Abstract
A medical machine includes: an enclosure defining an opening, at least a portion of the enclosure being electrically conductive and acting as a first capacitor plate; a medical device component located inside the enclosure; a window placed adjacent to the opening; a video display with an at least partially conductive case acting as a second capacitor plate; and a dielectric member placed between the first and second capacitor plates, the plates and dielectric member forming a capacitor configured to prevent leakage of electromagnetic energy from the enclosure.

A medical machine comprising:
- an enclosure defining an opening, at least a portion of the enclosure being electrically conductive;
- an electrically operated component capable of generating electromagnetic energy (“EMI”), the component located inside the enclosure;
- a window placed adjacent to the opening;
- a conductive border abutting the conductive portion of the enclosure;
- an insulating border abutting the conductive border;
- and
- a video display including a display portion and an external case, the external case having an electrically conductive surface surrounding the display portion, the electrically conductive surface abutting the insulating border, wherein the conductive border forms at least part of a first capacitor plate and the electrically conductive surface of the video display case forms a second capacitor plate.
