摘要:
A method of writing data simultaneously on a plurality of tracks of an optical disk, comprises providing an array of light sources, each light source being independently modulated, providing means to determine the position of each light source with respect to the center of a given track, and varying the intensity of each light source so as to generate a plurality of writing light beams, each generated by a plurality of adjacent light sources, each of the said light beams having the desired width, intensity and position on the written track.

The present invention seeks to provide an improved system for inspection of and detection of defects in objects such as reticles, photomasks, semiconductor wafers, flat panel displays and other patterned objects. Preferably, the system has two or more stages, whereby the object is examined separately for fine defects, preferably by inspecting a binary level representation of the object, and for ultra fine defects, preferably by inspecting a gray level representation of the object. The system also preferably includes reinspection apparatus for reinspection of detected defects, thereby to reduce the false alarm rate, and for classifying the remaining defects by size, area and type.

A method of reading data from an optical disk comprises providing means for illuminating the required part of the disk and acquiring the optical image of a plurality of tracks, providing a detector matrix comprising a plurality of detectors, each of the detectors being capable of producing an output signal which is proportional to the intensity of the light detected by it causing an optical image corresponding to an illuminated area to fall on the said detector matrix, transferring the output signal of the detector matrix to image processing means, determining position coordinates of the track center for each data track, by analyzing the output signal of the said detector matrix, saving in memory means expected track center data, comprising position coordinates of the track center located by the analysis of the output signal, and if an actually detected track center is shifted with respect to the expected track center, electronically moving the track center position.

Devices and methods for substantially reducing the caloric efficiency of the digestive tract by capturing food being digested in the stomach 10 and/or anywhere else in the gastrointestinal (GI) tract, absorbing or encapsulating the captured food into multiple capturing members and moving such multiple capturing members containing the ingestible encapsulated food down the GI tract, practically out of reach of the GI absorption organs, thus excluding the entrapped ingredients from being involved in the digestion and\or absorption process. The device is designed for oral delivery. The system can be comprised of liquid, food bars or a capsule system. The capsule system is comprised of an external capsule that dissolves in accordance with a temporal or ph dependent preset, which allows the food intake to be at least partially fluidic. The capsule system is further comprised of a mechanism designed to capture and isolate a portion of the food being digested.

A tool for analog and mixed signal circuits includes a unit enabling a user to identify one or more critical interconnect lines in a chip architecture and one or more selectable, predefined topologies for said critical interconnect lines. Each topology includes one or more signal wires and a current return path. A majority of the electric field lines are contained within the boundary of the topology. The invention also includes a method for designing analog and mixed signal (AMS) integrated circuits (IC), including defining a chip architecture and a floor plan, identifying one or more critical interconnect lines and selecting pre-designed transmission line topologies for the critical interconnect lines.

A method of profiling code executed within a monitored tier of a multi-tier computing system includes the steps of periodically sampling the code executed by processing enclaves of the monitored tier, determining in real-time the periodical sampling overhead, dynamically adjusting the periodical sampling rate, identifying the business context of each code sample, and merging request traffic data and profiling data for presenting to an operator of the multi-tier system.
摘要:
The invention relates to monitoring a selected tier in a multi-tier computing environment with an apparatus that includes a context agent and a dynamic tier extension. The context agent is associated with the selected tier and is coupled with other context agents, each of which is associated with a respective tier. The dynamic tier extension is coupled with the context agent and with specific predetermined points of the selected tier. The dynamic tier extension monitors request traffic passing through the selected tier.

An optical pickup assembly for a multitrack optical disk reader includes a multi-element photodetector onto which a plurality of reflected track images are projected. Circuitry is provided for detecting a magnification error, and for generating a magnification error correction signal to correct or compensate for the magnification error. Circuitry is also provided for correcting for cross-talk components in the output signals of the multi-element photodetector responsive to the detected magnification error.
