Abstract: Powerline communication networks can be subject to burst interference resulting in loss of throughput and data corruption. A transmitting network device and a receiving network device of a powerline communication network can be configured to select a best performing powerline terminal coupling configuration for powerline communications. The transmitting network device can determine performance measurements associated with each of a plurality of powerline communication channels. The transmitting network device can select a best performing powerline communication channel based on the performance measurements, and can provide an indication of the best performing powerline communication channel to the receiving network device. The transmitting and the receiving network devices can each configure their respective terminal connections to switch to the best performing powerline communication channel.

Abstract: A suppressor for reducing the muzzle blast of firearms or the like. Several separate absorbent elements are aligned in tandem within a tubular housing, and adjacent absorbent elements are separated by triangular baffles which expose end portions of adjacent absorbent elements. These exposed end surface portions enhance dispersion of propellant gases into and through the absorbent elements. The absorbent elements preferably are made of a knitted ferrous or non-ferrous wire mesh, providing a number of tortuous paths for gas dispersion into the absorbent elements and lowering the temperature of the gases to reduce the noise of the muzzle blast.
