  • Patent number: 8929159
    Abstract: A driver circuit includes pull-up and pull-down drivers driven by separate pre-drivers operating between different voltage rails. Data signals driving the pull-up driver and the pull-down driver are synchronized, and the pull-up driver and the pull-down driver are coupled together to produce an output signal having a voltage swing based on both the pull-up driver and the pull-down driver.

  • Publication number: 20140365987
    Abstract: An input/output circuit layout has a first section in which first transistors having a thicker gate oxide are located and a second section in which second transistors having a thinner gate oxide are located. Due to process technology constraints, the gates of all of the second transistors are oriented in a single common direction. The second section has a perimeter having a square shape including a first edge and a second edge adjacent to the first edge. First connection pins coupled to the second transistors are provided with an orientation that extends inwardly from and perpendicular to the first edge. Second connection pins coupled to the second transistors are provided with an orientation that extends inwardly from and perpendicular to said second edge. The square shape and presence of pins on adjacent first and second edges permits rotation of the second section to fit within different orientations of the layout.

  • Patent number: 8454952
    Abstract: Stretch-induced increased hemodynamic load adversely affects endothelial cell function and is an important contributor to thromboembolus formation in heart failure, valvular heart disease, atrial fibrillation, venous insufficiency, and pulmonary hypertension, and in thrombus occluded vein grafts. Local thrombus formation and thromboenbolic events can be reduced by inhibiting the TGF-beta signaling pathway or TGF-beta per se. Inhibitors can be administered to patients or veins (prior to interposition) at risk for thromboembolic events or local thrombus formation. Inhibitors can be applied to harvested veins to be used as arterial grafts.

  • Publication number: 20130111382
    Abstract: Embodiments are directed to providing support for customized element layouts in a user interface. In one scenario, a computer system provides a user interface (UI) for a software application. The user interface includes multiple different UI elements arranged according to a custom layout. The computer system receives a user input that indicates various user interaction characteristics that are to be customized for the UI by a custom layout panel. The custom layout panel selects a characteristic modification interface based on which user interaction characteristics are to be customized, and implements the selected interface to customize the indicated interaction characteristics.

  • Publication number: 20110238620
    Abstract: To facilitate data transfer between two databases, a transfer machine accesses both databases and finds matching records. The transfer machine determines and stores a match status of a record in one database. The match status indicates whether the record corresponds to at least one of the records in the other database, and if so, which record or records in the other database correspond to the record. If the match status indicates that the record matches a record in the other database, the transfer machine determines which record is current and updates the other record. If the match status indicates that a record has no match in the other database, the transfer machine adds a copy of the record to the other database.

  • Patent number: 8004345
    Abstract: A system and method for minimizing non-linearity errors induced in output drive voltage of a transmitter circuit due to on-chip process, voltage, and temperature (PVT) variations. The system including an oscillator for converting an input reference bias voltage into a clock output signal, where the input reference bias voltage varies in response to PVT variations. Also included is a counter for counting the clock output signal and generating a count value corresponding to the clock output of the oscillator. A comparison module operatively coupled to the counter compares the count value with a pre-simulated count value to generate an error signal. Based on the error signal generated by the comparison module, a correction logic adjusts an output drive signal of the transmitter circuit making it immune to PVT variations.

  • Publication number: 20080297229
    Abstract: A CMOS voltage reference circuit for a low voltage (1v), low power supply application is described. The circuit achieves a temperature coefficient of 31 ppm for a relatively large temperature range of ?40 C to 125 C. A combination of subthreshold current characteristics and moderate inversion operation of MOSFET's are utilized in conjunction to achieve a fairly stable temperature independent output voltage reference (VREF) from the circuit.

  • Publication number: 20080193626
    Abstract: A process for manufacturing amino acid-rich tea or tea extract is provided. The process uses tea starting material comprising at least 50 wt % of tea plant material harvested within 3 hours before and after sunrise and then processing the tea in a conventional tea process and packaging to provide a vendible tea product comprising at least 50 wt % of tea plant material harvested within 3 hours before and after sunrise. The observation that tea has more amino acids near to sunrise gives rise to a tea which is naturally high in amino acids.

  • Patent number: 7131119
    Abstract: A code optimizing procedure involves isolating code from a loop construct, executed a predetermined number of times, and optimizing the code for execution conditions which cause the loop to be executed that number of times. This code is compared against corresponding code which has not be optimized, and it is determined whether the inclusion of this code is favorable. If the benefits of including this code are judged to be significant, the code is modified by inclusion of this optimized code, which is conditionally executed when the loop is encountered.

  • Patent number: 7058561
    Abstract: A method, system and program product for optimizing software in which procedure clones are created based on the control flow information for the procedure body. In an example, a control flow graph for a called procedure is constructed and, for a branching node which can direct program flow to two or more code branches of the procedure, respective clones or new procedures are formed one for each code branch. A list containing pointers to the clones and the respective branch conditions for those clones is formed. Then, for each call site, the list is scanned to see if a particular call could be replaced by a call to a clone. Meanwhile, each clone is optimized and this may lead to removal of dead code or the replacement of a particular call statement by a constant.
