Abstract
An embodiment of a light powered transmitter configured for broadcasting an electromagnetic control field to a region is provided. The transmitter includes a housing having a longitudinal axis. The housing includes a photovoltaic cell configured to generate electrical power in response to light and a rechargeable power source configured to store at least a portion of the power generated by the photovoltaic cell. The housing also includes an electromagnetic transmitter and a directional antenna. The directional antenna can be configured to broadcast an electromagnetic (e.g., radio-frequency) control field to a region. The directional antenna can be rotatably mounted in the housing such that the antenna can be rotated around the longitudinal axis. The housing can further include a transparent or translucent optical element configured to receive the light and converge at least a portion of the light onto the photovoltaic cell.
