Abstract: A non-interfering multipath communication technique establishes a base transmit and receive period for a variety of spaced apart transceiver devices of a base station and communicates between at least one field station and the base station through those transceiver devices; a period of the base station is allocated amongst the transceiver devices to maintain the non-interfering multipath communication between the at least one field station and the base station.

Abstract: An electrochemical process and apparatus utilizing a positive and negative electrode. A current is periodically provided in a first direction between the electrodes through the electrolyte of the electrochemical process. The direction of the current is periodically reversed through the electrolyte to repolarize the electrodes, to at least decrease the electric double layer at the electrodes, and to exercise the electrolyte. The current is changed in response to voltage changes occuring across the electrodes caused by perturbations in the electrochemical process itself where the slope of the function representing the current change with respect to a voltage change caused by the perturbations is sufficiently large to enhance the repolarizing, the decreasing of the electric double layer and the exercizing of the electrolyte to thus effect improvement in the electrochemical process.
