Abstract: The present invention relates to a method for optimizing the positioning of high sensitivity receiver front-ends 5 in a mobile telephony network 1 of the CDMA type comprising a plurality of cells 2. The method comprises the following steps: defining a first and a second cell indicator Vcell, V2; defining a first and a second threshold value L and L2; comparing said first cell indicator Vcell with a first threshold value L and said second cell indicator V2 with a second threshold value L2; associating with a first category a plurality of first cells 2a having said first cell indicator Vcell greater than said first threshold value L or said second cell indicator V2 greater than said second threshold value L2; positioning a plurality of high sensitivity receiver front-ends 5 substantially in all said plurality of first cells 2a.

Abstract: A communication network includes a plurality of antennas and includes among the antennas at least one reconfigurable antenna adapted to serve communication traffic in a respective coverage area, the reconfigurable antenna having a radiation diagram exhibiting a plurality of selectively adjustable gain values for a set of directions, each direction in the set defining a propagation path between the antenna and a portion of the coverage area, determining, for each direction in the set, at least one value of communication traffic and at least one attenuation value over the propagation path, and selectively and independently alloting to each direction in the set a respective gain value as a function of at least one of the value of communication traffic and the attenuation value determined for that direction. The arrangement is adapted for use in communication networks such as second and third generation mobile communication networks employing electrically controllable antennas.

Abstract: The present invention is directed to a mobile hammermill apparatus for pulverizing and compacting waste and soil in road construction, disaster cleanup, forestry, agriculture, and particularly at landfill sites, in a single operation. The mobile apparatus achieves superior compaction densities by using a plurality of compacting and pulverizing members that are mounted rotatably on a plurality of eccentrically mounted shafts running parallel to a main shaft, which rotates to cause the compacting and pulverizing members to impact the surface beneath the apparatus. The rear of the apparatus is supported by a compactor drum which provides a shield to prevent debris from being ejected from the rear of the compactor and provides a mass to compact the pulverized waste and soil as the apparatus is moved across the surface of the landfill.

Abstract: The present invention is directed to an apparatus and method for compacting and pulverizing waste and soil, including a mechanism for cutting wire, tubing, hoses, plastics, carpet, mattresses, and other like materials that tend to be present at landfill and other waste sites and that can interfere with the operation of a compacting and pulverizing apparatus. The mobile compactor, pulverizer and cutting method achieves superior performance in terms of increased compacting ability by using a plurality of compacting and pulverizing members that are mounted rotatably on a plurality of rods running parallel to a main shaft, which compacting and pulverizing members rotate about the main shaft during operation to compact and pulverize waste and soil and other materials.
