    • An electric power generating buoy capable of generating power by scavenging energy from ocean wave motion. The power generating buoy includes float element adapted to float up and down following wave motion and an electric generator system with a spring loaded spool mechanism adapted to drive the rotor of the electric generator. It also includes an anchor element and a tension element attached to an anchor and the spring loaded spool mechanism and adapted to spin the spring loaded spool mechanism to generate electric current when wave action causes the float element to rise relative to the anchor element. Preferred embodiments of the buoy will deliver a minimum of 100 Watts of average power from the wave motion characteristic of moderate sea state (sea state 3), with less power from slight sea state (sea state 2) and more power from higher sea states. The basic power generation scheme will rely on harnessing the mechanical energy of the wave as it repeatedly pushes the buoyant surface float against a ballast force through the distance corresponding to the wave height.

Each of two communicating antennas is equipped with a telescopic camera connected to a processor programmed to recognize landscape images. The processors are programmed to remember the pattern of the landscape as it appears when the antennas are aligned.

Each of the two transceivers has a primary tunable oscillator providing a basic frequency signal that is precisely the same for both transceivers. Preferably the primary tunable oscillator in one of the transceivers, the slave oscillator, is slaved to the primary tunable oscillator, the master oscillator, in the other transceiver and the two transceivers are locked in frequency and phase. Also preferably the master oscillator is frequency controlled to maintain a constant number of wavelengths in the millimeter wave radio beams between the two transceivers, at least for periods of time permitting substantial data transmission without change in the number of wavelengths. In both transceivers a center frequency is generated by frequency multiplication and mixing of harmonics of the basic frequency signal generated by the transceiver's primary tunable oscillator. Preferred embodiments are designed to operate at frequencies above 60 GHz. In a particular preferred embodiment the center frequency for the first transceiver is about 73.5 GHz and the center frequency for the second transceiver is about 83.3 GHz. Embodiments of the present invention include automatic transmit power control, (preferably about 20 db of it, permitting operation at about 1 percent to 100 percent of maximum transmit power) for assuring adequate signal transmission in a wide variety of atmospheric conditions but not excessive power that might interfere with other links at the same frequencies. The narrow beam widths of these transceivers at about 0.5 degrees using a two-foot diameter antenna and the above transmit power control permit a large number of these transceivers to operate in the same region using the same frequencies.
