Patent 6918762 was granted and assigned to Kerr Corporation on July, 2005 by the United States Patent and Trademark Office.
The invention relates to light-generating instruments, which are small, compact and convenient to use. More particularly, the light-generating instruments are generally powered by air, electricity, or light provided by the operating unit, such as the dental chair. Air, electricity, and light provided by the dentist's chair allow for convenience to the dentist while eliminating potential risks and hazards associated with use of an electrical cord to power the instrument.
