CONTACTLESS COMMUNICATION SIGNAL TRANSFER
First Claim
1. A system for transferring information from a first apparatus to a second apparatus, comprising:
- a transmitter operably coupled to the first apparatus, the transmitter comprising;
an electrically conductive first member comprising a first channel, andan electrically conductive first element positioned within the first channel without a ferromagnetic material disposed between the first element and the first channel, the first element configured to generate a first electric field in response to a first current flow in the first element; and
a receiver operably coupled to the second apparatus, the receiver comprising;
an electrically conductive second member comprising a second channel facing the first channel, andan electrically conductive second element positioned within the second channel without a ferromagnetic material disposed between the second element and the second channel, the second element configured to have a second current induced in the second element based upon the first electric field, whereby information is derived from the second current.

Abstract
Among other things, one or more techniques and/or systems are described herein for transferring communication information between a stationary unit and a movable (e.g., rotating) unit, or between two movable units without contact between the units. A transmitter is configured to translate digital information into an analog signal which may be fed to an input coupler positioned within a channel of an electrically conductive member (e.g., on a first unit, such as a stationary unit). The current of the signal induces a signal in an output coupler (e.g., on a second unit, such as a movable unit). Voltage characteristics of the induced signal (e.g., which substantially correspond to voltage characteristics of the signal fed into the input coupler) may subsequently be used to reconstruct the digital data at a receiver. In this manner, information can be communicated between two non-contacting units.

20. A method for communicating information between a first apparatus and a second apparatus, comprising:
-
converting a digital signal to an analog signal comprising a first current; passing the first current through an electrically conductive first element situated within a first channel of a first electrical shield; inducing a second current in an electrically conductive second element situated within a second channel of a second electrical shield, the second channel facing the first channel, and the second element separated from the first element by an airgap such that the first element is not physically coupled to the second element; and translating the second current to digital data.
