An improved ocean energy converter having a semi-submerged device designed to harvest energy from the ocean. The fast macrodiversity switching dynamically switches radio links used for traffic and control channels for a mobile station among a number of base transceiver stations without switching the radio resource, using the same frequency and time slot combination in an environment where interleaving is occurring. The portable phone determines whether to transmit the data to the slave by Bluetooth\u2122 wireless communication. The first amplification stage is disposed within the housing assembly adjacent to the piezo-electric element and is adapted to amplify the input stroke from the piezo-electric element to a first magnitude. Edges of the resin plies and metal sheets are interleaved to form a composite-to-metal joint connecting the resin plies with the metal sheets.
