  • Patent number: 7636318
    Abstract: A real-time network-analysis system comprises a network appliance and a plurality of management devices. The network appliance continuously monitors an object network and synthesizes a current network image comprising contemporaneous indicators of connectivity, occupancy, and performance of the object network. A management-client device may gain access to the network image for timely control and for use in producing long-term network-evolution plans. To enable the creation of a real-time network image, optimized topology synthesis algorithms are devised to minimize the computational effort. The real-time network-analysis system is adapted for use with an object network employing a variety of routing protocols, such as link-state protocols, and network-management protocols, such as the Simple-Network-Management protocol.

  • Patent number: 7579666
    Abstract: The present invention is directed toward a detector structure, detector arrays, a method of detecting incident radiation, and a method of manufacturing the detectors. The present invention comprises several embodiments that provide for reduced radiation damage susceptibility, decreased affects of cross-talk, and increased flexibility in application. In one embodiment, the present invention comprises a plurality of front side illuminated photodiodes, optionally organized in the form of an array, with both the anode and cathode contact pads on the back side. The front side illuminated, back side contact photodiodes have superior performance characteristics, including less radiation damage, less crosstalk using a suction diode, and reliance on reasonably thin wafers. Another advantage of the photodiodes of the present invention is that high density with high bandwidth applications can be effectuated.

  • Patent number: 7506847
    Abstract: A hexapod machine is disclosed in which six adjustable length struts couple to a controllably moveable platform at three triangularly spaced locations at each of which a pair of struts couple together and to the platform at a bifurcated universal joint. The struts extend away from the platform and through machine nodes defined at triangularly spaced-apart locations in a machine sub-frame, and at each such node a strut extending from one platform location and the next adjacent strut from the next adjacent platform location come together and cross each other in respective hemispheres of a bifurcated sphere journalled for multidirectional pivotal movement in a socket in the sub-frame. The hemispheres each contain a motor which is frictionally engaged with the respective strut so as to enable it to be driven through the hemisphere to adjust its effective length. By control of the motors, the platform position and orientation can be adjusted in space.
