A tuning system for a television receiver includes a phase locked loop (PLL) configuration and an automatic fine tuning (AFT) configuration which are selectively enabled to operate to tune the receiver to nonstandard as well as standard frequency RF carriers which may be provided by cable and master antenna systems. After the selection of a new channel, the operations of the PLL and AFT configurations are sequentially enabled by a mode control apparatus. During the operation of the AFT configura...

The present invention provides for a method of updatig an internet search engine database with the results of a user's selection of specific web page listings from the general web page listing provided to the user as a result of his initial keyword search entry. By updating the database with the selections of many different users, the database can be updated to prioritize those web listings that have been selected the most with respect to a given keyword, and thereby presenting first the most po...

A method of searching for files located in a computer system, wherein each file has at least one of a plurality of fields, by creating a search query, selecting a subset of the fields for searching wherein the subset is selected independent of the search query, and processing the files by examining the content of only those fields included in the subset for matching against the query. The fields can be selected by using a default setting. Certain fields are ignored during the processing step. An...

A search device, search system and search method extract related words of entered keyword from a related word dictionary file, to display one or more of the related words in a manner to accept selection, to perform search using selected related word keyword including desired number of the related word, and to display a search result. Furthermore, a search device is adapted to retrieve related words of entered keywords extracted from a related word dictionary file and to obtain search result usin...

A search engine and system for data, such as Internet web pages, including a query analyser for processing a query to assign respective weights to terms of the query and to generate a query vector including the weights, and an index network responsive to the query vector to output at least one index to data in response to the query. The index network is a self-generating neural network built using training examples derived from a feature extractor. The feature extractor is used during both the s...

A search apparatus and method for establishing efficiently whether a particular number, eg a MAC address, is stored in a database, eg in a communications bridge. The search is conducted stepwise on the basis of portions of the number, until one or zero match is found in the database. In the event that one match is found, a final confirmation is made that the whole of the number located and the number searched for are the same. This provides an efficient way to search among a subset of possible v...

A search engine system, server and method receives input from a user terminal regarding a mark and a description of its associated products or services. The search engine searches a database table which will have one entity associated with the input data. The entity's web site, a constructed web site, and/or a list of authorized vendors for the products or services or an error message is then displayed to the user via the user terminal. Each database record comprises a unique combination of a ma...

A system for searched digitized data permitting the simultaneous searching of several queries. To minimize excessive matches of queries, the search may be limited to selected portions of each of the documents being searched.

A file search apparatus which is provided with a base having a center pillar, a reel which comprises file accommodating rooms accommodating therein a plurality of files having codes and juxtaposed in a circle and is supported to the center pillar rotatably therearound, a selection device which is supported revolvably to the base to revolve along the outer periphery of the reel so as to read the codes on the files and search for a desired file, a driving device for driving the selection device, a...

A decoder for decoding received pseudo random sequence (PRS) codes modulated upon a carrier signal and having an original chip rate f.sub.c, and for correcting for unknown frequency shifts in the received PRS codes. The decoder includes a local oscillator for demodulating the carrier signal and detecting the received PRS codes and a signal source for generating X correction PRS codes each having a pattern of chips similar to the chip pattern of a predetermined one of the received PRS codes and e...
