The information search apparatus of the invention includes: a memory for storing character information therein, a display tablet having a function of displaying at least one character information and a function of inputting data, a detecting section for detecting a position at which an input pen has come into contact with the display tablet, and a control section for performing a control such that a function cursor, used for searching for arbitrary character information through the character inf...

A query comprising of sub queries, each of which could be of different media types are used to search a collection of multimedia documents in a database. These sub queries are parsed according to media type and operators/functions between these sub queries are recorded creating a set of query objects and query operator objects. The query interface than passes the query objects to the appropriate application programming interfaces (API's) of the various search engines. Furthermore, it applies the...

A route search apparatus according to the present invention comprises: a storage device that stores link positional information of individual links and link connection information between the links, a minimum unit of road on a map being referred to as a link; a departure point specification device that specifies a point of departure on the map; a destination specification device that specifies a destination on the map; and a control device that selects a start point link that is to constitute a ...

An interrogator for use with a plurality of identification systems using different frequencies and different methods of demodulation and decoding is provided. Each of the identification systems includes at least one transponder adapted to attached to an article to be identified and each transponder includes an antenna for receiving an interrogation signal from the interrogator and for responding to the received interrogation signal with a responsive signal. The responsive signal includes at leas...

A search type tuning device wherein the output signal representing the difference frequency between the output frequency from a voltage-controlled frequency sweep oscillator and a reference frequency is filtered by a low-pass filter; the difference between the output voltage from the low-pass filter and a predetermined driving voltage for sweeping the oscillation frequency of the oscillator is derived from an adder; the output from the adder is integrated by an integrator; and the output voltage...

An information search system, includes a storage device in which, for example, words are alphabetically arranged, each word being coded by a number for each letter or character and a number corresponding to the order of each letter in the word. The letter code numbers of a word to be searched are successively fed into an input station whose output actuates a counter for a unit and is also coded into a corresponding letter number. Two pickups and associated registers read out and temporarily stor...

A search and confirm frequency synthesizer for generating an output frequency which is a multiple of a predetermined reference frequency is disclosed. A first means is provided for generating a reference frequency signal. A second means is provided for generating a comparison frequency signal. A first spectrum generator means is coupled to the first means and produces a plurality of harmonics of the reference frequency signal. A second spectrum generator means is coupled to the second means and ...

A search method selecting unit included in a pattern search apparatus can automatically select a search method with the highest search speed from a plurality of search methods according to the number of search patterns, form, etc., in order to find a search pattern in a search target. An optimum search or replacement can be realized by finding or replacing the search pattern using the selected method.

A push type information providing service on the Internet. When information arranged on a time axis and retrieved is output time to time, the information is output/displayed in sequence on the time axis along a scenario described with position information of a plurality of data stored in databases distributed on the network. In displaying the position information of the data, secondary information such as advertisement, etc., is inserted onto the time axis of the position information of the retr...

A text search and retrieval system which builds an index representing every word in stored files created by a variety of applications, searches for requested words using the index and ranks the files based on the relative strength of match with the search request. From a display of the ranked filenames, the user can select a file, whereupon the file is tested to determine which one of a plurality of file viewers to deploy. The corresponding viewer is automatically loaded and used to display cons...
