17. A ring illumination system comprising:
-
a light diffusing layer integral with a front cover of a surgical machine; a light refracting layer integral with the front cover of the surgical machine, the light refracting layer comprising a set of prisms arranged in a generally circular pattern; and a printed circuit board located behind, close to, and generally parallel with the front cover of the surgical machine, the printed circuit board comprising an RFID reader antenna located on a face of the printed circuit board closest to the front cover of the surgical machine, the printed circuit board further comprising a set of light emitting diodes located on a face of the printed circuit board furthest from the front cover of the surgical machine, the printed circuit board further comprising a set of openings to allow light from the light emitting diodes to reach the light refracting layer; wherein the light from the light emitting diodes is refracted by the light refracting layer and is diffused by the light diffusing layer to form a generally circular ring of light visible from the front cover of the surgical machine.
