  • Publication number: 20060078936
    Abstract: Solid support assays using non-standard bases are described. A capture oligonucleotide comprising a molecular recognition sequence is attached to a solid support and hybridized with a target oligonucleotide. In some instances, the molecular recognition sequence includes one or more non-standard bases and hybridizes to a complementary tagging sequence of the target oligonucleotide. In other instances, incorporation of a non-standard base (e.g., via PCR or ligation) is used in the assay.

  • Publication number: 20060035712
    Abstract: A system and method for placing a wager on events is disclosed. The system includes a web server connected to the Internet, a database in communication with the web server storing codes corresponding to at least one criterion associated with an event for an interactive voice response (IVR) system and generating a string of codes corresponding to a wager, and a graphical user interface. The graphical user interface is accessible from a client workstation separate from the web server and communicates with the web server to establish the wager. The graphical user interface initiates a call from the client workstation to transmit the string of code to the IVR system using voice-over internet protocols.

  • Patent number: 6972590
    Abstract: A data bus for a printed circuit board is disclosed having a plurality of lines separated by a substrate. A method is also disclosed for creating a bus with a reduced reflection of signal energy at the interface between the bus and a receiving agent connected to the bus. The lines in the bus include data lines and at least two strobe lines that are positioned adjacent each other to take advantage of the known impedance inherent to their dominant coupling. The bus includes separate data-line terminations and strobe-line terminations connected to the data lines and strobe lines, respectively. The separate terminations have values matched to impedances calculated from the separate sets of lines to more effectively reduce the reflected energy by more accurately matching the impedances on the lines.

  • Publication number: 20050131798
    Abstract: A method and system for administering the hedging of an employee deferred compensation plan, e.g., which employs hedging of NQDC plan liabilities using total return swaps and/or put and call options and/or forwards, for tax purposes. A plan coordinator coordinates a transfer of information between an employer/plan sponsor, a plan administrator that communicates with the employees/plan participants, and a balance sheet provider. The plan coordinator receives and reconciles data and then calculates and modifies relevant information for tax purposes and use in reports that are provided to the plan sponsor and balance sheet provider. Calculations and modifications for tax purposes allow the plan sponsor to reap tax benefits from the NQDC plan swap hedge. The reports include an upcoming transactions report, which indicates new compensation deferrals, reallocations of previously deferred compensation among specified indices, and withdrawals.

  • Patent number: 6836127
    Abstract: Two reference voltages and two differential receivers are used to detect low-to-high and high-to-low transitions on an input signal and set a received signal output. One reference voltage is set near but under the electrical high voltage level and the other is set near but above the electrical low voltage level. The reference voltage that is closest to the input signal is designated as the active reference voltage. When the input signal crosses the active reference voltage digital value of the received signal output is changed. When the input signal then crosses the inactive reference voltage, the inactive reference voltage is made the active reference voltage. A dead-time is then waited where input signal crossings of the active reference voltage are ignored. After the dead-time, input signal crossings of the active reference voltage will change the received signal output.

  • Patent number: 6820188
    Abstract: A circuit is provided to provide instruction streams to a processing device: embodiments of the circuit are appropriate for use with RISC CPUs, whereas other embodiments are useable with other processing devices, such as small processing devices used in a field programmable array. The circuit receives an external instruction stream which provides a first set of instruction values, and has a memory which contains a second set of instruction values. Two or more outputs provide instruction streams to the processing device. The circuit has a control input in the form of a mask which causes a selection means to allocate bits from the first and second sets of instruction values to different instruction streams to the processing device.

  • Patent number: 6695740
    Abstract: A differential assembly having first structure, which is configured to rotate along a differential axis in response to receipt of a rotational input, a second structure, which is supported for rotation on the differential axis, a third structure which is support for rotation on the differential axis and disposed between the first and second structures and operable in an engaged condition that transmits torque between the first and second structures and a disengaged condition that inhibits torque transmission between the first and second structures, a differential gear set, which is coupled to and rotatably supported within the second structure, and a biasing mechanism, which biases the third structure in the disengaged condition. The third structure is placed in the engaged condition if a torsional magnitude of the rotational input exceeds a rotational force exerted through the differential gear set. A vehicle drive train is also provided.

  • Patent number: 6697795
    Abstract: A virtual filesystem for allowing a large number of data files to be created, deleted, and rearranged by a peripheral device incorporating the filesystem without requiring the host computer system to delete and rebuild its cache and other file system tables. Since the directory hierarchy of the virtual filesystem is predefined, data blocks in the directory and file allocation table regions of the filesystem's filespace do not need to be prestored in memory, but rather are calculable at the time a data block read request is processed by the virtual filesystem. Since the specific location in the filesystem of a file is determined only at the time that one of a set of lowest-level directories which contains the file is accessed, host caching problems can be avoided by predefining a large number of files in the filesystem and avoiding reuse of any previously-used file.

  • Publication number: 20030142821
    Abstract: A variant on the ‘One Time Pad’ cipher is used to provide an encrypted link between two or more stations. The main feature of this variant is the use of a unique and easily created Pseudo-Random Number Sequence segment not having any internal repeats. At one station, a mixing function is used to combine a locally created stream of truly random bytes with a portion of this unique PRNS segment, yielding a fresh stream of truly random data. This freshly created stream of truly random data is operated on in such a way as to create a new and unique PRNS element set which is used to control the functioning of a PRNS generator. The PRNS generator is used to create a new and unique PRNS segment which has a repeat period much longer than the length of the PRNS element set used to create it. It is then useful to treat the PRNS element set as a message and transfer it across the encrypted link to other stations.
