What is claimed is: 1. A ring illumination system comprising: an illumination ring integral with a front of a surgical machine, the illumination ring comprising a light refracting layer; and a printed circuit board located behind and close to the front of the surgical machine, the printed circuit board comprising an RFID reader antenna and a light source; the printed circuit board further comprising a set of openings to allow light from the light source to reach the illumination ring; wherein light emitted by the light source travels through the illumination ring and is visible from the front of the surgical machine. 2. The system of claim 1 further comprising: a light diffusing layer disposed on the front of the surgical machine. 3. The system of claim 1 wherein the printed circuit board is located on a plane generally parallel with the front of the surgical machine. 4. The system of claim 1 wherein the face of the illumination ring exposed on the front of the surgical machine is textured. 5. The system of claim 1 wherein the light source is a set of light emitting diodes located on a face of the printed circuit board furthest from the front of the surgical machine. 6. The system of claim 1 wherein the RFID reader antenna is located on a face of the printed circuit board closest to the front of the surgical machine. 7. The system of claim 1 wherein the light refracting layer is a set of prisms. 8. A ring illumination system comprising: a module having a front face and a back face; an illumination ring integral with the module and extending from the front face of the module to the back face of the module; and a printed circuit board located behind and close to the back face of the module, the printed circuit board having an RFID reader antenna and a light source; the printed circuit board further comprising a set of openings to allow light from the light source to reach the back face of the module; wherein light emitted by the light source travels through the illumination ring and is visible from the front face of the module. 9. The system of claim 8 wherein the illumination ring comprises a set of prisms for refracting light emitted from the light source. 10. The system of claim 8 further comprising: a light diffusing layer disposed on the front face of module. 11. The system of claim 8 wherein the front face of the module is textured. 12. The system of claim 8 wherein the printed circuit board is located on a plane generally parallel with the front face of the module. 13. The system of claim 8 wherein the light source is a set of light emitting diodes located on a face of the printed circuit board furthest from the back face of the module. 14. The system of claim 8 wherein the RFID reader antenna is located on a face of the printed circuit board closest to the back face of the module. 15. The system of claim 8 wherein the illumination ring diffuses light from the light source. 16. The system of claim 8 wherein the light source is capable of producing at least two different colors of light. 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.
