Solar powered transmitter

A light powered transmitter configured for broadcasting an electromagnetic control field to a region, the light powered transmitter comprising:

• a housing having a longitudinal axis, the housing comprising:
• a photovoltaic cell configured to generate electrical power in response to light;
• a rechargeable power source electrically coupled to the photovoltaic cell, the rechargeable power source configured to store at least a portion of the power generated by the photovoltaic cell;
• an electromagnetic transmitter;
• and
• a directional antenna electrically coupled to the electromagnetic transmitter, the directional antenna configured to broadcast an electromagnetic control field to a region, the directional antenna rotatably mounted in the housing such that the antenna can be rotated around the longitudinal axis, wherein the housing further comprises a transparent or translucent optical element configured to receive the light and converge at least a portion of the light onto the photovoltaic cell.

A solar powered transmitter for transmitting a radio-frequency signal, the solar powered transmitter comprising:

• means for transmitting a radio-frequency signal, the transmitting means comprising means for directionally radiating the radio-frequency signal;
• means for generating electrical power from sunlight;
• means for storing electrical power, the power storing means rechargeable by the power generating means;
• means for housing the signal transmitting means, the power generating means, and the power storing means, the housing means having a longitudinal axis, the housing means configured to allow the radiating means to rotate at least partially around the longitudinal axis, the power generating means disposed in the housing means so that the power generating means can receive the sunlight;
• and
• means for mounting the solar powered transmitter, the mounting means configured to allow the transmitter to be rotated around a mounting axis that is non-parallel to the longitudinal axis.
