20100152485 | SYSTEM AND METHOD FOR CONVERTING BIOMASS - In accordance with the teachings of the present invention, a system and method converting biomass into useful chemicals are provided. In a particular embodiment, the method includes fermenting biomass in one or more fermentors to produce a fermentation broth comprising ammonium carboxylate salts, the fermentors containing an ammonium carbonate or ammonium bicarbonate buffer. The method further includes reacting the ammonium carboxylate salts from the fermentors with a high-molecular-weight amine to produce amine carboxylate salt, and thermally cracking the amine carboxylate salt to produce carboxylic acid. In another embodiment, the ammonium carboxylate salts from the fermentors may be reacted with a low-molecular-weight amine to produce a low-molecular-weight-amine carboxylate salt. The low-molecular-weight amine in the low-molecular-weight-amine carboxylate salt may then be switched with a high-molecular-weight amine to form a high-molecular-weight-amine carboxylate salt, which is then thermally cracked to produce carboxylic acid. | 06-17-2010 |

20090216826 | GENERALIZED PROGRAMMABLE COUNTER ARRAYS - A Generalized Programmable Counter Array (GPCA) is a reconfigurable multi-operand adder, which can be reprogrammed to sum a plurality of operands of arbitrary size. The GPCA is configured to compress the input words down to two operands using parallel counters. Resulting operands are then summed using a standard Ripple Carry Adder to produce the final result. The GPCA consists of a linear arrangement of identical compressor slices (CSlice). | 08-27-2009 |

20140319706 | SELECTIVE WATER VAPOUR TRANSPORT MEMBRANES COMPRISING A NANOFIBROUS LAYER AND METHODS FOR MAKING THE SAME - A water vapour transport membrane comprises a nanofibrous layer disposed on a macroporous support layer, the nanofibrous layer coated with a water permeable polymer. A method for making a water vapour transport membrane comprises forming a nanofibrous layer on a macroporous support layer and applying a water permeable polymer to the nanofibrous layer. The water permeable polymer can be applied for so that the nanofibrous layer is substantially or partially filled with the water permeable polymer, or so that the coating forms a substantially continuous layer on one surface of the nanofibrous layer. In some embodiments of the method, the nanofibrous layer is formed by electro-spinning at least one polymer on at least one side of the porous support layer. In some embodiments, the support layer is formable and the method further comprises forming a three-dimensional structure from the water vapour transport membrane, for example, by compression molding, pleating or corrugating. | 10-30-2014 |
