Abstract: An excavation system for forming a wellbore through a subterranean formation, the system employing pressurized drilling fluid with impactors mixed therein. The pressurized fluid with impactors is directed to a drill string having a drill bit with nozzles on its lower end. The fluid impactor mixture is discharged from the nozzles and against the formation, wherein the impactors contact, compress, and fracture the formation to excavate through the formation. The system includes an impactor injection system that injects impactors into a stream of pressurized drilling fluid to form the mixture. The injection system operates at substantially the same pressure as the pressurized drilling fluid.

Abstract: Participants purchase into a given system for a given period of time. Those with investment gains, by definition, are without loss and need no compensation from the system. Those with investment losses are reimbursed by the system according to previously agreed upon terms. Total loss of a given system's participants is calculated, with that figure compared to the previously agreed upon amount of funds available for loss compensation (total revenue generated by participant premiums minus previously agreed upon detracted percentage for firm or a sum set forward by the company that is independent of a given system's generated revenue).
Abstract: A circuit includes a memory interface control circuit and a self-refresh adjustable impedance driver circuit having at least one adjustable impedance circuit. The memory interface control circuit selectively provides an impedance control signal based on memory self-refresh information. The self-refresh adjustable impedance driver circuit adjusts an impedance value of the adjustable impedance circuit in response to the impedance control signal. In addition, the self-refresh adjustable impedance driver circuit provides a memory interface signal based on the memory self-refresh information.

Abstract: A method of packaging a plurality of semiconductor chips comprises: providing a substrate panel having a first coefficient of thermal expansion (CTE); providing a carrier having a second CTE that is less than the first CTE; heating the substrate panel and the carrier to first and second elevated temperatures respectively; mounting the substrate panel at about the first elevated temperature to the carrier, the carrier being at said second elevated temperature, to provide a connection between the carrier and the substrate panel; and cooling the carrier and the substrate panel from the first and second elevated temperatures thereby putting the substrate panel into tension in at least one direction. A stiffener panel may be affixed to the substrate panel and heated to an elevated temperature and while the substrate panel is heated to an elevated temperature. A plurality of dies may be mounted and electrically connected to the substrate panel.

Abstract: The present invention provides artificial fusion proteins (AFPs) designed to elicit an anti-HIV immune response, as well as nucleic acid molecules and expression vectors encoding those proteins. The AFPs of the invention may comprise domains from various HIV proteins, such as Gag, Pol, Vif, and Env proteins, which are partial sequences. HIVCON is an AFP in which the HIV domains are from several HIV clade consensus sequences and which optionally contains additional domains which may be useful, for example, in monitoring expression levels or laboratory animal immune responses. Other aspects of the invention may include compositions and methods for inducing an anti-HIV immune response in a subject, preferably with a DNA prime-MVA boost strategy, and to induce a cell-mediated immune response.
Abstract: A method and system of subterranean excavating that estimates a buoyancy force applied to a downhole excavating system from drilling fluid. The estimated buoyancy force is used to derive a true weight on bit (WOB) at the borehole bottom. The derived realized WOB is compared to a target WOB to obtain a change in WOB. Based on the change in WOB, the excavating system is adjusted so the realized WOB approximates the target WOB. The excavating system adjustment includes applying a compensating force to the string. Compensating forces can be produced by manipulating a block assembly or deploying a thruster device in the string.

Abstract: A method and apparatus for hierarchical Z buffering stenciling includes comparing an input tile Z value range with a hierarchical Z value range and a stencil code. The method and apparatus also updates the hierarchical Z value range and stencil code in response the comparison and determines whether to render a plurality of pixels within the input tile based on the comparison of the input tile Z value range with the hierarchical Z value range and stencil code. In determining whether to render the tile, a stencil test and a hierarchical Z value test is performed. If one of the test fails, the tile is killed as it is determined that the pixels are not visible in the graphical output. If the stencil test passes and the hierarchical Z test passes, the pixels within the tile are rendered, as it is determined that the pixels may be visible.

Abstract: Voltage conversion and charging circuitry and method for converting an alternating current (AC) voltage to a direct current (DC) voltage for charging an energy storage element (e.g., battery or supercapacitor). An output capacitance, which is initially charged quickly for use in the slower charging of a battery, also maintains the charge on an input capacitance which provides power for the charging control circuitry during such charging process. In accordance with a preferred embodiment, the DC charging current is substantially constant during a first time interval following which the DC charging power is substantially constant during a second time interval.

Each set includes a diode across which is applied a nominal reverse bias voltage. These opposing reverse bias voltages are maintained at substantially constant predetermined nominal magnitudes in relation to the voltage at the signal electrode, thereby ensuring minimal leakage current via the signal electrode over the full dynamic range of the signal.
