Wireless Data Transmission via Inductive Coupling Using di/dt as The Magnetic Modulation Scheme Without Hysteresis

摘要

The disclosed couplers operate in a “near field” mode, meaning energy, whether used to transmit data or power, is transferred through magnetic induction using a ∂i/∂t circuit (meaning a change in current over a change in time), such as by using inductive transmission and receive coils in which resistors and/or other components such as diodes are placed into series and/or in parallel with the coils and used to control the shape of the pulse, e.g. its voltage and/or frequency. In embodiments, no hysteresis circuit is required for data transmission.
