Abstract: A measure of importance is calculated for segmented parts of a video. The segmented parts are determined by segmenting the video into component shots and then merging by iteration the component shots based on similarity or other factors. Segmentation may also be determined by clustering frames of the video, and creating segments from the same cluster ID. The measure of importance is calculated based on a normalized weight of each segment and on length and rarity of each shot/segmented part. The importance measure may be utilized to generate a video summary by selecting the most important segments and generating representative frames for the selected segments. A thresholding process is applied to the importance score to provide a predetermined number or an appropriate number generated on the fly of shots or segments to be represented by frames. The representative frames are then packed into the video summary.

Abstract: A system is disclosed for identifying matching arcs in sets of geometric objects, such as a pair of electronic maps, without relying on attributes being assigned to the arcs. An arc in a first set of geometric objects is identified as matching an arc in a second set of geometric objects, when the arc in the first set is co-bounded on both sides by polygons which match the corresponding co-bounding polygons of the arc in the second set. A determination is made of which polygons in the first set of geometric objects match polygons in the second set of geometric objects, by computing and comparing a set of similarity metrics. Examples of characteristics for which similarity metrics are determined include, proximity, area, shape and rotation. Each similarity metric is determined in an isolated fashion, so that no other metric is reflected in the metric being measured.

Abstract: A vector network analyzer (VNA) is provided with three test ports and an integration of hardware and software to make an integrated set of measurements for two and three port devices. The integrated capability allows for fast, versatile measurements that benefits, in accuracy and convenience, from sharing of data and resources with other measurements. The VNA includes a first signal source which is selectively connectable through reflectometers to two of the three VNA test ports. A second signal source provides connection through a third reflectometer to a third test port to enable full vector error corrected 3-port S-parameters measurements to be made. The two signal sources, along with software configuration of the VNA to operate in a non-ratioed mode provides for measuring second and third order intercept measurements. The two signal sources and software also enable the VNA to be used to make frequency translation measurements of a mixer including accurate frequency translation group delay measurements.

Abstract: A Variable Grain Architecture (VGA) device includes a shared output component (SOC) that may be used for programmably-routing process result signals onto either or plural ones of differently directed longlines within an FPGA. Plural VGB's make shared use of each SOC to output respective function signals to the longlines. The SOC may be also used for programmably-routing signals (e.g., feedthrough signals) that are selectively acquired from either one of equivalent but differently positioned interconnect channels. Such freedom in routing VGB result signals or feedthrough signals can allow FPGA configuring software to explore a wider range of partitioning, placement and/or routing options for finding optimized implementations in the VGA FPGA device of various, supplied design specifications.

Abstract: A microstrip termination is provided with a thin film resistor connecting a transmission line to a tapered edge ground, enabling high frequency performance, such as for optical modulators. The tapered edge ground is formed with metal deposited on a substrate edge between a top surface of a substrate containing the transmission line with thin film resistor, and a bottom surface with a metal coating forming a ground plane. The tapered edge is cut at an angle in the range of 30 degrees with respect to the top surface. The microstrip termination provides a wider bandwidth of impedance matching than a standard microstrip termination.

Abstract: A screw-threaded impeller 50 having a mixing device 55 thereon is provided in a container 10 of a food processor. A drive unit adjacent the bottom of the container is adapted to move the impeller in both a clockwise and a counterclockwise direction. During rotation, food placed within the container is lifted away from the mixing device when the impeller is rotated in one direction and is directed toward the mixing device when the impeller is rotated in the other direction. The mixing device includes a horizontal cutting blade 52 extending perpendicular to the impeller and a scooping blade 51 extending downwardly at an angle from the impeller. In order to lift over obstacles, the mixing device is spring mounted or can move along the helical protrusion toward the upper end of the impeller.

Abstract: A system for transferring information to and from a magnetic disk is disclosed wherein the information may be encoded on a data track in a large number of polarization orientations in comparison to conventional bidirectional recording schemes. In one embodiment of the present invention, it is contemplated that a single segment may be polarized in eight different orientations, each of which being distinguishable from each other by a read/write head. Polarization of a segment in one of eight different orientations significantly increases the amount of information which can be stored in any given segment relative to conventional systems which are polarized in only one of two orientations. Thus, the amount of information which may be stored on a disk may be increased without having to alter the linear or radial density of the disk.

Abstract: A microwave inductor including a coil with windings tapered from a first end of the coil to a second end of the coil to reduce resonant loss glitches found in conventional inductors which have uniform diameter windings. The coil further includes a core composed of a dielectric material containing a colloidal suspension of magnetic particles, the magnetic material preferably being iron powder and the dielectric preferably being epoxy, making the core a poly-iron material. The magnetic particles being colloidally suspended in dielectric increase the impedance of the coil at high frequencies to reduce resonant glitches without lowering the low frequency Q of the inductor. As such, a single coil can be utilized both in a filter which requires a low impedance at low frequencies to create a high Q, and as a bias line which operates at frequencies well beyond the resonant frequency of the inductor since a high impedance is provided by the core at higher resonant frequencies.

Abstract: A method for generating a tree structure representation of a generalized graph structure for display includes the more important links in the representation. Usage parameters are referenced in generating the tree structure from the generalized graph structure. Frequency, recency, spacing of accesses, and path information are exemplary types of usage parameters. A breadth-first or depth-first traversal of the graph references usage parameters associated with each node or link. The usage parameters which are associated with each node are referenced in order to determine the visitation order. The visitation order is determined by visiting the highest used nodes or links first. A method of displaying the tree structure references the usage parameters to determine the positioning of the nodes in the layout of the tree structure. In a preferred embodiment, the root node is positioned in the center of the layout. In one example, sibling nodes are spread out on links which emanate radially about their parent.

Abstract: A system is disclosed for warping models made from geometric objects, such as electronic maps, to correct local distortions in the models without compromising model topology. A set of transformation functions are derived from relationships between points in a first model that match points in a second model. The transformation functions are then applied to the points in the first model to generate a new model with reduced distortion. In order to provide for reducing local distortions, warping is applied to selected corresponding regions of the first model and the second model by triangulating these regions and generating transformation functions for each corresponding pair of triangles. Topology preservation is achieved by identifying matching points in the first model and the second model that have a potential for causing topology deviations. Such matching points are then excluded from the process of developing transformation equations to be used in the warping process.
