| 20100313992 | SYSTEM AND METHOD FOR THE AUTOMATION OF COLUMN AND MEDIA PACKING - This invention provides for the fully automated, hands free, packing of chromatography columns by means of delivering a pre-calculated volume of slurry and using two different packing modalities to stop the packing when either 1) this volume has been delivered in the column, or 2) when the adapter is moved to reach a bed height corresponding to the pre-calculated volume. Thus, a chromatography column can be packed in a fully automated fashion and such a column is 1) stable and 2) has the desired performance characteristic. | 12-16-2010 |

| 20090113403 | Replacing no operations with auxiliary code - A machine code computer program may comprise machine code directed to a main task and may contain no operations (NOPs). Some or all of the NOPs may be replaced with auxiliary code. Alternatively, the machine code computer program may be generated with auxiliary code where the NOPs would otherwise be. In some implementations, additional auxiliary code may also be provided in the machine code computer program. The auxiliary code and additional auxiliary code may comprise instructions that provide additional information about the machine code computer program in which they reside and its execution, but otherwise may act as NOPs with regard to the functionality of the machine code computer program. | 04-30-2009 |
| 20090254505 | RECONFIGURABLE HARDWARE ACCELERATOR FOR BOOLEAN SATISFIABILITY SOLVER - A hardware accelerator is provided for Boolean constraint propagation (BCP) using field-programmable gate arrays (FPGAs) for use in solving the Boolean satisfiability problem (SAT). An inference engine may perform implications. Block RAM (BRAM) may be used to store SAT instance information. Computation may be co-located with the BRAM memory, taking advantage of the high on-chip bandwidth and low latency of an FPGA. SAT instances may be partitioned into multiple groups that can be processed by multiple inference engines in parallel. New SAT instances can be inserted into FPGA without invoking the time-consuming FPGA re-synthesizing process. | 10-08-2009 |
| 20100057647 | ACCOMMODATING LEARNED CLAUSES IN RECONFIGURABLE HARDWARE ACCELERATOR FOR BOOLEAN SATISFIABILITY SOLVER - A hardware accelerator is provided for Boolean constraint propagation (BCP) using field-programmable gate arrays (FPGAs) for use in solving the Boolean satisfiability problem (SAT). An inference engine may perform implications. Learned clauses may be generated during conflict analysis. Operations pertaining to learned clauses may include clause insertion and clause deletion (e.g., by invalidation) from a learned clause inference engine, and “garbage collection” in which unused or invalidated clauses may be removed from an inference engine. | 03-04-2010 |
