Patent
System and method for launching guided electromagnetic waves with impedance matching
TL;DR: In this paper, a system includes an impedance matching circuit that includes one or more adjustable circuit elements, wherein the impedance-matching circuit receives an input signal and generates an output signal in response to the input signal.
Patent
Methods and apparatus for regulating a magnetic flux in an inductive power supply
Giovanni Vannucci,Paul Shala Henry,Thomas M. Willis,Farhad Barzegar,Irwin Gerszberg,Robert Bennett,Harold Lee Rappaport,Donald J. Barnickel +7 more
TL;DR: In this paper, an alternating voltage waveform is generated by selectively enabling one or more switches coupled to a storage device, which can be configured according to a configuration during a portion of a period of the waveform and measured a characteristic of an alternating current flowing in a conductor coupled to the magnetic core.
Patent
Methods and apparatus for coupling and decoupling portions of a magnetic core
Giovanni Vannucci,Farhad Barzegar,Harold Lee Rappaport,Irwin Gerszberg,Thomas M. Willis,Paul Shala Henry,Robert Bennett,Donald J. Barnickel +7 more
TL;DR: In this article, the authors describe a magnetic core having a first portion separable from a second portion of the magnetic core, and modify the regulation of the alternating magnetic flux to reduce the coupling force between the first portion and the second portion.
Patent
Guided wave launcher with aperture control and methods for use therewith
TL;DR: In this article, a plurality of transceivers is configured to generate first signals, in response to control signals, which are then used to generate a first guided electromagnetic wave that is guided by a surface of a transmission medium and propagates along the transmission medium.
Patent
Guided wave launcher with lens and methods for use therewith
TL;DR: In this article, a dielectric lens is configured to guide the first near field signals to a surface of a transmission medium, inducing a first guided electromagnetic wave that is guided by the surface of the transmission medium and propagates along the transmission channel without requiring an electrical return path.
