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.

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.

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.

Abstract: A solid state x-ray detector which is a two-dimensional array of individual pixel elements is described. The hybrid semiconductor construction produces detector elements with high spatial resolution (<30 microns), high sensitivity to the entire x-ray spectrum, and frame rates greater than 1000 Hz. In a biomedical application these arrays provide high quality real time digital radiographic images that are directly coupled to an image processing system for image enhancement and computer aided diagnosis. In an alternative embodiment of the invention, the hybrid construction incorporated into an automated manufacturing process facilitates the real time, nondestructive, x-ray examination of manufactured objects during the production process. Structural defects in inorganic objects under test are identified in real time during the manufacturing process are corrected when feedback signals are generated from the electronic image data generated during the nondestructive test process.
