RFID transducer alignment system
First Claim
1. An apparatus for aligning two devices, comprising:
- a transponder configured to emit an electromagnetic force within a predetermined area of alignment;
a tag configured to emit a radio frequency signal when excited by the electromagnetic force from the transponder; and
a reader configured to detect the signal from the tag.

Abstract
A radio frequency identification (RFID) system having the capacity to detect the parameter of alignment, wherein the system may be used with hand-held, fixed-in-place, stationary and permanently mounted apparatus. The system includes an RF transponder configured for use with dental x-ray, medical imaging and digital radiography apparatus The system may include a multiplicity of RF transponder carrier transmit/data receive coils, each resonant to the same or differing frequencies. An RF tag, an RF transponder and an x-ray film holder are configured to be critically aligned to a dental x-ray machine head apparatus, rendering repeat imaging unnecessary. The x-ray head apparatus may be further configured to automatically obtain a desired x-ray image or configured so that the device cannot activate and provide a radiograph until alignment to an RF tag device has occurred.
