Abstract
An RF power system, includes, in part, a power generating and a controller. The power generating unit, includes, in part, a first power detector adapted to detect a first amount of RF power radiated by the RF power generating unit and reflected off a living organism. The controller is adapted to reduce the radiated RF power if the first amount of RF power reflected by the living organism is detected as being greater than a predefined amount. The power generating unit may further include a Doppler radar to detect the living organism. The RF power system may further include a power recovery unit that, in turn, includes a second power detector adapted to detect a second amount of RF power radiated by the RF power generating unit and reflected off the living organism.
