Abstract: A N input and N output, scalable switching network (80) is implemented with an array of log base x of N rows and N/x columns of routers (40-68); where each router has 2x ports and where the rows of routers are connected to each other via a blocking compensated cyclic group mapping interconnect (49 and 59). A N input and N output, bi-directional scalable switching network (90) is implemented with an array of log base x of (N/2) rows and (N/2)/x columns of routers (40-68); where each router has 2x ports, and where the rows of routers are connected to each other via a blocking compensated cyclic group mapping interconnect (49 and 59). The routers provide destination routing. The levels of blocking compensated cyclic group mapping interconnect provide connectivity between the rows of routers.

Abstract: A [(Pt/Co/Pt)/Pd] multilayer thin film (40) provides improved perpendicular anisotropy and magnetic coercivity relative to Pt/Co multilayer thin films (10) without reducing the Kerr rotations provided by the component Pt/Co layers (44, 48, 46). [(Pt/Co/Pt)/Pd] multilayer thin films (40) comprise a substrate (26), an optional underlayer (110) including a crystallographically textured layer (114) of Pt and a crystallographically textured layer (116) of Pd, and several quadlayers (42) of Pt, Co, and Pd forming a periodic array (43) in the direction of the normal to the substrate (26). Each quadlayer (42) of the periodic array (43) typically comprises a first layer (44) of Pt atoms approximately one to two atomic monolayers thick, a layer (46) of Co between one and three atomic monolayers thick, a second layer (48) of Pt of substantially the same thickness as the first layer (44) of Pt, and a layer (50) of Pd that is at least as thick as the Pt layers.

Abstract: Apparatus for efficiently routing facsimiles to and from a plurality of facsimile devices (62, 64, 66). At least one BRI line (16) is coupled to several ISDN terminals (21-28). At least one multiplexer (31, 32) is coupled to the outputs of the terminals (21-28).

Coupled to the fax server (50) are a plurality of facsimile devices (62, 64, 66), each having a unique fax number. A given facsimile device (62, 64, 66) may send or receive more than one facsimile simultaneously by means of programming its fax number into more than one terminal (21-28) address. A terminal (21-28) may be coupled to more than one multiplexer (31, 32). Multiple BRI lines (16) may be used.

Abstract: A multi-component system for linking a user to a product or service provider includes a user processing device, a storage device, and a provider device. The storage device stores provider-specific application software, user-specific data, and a file management program. The storage device and the processing device are coupled to each other to form a user device which communicates with the provider device. Under direction of the file management program, the processing device carries out a recognition methodology which determines whether the processing device and the storage device are authorized to operate with each other. This aspect of the system makes it possible to render the storage device operable only with a specific user processing device, referred to as the principal processing device. This, in turn, reduces the possibility of fraud since the storage device cannot be used without the principal processing device.

Abstract: An imaging spectrometer that includes a mask (214) that has an array of n rows (302) and n columns (304) of transmissive elements (306) for transmitting the light from a plurality of locations of an image and of opaque elements (308) for blocking light from a plurality of locations of the image. The transmissive and opaque elements are arranged in a Hadamard pattern having rows (and columns) that are different cyclic iterations of an m-sequence. A grating (110) disperses the transmitted light from the transmissive elements (306) in a linear spatial relationship in a predetermined relationship to the wavelength of the transmitted light. A detector array (406) has a plurality of detector elements (408) arranged in a row to receive the dispersed transmitted light from the grating (110). Each detector element (408) provides an intensity signal indicative of the intensity of the light impinging thereon.

Abstract: Pattern recognition, for instance optical character recognition, is achieved by training a neural network, scanning an image, segmenting the image to detect a pattern, preprocessing the detected pattern, and applying the preprocessed detected pattern to the trained neural network. The preprocessing includes determining a centroid of the pattern and centrally positioning the centroid in a frame containing the pattern. The training of the neural network includes randomly displacing template patterns within frames before applying the template patterns to the neural network.

Abstract: A method for measuring the contours (30) of a three-dimensional object (4); and a method for calibrating an optical system (2, 8). The object (4) is placed into the field of view of the optical system (2, 8). The optical system (2, 8) is activated to obtain a set of data giving a phase (x.sub.t) at each of a plurality of pixels corresponding to the object (4). The phases (x.sub.t) are unwrapped, e.g., by a method of ordered phase unwrapping. The unwrapped phases are converted into a set of three-dimensional coordinates (x.sub.s, y.sub.s, z.sub.s) of the object (4) for each of the pixels. These coordinates (x.sub.s, y.sub.s, z.sub.s) can be portrayed on a display of a computer (10). The method for calibrating the optical system (2, 8) shares several common steps with the above method. In addition, coordinates of a test calibration fixture (38, 46) are first mechanically measured.

Light is dispersed in a prism arrangement which includes a selected liquid filled in the spaces between adjacent prism elements (41, 51). The indices of refraction and the apex angles of the prisms (41, 51) and the intervening liquid are set to limited deviation according to predetermined relationship. The prisms are mounted near the edges of mutually insertable tubes (62, 64) and a refractive liquid is secured in a containment space bounded by the prism elements (41, 51).

Abstract: Method and system for selectively retrieving information contained in a stored document set using a metric-based or "fuzzy" finite-state non-deterministic automaton. An automaton is constructed (501) corresponding to a text string query, text strings are read (502) from storage and corresponding dissimilarity values are generated (505). Those strings resulting in values less than a given threshold are recorded (508) and listed for the user. Dissimilarity values are determined based on penalties associated with missing characters, extra characters, incorrect characters, and other differences between the text string query and a text string read from storage.

Abstract: Method and system for selectively retrieving information contained in a stored document set using a non-literal, or "fuzzy", search strategy. A text string query is transmitted (200) to a computer processor, and a dissimilarity value D.sub.i is assigned (208) to selected ones of stored text strings representative of information contained in a stored document set, based upon a first set of rules (106). A set of retrieved text strings representative of stored information and related to the text string query is generated (212), based upon a second set of rules (107). Each of the retrieved text strings has an associated dissimilarity value D.sub.i, which is a function of at least one rule R.sub.n from the first set of rules (106) used to retrieve the text string and a weight value w.sub.n associated with that rule R.sub.n. The retrieved text strings are displayed (216) preferably in an order based on their associated dissimilarity value D.sub.i.

Abstract: An object movement estimator (400) predicts optical flow by estimating changes in sensed images using one-dimensional correlations. Sensed image portions are stored at a first instant of time and compared with sensed image portions at a second instant of time. An optimal flow is estimated by performing a one-dimensional correlation of the sensed image portions at the first and second instants of time, and a time-to-contact is estimated based on the predicted optical flow thus obtained.

Abstract: A multimedia authoring program includes a multimedia effect tool for applying and controlling direction of motion, visual, and sound effects for multimedia objects, including text, graphics, and the like, in a multimedia art work. The tool provides a set of palettes, each including a plurality of icons representing different motion and visual effects. The effects are applied to an object in each of a number of time segments that partition the overall duration of the object. The time segments can be enlarged or reduced as desired. For some time segments, including an entry and an exit time segment, there is an associated motion direction and visual effect palette. The motion direction palette allows selection of an icon representing a particular motion that is applied to the object during the runtime of the multimedia art work, whereby the object moves in the selected direction during the associated time segment.

Abstract: A thermally compensating lens mount (40) comprises an axially symmetric housing (42) that is formed from an inner layer of a first material (44) having a low coefficient of thermal expansion (CTE) to an outer layer of a second material (46) having a high CTE. The longitudinal cross-section of the housing (42) has a barrel shaped geometry along the symmetry axis (47) so that differential thermal expansion of the first and second materials (44, 46) decreases the length of the housing (42) along its axis of symmetry (47) by an amount determined by the CTEs of the inner and outer layers (44, 46), their thicknesses, and the geometry of the barrel shape.

Abstract: A general method of accelerating the classification of an unclassified input symbol S into a library of pre-classified templates employs a comparison inequality function. The correlation calculation is initiated between the input symbol S and templates retrieved from the library of templates. Templates with a low degree of correlation are excluded prior to completion of the correlation calculation to accelerate the correlation. Sorting by temple intensity permits the temple foreground pixels to be correlated first, which also accelerates the correlation calculation. A second sort by discrimination power permits critical conflict pixels to be correlated first for further accelerating the correlation calculation.
