1. A wireless datalink activation system for remote activation of an electrical apparatus using a remote optical data transmitter and a directed beam remote optical emission source, said wireless datalink activation system comprising:

  • a) at least one data receiver for receiving serial digital information from a remote optical data transmitter, said data receiver serving both activation and data/control wireless datalink functions;

    b) a low-power photovoltaic power generation and distribution system, comprising;

    at least one photovoltaic panel for receiving optical power from a directed beam remote optical emission source; and

    power accumulation and distribution means, comprising a micro-power timer integrated circuit, connected to said at least one photovoltaic panel for accumulating power generated by said at least one photovoltaic panel for periodically and intermittently distributing accumulated power in desired quantities; and

    c) a unique signal detector connected to said at least one data receiver and to said power accumulation and distribution means, and being connectable to an electrical apparatus, wherein said periodically and intermittently distributed power enables said unique signal detector to evaluate incoming data received from said at least one data receiver, and upon detection of the receipt of a signal qualifying as a key, thereupon issues a command to said electrical apparatus to initiate uninterrupted data communication from said data receiver.
