Devices and methods for substantially reducing the caloric efficiency of the digestive tract by capturing food being digested in the stomachand/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.

Device and method for reducing calorie intake

A method and system are provided for using a computer to facilitate a sales transaction between a group of buyers and at least one seller. Potential buyers may create a group organized for purchasing a product/service from one or more sellers. The computer system may output the buyers' collective request for the product/service to one or more sellers of the requested item. The sellers may respond by providing a price quotation for the requested item, often on the basis of the number of such items to be purchased by the group. The computer system notifies group members of the submitted seller quotations, in response to which some buyers may commit themselves to purchasing the item at the specified price or otherwise indicating a price at which they would be willing to commit to purchasing the item. Sellers may review the price quotations submitted by other sellers and submit competing price quotations. In a typical arrangement, an iterative process ensues in which sellers offer lower and lower prices for the requested products/services until reaching a point at which one or more buyers in the group are sufficiently comfortable with the price to commit themselves to purchasing the product/service.

A multi-track optical disk reader is provided having an optical pickup including multiple reading beams arranged in a pattern, such that each beam is directed towards a track to be read. The optical pickup is at least partly mounted on a swing-arm mechanism that orients the reading beam pattern with respect to the tracks being read. Methods and apparatus are provided for maintaining a desired position of the reading beams with respect to the tracks on an optical disk.

Method and apparatus for reading multiple tracks of an optical disk

Methods and apparatus are provided for detecting and correcting magnification errors while simultaneously reading or writing multiple data tracks with a multi-beam optical disk drive. An optical head for the optical disk drive includes a plurality of laser diodes that generate multiple light beams for reading from or writing to the optical disk, means for detecting a magnification error, and means for compensating for the magnification error to align the multiple light beams with multiple data tracks. A number of opto-mechanical systems are provided for correcting the magnification errors in the beams.

An optical pickup for simultaneously reading a plurality of data tracks of an optical storage medium is provided. The optical pickup uses a diffractive element to split an illumination beam into a plurality of reading beams which are projected onto a plurality of tracks of the optical storage medium. Apparatus and methods are shown for improving the optical characteristics of the optical pickup by reducing vignetting, optical aberrations, and field curvature. These improvements are achieved by relocating the diffractive element at a greater distance from the laser source, so that a diffractive element having a larger period, and a smaller angle between diffractive orders may be used. The apparatus and methods shown also reduce the number of components and the manufacturing cost of the optical pickup.

Methods and apparatus are provided for synchronously reading data from multiple tracks of an optical disk using multiple illumination beams. Circuitry is provided for use with a photodetector array to read and buffer data in parallel from the multiple adjacent tracks, while asynchronously providing processed data to a host processor. Circuitry is further provided for concurrently processing the signals read from the multiple data tracks to recover the data stored in the tracks.

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

The present invention provides an optical system having a read mode, during which multiple tracks of an optical disk are simultaneously read, and a write mode, during which data is written to at least one track of the optical disk. The multiple light beams employed during read mode may be generated by a single laser diode operated at low power used in combination with a diffractive element, multiple laser diodes, or combinations thereof.

A focus detection system for use in a multi-beam optical pickup assembly is provided that uses an optical element, either a holographic element or diffractive element, to split beams reflected off of a data-bearing surface of an optical disk into a plurality of data beams and a plurality of focus beams. The optical element also introduces astigmatism into the focus beams. The focus beams are projected onto focus detectors configured to account for overlap between adjacent focus beams to produce an accurate focus error signal.

Methods and apparatus are provided for illuminating an optical disk in a multi-track optical disk reader. A laser beam is collimated and focused onto an area including multiple, adjacent data tracks on the optical disk. To minimize noise caused by interference resulting from the reflection of multiple beams from the optical disk the coherency of the laser beam is reduced. This is accomplished by one or more of the following techniques: passing the laser beam through a multi-mode optical fiber, combining laser beams from multiple independent laser sources, and modulating the laser operating current at high frequency.
