    Abstract: PROBLEM TO BE SOLVED: To perform wireless power transmission at levels that induce high power transfer and/or high efficiency of coupling.SOLUTION: A wireless power system comprises: a signal generator 104 which has a connection to a source 102 of power and creates a modulated signal at a first frequency; a transmitting antenna 110 which transmits a magnetic field having the first frequency and based on power created by the signal generator 104; a receiving antenna which receives a magnetic power signal created by the transmitting antenna 110 and is more than 1 m distant from the transmitting antenna 110; and a load receiving part 160 which receives power from the receiving antenna. Transfer efficiency between the transmitting antenna 110 and the receiving antenna is greater than 25% at 1 m of distance between the transmitting antenna 110 and the receiving antenna.

    Abstract: PROBLEM TO BE SOLVED: To provide wireless power range increase using a parasitic antenna.SOLUTION: Wireless power transfer is created using a first antenna that is a part of a magnetic resonator, to create magnetic field in an area of the first antenna. One or more parasitic antennas repeat that power to create local areas where the power is more efficiently received.

    Abstract: Sistemas, métodos y aparatos para detector objetos extraños. En un aspecto, un aparato para detectar la presencia de un objeto. El aparato incluye un circuito de resonancia con una frecuencia de resonancia. El circuito de resonancia incluye un circuito de sentido que incluye una estructura conductora eléctricamente. El aparato además incluye un circuito de acoplamiento acoplado al circuito de sentido. El aparato además incluye un circuito de detección acoplado al circuito de sentido mediante el circuito de acoplamiento. El circuito de detección está configurado para detectar la presencia del objeto en respuesta a detector una diferencia entre una característica medida que depende de una frecuencia a la cual el circuito de resonancia está resonando y a una característica correspondiente que depende de la frecuencia de resonancia del circuito de resonancia. El circuito de acoplamiento está configurado para reducir una variación de la frecuencia de resonancia por el circuito de detección en ausencia del objeto.
