Patent number: 7029277Abstract: 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.Type: GrantFiled: October 17, 2002Date of Patent: April 18, 2006Assignee: Coltene / Whaledent Inc.Inventors: Igor Y. Gofman, Joseph G. Colombo

Patent number: 6945436Abstract: A dispenser for dispensing extrudable material from a cartridge. The dispenser includes a housing having a first recess for holding the cartridge, a plunger movable along the longitudinal axis of the first recess, a driver element for selectively engaging and moving the plunger in a forward direction along the longitudinal axis, and a clutch element for and selectively engaging the plunger to restrain movement of the plunger in a rearward direction. When the clutch element restrains the plunger, movement of the plunger in the rearward direction is limited to a predetermined distance.Type: GrantFiled: October 1, 2003Date of Patent: September 20, 2005Assignee: Coltene/Whaledent Inc.Inventor: Stanley Mayer

Patent number: 6900673Abstract: A micro-controller adjustably provides a scanning frequency for operating a driver for an ultrasonic device. The frequency is adjusted within a defined range until an acknowledgement signal is provided to the micro-controller to lock a currently selected frequency as the operating frequency. An indicator indicates when a frequency has been selected outside of the defined range. The device is preferably implemented as a complex programmable logic device (CPLD).Type: GrantFiled: June 4, 2002Date of Patent: May 31, 2005Assignee: Coltene/Whaledent, Inc.Inventors: Joseph G. Colombo, Igor Y. Gofman

Patent number: 6442339Abstract: A method and apparatus for curing dental material with radiation from a halogen lamp provides for a shifting of a spectrum of the radiation to a shorter wavelength for increased rate of curing by adjusting current flow within a heating element of the lamp. The current is applied over an interval of time for accomplishing the curing. Feedback and feedforward circuitry, operative with a control signal of a regulated power source to reduce voltage applied by the power source to the heating element during an initial portion of the interval of time, prior to obtaining an operating temperature of the heating element, to maintain an upper bound on the magnitude of the current applied to the heating element, thereby to the vivid unnecessary and operations of the heating element for increased operating lifetime of the lamp.Type: GrantFiled: May 4, 2001Date of Patent: August 27, 2002Assignee: Coltene/Whaledent, Inc.Inventors: Igor Y.
