Appl. No.:

10/126930

Inventors:

Vilas Koinkar - Carlsbad CA
Timothy C. Collins - Carlsbad CA
Joannes M. Costa - Carlsbad CA
Joseph A. Levert - Vista CA

Assignee:

Oluma, Inc. - Carlsbad CA

International Classification:

B24B 4900

US Classification:

451 8, 451460

Abstract:

Fabrication techniques for polishing fibers engaged in grooves on substrates. A protection template assembly is disclosed to protect the unpolished portions of fibers. Chemical mechanical polishing may be used to achieve high fabrication throughput and high polishing uniformity. Optical monitoring may be used to monitor the polishing in real time.

Filed:

Apr 18, 2001

Appl. No.:

09/838707

Inventors:

Bo Pi - Carlsbad CA, US
Timothy Collins - Carlsbad CA, US
Richard Conwell - Del Mar CA, US

International Classification:

H01L033/00

US Classification:

257/088000

Abstract:

An improved semiconductor position-sensitive radiation detection device based on a photodiode array formed in a substrate. In one embodiment, the substrate has a first surface and a second surface opposing the first surface. The first surface is electrically conducting to provide a common bias potential to the photodiodes and is optically transparent to receive input photons to be detected. The device includes a grid of conducting wires formed over and in electrical contact with the first surface and configured to define an array of pixels corresponding to the array of photodiodes. A scintillation array of scintillation elements can be coupled to match the pixels defined by the grid of conducting wires and to convert incident radiation at a first wavelength outside the characteristic spectral response range of the substrate into secondary photons at a second wavelength within the spectral response range of the substrate. The scintillation array includes optically reflective surfaces disposed between the scintillation elements to optically isolate one scintillation element from another.

International Classification:

H04L 29/06

US Classification:

726 11

Abstract:

Methods, apparatus, and computer readable storage media reduce or eliminate network traffic meeting criteria. In some aspects, network traffic transmitted by one or more source nodes to one or more destination nodes may comprise a denial of service attack against the destination node(s). At least a portion of the denial of service attack traffic may be reduced or eliminated with the disclosed methods and apparatus. In one aspect, a method of managing undesirable network traffic transmitted from a source node to a destination node over a communications network includes receiving a notification of a routing rule change, authenticating the notification, determining a network routing rule based on the notification, applying the network routing rule, determining a network path toward the source node, determining an entity based on the network path, and transmitting a notification of the routing rule change to the entity.

Filed:

Sep 22, 1998

Appl. No.:

9/158639

Inventors:

Bo Pi - San Diego CA
Timothy C. Collins - Carlsbad CA
Richard L. Conwell - Del Mar CA

Assignee:

Digirad Corporation - San Diego CA

International Classification:

G01T 1164

US Classification:

2503631

Abstract:

A radiation detection device for gamma radiation is disclosed having an array of crystals optically positioned adjacent an optional collimator, the crystals emitting visible light upon illumination by the incident gamma radiation. An array of photodetectors is optically positioned adjacent the crystal array on the side of the crystal array opposite that of the collimator. A select photodetector in the photodetector array provides an output signal when the select photodetector is illuminated by the visible light. An integrated circuit having an input from the output signals of said array of photodetectors is used to process and output signals indicative of the intensity and position of the gamma radiation.
