Appl. No.:

09/965033

Inventors:

Yu Wang - La Crescenta CA, US

Assignee:

California Institute of Technology - Pasadena CA

International Classification:

G02B 1/10

US Classification:

359585, 359578, 359589, 359584, 349105, 349106, 345 88, 348744

Abstract:

Devices based on surface plasmon filters having at least one metal-dielectric interface to support surface plasmon waves. A multi-layer-coupled surface plasmon notch filter is provided to have more than two symmetric metal-dielectric interfaces coupled with one another to produce a transmission spectral window with desired spectral profile and bandwidth. Such notch filters can form various color filtering devices for color flat panel displays.

Appl. No.:

10/612442

Inventors:

Yu Wang - La Crescenta CA, US

Assignee:

The United States of America as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC

International Classification:

G02B 6/06

US Classification:

25022728, 25022729, 2502272, 250216

Abstract:

A miniature, ultra-high resolution, and color scanning microscope using microchannel and solid-state technology that does not require focus adjustment. One embodiment includes a source of collimated radiant energy for illuminating a sample, a plurality of narrow angle filters comprising a microchannel structure to permit the passage of only unscattered radiant energy through the microchannels with some portion of the radiant energy entering the microchannels from the sample, a solid-state sensor array attached to the microchannel structure, the microchannels being aligned with an element of the solid-state sensor array, that portion of the radiant energy entering the microchannels parallel to the microchannel walls travels to the sensor element generating an electrical signal from which an image is reconstructed by an external device, and a moving element for movement of the microchannel structure relative to the sample. Discloses a method for scanning samples whereby the sensor array elements trace parallel paths that are arbitrarily close to the parallel paths traced by other elements of the sensor array.

International Classification:

G06F 12/02

US Classification:

711159, 711112, 711161, 711162

Abstract:

In one embodiment of the invention, a method is provided for retrieving certain electronic information previously stored on certain storage media after a threshold set in the storage retention criteria has been exceeded in an electronic information storage system that stores electronic information on storage media in accordance with a storage retention criteria is provided. The method includes storing a record in a memory associated with a system manager that assigns the storage retention criteria to the certain electronic data, designating the storage media available for overwrite after the threshold set in the storage retention policy has been exceeded, identifying the certain storage media available for overwrite, and retrieving information from the certain media after the threshold set in the storage retention policy has been exceeded.

Yu Wang - La Crescenta CA, US

International Classification:

G06K 9/40
G06K 9/36
G06K 9/32

US Classification:

382254, 382280, 382299

Abstract:

The present disclosure includes an image processing technique that is capable to increase spatial resolution of single frame images beyond diffraction limit. If an image is taken by diffraction limited optical system with regularly spaced pixel detectors, and if the spacing of pixels of the detectors is much small than the diffraction pattern, then the spatial resolution of the image can be increased beyond the diffraction limit by using neighboring-pixel-optical-transfer-function (NPOTF) in Fourier Domain with periodical boundary conditions.

US Classification:

709224, 709223, 714 41

Abstract:

A data server computer ring including first and second data server computers, and any number of further data server computers. The data server computer “ring” can include any configuration in which the data server computers are connected together by communications links. The first and second data server computers are programmed by a computer program so that when one of the first and second data server computers is not operating, so that it is a non operating data server computer, the other of the first and second data server computers takes over one or more functions normally performed by the non operating data server computer.

International Classification:

G06F 13/00

US Classification:

718105, 711154

Abstract:

A resource allocation system begins with an ordered plan for matching requests to resources that is sorted by priority. The resource allocation system optimizes the plan by determining those requests in the plan that will fail if performed. The resource allocation system removes or defers the determined requests. In addition, when a request that is performed fails, the resource allocation system may remove requests that require similar resources from the plan. Moreover, when resources are released by a request, the resource allocation system may place the resources in a temporary holding area until the resource allocation returns to the top of the ordered plan so that lower priority requests that are lower in the plan do not take resources that are needed by waiting higher priority requests higher in the plan.
