| 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 |

| 20120004623 | ONE-WAY CHECK VALVE - A one-way check valve in an IV system set is provided with structural features to capture contaminant particles and inhibit the particles from adversely impacting the performance of the check valve. A screen can be provided upstream of the valve seat and the valve may be provided with flow channels for accumulating the particles. Modifications of the valve seat provide open volumes for accumulating contaminants. | 01-05-2012 |
