Filed:

Feb 1, 1999

Appl. No.:

09/241201

Inventors:

David Shan-Ming Wang - Fremont CA
P. Robert Hsu - San Jose CA

Assignee:

Sony Corporation - Tokyo
Sony Electronics Inc. - Park Ridge NJ

International Classification:

G06F 1516

US Classification:

709206, 709207

Abstract:

A system allows users to send electronic mail messages having prioritized delivery. A server receives an electronic mail message that contains a specified priority or a specified time frame for delivery. The server determines a time frame for delivery and selects procedures to ensure delivery of the electronic mail message within the determined time frame. The server then provides the electronic mail message to the receiving account within the determined time frame.

Assignee:

Therma-Wave, Inc. - Fremont CA

International Classification:

G02B 900

US Classification:

359797, 359661, 359785

Abstract:

The subject invention relates to broadband optical metrology tools for performing measurements of patterned thin films on semiconductor integrated circuits. Particularly a family of optical designs for broadband, multi-wavelength, DUV-IR (185900 nm) all-refractive optical systems. The designs have net focusing power and this is achieved by combining at least one positively powered optical element with one negatively powered optical element. The designs have small spot-size over the wavelength range spanning 185-900 nm with substantially reduced spherical aberration, axial color, sphero-chromatism and zonal spherical aberration. The refractive optical systems are broadly applicable to a large class of broadband optical wafer metrology tools including spectrophotometers, spectroscopic reflectometers, spectroscopic ellipsometers and spectroscopic scatterometers.

Abstract:

An improved control and monitoring system for managing more than one computer system using a witch with a single connector for keyboard, video and mouse signals for each computer being managed. A notebook style display, keyboard, and pointing device attached to the switch provide a human interface. Each computer is attached to the switch using a cable having a single connector at the attachment point to the switch and separate connectors for keyboard, video, and pointing device signals at the attachment point to each computer, thus allowing a greater density of connections to computers without modifying the computers being controlled and monitored. Even greater densities may be realized by designating one switch as a master and attaching additional switches to the master.

Appl. No.:

10/208323

Inventors:

David Y. Wang - Fremont CA
David M. Aikens - Chester CT

Assignee:

Therma-Wave, Inc. - Fremont CA

International Classification:

G01J 314

US Classification:

356326, 356328

Abstract:

The subject invention relates to the design of a compact imaging spectrometer for use in thin film measurement and general spectroscopic applications. The spectrometer includes only two elements, a rotationally symmetric aspheric reflector and a plane grating. When employed in a pupil centric geometry the spectrometer has no coma or image distortion. Both spherical aberration and astigmatism can be independently corrected. The invention is broadly applicable to the field of optical metrology, particularly optical metrology tools for performing measurements of patterned thin films on semiconductor integrated circuits.

Filed:

Feb 26, 2002

Appl. No.:

10/083213

Inventors:

David S. Wang - Newark CA

Assignee:

Sony Corporation - Tokyo
Sony Electronics Inc. - Park Ridge NJ

International Classification:

G06F 1730

US Classification:

707 3, 725 53

Abstract:

A system and method for effectively implementing a personal channel for interactive television comprises a personal channel manager that may include a configuration module, a search module, and a content packaging module. A system user may utilize the configuration module to perform a personal channel configuration procedure to specify personal channel configuration data for performing a content record search procedure. The search module may manage the content record search procedure according to one or more search parameters that may be defined during the personal channel configuration procedure. The search module may selectively locate and access one or more content records from one or more remote content databases during the foregoing content record search procedure. The content packaging module may then responsively coordinate a content record sorting procedure according to user-specified sorting criteria to thereby organize the located content records into a personal channel program. The personal channel program may then be presented upon a television device for viewing by the system user.

Abstract:

The present invention provides for a method of and apparatus for compressing and uncompressing image data. According to one embodiment of the present invention, the method of compressing a color cell comprises the steps of: defining at least four luminance levels of the color cell; generating a bitmask for the color cell, the bitmask having a plurality of entries each corresponding to a respective one of the pixels, each of the entries for storing data identifying one of the luminance levels associated with a corresponding one of the pixels; calculating a first average color of pixels associated with a first one of the luminance levels; calculating a second average color of pixels associated with a second one of the luminance levels; and storing the bitmask in association with the first average color and the second average color. In one embodiment, the color cell includes a matrix of 4x4 pixels, the bitmask includes 32-bits and each of the color values includes 16-bits such that a compression rate of 4-bits per pixel is achieved. The present invention is particularly applicable to compress texture data such that the texture data can be more efficiently cached and moved during texture mapping.
