摘要:
A system and method for performing extended space-time processing. An improved symbol decision is generated of a desired sub-channel of the signal vector by first generating a baseline decision for the sub-channel. A contribution of a strongest sub-channel is subtracted from the signal vector to generate a modified signal vector. The modified signal vector is multiplied by a unitary matrix generated from a QR decomposition of another channel matrix. Channel interference of the remaining sub-channels of the modified signal vector is cancelled from a remaining sub-channel.

A hydrogen-rich reformate gas generator (36), such as a mini-CPO, POX, ATR or other hydrogen generator provides warm, dry, hydrogen-rich reformate gas to a hydrogen desulfurizer (17) which provides desulfurized feedstock gas to a major reformer (14) (such as a CPO) which, after processing in a water-gas shift reactor (26) and preferential CO oxidizer (27) produces hydrogen-containing reformate in a line (31) for use, for instance, as fuel for a fuel cell power plant. The expensive prior art hydrogen blower (30) is thereby eliminated, thus reducing parasitic power losses in the power plant. The drier reformate provided by the small hydrogen generator to the hydrogen desulfurizer favors hydrogen sulfide adsorption on zinc oxide and helps to reduce sulfur to the parts per billion level.

A sequential punch press includes an upper die (10), a lower die (90), and an adjusting device (60) in the upper die. The upper die sequentially includes a punch set (20), a punch pad (30), a punch holder (40), and a stripper (50). A punch (70) is vertically and movably secured in the punch holder and received in the stripper. The adjusting device includes first and second sliding plates (64, 66) respectively having protrusions (65b, 67b), a piston cylinder (68) having a piston rod (682) fixedly connected with the first sliding plate, and a programmable controller for causing the piston rod to slidingly move the first sliding plate. When the first protrusions opposingly abut the second protrusions, the punch can extend beyond the stripper to punch a workpiece. When the first protrusions do not opposingly abut the second protrusions, the punch cannot extend beyond the stripper to punch the workpiece.

Either (a) the exhaust (20) of an engine (9) and/or (b) inlet air (11) is sent to a hydrogen generator (22) along with diesel fuel (18) to produce hydrogen and carbon monoxide (26) for either (c) mixing with the mainstream of exhaust fed to a catalytic converter (28) or (d) regenerating a pair of NOx adsorption traps (35, 36), thereby reducing oxides of nitrogen (NOx) to provide system exhaust (29) which may have less than 0.20 grams/bhp/hr of NOx and 0.14 grams/bhp/hr of non-methane hydrocarbons. A water recovery unit (52, 63) may extract water from either the exhaust or the effluent of the NOx traps to humidify inlet air (11) for mixture with fuel. Inlet air (11) may be humidified in an air bubbling humidifier (72) that receives water from a condenser (76) that uses inlet air to cool NOx trap effluent.
摘要:
A method and system for determining the commutation position in a DC machine using a single-bit rotor sensor and the back EMF signal from a stator winding by calculating a delay value, which is equal to the time elapsed between detection of the position signal and the back EMF signal, and establishing commutation after a period of time equal to the delay value has elapsed from when the position signal is detected.

A C4+ naphtha hydrocarbon feed is converted to light olefins and aromatics, by contacting the feed with a catalyst containing ZSM-5 and/or ZSM-11, a substantially inert matrix material such as silica and/or clay, having less than about 20 wt % active matrix material based on total catalyst composition, and phosphorus.
摘要:
Performance of transport protocols over a mobile data network is improved by a mobile accelerator, which performs protocol optimizations on-the-fly without requiring any modification to server or client protocol implementations in the operating systems of the server or client. The proposed mobile accelerator is compatible with existing TCP protocol implementations at the server and the client device, without server/client OS modification.
摘要:
An electro-optical switch or router includes a semiconductor oxide substrate and first, second, and third semiconductor waveguides disposed on the semiconductor oxide substrate. The third waveguide includes a transparent conducting oxide layer, an oxide layer, a metal layer, and first and second electrodes coupled to the third waveguide. The electrodes are configured to bias and unbiased the third waveguide to effect optical switching in the electro-optical switch. The oxide layer is disposed between the transparent conducting oxide layer and the metal layer. The switch may further include a semiconductor layer disposed under the transparent conducting oxide layer between the transparent conducting oxide layer and the semiconductor oxide substrate. The first electrode may be coupled to the transparent conducting oxide layer, and the second electrode may be coupled to the metal layer.
摘要:
Methods and apparatuses are provided that include selecting reference signal (RS) or other tones to utilize in estimating a channel for decoding one or more channels. Where the RS tones are interfered by other base stations, interference cancelation can be performed over the RS tones. Since interference can vary over the tones, interference cancelation can yield RS tones of varying quality. Thus, a quality of each of the RS tones can be determined, and at least a subset of the RS tones can be selected for estimating a channel. Additionally or alternatively, the RS tones can be weighted or otherwise classified for performing channel estimation using the RS tones.
摘要:
An injector for co-feeding liquid and solid fuels into a gasifier is provided. The injector includes a body, a first member, and a second member. The body comprises a first channel for conveying a liquid fuel. The first member surrounds the body to define a second channel for pneumatically conveying a solid fuel. The second member surrounds the first member to define a third channel for conveying a fluid stream for dispersing the solid fuel. The liquid fuel is atomized before being mixed with the solid fuel. A method for co-feeding liquid and solid fuels is also presented.
