  • Patent number: 9413432
    Abstract: Provided is a near field wireless communication apparatus that uses magnetic coupling and a method for operation of the apparatus, in which the magnetic coupling is used to transmit data or clock information with low power and high efficiency. A pulse generator of the near field wireless communication apparatus generates a pulse signal corresponding to transmission digital data to be transmitted. When the transmission digital data is “1,” the near field wireless communication apparatus modulates the data into the pulse signal and transmits the pulse signal. When the data is “0,” the near field wireless communication apparatus does not output the pulse.

  • Publication number: 20160099577
    Abstract: Apparatuses, systems, and methods of wireless power transmission/reception are described. In one wireless power transmission/reception device, a planar resonator capable of generating magnetic fields has one or more ferrite members mounted thereon such that the magnetic fields generated by the planar resonator have an overall direction substantially tilted or parallel to its opening/face, i.e., to the plane of the planar resonator. In a wireless power reception device, the planar resonator generates magnetic fields and an induced current when being resonated by external magnetic fields; in a wireless power transmission device, the planar resonator generates magnetic fields when being supplied with power.
