Abstract: An optical storage medium having a three-dimensional data pattern, and fabrication method thereof. The optical storage medium includes a substrate and a plurality of recording layers, each constituting a fluorescent oligomer. Due to the high quantum yield and high stock shift of the fluorescent oligomer, the recording layers emit intensive fluorescent signals when the optical storage medium is illuminated with reading beams. Accordingly, the recording sensitivity and the readout characteristics of optical storage mediums are improved without additional signal-amplifying structures or materials.

Abstract: The invention discloses new benzoindole styryl compounds and its use for a high-density optical recording medium. The invention uses the dyes of the new benzoindole styryl compounds to form the recording layer of high-density recording media. The new benzoindole styryl compounds are easy to prepare and purify, so they are cheaper when comparing to the compounds generally used in high-density optical recording media. The benzoindole styryl compounds has a maximum absorption for the light wavelength in the range of 500 nanometers to 700 nanometers. The benzoindole styryl compounds also have high sensitivity and chemical stability for light and heat. Using the new benzoindole styryl compounds to form a high-density optical recording medium can match up with the short-wavelength laser beam for high-density optical recording media and have the advantage of a stable quality.

Abstract: A system, method and a computer usable medium tangibly embodying a program of instructions executable by the computer to perform a computer-based method for providing a conflict detection and resolution in a mid-tier server of a multi-tier client-server communication system which performs message synchronization in a client/mid-tier environment and replication in a mid-tier/server environment. The method defines a client/mid-tier conflict resolution look-up table listing all possible conflict states in the client/mid-tier environment and corresponding action rules, and a mid-tier/server conflict resolution look-up table listing all possible conflict states in the mid-tier/server environment and corresponding action rules. For any detected conflict state the method finds and executes the corresponding action rule.

Abstract: A programmable motion estimator includes one dual ported memory for storing an image block, the prediction error, and a temporary block used in interpolation, and a pixel-group random access dual ported memory for storing a search window. The two ports of the two memories are selectively applied to an arithmetic logic unit, or ALU, through a multiplexer. One output of the ALU provides an absolute difference, which is furnished to a tree adder. Another output of the ALU provides an average value or a difference value, as selected, which is routed to the inputs of the image memory and the search memory. In motion vector searching, the ALU performs pixel absolute difference arithmetic using the pixel groups from the image memory and from the search memory, and determines a sum of absolute differences in the tree adder. In half pixel interpolation, the ALU performs pixel averaging arithmetic using pixel groups from the search memory, and writes back to the search memory.

The relational database includes a super-column which is divided into a number of columns corresponding to the number of types of target tables. A respective column is allocated in the super-column for each of the types of the target tables. Valuable system memory space is consequently conserved. Multiple-typed tables and multi-targeted tables are supported, and multi-version data storage capabilities are provided.

The indolestyryl compounds exhibit strong absorbance in the visible light region (400˜700 nm) of the spectrum, resistance to heat and light, high light sensitivity, and excellent solubility, resulting from their special chemical configuration. Furthermore, the indolestyryl compounds can be used as recording layer materials in high density recording media for matching a reading laser wavelength and enhancing the reflective index and carrier-to-noise ratio (CNR) of the high density recording media. Accordingly, the recording sensitivity and the readout characteristics of high density recording media comprising the indolestyryl compound according to the present invention can be improved.
