Wireless power transfer for consumer applications
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.
1. An RF power system comprising a power generating unit and a power recovery unit, said power generating unit comprising:
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;
a controller adapted to reduce the RF power radiated if the first amount of RF power reflected by the living organism is greater than a predefined amount; and
said power recovery unit comprising 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, wherein said recovery unit comprises a transmitter transmitting the second amount of power to a receiver disposed in the power generating unit.
2. The RF power generating unit of claim 1 further comprising:
a Doppler radar adapted to detect the living organism.
3. The RF power system of claim 1 wherein the controller is further adapted to reduce the RF power if the second amount of power is greater than the predefined amount.
4. The RF power system of claim 3 wherein the recovery unit further comprises an accelerometer.
5. The RF power system of claim 3 wherein the recovery unit further comprises a gyroscope.
6. The RF power system of claim 3 wherein the recovery unit further comprises a magnetometer.
7. An RF power system comprising:
a power generating unit comprising 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;
a power recovery unit comprising 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; and
a controller adapted to cause the RF power radiated by the RF power generating unit to decrease if both the first amount and the second amount are greater than the predefined amount.
