摘要:
A method for minimizing idle time of a controller in a graphics system, which includes a graphics memory and a graphics accelerating device that interconnects the controller and the graphics memory, is disclosed. The graphics accelerating device includes a command register for storing command signals from the controller therein, and a graphics engine for receiving and executing the command signals stored in the command register one at a time. The method includes the steps of: detecting whether number of the command signals in the command register which are yet to be executed by the graphics engine has reached a predetermined threshold number; transferring the command signals, which are yet to be executed by the graphics engine, from the command register to a reserved space of the graphics memory when the predetermined threshold number is reached so as to permit the controller to store continuously the command signals in the command register in order to minimize idle time of the controller; and determining whether the reserved space of the graphics memory contains the command signals transferred from the command register, and providing the command signals in the reserved space of the graphics memory, instead of the command signals stored in the command register, one at a time to the graphics engine for execution by the graphics engine.

A power converter for converting an input signal having an input DC voltage level to an output signal having a desired output DC voltage level. The power converter includes a switching converter having an input which receives the input signal and a floating differential output which includes a first output and a second output. The switching converter is operative to convert the input signal to an offset voltage equal to a difference between the desired output DC voltage level and the input DC voltage level. The offset voltage is generated across the first output and the second output of the floating differential output. The input signal is applied to the second output of the floating differential output to sum the input DC voltage level with the offset voltage and thereby produce the desired output voltage level at the first output.

cDNAs encoding a class of receptors, including the IL-8 type B receptor, have been identified in human tissue. Recombinantly produced IL-8 type B receptor is used in the preparation and purification of antibodies capable of binding to the receptor, and in diagnostic assays. The antibodies are advantageously used in the prevention and treatment of inflammatory conditions.

An implanted blood pump system is described wherein power for driving the pump is provided by a transcutaneous transformer having an external primary winding and an implanted secondary winding. Control of the driving voltage to the pump is provided by an implanted shunt regulator. Voltage applied to the primary winding is controlled in accordance with the power factor sensed in the primary winding.

An inverted LED filament includes a circuit board, a plurality of inverted LED light-emitting parts, and pad groups. The inverted LED light-emitting parts are arranged on strip-shaped portions of the circuit board and the pad group is located on the same side end of the strip-shaped portions, when the pad group is connected to a connecting base of an external LED bulb through connection with external pins. The pins can be prevented from blocking light generated by the inverted LED light-emitting parts.

A golf swing training device and method of use is provided. The golf swing training device has an elongated member with a first end disposed opposite a second end. The first end includes a slot which is sized to receive shaft of a golf club. The slot is disposed at a diagonal angle relative to the elongated member such that the shaft of the golf club passes through the elongated member. A curled member is disposed at the second end which can wrap around a shoulder of a user. In use, the golf training aid provides tactile feedback to a user as they execute a golf swing and aids in training the user to keep their arms in a proper position throughout a backswing and a golf swing motion.

A magnetic device assembly is provided for maximizing the size of the magnetic components for a predetermined power converter module by co-locating and sharing input, output, and auxiliary terminals between the substrates for the power converter and the magnetic components. Wherein complete power module is the result of constructing the separate constituent parts which include an integrated magnetic substrate, magnetic elements mounted therein, a power converter substrate, associated incorporated components located top and bottom on the power converter substrate, a composite mechanical footprint as defined by the mechanical extents of the integrated magnetic substrate and power converter substrate, and a composite electrical pinout as defined by the input-output pins which are coincident to and co-located as those of the integrated magnetic and power converter substrates.
摘要:
A passive annular grout seal assembly is disclosed for sealing an annular opening between a driven pile and a skirt pile sleeve for an offshore platform. The annular seals are located at the bottom of the pile sleeves near sea floor and automatically activated when piles are inserted and driven through the pile sleeves without any active operational procedure during offshore piling. The seal configuration fully utilizes the seal height, the grout column height and the density difference between grout and sea water to produce enhanced sealing capacity against the column of grout above.
