  • Patent number: 11070085
    Abstract: Aspects of the subject disclosure may include, supplying an alternating voltage waveform to a winding coupled to a magnetic core of an inductive power supply to regulate an alternating magnetic flux in the magnetic core. The alternating voltage waveform can be generated by selectively enabling one or more switches coupled to a storage device. The subject disclosure may further include configuring the one or more switches according to a configuration during a portion of a period of the alternating voltage waveform, and measuring a characteristic of an alternating current flowing in a conductor coupled to the magnetic core during the portion of the period of the alternating voltage waveform. Other embodiments are disclosed.

  • Patent number: 10784721
    Abstract: Aspects of the subject disclosure may include, regulating an alternating magnetic flux in a magnetic core having a first portion separable from a second portion of the magnetic core. The regulation of the alternating magnetic flux causes a coupling force between the first portion of the magnetic core and the second portion of the magnetic core. Responsive to detecting a signal, modifying the regulation of the alternating magnetic flux to reduce the coupling force between the first portion of the magnetic core and the second portion of the magnetic core. Other embodiments are disclosed.

  • Patent number: 10694379
    Abstract: Aspects of the subject disclosure may include, for example, a method for use in a waveguide system that includes: receiving a wireless authentication request from a communication device, the wireless authentication request including a fiber authentication key; comparing, by the waveguide system, the fiber authentication key to fiber authentication data of the waveguide system to determine when the fiber authentication key is authenticated, wherein the fiber authentication data corresponds to a microwave fiber of the waveguide system; and when the fiber authentication key is authenticated, enabling communications with the communication device, wherein the communications include generating, by the waveguide system and in response to first wireless signals received from the communication device, first electromagnetic waves on a surface of a transmission medium, and wherein the first electromagnetic waves have a frequency within a microwave frequency range.

  • Patent number: 10326494
    Abstract: Aspects of the subject disclosure may include, a transmission medium having a first end configured to be coupled to a first port of the launching device, wherein electromagnetic waves are induced by the launching device on a surface of the transmission medium, wherein the electromagnetic waves are bound to the surface of the transmission medium, and wherein the electromagnetic waves propagate without requiring an electrical return path to a second end of the transmission medium. A short circuit, coupled to the second end of the transmission medium, reflects the electromagnetic waves back to the first end of the transmission medium for reception by the launching device as reflected electromagnetic waves at the first port to facilitate a de-embedding of the launching device. Other embodiments are disclosed.
