Oct 17, 2002

Appl. No.:

10/273394

Inventors:

Igor Y. Gofman - Croton-on-Hudson NY, US
Joseph G. Colombo - Hackensack NJ, US

Assignee:

Coltene / Whaledent Inc. - Cuyahoga Falls OH

International Classification:

A61C 1/00

US Classification:

433 29

Abstract:

A light for a curing instrument includes a plurality of light sources, each producing an incident light beam. The incident light beams are combined to produce a single output beam, which exhibits a broader spectral width than any of the incident light beams. In one embodiment of the invention, the output beam exhibits an intensity over a spectral range defined by a first characteristic wavelength of a first of the plurality of light sources and a second characteristic wavelength of a second of the plurality of lights sources such that the intensity varies by no more than 25 percent over the range. In another embodiment of the invention including a one or more blue LED light sources among the plurality of light sources, at least one white LED is included in the plurality of light sources in order to generate an output light beam having a component portion that is characterized as green. In a third embodiment of the invention, a plurality of fiber optic bundles receive the incident light beams, and are arranged at a transmitting end so that individual fibers from the plurality of bundles are randomly combined to form a single output surface for transmitting the output beam.

International Classification:

G10L 13/02

US Classification:

704274

Abstract:

A curing lamp apparatus is used for providing electronic voice information to report a number of operating conditions associated with the curing lamp. The apparatus includes a light sensor for sensing output power, voltage and current sensors for sensing input power, a microcontroller for providing a digital number in response to receiving signals from one or more sensors, a programmed voice circuit for retrieving a voice message signal from a memory, address associated with the digital number, and a transducer for receiving and audibly reproducing the voice message signal.

B65D 69/00

US Classification:

12820326, 206570, 12820413

Abstract:

The present application relates to a liquid-evaporate delivery device which relies on the efficient use of air currents to deliver liquid evaporate to airspace around the device. Efficient air currents may be provided by rotating the air currents around the wick, by providing a helical channel for the air to flow around the wick, and/or by aligning a fan with the longitudinal axis of the wick.
