  • Publication number: 20020001810
    Abstract: Certain small RNA molecules can serve as templates for exponential replication by Q-beta replicase. A single molecule can give rise to easily detectable replication products. This permits their detection at the single molecule level. In this patent application tripartite chimeric molecules composed of an RNA segment bounded on each side by a DNA segment are described. Although these chimeras are not templates for exponential amplification by Q-beta replicase they can give rise to such templates by enzymatic reactions which depend on the activity of reverse transcriptase. They can therefore be used as the basis for ultra-sensitive assays for reverse transcriptase. Modifications of the templates and the assays permit application of these chimeras and Q-beta replicase to ultra-sensitive nucleic acid hybridization assays and to assays for non-nucleic acid targets.

  • Publication number: 20010051342
    Abstract: This invention describes methods for the generation of nucleic acid probes that improve the sensitivity of hybridization assays. The sensitivity increase results from structural modifications of nucleic acids that promote network formation during hybridization with the result that a single target molecule becomes attached to a complex of many probe molecules. The structural modification involves fragmentation of the probe nucleic acid followed by joining the fragments together such that their order and orientation and number is altered from the original probe molecule. The result is the generation of permuted probe libraries. Various fragmentation and joining methods are described. Labeling can be done by standard methods before during or after formation of permuted probe libraries. Individual members of permuted probe libraries can be isolated and amplified and perpetuated.

  • Patent number: 6092053
    Abstract: A system and method for merchant invoked electronic commerce allowing consumers to purchase items over a network and merchants to receive payment information relating to the purchases. The system includes a server having software which gathers the purchasing information from a consumer to complete a purchasing transaction over a network. The system has a consumer data structure that stores purchasing information for registered consumers. The software is able to access the consumer data structure and enter the consumer's purchasing information during subsequent purchases. Having the software obtain and enter the consumer's purchasing information, the consumer does not have to enter the same information every time they purchase an item over the network. In alternate embodiments, the same technology can be applied to other arenas where a user may have to enter the same repetitive information.

  • Patent number: 6002279
    Abstract: A clock recovery circuit that can be used for recovering a clock signal from a data stream having a high data rate. The clock recovery circuit has a phase interpolator and non-linear digital to analog converters. These circuits are used to interpolate between the phases produced by a voltage controlled oscillator. A determination to advance or hinder a currently selected phase can be made using an up/down detector, a divider, and control logic. The divider can divide not only the up and down pulses produced by the up/down detector, but also the clock frequency. By dividing the clock frequency, the control logic can be designed using CMOS logic circuits.

  • Patent number: 5922898
    Abstract: The present invention provides a process for preparing biaryl compounds comprising reacting an arylmetal reagent selected from arylmagnesium reagents and aryllithium reagents with an arylhalide in the presence of a catalyst system comprising a catalyst selected from nickel catalysts and palladium catalysts and a cocatalyst selected from zinc cocatalysts and cadmium cocatalysts. The present invention specifically provides a process for the preparation of 2-(4'-methylphenyl)benzonitrile comprising reacting a 4-methylphenylmagnesium reagent with a 2-halobenzonitrile in the presence of a catalyst system comprising a catalyst selected from nickel catalysts and palladium catalysts and a zinc cocatalyst.

  • Patent number: 5539413
    Abstract: An integrated circuit for use in a phased array antenna system having a central processing unit. The integrated circuit is associated with one of a plurality of antenna elements of the phased array antenna system. The integrated circuit includes an ID memory for storing a unique ID addressable by the central processing unit, and receives global commands from the central processing unit globally transmitted over a distributed serial bus. Upon detecting a global command, the integrated circuit compares an ID address associated with the global commands with the ID stored in the ID memory. The integrated circuit recognizes global commands as local commands to be executed locally when the ID address associated with the global commands is the same as the ID stored in the ID memory. In response to the local commands, the integrated circuit generates and provides control signals to the associated one of the antenna elements of the phased array antenna system.
