Title (EN) ELECTRICALLY ISOLATED ILLUMINATION CONTROL FOR DENTAL DRILL
(FR) COMMANDE ELECTRIQUEMENT ISOLEE DE L"ECLAIRAGE D"UNE FRAISE DENTAIRE
Abstract: front page image
(EN)Control means for a fiber optic illumination system are disclosed having a light source and a fiber optics bundle (192) with a proximal end positioned adjacent to said light source and a distal end positionable in the immediate region where light is desired, said control means comprising a control unit (194) whose small size enables the control unit to be positioned so as not to interfere with the normal use of other implements being employed in the dental work area ad having signal generating means (123) including switch means (111) for activating said signal generating means to develop a function control signal, sensing means (124) displaced from and electrically isolated from said signal generating means for generating an activating signal upon receipt of said function control signal, and means (125) responsive to said activating signal for energizing said light source. The control means may comprise means for sensing the presence or absence of light, or means sensitive to other electromagnetic waves.
(FR)Dans un dispositif d"eclairage par fibres optiques comprenant une source de lumiere et un faisceau de fibres (192) dont une extremite est placee adjacente a la source de lumiere et l"autre a proximite immediate de la region a eclairer, les moyens de commande comprennent une unite de commande (194) dont les petites dimensions permettent de la placer sans gene dans l"aire de travail du dentiste. L"unite de commande engendre un signal de commande du fonctionnement, un moyen detecteur isole electriquement de l"unite de commande produit en reponse au signal de l"unite un signal qui agit sur les moyens (125) d"enclenchement de la source de lumiere. Les moyens de commande peuvent comporter des moyens pour detecter la presence ou l"absence de lumiere, ou des moyens sensibles a d"autres ondes electromagnetiques.
