摘要： An image detector monitoring system includes a detector framing node and a host computer having at least one host processor and a host memory. The detector framing node acquires image data, buffers the acquired image data, and outputs the image data to the host memory according to a predetermined communication protocol. The host computer executes operations according to a non-real time operating system, and a host memory stores the image data received from the detector framing node. The detector framing node is controlled by executing a plurality of event instructions, which are stored in an event queue. Some event instructions control a radiation generation system, while others control communication with an image detection system or control the detector framing node itself. Each event instruction executed by the detector framing node includes a bit flag indicating whether the event is to be traced by the detector framing node. Traced events are stored as entries in a response log in host memory. Each response log entry includes a time stamp indicating a time of execution of the traced event.

摘要： An imaging system shares control of host memory between a detector framing node and a host processor. The detector framing node is programmable to control generation and reception of image data. Image data is acquired and communicated to host memory independently from control by a host operating system. The detector framing node controls events according to an event instruction sequence and communicates received image data to the host memory through a computer communication bus. Image data is received by the detector framing node from a flat panel detector. Host memory has a first section managed by the host operating system and a second section not managed by the host operating system. Image data is communicated from the detector framing node into the second section of host memory. Event instruction sequences are communicated from the first section of host memory to the detector framing node to control the generation and reception of image data.

摘要： The present techniques provide systems and methods for modulation coding of data on optical disks, such as holographic data disks, and techniques for reading that data back from the disks. The techniques involve parsing a bit stream into a sequence of individual bit-patterns, and then using the individual bit patterns to select a symbol, or matrix, from a lookup table of previously selected matrices. The symbols are selected according to predetermined criteria that may help make the disk more resistant to interferences and errors, such as surface scratches, and the like. For example, criteria that may be used to select the symbols are the number of reflective and non-reflective regions within each matrix, and the number of sequential reflective regions, among others. The symbols may be written to the disk in a two-dimensional fashion, e.g., across adjacent tracks, or in a three-dimensional fashion, e.g., across adjacent data layers.

摘要： 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.

摘要： A turbo decoder control comprises an address generator for addressing systematic data, parity data, and systematic likelihood ratios according to a pre-determined memory mapping. The systematic data samples are accessed in the order required by the MAP decoding algorithm such that interleaving and de-interleaving functions in the MAP decoding algorithm are performed in real-time, i.e., without delay. Such memory-mapping in combination with data handling functions (e.g., multiplexing and combinatorial logic) minimizes memory requirements for the turbo decoder and allows for use of programmable interleavers, variable block lengths, and multiple code rates.
