Error correction coding for multiple-sector pages in flash memory devices
A flash memory system, including a flash memory device and a controller, and having improved efficiency error correction coding (ECC), is disclosed. Each page in the flash memory device has the capacity to store multiple sectors' worth of data. However, partial page programming (i.e., followed by a later write to fill the page) is prohibited for reliability reasons.

Method and system for approximate string matching
Approximate string matching of a target string to a trie data structure. The trie data structure has a root node and generations of child nodes each node representing at least one character in an alphabet to provide a lexicon of words and word fragments. The trie data structure is traversed starting from the root node by comparing each node of a branch of the trie data structure to characters in the target string and adding characters traversed in a branch of the trie data structure to a gathered string to provide suggestions of approximate matches. If a node is reached that is flagged as a node for a word or a word fragment and, if the target string is longer than the gathered string, the traversal loops back to the root node, and continues to traverse from the root node. This enables the trie data structure to use word fragments for compound words and to split non-delimited words where appropriate. A determination may be made, at each node, as to whether there is a correction rule for one or more characters in the remainder of the target string from the current node, and if so, the correction rule is applied to the target string to obtain a modified target string. |

Smart grey level magnifier for digital display
Systems and methods are provided that facilitate grey level magnification to improve details and contrast for a dark scene of video on a digital display system. Preferably implemented over a limited pixel level range, the video enhancement process counts the number of pixels corresponding to each level within the range in a frame and then, based on the percent level distribution of the pixels, calculates the stack of percentage distribution. From the stack of percentage distribution, a transformation process is performed to reassign the pixel values over a dark level range and to expand the distribution of the pixels. The result of transformation enhances the details and contrast of the dark area significantly without affecting the bright scene. By only applying the algorithm to dark scenes, computation loads are reduced compared with some of the full picture processing methods. Lower computational loads are important to reduce motion artifacts in high speed video applications. |

Frame timing synchronization for orthogonal frequency division multiplexing (OFDM)
A frame timing synchronization technique for orthogonal frequency division multiplexing (OFDM) systems is presented.

Method and system for hierarchical data reuse to improve efficiency in the encoding of unique multiple video streams
Data is shared across several simultaneous software video encode/compressions sessions with a common input video source. This reduces the amount of work done by each individual encoder by intelligently sharing/reusing data between encoders at various stages of encoding. Each encoder may use the data from another encoder “as-is” or may further minimally process the data. This data sharing reduces the overall encoding time of the streams significantly by reducing the duplicative work that would otherwise have to be performed by each encoder. Data sharing thus enables production of more simultaneous unique compressed video streams per encoding station. To allow sharing and reuse of data between encoders, various modules in the encoding pipeline operate in a hierarchical manner and use each other's output data, and cooperate to produce multiple unique video streams that may differ in format, bit rate, resolution, frame rate, or other video characteristic. |

Dynamic bandwidth allocation and service differentiation for broadband passive optical networks
A dynamic upstream bandwidth allocation scheme is disclosed, i.e., limited sharing with traffic prediction (LSTP), to improve the bandwidth efficiency of upstream transmission over PONs. LSTP adopts the PON MAC control messages, and dynamically allocates bandwidth according to the on-line traffic load. The ONU bandwidth requirement includes the already buffered data and a prediction of the incoming data, thus reducing the frame delay and alleviating the data loss. ONUs are served by the OLT in a fixed order in LSTP to facilitate the traffic prediction. Each optical network unit (ONU) classifies its local traffic into three classes with descending priorities: expedited forwarding (EF), assured forwarding (AF), and best effort (BE). Data with higher priority replace data with lower priority when the buffer is full. In order to alleviate uncontrolled delay and unfair drop of the lower priority data, the priority-based scheduling is employed to deliver the buffered data in a particular transmission timeslot. The bandwidth allocation incorporates the service level agreements (SLAs) and the on-line traffic dynamics. The basic limited sharing with traffic prediction (LSTP) scheme is extended to serve the classified network traffic. |

The method also allows examining strongly inclined surfaces having a steep inclination such that that traditional methods based on evaluating interference lines cannot be used because of a high density of the interference lines. |

Photoacoustic spectroscopy system
A system for providing photoacoustic spectroscopy. A light source having a quantum dot filter may provide a band of infrared light which is to be reflected by a lamellar grating to a photoacoustic chamber. The light may be modulated by the grating. The chamber may contain a sample of fluid for which spectral information is sought. A sensor may detect acoustic pressures in the chamber which indicate the spectral information. Signals from the sensor may be processed and displayed. Identification and concentration of certain substances in the fluid may be obtained. |
