A proximity sensor system includes a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by digital circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed.

The present invention relates to systems and methods providing content-access-based information retrieval. Information items from a plurality of disparate information sources that have been previously accessed or considered are automatically indexed in a data store, whereby a multifaceted user interface is provided to efficiently retrieve the items in a cognitively relevant manner. Various display output arrangements are possible for the retrieved information items including timeline visualizations and multidimensional grid visualizations. Input options include explicit, implicit, and standing queries for retrieving data along with explicit and implicit tagging of items for ease of recall and retrieval. In one aspect, an automated system is provided that facilitates concurrent searching across a plurality of information sources. A usage analyzer determines user accessed items and a content analyzer stores subsets of data corresponding to the items, wherein at least two of the items are associated with disparate information sources, respectively. An automated indexing component indexes the data subsets according to past data access patterns as determined by the usage analyzer. A search component responds to a search query, initiates a search across the indexed data, and outputs links to locations of a subset and/or provides sparse representations of the subset.

A method and system for assisting physically challenged users in positioning cursor objects at desired icons displayed within a graphic interface of a computer system. Icons are displayed within the graphic interface, such that an icon, when graphically selected by a user, facilitates a particular application function. Icon domains are established about each icon, wherein each icon domain is larger than the icon itself. The cursor object may thereafter be automatically positioned at the center of a particular icon, in response to moving the cursor object into an icon domain associated with that particular icon, thereby assisting physically challenged users in efficiently positioning the cursor object at the icon in order to graphically select a particular function associated with the icon. According to this method and system, the icons are thereby graphically magnetized, such that a cursor object is immediately snapped toward a desired icon when entering a graphically magnetized domain surrounding the desired icon, eliminating the need for positioning the cursor object precisely on the icon or other graphical object to be selected.

A negotiable instrument with fraud and identity theft protection and method of use is provided. The method includes step accepting a negotiable instrument having a pre-printed bar code, reading the bar code on a negotiable instrument using a bar code scanner, and receiving from the writer a code presented to the merchant for deriving personal information associated with the account holder and banking information associated with the account from the bar code. The method also having the step of comparing the personal identification information from the bar code with information provided by the writer. The merchant using the bank processing information derived from the bar code to process the negotiable instrument.

A method and system generates and compares fingerprints for videos in a video library. The video fingerprints provide a compact representation of the temporal locations of discontinuities in the video that can be used to quickly and efficiently identify video content. Discontinuities can be, for example, shot boundaries in the video frame sequence or silent points in the audio stream. Because the fingerprints are based on structural discontinuity characteristics rather than exact bit sequences, visual content of videos can be effectively compared even when there are small differences between the videos in compression factors, source resolutions, start and stop times, frame rates, and so on. Comparison of video fingerprints can be used, for example, to search for and remove copyright protected videos from a video library. Furthermore, duplicate videos can be detected and discarded in order to preserve storage space.

A system and method in which the position update rate is adaptively modified, based on previous position measurements. By adjusting the update rate based on velocity predictions from two or more position fixes, a lower update rate may be used without exceeding the maximum error. Lowering the update rate reduces power consumption in the UE, providing longer battery operation. The updating method may comprise periodically repeating the velocity prediction and periodically adjusting the update rate responsive thereto. The update rate may be adjusted using additional information such as an acceleration prediction, a minimum update rate, or a preferred error. In some embodiments a model for user movement may be used to provide more accurate predictions, for example, stationary, walking, jogging, city driving, and freeway driving. The updating method may comprise receiving user input regarding the maximum position error.

An electrosurgical pencil includes an adjustable-length suction tube which surrounds a stationary electrode to evacuate smoke and electrosurgical byproducts from a surgical site.
