    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.

    摘要: 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.

    摘要: 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.
