Abstract
An apparatus and method of transmitting data between two inductively coupled circuits. The method includes providing a transmitting circuit, providing a receiving circuit spaced from the transmitting circuit, and generating a data signal in the transmitting circuit. The data signal includes a first component representing the data, and a second component identifying a portion of the first component. The apparatus includes a transmitting circuit having a transmitting coil. The transmitting circuit generates electrical energy in the transmitting coil. The apparatus further includes a receiving circuit spaced from and inductively coupled to the transmitting circuit. The receiving circuit includes modulating means for generating a carrier signal including a first component encoding a plurality of consecutive data signals, and a second component identifying the beginning of respective ones of the data signals.
