| 20090031787 | SYSTEM AND METHOD FOR GATHERING DIAGNOSTIC INFORMATION IN A PROCESSING PATH OF A COAL GASIFICATION SYSTEM - A system and method for gathering diagnostic information relating to an operating condition of a gas stream or processing path of a coal gasification system is disclosed. The information is gathered by deploying one or more specially constructed modules or seeds that proceed through the gas stream of the coal gasification system as part of the mass flow of the gas stream. The seed may be physically recoverable in which an outer material of the seed ablates when exposed to a predetermined temperature of the gas stream. The seed may be physically non-recoverable in which electronic circuitry transmits a signal to a receiver relating to the temperature of the gas stream. | 02-05-2009 |
| 20090064581 | PLASMA-ASSISTED WASTE GASIFICATION SYSTEM - A plasma-assisted waste gasification system and process for converting waste stream reaction residues into a clean synthesis gas (syngas) is disclosed. The feedstock is fed into a reactor roughly one-third from the bottom through the use of a feed mechanism. The reactor has three zones; a bottom zone where melting occurs, a middle zone where gasification takes place, and a top zone with integrated plasma torches to control the temperature and polish the syngas. The residence times in the three zones are selected to optimize the syngas composition and melted products. The syngas leaves the reactor and is partially quenched with relatively cooler synthesis gas. The partially quenched syngas is further cooled to recover heat for steam generation and/or preheating the waste stream to the reactor. The cold syngas is then processed to remove pollutants. The clean synthesis gas is combusted in power generation equipment to generate electricity, or converted to other fuels by chemical processes. | 03-12-2009 |
| 20100149934 | METHOD FOR FORMATTING AND READING DATA DISKS - The present techniques present methods and systems for increasing a data reading rate on optical data disks using a single reading head. The methods take advantage of the difference between a mean focal distance (MFD), or minimum spacing that the detector can distinguish between bits, and the minimum separation of bits in a single track to increase the reading speed. As the bits may be more closely spaced across adjacent tracks or layers, these techniques may be used to increase the reading speed of the disk. Specifically, the data symbols that make up a single bit-stream may be stored in a pattern horizontally across adjacent tracks, or vertically across adjacent layers. Accordingly, the focal point of the detector is scanned across the disk in the same pattern to read the individual data symbols. | 06-17-2010 |
| 20100157757 | SYSTEM AND METHOD FOR STORAGE OF DATA IN CIRCULAR DATA TRACKS ON OPTICAL DISCS - The present techniques provide methods and systems for reading and processing a data signal read from an optical data disc. In embodiments, an optical reader system may read data bits from a data ring in the disc. The data rings may be concentric, and a beginning of a sequence of data on the data ring may be in substantially the same position as an ending of the sequence. The reader may identify a data ring and begin the read process on the targeted data ring, and may end the read process when the reader reaches the starting point. The data sequence read from the data ring may be decoded to form a bit stream, which may be provided to various output devices. A circular trellis formed from the bit stream may enable the reading of a targeted data sequence without additional tail bits to improve data transmission efficiency. | 06-24-2010 |
| 20100157771 | METHOD AND SYSTEM FOR BIT PREDICTION USING A MULTI-PIXEL DETECTOR - The present techniques provide methods and systems for more reliable reading of optical data disks. In embodiments, a multi-pixel detector that is segmented into multiple areas, or detector segments, may be used to detect a pattern in the light reflected from an optical data disk. The pattern may include light scattered from a single bit that may be under a center detector, as well as light scattered from proximate bits. The detector system may then combine the quantized values from each of the detector segments mathematically to determine the presence or absence of a bit or bits of data. The mathematical combination may also use data that is known about the status of adjacent data bits (such as previously read bits, or bit patterns which are allowed or not allowed by specific data encoding schemes) to improve the accuracy of the bit prediction. | 06-24-2010 |
