Abstract: Composite ghost cancellation reference (GCR) signals that make available both a chirp and a PN sequence during the same vertical-blanking-interval (VBI) scan line in each successive field facilitate more rapid and efficient calculations of ghost cancellation and of equalization, on a continuing basis. A television receiver for use with such composite GCR signals includes circuitry for separating the chirp and PN sequence portions of the GCR signals from the remainder of the composite video signal, a ghost cancellation filter and an equalization filter connected in cascade to respond to the composite video signal and provided each with adjustable filtering weights, and a computer. Random-access memory addressed during writing snatches the vertical-blanking-interval scan lines selected to include GCR signals. Sets of four successive ones of the selected scan lines are then additively and subtractively combined to separate the chirp portions of the GCR signals from a remainder of the composite video signal.

Abstract: A catch basin filtration system is disclosed. A filter body is dimensioned to fit within a drain inlet forming a trough or reservoir obstructing at least a portion of the inlet. The filter body is supported by a filter body support dimensioned to cooperatively engage with the interior walls of the inlet and with the filter body to substantially maintain said filter body in a pre-selected shape and position within the inlet. One or more connectors removably connect the filter body to the filter body support. One or more adjustable high fluid flow bypasses prevent the system from backing up and flooding surrounding areas during periods of high fluid flow.

Abstract: The present invention is directed to P1, P4-di(uridine 5?)-tetraphosphate, tetra-alkali metal salts such as tetrasodium, tetralithium, tetrapotassium, and mixed tetra-alkali metal cations thereof. The tetra alkali metal salts of P1, P4-di(uridine 5?)-tetraphosphate are water-soluble, nontoxic, and easy to handle during manufacture. These tetra-monovalent alkali metal salts are more resistant to hydrolysis than the mono-, di-, or tri-acid salts, therefore, they provide an improved stability and a longer shelf life for storage. The present invention also provides methods for the synthesis of P1, P4-di(uridine 5?)-tetraphosphate, and its pharmaceutically acceptably acceptable salts thereof, and demonstrates the applicability to the production of large quantities. The methods substantially reduce the time required to synthesize diuridine tetraphosphate, for example, to three days or less.
Abstract: A system for measuring available energy in a metal fuel cell is provided. The system comprises first componentry for measuring an electrical property of a mixture formed from one or more reaction products dissolved in a reaction medium. The electrical property may be such as to bear a known relationship with the concentration of the one or more reaction products. Using this known relationship, second componentry estimates the concentration of the one or more reaction products, and, responsive thereto, determines the available energy in the fuel cell.

Abstract: The present invention is directed to methods for improving the performance of an electrophoretic display by modifying the display cell surface. More specifically, the methods are directed to modification of the microcup surface after the microcups are released from the mold. The microcups which have undergone any of the treatment methods of the invention show significant improvement in their surface properties, such as chemical functionality, surface roughness, surface tension, morphology, surface charge, surface reflectivity, surface conductivity and optical properties, particularly optical density in the visible light region. An electrophoretic display formed from the treated microcups has many advantages. For example, the display shows a higher contrast ratio, lower electro-optic response time, lower driving voltage, longer shelf life, higher imageincreasing bistability and higher threshold voltage.

Abstract: The present invention relates to methods of searching and querying computers and websites connected to a distributed network such as the Internet. When the computers and websites are uniquely identified by an IP address or similar identifier, the processes of the present invention systematically proceed through a given range of addresses to be queried in a top-to-bottom manner. The process preferably comprises four stages: the Initial Process, the Second Pass, the Ping Process, and the Ping Follow-Up. Essentially, the Initial Process establishes a preliminary listing of computers that respond to requests transmitted over the network. The Second Pass attempts to establish a connection to computers with which a connection could not be established during the Initial Process. The Ping Process uses ping commands to verify the operability of non-responsive computers; and the Ping Follow-Up makes one final attempt to transmit requests to computers that have responded to ping commands.

Abstract: A wireless system comprises at least one subscriber unit in wireless communication with an infrastructure. Each subscriber unit implements a speech recognition client, and the infrastructure comprises a speech recognition server. A given subscriber unit takes as input an unencoded speech signal that is subsequently parameterized by the speech recognition client. The parameterized speech is then provided to the speech recognition server that, in turn, performs speech recognition analysis on the parameterized speech. Information signals, based in part upon any recognized utterances identified by the speech recognition analysis, are subsequently provided to the subscriber unit. The information signals may be used to control the subscriber unit itself; to control one or more devices coupled to the subscriber unit, or may be operated upon by the subscriber unit or devices coupled thereto.

Abstract: The present invention provides a method of preventing or treating retinal degeneration arising from pathophysiological or physical conditions. The method comprises administering to a patient a pharmaceutical composition comprising a purinergic P2Y receptor ligand, in an amount effective to elevate its extracellular concentration to activate retinal glial and neuronal cell surface P2Y receptors and mount a neuroprotective response. Methods of administering including intravitreal bolus and sustained administrations, transscleral delivery, topical, and systemic administrations. The pharmaceutical composition useful in this invention comprises a P2Y purinergic receptor agonist, which include uridine 5?-di-and triphosphate (UDP, UTP) and their analogs, adenosine 5?-diphosphate (ADP) and its analogs, cytidine 5?-di-and triphosphate (CDP, CTP) and their analogs, and dinucleoside polyphosphate compounds.
Abstract: Utilizing phenotypic markers in seeds or plants to allow qualitative detection of a proprietary trait in the harvest, to allow a quantitative calculation of the amount of the trait, and to facilitate the calculation and collection of fees for the trait. The phenotypic markers of the seeds can be the seed coat color, and said seeds can be homozygous or heterozygous for the phenotypic difference of seed coat color. Commercial cultivars of seeds with the phenotypic difference of seed color may be grown to include several different seed colors. Trait fees may be assessed on all grain with the proprietary trait, whether the grain was produced from purchased seed or from seed saved from a previous harvest.

Abstract: A method is disclosed for constructing, verifying, and maintaining underground vaults that isolate and contain radioactive burial sites. The method employs a buoyant lift technique to isolate a block of soil containing the contaminates from the surrounding soil. An impermeable synthetic liner is embedded in the vault to enhance the integrity of the system. The integrity of the vault is monitored by a system of sensors placed both inside and outside of the sealed vault. The method eliminates the need to excavate or drill in the contaminated areas.

Abstract: A wellbore fluid including a peroxide degradable polymer and an encapsulated peroxide source. The peroxide degradable polymer may be a polysaccharide. The peroxide source may include an inorganic peroxide, including zinc and alkaline earth metal peroxides, such as magnesium peroxide. The encapsulating material may be a polymer, including enteric polymers. The release of peroxide, from peroxide sources generally, can be controlled by means of pH such that peroxide source can be activated, and peroxide released, by a change in pH. In a wellbore, this pH change can be effected by using produced fluids to lower the pH of a more basic wellbore fluid.
