Method and apparatus for indexing, searching and displaying data

A computer research tool for indexing, searching and displaying data is disclosed. Specifically, a computer research tool for performing computerized research of data including textual objects in a database or a network and for providing a user interface that significantly enhances data presentation is described. Textual objects and other data in a database or network is indexed by creating a numerical representation of the data. The indexing technique called proximity indexing generates a quick-reference of the relations, patterns and similarity found among the data in the database. Proximity indexing indexes the data by using statistical techniques and empirically developed algorithms. Using this proximity index, an efficient search for pools of data having a particular relation, pattern or characteristic can be effectuated. The Computer Search program, called the Computer Search Program for Data represented in Matrices (CSPDM), provides efficient computer search methods. The CSPDM rank orders data in accordance with the data's relationship to time, a paradigm datum, or any similar reference. An alternative embodiment of the invention employs a cluster link generation algorithm which uses links and nodes to index and search a database or network. The algorithm searches for direct and indirect links to a search node and retrieves the nodes which are most closely related to the search node. The user interface program, called the Graphical User Interface (GUI), provides a user friendly method of interacting with the CSPDM program and prepares and presents a visual graphical display. The graphical display provides the user with a two or three dimensional spatial orientation of the data.

Route Searching Device, Route Searching Method, and Route Searching Processing Program

The present invention provides a route searching device that can detect an optimum route with higher precision, a route searching method, and a route searching program.
The route searching device detects an optimum route among possible routes from a first point to a second point, on the basis of link costs that are set for a plurality of links constituting the possible routes. The route searching device makes at least one of a determination on whether there is a restricting element for restricting the movement of a movable body at the time of moving from the road corresponding to one link to the road corresponding to another link via the connecting portion corresponding to a node to which at least two links are connected, a determination on the number of links connected to the node, a determination on the shape formed with the roads corresponding to the links connected to the connecting portion corresponding to the node, a determination on attributes of at least one of the roads corresponding to the links connected to the node, and a determination on the conditions of the roads. The route searching device then acquires a node cost that represents the difficulty of the movement from the road corresponding to the one link to the road corresponding to the another link, the node cost being in accordance with one or a combination of two or more of factors including the existence of a restricting element, the number of connected links, the shape formed with the roads corresponding to the links, the attributes of the roads, and the conditions of the roads, the factors being on the basis of the determination results of the determining means. On the basis of the link cost and the acquired node cost, the route searching device searches for the optimum route.

Moving transmitter correlation interferometer geolocation

A Moving Transmitter Correlation Interferometer Geo-Location (MT-CIGL) system is disclosed that permits locating both moving and stationary transmitters from moving DF equipment. A conjugate gradient based search routine is utilized which solves for the location of moving and stationary transmitters at the start of each measurement sequence and then solves for the velocity and direction of motion of the moving transmitter. This information is used to track the moving transmitter. Received signals are sampled, digitized and stored in covariance matrices. They are then summed and normalized using an equation that has velocity terms that are set to zero to minimize extraneous correlation peaks, and a maximum correlation peak is developed. A conjugate gradient search routine is used to find the correlation peak of the summed data. The value of the peak is then analyzed to see if it is above or below a predetermined value. If the peak value is above the predetermined value the transmitter is stationary and the located correlation peak is the location of the transmitter. If the peak value is below the predetermined value the transmitter is moving and the peak does not indicate the correct location of the transmitter. Another conjugate gradient search routine is performed using the previous erroneous peak as the starting point for the search to identify the actual location of the moving transmitter at the beginning of a search sequence. That location is then processed through the same equation, but without the velocity terms set to zero, to calculate the velocity and direction of motion of the transmitter. This information can then be used to plot a track for the moving transmitter.
