Abstract: A system and associated methods determine the semantic similarity of different sentences to one another. A particularly appropriate application of the present invention is to automatic processing of Chinese-language text, for example, for document retrieval. A method for computing the similarity between a first and a second set of words comprises identifying a word of the second set of words as being most similar to a word of the first set of words, wherein the word of the second set of words need not be identical to the word of the first set of words; and computing a score of the similarity between the first and second set of words based at least in part on the word of the second set of words.

Abstract: The present invention provides a method and system for graphically displaying status information concerning the allocation of a process resource to a process entity. More particularly, the present invention provides a method and system for displaying the booking status between process entities and process resources in a control processing system. In order to display booking status between processing entities and process resources, the present invention identifies a process resource and multiple process entities (each of each can operate with the process resource), and displays a status indicator responsive to the status of booking requests of identified process entities for the identified process resource.

Abstract: Techniques used in coding software are described. An encoder encodes a machine executable program or portions of a machine executable program. The encoding process uses a cipher table, a unique key for encoding, and an agreement between the encoder and decoder as to what portions of a machine executable will be encoded. By using the decoder on a computer system which may execute the encoded machine executable, the decoder may serve as a recognizer to only execute those machine executable programs which have been encoded and are recognized by the recognizer. If a machine executable is not recognized or rejected, appropriate actions may be taken other than the machine executable.

Abstract: The invention provides systems and methods for continuous back up of data stored on a computer network. To this end the systems of the invention include a synchronization process that replicates selected source data files data stored on the network and to create a corresponding set of replicated data files, called the target data files, that are stored on a back up server, This synchronization process builds a baseline data structure of target data files. In parallel to this synchronization process, the system includes a dynamic replication process that includes a plurality of agents, each of which monitors a portion of the source data files to detect and capture, at the byte-level, changes to the source data files.

Abstract: A system and method is provided for non-invasively determining electrical activity of the heart of a human being. Electrical potentials are measured on the body surface via an electrode vest (12), and a body surface potential map is generated. A matrix of transformation based on the geometry of the torso, the heart, locations of electrodes, and position of the heart within the torso is also determined with the aid of a processor (24), and a geometry determining device (26). The electrical potential distribution over the epicardial surface of the heart is then determined based ona regularized matrix of transformation, and the body surface potential map. Using the epicardial potential distributions, epicardial electrogram, isochronal are also reconstructed, and displayed via an output device (28).

Abstract: In general, in one aspect, the description includes a method of responding to storage access requests. The method includes defining at least one write area and at least one read-only area, receiving a write request specifying a first address that resides within the at least one read-only area, determining a second address in the write address area, and storing data associating the first address with the second address.

Abstract: A system and method for a power supply system that charges a capacitor, wherein the capacitor charge drives a pulse discharge driven system. The power supply system utilizes a main power supply and a resonant inductor and capacitor configuration to charge the capacitor to a specified, large percentage of a driving voltage that is required by the pulse system. A control module monitors the capacitor charge and disconnects the main power supply when the capacitor charge is within the specified percentage. The main power supply disconnect causes the inductor to discharge and similarly charge the capacitor in a more controlled manner. Once the control module measures the capacitor voltage at the full driving voltage, the control module commands a switch to separate the inductor from the capacitor.

Abstract: Disclosed is a method and device for selecting documents, such as Web pages or sites, for presentation to a user, in response to a user expression of interest, during the course of presentation to the user of a document, such as a video or audio selection, whose content varies with time. The method takes advantage of information retrieval techniques to select documents related to the portion of the temporal document in which the user has expressed interest. The method generates the search query to use to select documents by reference to text associated with the portion of the temporal document in which the user has expressed interest, as by using the closed caption test associated with the video, or by using speech recognition techniques.

Abstract: An inductive flowmeter for measuring the flow velocity of a conductive fluid has an electrical circuit that advantageously utilizes minimal analog components, and hence has advantages over conventional systems. The circuit has an evaluation channel that measures a differential voltage induced across the fluid as it flows through a region having a magnetic field, and has a reference channel that provides a voltage indicative of the strength of the magnetic field. The differential voltage and the reference voltage are each digitized over the same time interval, and a programmable controller calculates a ratio of the digitized voltages to provide the flow velocity of the fluid.

Abstract: The invention is a system for digital watermarking that operates on a conventional digital video stream to etch, on hand, and read, on the other hand, digital watermarks in the stream that do not visibly interfere with the video content. A system according to the invention operates on digital data that has been transformed into the spatial-frequency domain, using inter-block differences between spatial-frequency coefficients to encode the bits of a digital watermark. Using the principles of the invention, it is possible to encode multiple watermark bits between two adjacent blocks, thus providing higher watermark data rates relative to underlying video content.
