Title: Terabit per second atm packet switch having out-of-band control with multicasting
Inventor: CLOONAN THOMAS JAY
IPC: H04L12/56
Filed: 1996-07-09
Granted: 2001-02-13
Abstract: An out-of-band controller for a large packet switch which is distributed throughout partitions or pipes of the packet switch. Thus, the out-of-band controller is divided into multiple pipe controllers. These pipe controllers are connected andoperated in a ring such that each pipe controller is with a respective fraction of the input path requests for packets. The requests are processed concurrently and anyrequest that is not fulfilled in one pipe controller is offered to up to three subsequent pipe controllers to hunt a path for the awaiting packets. The controller, by using up to four levels of parallelism, can hunt paths and set up connections for 256 or more input ATM packet lines in normal monocast mode, thus providing a throughput of 1 terabit per second or more. A distributed controller design makes such tremendous aggregate switching speeds possible. The same general distributed controller design can also provide pipe hunting for a special packet operation called multicasting, in which one packet from one input line is transmitted to many or even all output lines. As can be appreciated, multicasting can monopolize system assets to the detriment of other ATM packets, so some multicasting may be made during special packet cycles when primarily multicasting packets will be carried. One such special packet cycle might occur at system initialization.

Abstract: A system and method provides for indexing and retrieval of stored documents using a decomposition of words in the documents in n-grams, or linear word subunits. The documents are indexed as pages in a number of banks. For each bank there is a bank index. The individual n-greens are identified for each page and are stored is the bank index. Each bank index further contains an entry map that indicates whether a given n-gram is present in any of the pages of the bank, and then provides an index to a page map that further indicates which page in the bank contains the n-gram. When a search query is input, the query words are decomposed into their n-grams. The query word n-grams are compared first with entry maps to determine if the query word n-grams appear on any page in the bank. If so, the associated page map is traversed to determine which page in the bank contains the query word n-grams.    The n-grams on the page are compared with the query word n-grams to determine the presence of a match therebetween. Matching pages are flagged. When all pages in all blanks have been processed, the pages are consolidated with respect to the documents to which they belong, resulting in a list of documents that match the search query. The results are displayed to a user.

Abstract: A fastening component of a separable fastener has some portion that is necessary for its fastening function, such as the hooks, the base to which the hooks are attached or a substrate that is used for another purpose, comprised of a magnetically attractive constituent. Another portion of the fastening component is comprised of a magnetically inert constituent. The fastening element may be the hook portion or the loop portion of a typical fastener. The fastening elements an d the base may be unitary, or of different precursors, such as in a woven fastener component. The magnetically inert constituent may compri se a polymeric plastic or a thermoplastic elastomer. The magnetic attractant may impregnate the magnetically inert constituent, or it may coat or be coated by the magnetically inert constituent. The magnetic attractant may comprise a metal powder. The metal may be select ed from the group consisting of iron powder. The magnetic attractant may be an organo-iron or a rare earth metal. In a woven fastener, either the base structure or the hooks may include the magnetic attractant, or both may do so. The material that forms the hooks may be entirely of a magnetically attractive material, with the material that forms the woven base being magnetically inert. Rather than the magnetically attractive material being incorporated into the fastening elements or the base, it may be incorporated into the substrate that is form ed from a precursor element that is separate from the base, and that is joined to the base.

Title: Improved location based paging for mobile telephone units
Inventor: HANSON ROBERT JOSEPH
IPC: H04W68/12
Filed: 1997-10-29
Granted: 2001-12-18
Abstract: An arrangement for paging mobile telephone units (MTU) in a cellular mobile system that conserves paging resources.  If the identity of the most recent cell in which the MTU was located matches the identity of the cell wherein the MTU was location on the previous registration, then an initial page covering only the cell of the most recent call location for the target MTU, and the neighboring cells for that cell, is used.  Advantageously, since the likelihood that the MTU is still within that cell or its neighbors is high, so that paging resources are conserved by paging in only a small number of cells.

Abstract: Methods and composition are disclosed for producing air-activated, i.e., oxygen activated, disinfectant-sterilent solutions. Solutions containing a haloperoxidase (i.e., a halide: hydrogen peroxide oxidoreductase, such as myeloperoxidase, eosinophil peroxidase or lactoperoxidase) plus a halide or combination of halides (i.e., chloride, bromide and/or iodide), an oxidase (i.e., a substrate: oxygen oxidoreductase) capable of generating hydrogen peroxide, and a substrate specific for that oxidase, are separately prepared under aerobic conditions, but all of the component solutions are made anaerobic prior to final combination and mixing. The anaerobic formulations are dispensed into containers capable of maintaining the anaerobic condition (e.g., pressurized canisters). Dispensing the solution at the time of use exposes the formulation to air (i.e., oxygen) which activates its disinfectant-sterilent properties.

Abstract: A rolling cone bit (10) includes a cone cutter (14, 15, 16) having a pair of adjacent rows of cutter elements (70, 80) that are positioned so as to divide the sidewall (5) and bottom hole (7) duty. The wear resistance, hardness and toughness of the cutter elements (70, 80) in the adjacent rows are optimized depending upon the type of cutting the respective rows perform. In most applications, the cutter elements (70) experiencing the sidewall cutting will have cutting surfaces that are more resistant or harder than the cutting surfaces of the cutter elements (80) in the rows experiencing more bottom hole duty. Likewise, the cutter elements (80) exposed to the bottom hole duty will generally be tougher than those (70) experiencing substantial sidewall cutting. The material enhancements include varying the grades of tungsten carbide used in the cutter elements (70, 80) and by selectively employing layers of superhard abrasives, such as PCD or PCBN. The cutter elements (70, 80) may be either inserts or steel teeth.

IPC: B07C5/36
Filed: 1996-07-31
Granted: 2001-03-27
Abstract: A method (95, 195, 300) of sequentially sorting pieces of material (Pi) in real-time into output bins (10, 12, 14) where each piece has a composition defined by a plurality of control elements. Each piece is analyzed (107, 208 , 315) to determine the concentrations of each control element in the piece. T he output bins are assigned target concentrations (100, 200, 306) of the contro l elements that are defined by customer requirements. The method establishes a  bin order (110, 210, 310) used during composition checking (112, 212, 316) t o place each piece in a selected bin. The selected bin is the highest order bi n that can accept a piece while retaining the actual concentration for each control element of the selected bin within the target concentration for each  control element of the selected bin. To optimize the value of the input material to be sorted the bin order is established for each piece based on real-time sort parameters that can determine via global optimization of data  from similar input material. Global optimization gives best blends of the known unique compositions and weights of the similar input material to maximize the aggregate value of the prescribed output compositions.
