Abstract: Service node for a telecommunication network (15) and method for determining a group of n user terminals (21) which are closest to a point of interest (22). First, a search range with an upper limit (24) is set. Then in an iterative manner, a current search cell of the set of cells (1-10) is determined and the search cell is queried for user data. The user terminals (21) are added to a set of found user terminals, and if the set of found user terminals comprises n or more user terminals (21), the upper limit (24) of the search range is adjusted to the nth lowest distance. This is repeated until no further possible cell (1-10) can be determined. The set of criteria can be set and matched with obtained user data to find a closest user terminal (21) having a specific role.

Abstract: A method and system is provided to access one or more historical incident databases, for example, CDC, CPSC, DTI, AAPCC and the like, for standardizing the potentially differing categories and coding among the databases. The standardizing includes recoding of the categories by providing a unified set of categories reflective of similar categories found among the one or more databases, if any. Submission of search queries allows users to obtain unified data across the databases so that incident history statistics for one or more products tracked by commonly available databases may be easily acquired. The resulting reports and statistics may be used by various entities to understand historical incidents from multiple perspectives including, for example, injury and fatality statistics as a function of age group, type of injury, time periods, diagnosis, injury outcome, severity, and the like. Data may be presented in standardized formats or in any of the native database formats.

Abstract: Hyperlinking or associating documents to other documents based on the names of people in the documents has become more desirable. Although there is an automated system for installing such hyperlinks into judicial opinions, the system is not generally applicable to other types of names and documents, nor well suited to determine hyperlinks for names that might refer to two or more similarly named persons. Accordingly, the inventor devised systems, methods, and software that facilitate hyperlinking names in documents, regardless of type. One exemplary system includes a descriptor module and a linking module. The descriptor module develops descriptive patterns for selecting co-occurent document information that is useful in recognizing associations between names and professional classes.
