Encoding apparatus and method of using the same
First Claim
1. An apparatus for preparing media, the media including a plurality of encodable objects spaced from one another along a length of the media, the apparatus comprising:
- a media path along which the media travels;
a write subsystem configured to wirelessly transmit information for successively encoding the encodable objects as each of the encodable objects is proximate a first position along the media path;
a read subsystem configured to read information encoded in at least one of the encodable objects, if any, and to provide a signal indicative of whether the write subsystem has encoded the information in at least one of the encodable object; and
a control subsystem communicatively coupled to the write subsystem and the read subsystem and configured to advance the media along the media path in response to the signal from the read subsystem indicating that the write subsystem has encoded the information on a respective one of the encodable objects and to wirelessly retransmit the information at a higher power level in response to the signal from the read subsystem indicating that information previously transmitted by the write subsystem was not encoded on the respective one of the encodable objects.

Abstract
A media processing apparatus includes a self-calibrating encoding assembly that send read/write inquires to determine appropriate power levels for encoding encodable objects. The apparatus includes a control subsystem that tracks the power levels of the encoding assembly and the corresponding positions of media carrying the encodable objects. The controller then determines an encoding window and an encoding power level at which the encoding assembly encodes an encodable object in the encoding power window without unwanted communication to encodable objects outside of the window.
