| 20090135937 | Trellis constellation shaping - A method for trellis constellation shaping is disclosed. In one embodiment, this method comprises receiving two or more input bits and filtering at least one of the two or more input bits to create two or more filtered output bits. The step of filtering at least one input bit introduces at least one extra bit. The method then encodes the input bits which are not filtered to create encoded bits and stores the encoded bits and the filtered bits in a buffer. A processing element may be configured to perform Viterbi type processing on the filtered bits to create processed bits. The method combines at least one of the processed bits with at least one of the buffered bits to create a combined bit set from the buffered bits and then performs mapping on the combined bet set to thereby map the combined bit set into a constellation. | 05-28-2009 |
| 20090238302 | Method and apparatus for signal coding - A method and apparatus is disclosed for use in a communication system for encoding data to achieve more efficient coding rates and high data transmit rate, or a lower bit error rate. An encoder may receive a portion of the data to be encoded and process the portion of the data to create encoded data. The encoded data and the portion of the data not sent to the encoder are presented to a transform module configured to perform matrix multiplication on the inputs with a transform matrix. The resulting transformed data is mapped, using a mapper, either via an algorithmic approach or a manual mapping approach to generating a constellation mapped output. 2-dimensional encoding may occur. | 09-24-2009 |

| 20090117600 | Detection of biological molecules by differential partitioning of enzyme substrates and products - This invention relates to a method and apparatus for detecting a biological molecule associated with enzyme activity in a sample. The invention is applicable to detecting a microorganism associated with an enzyme in a sample such as water, food, soil, or a biological sample. According to a preferred embodiment of the method of the invention, a sample containing an enzyme of interest or a microorganism associated with the enzyme is combined with a suitable substrate, and a fluorescent product of the enzyme-substrate reaction is selectively detected. The fluorescent product is detected with a partitioning element or optical probe/partitioning element of the invention. In one embodiment the partitioning element provides for partitioning of only the fluorescent product molecule into the probe. The invention also provides an automated system for monitoring for biological contamination of water or other samples. | 05-07-2009 |

| 20100285330 | Vapor Deposition of Dissimilar Materials - A method for depositing a first material on a substrate includes providing the substrate in a deposition chamber. A molten body is formed between the substrate and a source of the first material by melting one or more second materials. A flow of the first material is passed through the molten body and from the molten body to the substrate as a vapor flow. An essentially non-expending portion of the molten body comprises an alloy having a melting temperature below a melting temperature of the first material. | 11-11-2010 |
