A video retrieval system is presented that allows a user to quickly and easily select and receive stories of interest from a video stream. The video retrieval system classifies stories and delivers samples of selected stories that match each user's current preference. The user's preferences may include particular broadcast networks, persons, story topics, keywords, and the like. Key frames of each selected story are sequentially displayed; when the user views a frame of interest, the user selects the story that is associated with the key frame for more detailed viewing. This invention is particularly well suited for targeted news retrieval. In a preferred embodiment, news stories are stored, and the selection of a news story for detailed viewing based on the associated key frames effects a playback of the selected news story. The principles of this invention also allows a user to effect a directed search of other types of broadcasts as well. For example, the user may initiate an automated scan that presents samples of broadcasts that conform to the user's current preferences, akin to directed channel-surfing.

An apparatus and method of control for converting DC (direct current) power from a solar photovoltaic source to AC (alternating current) power. A novel DC-to-AC power converter topology and a novel control method are disclosed. This combination of topology and control are very well suited for photovoltaic microinverter applications. Also, a novel variant of this control method is illustrated with a number of known photovoltaic DC-to-AC power converter topologies. The primary function of both control methods is to seek the maximum power point (MPP) of the photovoltaic source with novel, iterative, perturb and observe control algorithms. The control portion of this invention discloses two related control methods, both an improvement over prior art by having greatly improved stability, dynamic response and accuracy.

Preferably, the device further comprises an indicating means operably connected to the sensor for indicating an analyte quantity and/or concentration associated with the physiologic parameter.

Many media streams contain “objects” that repeat. Repeating objects in a media stream are defined as any section of non-negligible duration, i.e., a song, video, advertisement, jingle, etc., which would be considered to be a logical unit by a human listener or viewer. An “object controller” identifies such repeating objects as they occur, and provides an interactive user interface for allowing users to specify how individual repeating objects are to be handled either in real time, or upon subsequent occurrences of particular repeating objects. In general, the object controller includes a mechanism for identifying repeating objects, a mechanism for identifying temporal endpoints of those objects, a user interface for specifying actions to be taken when a particular object repeats within a media stream, and, in one embodiment, a buffer having sufficient length to allow for real-time deletion of objects from the media stream without obvious interruption in the str.

A method and system for providing high-speed, satellite-based information delivery is described. Improved communication channel efficiency is accomplished by employing an asymmetric data flow. The high bandwidth channel capacity of digital satellite systems is used for the download of large volumes of data. While relatively low speed communication channels are used for upstream data requests. The use of separate channels for upstream data and downloaded data provides an increased efficiency of use for typical internet and other electronic information service subscribers. A typical user in such systems generally makes relatively short information requests. These requests are then followed by large amounts of information being transferred to the user's computer in response to the request. The volume of data being downloaded often causes a capacity overload of typically used land lines. This invention solves this problem, without becoming prohibitively expensive, by employing digital satellite dish receivers to receive the high volume of downloaded data and using the relatively low speed communication channels low volume upstream requests. Moreover, this invention is designed to interface with all common communication devices as well as being designed to operate on and with all common computing platforms.

A fabrication method and a product for the deposition of a conductive barrier or other liner layer in a vertical electrical interconnect structure. One embodiment includes within a a hole through a dielectric layer a barrier layer of RuTaN, an adhesion layer of RuTa, and a copper seed layer forming a liner for electroplating of copper. The ruthenium content is preferably greater than 50 at % and more preferably at least 80 at % but less than 95 at %. The barrier and adhesion layers may both be sputter deposited. Other platinum-group elements substitute for the ruthenium and other refractory metals substitute for the tantalum. Aluminum alloying into RuTa when annealed presents a moisture barrier. Copper contacts include different alloying fractions of RuTa to shift the work function to the doping type.

The combination of contrast enhanced magnetic resonance imaging (MRI) and MR-guided subcutaneous core biopsy can be used as a robust approach for the diagnosis and treatment of breast cancer. MRI provides the means to accurately position and monitor interventional procedures such as biopsy, removal of tissue or other transcanular procedures. MRI may also be used in this invention to position and monitor the progress of breast conserving therapies (BCT), such as laser photo-ablation, cryoablation and localized hyperthermia. The general practice of this invention is to provide a remotely controlled apparatus for MR-guided interventional procedures in the breast. The apparatus allows the practice of a method that provides flexibility in conditioning the breast, i.e. orientation and degree of compression, and in setting the trajectory of the intervention. To that end, a robust conditioning/positioning device, fitted with the appropriate degrees of freedom, enhances the efficacy and efficiency of breast interventions by providing the flexibility in planning and executing an appropriate procedure strategy that better suits interventional procedures, either those in current use or yet to be developed. The novelty and potential commercial success of the device originates from its high maneuverability to set and perform the procedure strategy and its adaptability to accommodate an array of interventional probes. Remote control of this device can allow planning the operation and performing the relevant tasks in a short period, for example, within the contrast window provided by a single injection of a contrast agent, and this feature can be operator-independent.

A characteristic thumbprint is extracted from a data signal, the thumbprint based on statistics relating to the data signal. The data signal can be compared indirectly by matching this thumbprint against one or more reference thumbprints. The data signal may be any type of signal, including streaming digitized audio or obtained from static files. A database for containing a number of such thumbprints and methods for searching the database are also described.

An audio encoder for encoding an audio signal includes an impulse extractor for extracting an impulse-like portion from the audio signal. This impulse-like portion is encoded and forwarded to an output interface. Furthermore, the audio encoder includes a signal encoder which encodes a residual signal derived from the original audio signal so that the impulse-like portion is reduced or eliminated in the residual audio signal. The output interface forwards both, the encoded signals, i.e., the encoded impulse signal and the encoded residual signal for transmission or storage. On the decoder-side, both signal portions are separately decoded and then combined to obtain a decoded audio signal.

The method further including designing the interface based upon the categorized groups and on goals for the user interface.

First order predicate logics are provided, extended with a bilattice based uncertainty handling formalism, as a means of formally encoding pattern grmmars, to parse a set of image features, and detect the presence of different patterns of interest implemented on a processor. Information from different sources and uncertainties from detections, are integrated within the bilattice framework. Automated logical rule weight learning in the computer vision domain applies a rule weight optimization method which casts the instantiated inference tree as a knowledge-based neural network, to converge upon a set of rule weights that give optimal performance within the bilattice framework. Applications are in (a) detecting the presence of humans under partial occlusions and (b) detecting large complex man made structures in satellite imagery (c) detection of spatio-temporal human and vehicular activities in video and (c) parsing of Graphical User Interfaces.
