摘要:
A pumping system comprising a pump (21) for conveying a pumped fluid using an actuating fluid. The pump comprising a rigid outer casing (25) defining an interior space (26), a tube structure (27) accommodated in the interior space (26), the tube structure (27) being flexible and substantially inelastic. The interior of the tube structure (27) defines a pumping chamber (28) for receiving pumped fluid. The tube structure (27) is movable between laterally expanded and collapsed conditions for varying the volume of the pumping chamber (28) thereby to provide discharge and intake strokes. The region of the interior space (26) surrounding the tube structure (27) defines an actuating region for receiving and accommodating actuating fluid. The pumping chamber (28) is adapted to receive pumped fluid to cause the tube structure (27) to move towards the expanded condition and the pumping chamber (28) thereby undergoing an intake stroke. The pumping chamber (28) undergoes a discharge stroke upon collapsing of the tube structure (27) in response to the action of actuating fluid in the actuating region. The pumping system also comprises a delivery means (50) for delivering pumped fluid to the pumping chamber (28) in timed sequence for causing the pumping chamber (28) to undergo an intake stroke, and means (70) for supplying actuating fluid to the actuating region in timed sequence to cause the tube structure (27) to laterally collapse whereby the pumping chamber (28) undergoes a discharge stroke.

Methods and apparatuses for remotely accessing data through a wireless device are disclosed. Preferably, the wireless device includes an ability to link data between software components operating on the wireless device. Additionally, the wireless device preferably includes an ability to reduce remote data access by identifying a first data type and a second data type used by a software component, retrieving data corresponding to the first data type from a service provider, retrieving data corresponding to the second data type from the portable device, and displaying on the portable device a return content result including both the first data type and the second data type.
摘要:
The invention provides a light-emitting device and a method of illumination. The light-emitting device includes one or more semiconductor layers, a reflective bottom surface, and a top surface coupled to semiconductor layer. The semiconductor layers include an active region where a primary light is generated. The relative position of the top surface, the reflective bottom surface and the active region is adjusted to substantially transmit the primary light through the sides of the light-emitting device.

摘要:
A backlight uses an array of red, green, and blue LEDs in a mixing chamber. The mixing chamber has reflecting surfaces and a top opening for illuminating LCD layers. A desired brightness profile and better color uniformity are obtained by using techniques including arranging the LEDs in certain sequences and patterns, providing a specular ring at the base of each LED, attenuating the brightness of the LEDs at the edges, and using widely separated diffusers in the mixing chamber. The arrangement, selection, and control of the multicolored LEDs may be tailored to achieve any desired white point specified by the display manufacturer.

Market data is recorded from a real live exchange. The recording data can be played back in real time or delayed, in any manner, to simulate the recorded market. Moreover, one or more users can participate in the simulated market just as if they were participating in a real-live market. The system provides a realistic trading environment without the associated risks of trading in a live-market such as losing money and the cost of making trades. The system may be used for training purposes and for purposes of testing and analyzing various trading strategies. Software developers and testers may also utilize the realistic environment to develop trading products or applications. Additionally, the system provides a means for demonstrating trading application products.

摘要:
Disclosed are supercapacitors having organosilicon electrolytes, high surface area/porous electrodes, and optionally organosilicon separators. Electrodes are formed from high surface area material (such as porous carbon nanotubes or carbon nanofibers), which has been impregnated with the electrolyte. These type devices appear particularly suitable for use in electric and hybrid electric vehicles.
