A handheld personal assistant including a voice-recognizer and a natural-language processor is disclosed. The recognizer is configured to transform a verbal expression from a person into a different mode of information (e.g., text). The natural-language processor is configured to process the mode of information to extract, from a database, a piece of information that is personal to the person. In processing, the processor analyzes the expression grammatically and semantically to transform at least a part of the mode of operation into at least one instruction. This piece of information can be a to-do list, information in the person's calendar or information from the person's address book, such as a phone number. The processor can still extract the piece of information when the person declares the expression differently.

The present invention provides an improved antenna system that, in one embodiment, includes an antenna array comprised of a plurality of elements, each of which is capable of providing a signal. Also included in the improved antenna system is a multi-beam beamformer for producing two spatially independent overlapping beams from the signals provided by two different subsets of the antenna array. The phase of the two beams is compared to realize an interferometer that can provide high or fine resolution data on the position of an object relative to the antenna system. The amplitude of the two beams can also be compared to obtain coarse data on the position of the object. The beamformer includes a switching network for selecting which elements of the antenna array form the two subsets. This permits, for example, the position of the beams to moved, the baseline of the two beams to be varied, and/or the beam width of the beams to be altered. To reduce adverse aerodynamic effects in certain applications, the antenna array is located conformal to the exterior surface of the body on which the array is mounted. Further, to reduce temperature related problems associated with high speed movement of the body on which the array is located, the array is located on the side of the body, as opposed to the front of the body. The side location also provides space for other types of sensors that are preferably located adjacent to the front surface of the body.

Traffic measurement should make it possible to obtain the spatial flow of traffic through the domain, i.e., the paths or trajectories followed by packets between any ingress and egress point of the domain. A method of sampling packet trajectories in a packet switching network allows the direct inference of traffic flows through a measurement domain by observing the trajectories of a subset of all packets traversing the network. A method which assumes that the measurement domain does not change comprises the steps of selecting packets for sampling in accordance with a sampling function of the packet content and generating a practically unique label for each sampled packet. The method does not rely on routing state, its implementation cost is small, and the measurement reporting traffic is modest and can be controlled precisely. Using the same hash function will yield the same sample set of packets in the entire domain, and enables us to reconstruct packet trajectories. An alternate embodiment which assumes no constraints and that the measurement domain may change comprises the steps of applying a sampling function and altering an invariant bit position as a signaling flag in each packet selected for sampling.

In one embodiment, a system authenticates a caller before providing the caller with access to one or more secured resources. Identification and verification data is stored during system enrollment of known persons. A processing system, in a current call initiated by a caller and prior to identification of the caller, receives voice-based information for the caller including a digital representation of a telephone number spoken by the caller in the current call, the received information including voice-based identification information and voice-based verification information for the caller. The processing system automatically compares the received identification information and the received verification information for the caller with the stored identification and verification data for known persons, respectively, to uniquely identify and verify the identity of the caller as a particular known person. The processing system authenticates the caller for access to the one or more secured resources in response.

A computer has instruction pipeline circuitry capable of executing two instruction set architectures (ISA's). A binary translator translates at least a selected portion of a computer program from a lower-performance one of the ISA's to a higher-performance one of the ISA's. Hardware initiates a query when about to execute a program region coded in the lower-performance ISA, to determine whether a higher-performance translation exists. If so, the about-to-be-executed instruction is aborted, and control transfers to the higher-performance translation. After execution of the higher-performance translation, execution of the lower-performance region is reestablished at a point downstream from the aborted instruction, in a context logically equivalent to that which would have prevailed had the code of the lower-performance region been allowed to proceed.

A touch panel includes first and second layers of electrodes. The first layer of electrodes is electrically connected in an arrangement that produces a regional ambiguity in a touch location determined using the first electrodes with respect to a first axis. The second layer of electrodes is configured to resolve the regional ambiguity of the touch location with respect to the first axis. Conversely, the second layer of electrodes may also be connected in an arrangement that creates regional ambiguity in touch location determination of the second layer, and the first layer of electrodes may be configured to resolve that regional ambiguity.

A user of a modeling application modifies an initial virtual object using a sketch drawn on one or more construction planes. Typically, construction planes are connected by an axis that intersects the virtual object. The user can draw a sketch on each construction plane, and the modeling application interpolates a shape along the axis between the sketches to determine what material in the virtual object is to be removed from it. In this manner, material may be removed to create a recess or hole in the virtual object or otherwise to slice away material from the object. A user can use two or more axes and construction planes to produce complex shapes from the initial virtual object. A user can also select a portion of a virtual object and mirror the selected portion. Modifications that the user makes in the selected portion are made correspondingly in the mirrored portion.

A machine based tool and associated logic and methodology are used in converting data from an input form to a target form using context dependent conversion rules, and in efficiency generating an index that may be utilized to access the converted data in a database. Once the data has been converted, an index data structure for each data object may be automatically generated that encodes one or more characteristics or attributes of the converted data so that an entity may access the data using the index structure. As an example, the one or more characteristics may include categories, subcategories, or other attributes of the data.

In a teleconferencing system, multiple parties participate in a teleconference from different locations. The system is configured such that a filmstrip containing simultaneous images or icons representing the participants are displayed on one or more display screens at a conference location in a spatial relationship that represents their real-world or virtual-world spatial relationships

Aspects of the invention provide ways to include emotive content in written communication. The emotive content serves many needs not currently addressed in written word computer applications and text generation aids such as word processors, web publishers, email, file archives, faxes, cell phones, PDAs other applications. Adding emotive content to messages adds information, which can help to interpret and amplify the text message, improve the message integrity and fidelity of communication. Emotional content can contain and convey the subliminal messages, which are vital to a user's interaction with one another via modern communication technologies. Aspects of the invention provide ways for the sender or author to add emotional content, which can capture, maintain, and focuses a receiver's interest.

Current expression of emotive content and emotive intensity in written word are rarely used because of lack of writing ability, lack of facilitation or lack of capability. An aspect of the invention provides mechanisms, which facilitate user emotive embedment in the written word without regard to personal language expression and language manipulation skills, vocabulary size or writing style.

Aspects of the invention provide sets of emotive primitives, mechanisms and techniques to manipulate these primitives to represent emotive states and emotive intensities while “co-existing” with the actual textual message in the communications. These are primarily done through the use of face glyphs, colors, animation, fonts and also sets of “feeling” words.

A disclosure of the present specification provides a method in a user equipment (UE). The method may comprise the steps of: activating a second cell when a request message for activation of the second cell by carrier aggregation is received from a first cell of one base station; receiving, from the one base station, a message including a configuration for switching to dual connectivity; and maintaining, without change, and using a configuration used for the second cell by the carrier aggregation after the switching to the dual connectivity.

We describe a method of blind source separation for use, for example, in a listening or hearing aid. The method processes input data from multiple microphones each receiving a mixed signal from multiple audio sources, performing independent component analysis (ICA) on the data in the time-frequency domain based on an estimation of a spectrogram of each acoustic source. The spectrograms of the sources are determined from non-negative matrix factorization (NMF) models of each source, the NMF model representing time-frequency variations in the output of an acoustic source in the time-frequency domain. The NMF and ICA models are jointly optimized, thus automatically resolving an inter-frequency permutation ambiguity.

When using finite-state devices to perform various functions, it is beneficial to use finite state devices representing regular grammars with terminals having markup-language-based semantics. By using markup-language-based symbols in the finite state devices, it is possible to generate valid markup-language expressions by concatenating the symbols representing the result of the performed function. The markup-language expression can be used by other applications and/or devices. Finite-state devices are used to convert strings of words and gestures into valid markup-language, for example, XML, expressions that can be used, for example, to provide an application program interface to underlying system applications.

A method and apparatus for selecting an item on a display screen with a touch interface by touching the display screen with a finger or stylus-type device. The touch point on the screen is detected, and a touch radius is established with respect to the touch point. When selectable items are detected to be displayed at least partially within the touch radius of the touch point, they are partially activated by altering the manner in which they are displayed. Upon detection of another touch point selecting a partially activated item, that item is fully activated and the other partially activated items are deactivated.

The invention provides an image semantic retrieving method based on a visual attention mechanism model, which is driven by data completely, thus understanding the semantics of images from an angle of a user as far as possible under the condition of no need to increase the interactive burden of the user, and being close to the perception of the user so as to improve the retrieving performance. The image semantic retrieving method has the advantages that: (1) a visual attention mechanism theory in a visual cognition theory is introduced into image retrieve; (2) the method is a completely bottom-up retrieve mode, thus having no need of user burden brought by user feedback; and (3) obvious edge information and obvious regional information in images are simultaneously considered, the mode of retrieval integration is realized, and the performance of image retrieval is improved.

Techniques are provided for resolving ambiguity in natural language speech. Speech is recognized using automatic speech recognition. A theory of discourse analysis is determined and at least one set of candidate discourse functions is determined based on the theory of discourse analysis. Prosodic features in the speech and a correlation between the prosodic features and the discourse functions is determined. The sets of candidate discourse functions are ranked based on the prosodic features in the speech information and a correlation to the prosodic features expected for the determined discourse functions. Ambiguity is resolved between sets of candidate discourse functions based on the rank information.

Verification of an inventory of stored products may be achieved by obtaining an image of the stored products and using text, optical character, and other feature recognition techniques to determine product identification and storage location. A comparison between earlier and current images of the same storage location is used to identify which locations have changed, i.e., from which locations have products been moved, removed, or added. The earlier and current images of the changed locations may be displayed to a user to visually inspect the differences between the images and verify the changes in inventory represented by those differences.

The invention provides a dynamic analysis method and system of a fracture-vug type carbonatite gas reservoir. Long-term production dynamic data and short-term well test data are combined to form complete production history data, so that the problem of multiple solutions of description of gas reservoir can be effectively solved, and the utilization rate of well test data is improved. Meanwhile, various critical problems about single-well gas deliverability, stable yield conditions, controlled active area and dynamic reserve volume of a single-well as well as parameters of strata permeability and the like in gas field development can be excellently solved by virtue of means such as analysis of well test, analysis of modern production decline and the like on the basis of the production history data.

Providing methods and systems to quickly and accurately respond to a natural-language question. The responses to the question can depend on additional information about the user asking the question, and the subject matter of the question the user asked. For example, the system knows that the user understands French, and can supply French answers to the user. Such additional information can improve on relevancy of the responses to the question. More than one responses can be provided to the user to allow the user to pick the more appropriate one. One embodiment uses a computer with a database having many phrases and question formats. The computer identifies phrases in the question based on at least one grammatical rules and phrases in the database. Then the computer links the phrases to categories based on at least one semantic rule, the subject matter of the question, and information about the user, such as previous questions asked by the user. The computer then selects at least two question formats based on at least the scores. After the question formats are selected, the system allows the user to pick at least one of the question formats so as to have an answer to the question generated.

A system and method are provided for binding a semantic to an event. The system includes a first network entity capable of transmitting a subscription message including an event package and a semantic description describing a semantic associated with the event package. The system also includes an event server capable of receiving the subscription message. The event server is thereafter capable of generating a semantic package identifier associated with the event package and the semantic description to thereby bind the event package to the semantic description. The event server is further capable of sending a first notify message to the first network entity, where the first notify message includes the semantic package identifier.

A method for indexing, extracting, analyzing, and utilizing co-occurrences of logical concepts in text documents is disclosed. References to logical concepts are detected by a text processing procedure by detection of descriptors, e.g., names, also including abbreviations, from a hierarchical dictionary with names and synonyms for said logical concepts, or database identifiers. Co-occurring concepts are indexed and stored in a database as a list or a table. Analysis of co-occurrences detects expressed and implied relationships between co-occurring concepts based on statistical and lexical text analysis. The method includes a procedure to create domain-specific hierarchical dictionaries for logical concepts in a given domain.

A VLF beacon operates in the near field of the antenna, providing a low impedance (magnetic) wave located by employing simple amplitude gradient and phase alignment direction finding (DF) methods. When rotated, the beacon antenna radiates its signal with little attenuation. Beacon antennas include a loop antenna which has a 1/r³ B-field amplitude relationship with distance. The antenna radiation range is limited, but the detectable near field signal is strong. The receiver comprises a simple 2-channel RF front end with filtering and an A/D converter. The antenna for each channel is a much smaller ferrite rod loaded loop.
