A system and method are provided to alert two mobile communications users in the event they come in close proximity to one another. The present system uses a distributed algorithm denoted as the Strips algorithm, in which a pair of moving friends with mobile telecommunications devices makes an agreement about a static buffering region between them. After the agreement is made, the users do not need to follow each other's location until one of them enters the buffering region for the first time. By doing so, they invalidate the agreement. Consequently, they replace a location update message between them, determine if they got within the vicinity of each other, and otherwise make a new agreement on a new buffering region. When one of them enters the buffering region for the first time, a message is sent to both friends alerting them of the proximity of the other.

A system for automatic proximity-based preloading of relevant information in portable devices pre-loads a portable device such as a mobile telephone, a personal digital assistant (PDA) or portable computer before the occurrence of a trip or event, with information relevant to the user's current or upcoming tasks. The system locates and loads into the portable device only the information required by the user for near term projects, meetings, or trips. The system is generally comprised of an information catalog, a proximity estimator, a relevance estimator, an information retriever, and a device loader. The information catalog contains a list of the information sources and items to which the user has access and from which the system of the invention will retrieve data to be loaded into the mobile device. The proximity estimator determines the proximity of various relevant information items to the user's tasks based on distance, time, and / or association. The relevance estimator combines these proximity measures into a single relevance score. The most relevant information is retrieved by the information retriever and loaded onto the portable device by the device loader.

Character recognition includes detecting a union of characters, preprocessing the union of characters, comparing the preprocessed union of characters with one or more template symbols, and applying a decision rule to either reject a template symbol or decide that the template symbol is included in the union of characters. Such preprocessing involves representing the union of characters as one or more curves, and parameterizing the curve(s); and, regarding various classes of transformation, forming one or more shapes for the curve(s). The comparing operation involves forming one or more geometric proximity measures, and determining for every shape the values of those measures between the shape and correspondingly determined shapes for the template symbols.

The second signal is operated upon during presence scanning to determine to determine proximity of the element relative to the screen and during location scanning to produce a magnitude map of the mutual capacitance changes.

Computer-implemented systems and methods for synthesis of concept definitions and concept relationships from a domain of data, utilizing different semantic processing protocols such as formal concept analysis and faceted classification synthesis from existing domain concepts that have a confidence gradient built into them. A cognitive or an input agent provides an input of an active concept which is matched against existing domain concepts. The resultant pool of relevant domain concepts is then used to derive virtual concept definitions using a semantic processing protocol. The derivation is then overlaid with a concept of relative proximity of an attribute from another within an attribute set. An additional layer of coherence is given by the relative proximity measure. The end result is a pool of related virtual concept definitions in a tree structure.

The approach by a user to a location of interest along the walkway, such as an intersection, bathroom, or Braille telephone, may be indicated through the provision of a pattern of irregularity of the conductivity within the continuous electrical conductor. Different patterns of irregularity may indicate different advisories to the user.

A speech receiving unit receives a user ID, a speech obtained at a terminal, and an utterance duration, from the terminal. A proximity determining unit calculates a correlation value expressing a correlation between speeches received from plural terminals, compares the correlation value with a first threshold value, and determines that the plural terminals that receive the speeches whose correlation value is calculated are close to each other, when the correlation value is larger than the first threshold value. A dialog detecting unit determines whether a relationship between the utterance durations received from the plural terminals that are determined to be close to each other within an arbitrarily target period during which a dialog is to be detected fits a rule. When the relationship is determined to fit the rule, the dialog detecting unit detects dialog information containing the target period and the user ID.

Methods and apparatus are disclosed for identifying a particular region in an image based on a user specification and information in the image, such as color and texture information.

To compensate for color-calibration sensor drift, a measurement of bare-print-medium tonal value is taken in immediate time juxtaposition to each color test pattern; measured bare-medium tone is then used to correct color-patch readings. A line sensor or the like, on the scanning printhead carriage, is used for the reading. Preferably two such readings are taken, one at each end of each test pattern; ideally separate scans of the bare medium are taken without any test-pattern patch to develop longterm and short-term drift profiles, for refining the corrections. To compensate for calibration error due to runout in the carriage track—particularly for wide-bed printers—sensor response to bare medium is used to represent variations in carriage-to-medium spacing along the track; these variations are corrected in later sensor use.
