Abstract: A method for comparing a search print to a plurality of file prints includes performing a gray scale-based matching process, wherein cross-section profile pairs are determined between minutiae and landmark points in a search print and corresponding respondent prints, and individual similarity measures are computed based on the cross-section profile pairs using an elastic correlation process. A composite similarity measure is computed from the individual similarity measures. Optimizations such as segment outlier optimization (to eliminate outlier segments/minutiae points from the composite similarity measure computation) and adjusting the landmark point location in the search or respondent print can be implemented to maximize the composite similarity measure for a given respondent print. This maximized composite similarity measure can be combined with a similarity measure from another print matcher such as another gray scale-based matcher.

Abstract: An array of signals is adapted and dithered by use of a weight signal, a gradient signal with a carrier at a first frequency and an orthogonal sequence signal with a carrier at a second frequency, the dithered signals are then operated on to extract an output signal, a gradient signal, and a weight signal, which gradient and weight signals along with a generated orthogonal sequence signal, are then fed back for use in the dithering process. The carriers at different frequencies provide separability of predetermined components during the operation.

Abstract: A digitized topology data compression and decompression method provides the digitized topology data of a collection of segments connected to each other via nodes. The method forms at least one composite line representing a chain of connected segments, which reduces an overall number of lines needed to represent the collection of segments and where each composite line has two end points at known coordinates, resulting in compression of the topology data. The method further represents each composite line by its respective end point coordinates. Next, the method enrolls each composite line into one of at least two sets of composite lines for minimizing a number of intersections between each of the composite lines within each of the sets of composite lines. Finally, the method reconstructs the nodes at a decompression time by calculating coordinates of intersecting composite lines belonging to different sets of composite lines.

Abstract: An E-scan, space fed antenna is realized using non-active radiation and excitation arrays and a reduced number of phase and amplitude shifters. The linear radiation array is coupled to the concave excitation array by a parallel plate lens. An optimization technique allows the choice of a subset of the excitation array and the calculation of the optimum complex weight for each activated element of the excitation array. An antenna design allowing 80.degree. of scan and providing a maximum sidelobe level of better than -40 dB is disclosed which requires only 16 high resolution digital phase shifters and amplitude settings.
