Abstract: An antenna beam tracking system has dynamic interference reduction. The system includes antennas that can form multiple beams, each beam of which can continually track or point its beams independently in various angular directions. A first beam continually tracks and receives (downlink) signals from a desired source or node such as a satellite or terrestrial node which generally has an apparent motion relative to the antenna. A second beam continually tracks and receives potentially harmful interference signals that may arise from different directions. The signals of the second beam are dynamically coupled to the signals in the first beam in such a manner as to effect cancellation or substantial reduction of the interference.

The evaporation chamber includes a heating element and a porous support surrounding the heating element. The porous support carries thereon a working fluid, and the heating element vaporizes the working fluid to form vapor within the evaporation chamber. The porous support may include a portion which extends into a working fluid reservoir.

Abstract: A computer receives a write request including an offset within a virtual disk. The computer writes the data block to a remote platform and calculates a hash value of the data. If the hash value does not exist in a first table of a block cache of the computer, the computer adds a pair to the first table: hash value/block cache data offset. Next, the computer adds a pair in a second table of the block cache: virtual disk offset of the data/hash value. A read request uses these tables to find the data in the cache without accessing the platform. The read consults the second table to find the hash value corresponding to the virtual disk offset of the block. The hash value is a key into the first table to find the block cache data offset of the data; the data is read from the cache.
