  • Publication number: 20080072326
    Abstract: A method of progressive response for invoking and suspending blocking measures that defend against network anomalies such as malicious network traffic so that false positives and false negatives are minimized. When an anomaly is detected, the detector notifies protective equipment such as a firewall or a router to invoke a blocking measure. The blocking measure is maintained for an initial duration, after which it is suspended while another test for the anomaly is made. If the anomaly is no longer evident, the method returns to the state of readiness. Otherwise, a loop is executed to re-applying the blocking measure for a specified duration, then suspend the blocking measure and test again for the anomaly. If the anomaly is detected, the blocking measure is re-applied, and its duration is adapted. If the anomaly is no longer detected, the method returns to the state of readiness.

  • Patent number: 7132990
    Abstract: A vertically integrated Ka-band active electronically scanned antenna including, among other things, a transitioning RF waveguide relocator panel located behind a radiator faceplate and an array of beam control tiles respectively coupled to one of a plurality of transceiver modules via an RF manifold. Each of the beam control tiles includes a respective plurality of high power transmit/receive (T/R) cells as well as dielectric waveguides, RF stripline and coaxial transmission line elements. The waveguide relocator panel is preferably fabricated by a diffusion bonded copper laminate stack up with dielectric filling. The beam control tiles are preferably fabricated by the use of multiple layers of low temperature co-fired ceramic (LTCC) material laminated together.

  • Patent number: 4686378
    Abstract: An apparatus is disclosed for generating thermal and electrical energy outputs in response to thermal and electrical load requirements imposed thereon. The apparatus includes a variable speed power source and a mechanism for transferring thermal energy from the power source a coolant fluid. A generator is also provided and is driven by the power source to produce electrical energy for the electrical load. The output frequency of the generator is independent of the speed of the power source. A mechanism is also provided for extracting thermal energy from the coolant fluid and directing the thermal energy to the thermal load. Finally, a device is included for monitoring the loads and controlling the thermal and electrical outputs in response to the loads by independently varying the speed of the power source and the output frequency of the generator to provided desired thermal and electrical energy outputs.
