Filed:

Jul 3, 2001

Appl. No.:

09/898244

Assignee:

Avanex Corporation - Fremont CA

International Classification:

H01S 300

US Classification:

359334, 359337, 3593414

Abstract:

The present invention provides a hybrid Raman/EDFA optical amplifier that utilizes a first optical detector that generates a first electrical or electronic signal that is proportional the combined optical power of the signal light and the leaked pump laser light, a second optical detector that generates a second electrical or electronic signal that is proportional to the power of the pump laser light and an electronic subtraction circuit that receives the first and second electrical or electronic signals and generates a difference signal that is proportional to only to the optical power of the signal light and insensitive to the power of the Raman pump laser light. The difference signal is utilized by an EDFA control circuit to control and/or adjust the operation of the EDFA based upon changes in the power of the input optical signal.

International Classification:

G06F017/30

US Classification:

707/104100, 707/001000, 701/208000, 707/010000

Abstract:

A method and system for taking data in any format, either in a database such as Oracle, SQL, or another common database, and dynamically combining it with geographic information, i.e., a map or aerial or satellite photograph or other image, allows the user to display that data on a map, to analyze that data geographically or spatially or merely to provide information from certain locations. The result can be presented to the user as a single image that can, if desired, be interactive, allowing the user to access additional information not displayed or not capable of displaying on the map.

Appl. No.:

11/099400

Inventors:

Gang Li - San Jose CA, US

International Classification:

H04N 9/74
G09G 5/00

US Classification:

345660000, 348581000

Abstract:

A video conversion system receives a luminance image and a chrominance image of a video image. The video conversion system vertically scales the luminance image and the chrominance image. The video conversion system then horizontally scales the video image based on the vertically scaled luminance image and the vertically scaled chrominance image to generate a scaled video image.

US Classification:

424 937, 435325

Abstract:

The present invention provides a selected population of neural cells, including neural stem cells, neural progenitor cells, neural precursor cells, and progeny thereof, which neural cells are selected for an apoE4 phenotype. In some embodiments, the neural cells are further selected for an apoE3 phenotype. The selected population of neural cells is useful in treating various disorders, such as neurodegenerative disorders and demyelination diseases. The present invention further provides methods of treating neurodegenerative disorders and demyelinating diseases, generally involving administering a subject selected cell population.

International Classification:

E21B 49/00
G01V 5/00

US Classification:

7315202, 250256

Abstract:

A method and apparatus for determining a stress field in a subterranean formation include deploying a stress measurement tool on a tubular string, opening at least three fractures in three different radial directions in the subterranean formation, and closing the at least three fractures. The at least three fractures are reopened while measuring stress and strain conditions. From the reopening, a tangential stress component for each of the at least three fractures is determined. From the tangential stress components and radial directions of the at least three fractures, the stress field of the subterranean formation is determined.
