A dialysis valve includes a tube attached between an artery and a vein which, when elongated, simultaneously narrows in diameter at at least one location. The electronic device operates in a scan event mode automatically mapped an incoming event to the TDO pin. An embodiment involving co-located separate transmit and receive antennas is used to minimize the power requirements for the multi-port junction, whereas in a third embodiment, an array of transmitreceive antennas is used, fed by the same RF source but in which digitally-controlled phase shifters are used for beam-forming purposes. In one embodiment, the method does not include the physical removal of any acid functional monomers or polymerization products. Also provided are electrolytes and batteries produced from these salts.
