Abstract: A method and apparatus are described to perform cascading search methodologies records in a database. In one embodiment, the method comprises receiving a free-form search string, comprising one or more search terms, from a user, searching a database to identify records in the database containing the search string, if no data records are identified, searching the database by applying an ordered sequence of search algorithms to identify data records containing strings similar to the search string, and to display the identified records.

Abstract: An improved process for providing an individually customized fresh brewed coffee beverage on demand by a consumer, in a wide range of variety and strength. Said brewing process for making relatively large quantities of fresh brewed coffee beverages (in particular customized as to desired variety, body, character and/or strengths) as chosen by multiple individual consumers just prior to their consumption, with the system being easy to use by the consumer or other individual (i.e., restaurant wait staff) obtaining the customized beverage. Further, maintenance of the equipment requires only a small amount of personal attention by the owner/operator of the equipment. “Delayed dilution” of a concentrated extract to provide a beverage brewing system which immediately (upon customer selection) provides selective dilution (based on individual consumer's selections) of a fresh brewed coffee extract after the extract has been allowed to brew and held as an extract before dilution.

Abstract: A mandrel housing for permanently deploying a seismic sensor or sensor apparatus down a well is disclosed. The mandrel is formed integral with or attached to a pipe and is incorporatable into the production piping string. The outer diameter of the mandrel is designed to be slightly smaller than the inside diameter of the well casing which allows the mandrel to naturally come into contact with the well casing at points of deviation, non-linearity, or non-verticality in the casing. This mechanical coupling of the mandrel to the well casing, and hence the earth formation, improves the resolution and type of seismic signals to be detected by the sensor apparatus. The sensor apparatus fits into a groove on the mandrel and is preferably clamped or welded into place or placed within a tunnel formed in the mandrel. The mandrel further preferably contains channels on its side to allow materials within the annulus to flow around the mandrel even when the mandrel is in contact with the casing.

Abstract: The present invention allows an item to automatically be classified using its attributes based on a classification schema and a knowledge base. The invention can include selecting a first attribute of the item, designating a first search strategy comprising the value of the first attribute applied to operate upon data records in a first database, selecting a second attribute of the item; designating a second search strategy comprising the value of the second attribute applied to operate upon a second subset of data records in a second database, forming a search hierarchy comprised of the first search strategy followed by the second search strategy, executing the search hierarchy, and selecting at least one classification for the item based on the search.

The parking meters also have a motion sensor to detect any movement within it view range. The handheld device is able to extract all the parking states for each parking meter within a block or street depending on user configuration of system.

Abstract: An electronic catalog search engine is configurable to optimize the search process by identifying the desired item from the most advantageous supplier, while efficiently utilizing computing resources. The search engine comprises a configurable search and data subset creation mechanism. The system accepts search terms from a user, and then executes a sequence of search strategies on subsets of the database which may include a proximity search, a word count search, and a fuzzy logic search. Subsets can be searched in any order and different search strategies can be applied to different subsets. The sequences are terminated when search steps have uncovered at least one match. Each database entry has a corresponding product category. A list of categories from each of the matching products is dynamically compiled and displayed to the user. The user can page through the list of displayed matches, or alternatively can create a subset of the list by selecting only the items within one of the categories.

Abstract: An electronic catalog requisition system includes software for efficiently selecting items from a database. The software accepts search terms from a user, and then executes a sequence of search strategies on the database which may include a proximity search, a word count search, and a fuzzy logic search. The sequence is terminated when a search algorithm has uncovered at least one match. Each database entry has a corresponding product category. A list of categories from each of the matching products is dynamically compiled and displayed to the user. The user can page through the list of displayed matches, or alternatively can create a subset of the list by selecting only the items within one of the categories. In addition, the user can further refine the list of items by selecting those items having a particular attribute. The software can also maintain a list of synonyms for attributes as an aid for finding appropriate matches within the database.

Abstract: A TPON network in which the multiframe format includes a control portion, and a traffic portion. In the control portion the control word for each outstation is in the form of a respective group of contiguous bits. In the traffic portion, which is constituted by a series of traffic frames, the traffic information in each traffic frame for each outstation is in the form of a respective group of contiguous bits. Such a multiframe format enables the use of single-transducer transceiver in the outstations, and compared with known TPON multiframe formats increases the maximum operating range for the network beyond which transmit/receive conflict will occur.
