( sp4t) antenna switching arrangement is also provided. The receiver combines small size with improved efficiency and sensitivity to provide a practical, low-cost, hand-held receiver capable of operation over distances of approximately three to five meters. This allows the construction of a hand-held receiver having high performance (i.e., a long reading distance) and good discrimination (i.e., the ability to accurately read closely-spaced tags moving rapidly past a check point). When used with compatible RFID tags, the inventive system may also be used to alter the identification or other information stored within the RFID tags.Type: GrantFiled: June 28, 2000Date of Patent: February 3, 2004Assignee: Applied Wireless Identifications GroupInventor: Murray Schirtzer

Patent number: 6680761Abstract: The present invention features designs of pixels and designs of control features for seals on AMLCD tiles optimized for tiling AMLCD flat panel displays (FPDs) which have visually imperceptible seams. The FPD structure has an image view plane which is continuous and remote from the pixel apertures or image source plane on the inside of the tiles. The image is formed on the view plane by a distributed ultra low magnification flies-eye optical system (a screen) that is integrated with the tiles, effectively excluding and obscuring an image of the seams. The innovations described herein minimize the defects on the perimeter pixels by effectively damming the waviness of the front of the seal near the perimeter pixels on the tiles. Dark space required for the seal between the interior tile edges and active regions of the pixels is decreased, as is the space allocated for wiring thereby increasing the feasible aperture ratios near the mosaic edges and all apertures.Type: GrantFiled: January 24, 2000Date of Patent: January 20, 2004Assignee: Rainbow Displays, Inc.Inventors: Raymond G.
