    Abstract: The invention relates to a directional coupling communication apparatus where the coupling impedance can be easily matched to reduce reflections, and thus, the speed of communication channels is increased as compared to that with inductive coupling, and at the same time, the reliability of communication is improved by increasing the signal intensity. Modules having a coupler where an input/output connection line is connected to a first end, and either a ground line or an input/output connection line to which an inverse signal of a signal to be inputted into the input/output connection line connected to the above-described first end is inputted is connected are layered on top of each other so that the couplers are couplers to each other using capacitive coupling and inductive coupling.

    Abstract: Coupled coil systems and methods are disclosed in which transmitter and receiver inductors, or coils, are coupled in a configuration for wirelessly transferring power among them. In preferred implementations, power may be transmitted and received using temporarily paired coupled coils. One preferred aspect of the invention is that the coils are not permanently affixed in physical proximity to one another, but can be moved and/or interchanged, and that the coils may be used to transmit or receive power based on their real-time relationships to other coils.

    Abstract: A primary side wireless power transmitter inductively couplable to a secondary side wireless power receiver for receiving communications from the secondary side wireless power receiver through the inductive coupling having a primary side tank circuit receiving a signal from the secondary side wireless power receiver. A phase delay or time delay circuit generates a fixed delay clock signal from a signal utilized to excite the primary side tank circuit. A sample and hold circuit samples a tank circuit voltage utilizing the fixed phase or time delayed clock signal. A comparator is coupled to an output of the sample and hold circuit for extracting data or commands from the signal stream. A method of operating a primary side wireless transmitter inductively coupled to a secondary side wireless power receiver for supplying power to the wireless power receiver to power a load coupled to the receiver is also disclosed.

    Abstract: A method for transmitting data and a wireless charging equipment using the same are disclosed. When the wireless charger transmits data, an output current of the wireless charger is controlled at a preset current value so that there is a higher variation in amplitude of a current or a voltage on an inductive element to thereby enable a signal receiver to demodulate the signal. At the end of data transmission, the output current is resumed consistent with a driving current of the load at the moment. The present disclosure can address the problem of impossible normal communication in the wireless charger at the circumstance of a very low driving current of the load without any increase in cost and complexity of the circuit.
