Abstract: A method and apparatus for morphological analysis of neural cells may include receiving an immunohistochemistry (IHC) image of one or more neural cells; detecting the one or more neural cells in the IHC image using a first neural network, wherein the detecting includes identifying boundaries of the one or more neural cells; generating a segmentation cell mask using a second neural network based on the identified boundaries of the one or more neural cells; and classifying the one or more neural cells based on the generated segmentation cell mask using a trained classification model.

Abstract: A method of classifying radar emitters includes the steps of: (a) receiving pulses from multiple radar emitters over a plurality of consecutive first time intervals; (b) identifying pulses in each of the plurality of consecutive first time intervals corresponding to one or more first pulse trains using a first algorithm and de-interleaving the identified pulses from the plurality of first time intervals; (c) associating received pulses not identified and de-interleaved using the first algorithm with a plurality of consecutive second time intervals; and (d) identifying further pulses in each of the plurality of consecutive second time intervals corresponding to one or more second pulse trains using a second algorithm different from the first algorithm and de-interleaving the identified further pulses from the pulses associated with the plurality of consecutive second time intervals. Each consecutive second time interval is formed from two or more consecutive first time intervals.

Abstract: The invention is an apparatus (10) for treating inverted nipples and/or the collection of NAF.

Abstract: A method of classifying radar emitters includes the steps of: (a) receiving pulses from multiple radar emitters; (b) categorizing received pulses based on pulse data descriptors (PDWs); (c) forming clusters of received pulses based on the PDWs; and (d) de-interleaving pulses from the cluster using one of a differential time of arrival (DTOA) histogram technique, a spectrum estimation technique, or a Hough transform technique. Step (a) includes receiving the pulses during a predetermined time interval and storing the received pulses as a snapshot representing the pulses present during the predetermined time interval.

Abstract: A system and method for classifying radar emitters includes: (a) receiving a plurality of signals from the radar emitters; (b) generating data components for each signal received from the radar emitters; (c) forming multi-dimensional samples using the generated data components; and (d) sorting the multi-dimensional samples into a plurality of data clusters, based on their respective proximity to the data clusters, each data cluster representing a classification of a radar emitter.

Abstract: A processor (10) operable to calculate division and square root functions comprises a multiplier (48) having a multiplier array (116), a pipeline register (50), a correction generator (122), and a converter/rounder (52). The products generated by the multiplier array (116) are fed back to the multiplier (48) to avoid delays associated with the remainder of the multiplier circuitry. The correction generator (122) which performs a subtraction of the product output form the multiplier array (116) from a constant, is disposed between the multiplier array (116) and the converter/rounder (52). Hence, the subtraction necessry to compute the next estimate may be performed in parallel with other multiplications, further reducing the time necessary to perform the calculation. Compare circuitry (120) is operable to compare the final approximation with an operand to quickly determine the direction of rounding.

Abstract: A quality control phantom for a computed tomographic imaging instrument, such as a nuclear magnetic resonance scanner, is provided for the on-site calibration and standardization of image slice offset and angulation so as to maintain and insure proper operation. The phantom includes a cylindrical slab-like cast acrylic casing or body having a frustoconical groove formed therein. The groove is filled with a known material to effect a signal from the instrument. A scan taken by the NMR instrument across the frustoconical groove at an angle perpendicular to the central axis of the groove yields a circular image. The method for determining the image slice offset includes the step of relating the diameter of two such circular images so as to verify the distance one such image is from the other along the central axis of the groove. A scan taken by the NMR instrument across the frustoconical groove at an angle other than perpendicular to the central axis of the groove yields an elliptical image.

Abstract: In a microwave lens of the Rotman type for a scanning beam antenna a plurality of radiating feed probes are spaced along the focal arc. An illumination function is then commutated around the focal arc by energizing groups of the feed probes simultaneously in accordance with weighting functions to thereby cause the resulting radiated beam to scan in small equally spaced increments while the array factor remains essentially constant. Methods of calculating the weighting functions and feed probe spacing are shown.
