    摘要: A water control valve includes a valve body defining a valve body internal cavity, a first air inlet passageway in communication with the valve body internal cavity, a first water outlet passageway in communication with the valve body internal cavity, and a water inlet passageway. The water control valve further includes a valve cartridge removably coupled to the valve body. The valve cartridge is sized to fit at least partially within the valve body internal cavity. The valve cartridge defines a second air inlet passageway and a second water outlet passageway. The first air inlet passageway is aligned with the second air inlet passageway and the first water outlet passageway is aligned with the second water outlet passageway when the valve cartridge is coupled to the valve body.

    摘要: A headrest adjustment system includes a tension block having a threaded aperture extending entirely through the tension block. The tension block is configured to be coupled to a chair. The headrest adjustment system also includes a screw configured to be moved through the threaded aperture along an axis, and a clamp lever pivotally coupled to the tension block. The clamp lever has an inclined surface. The axis intersects the inclined surface at an oblique angle. The headrest adjustment system also includes a headrest tension bracket configured to be coupled to the chair. The headrest tension bracket has a first end and a second end and the second end includes a flange. The clamp lever is configured to contact and press against the flange upon movement of the screw.

    摘要: An electrically powered light source including a light emitting diode (LED) having variable chromaticity, which is adapted for use in a dental operatory. A dental operatory lamp includes a thermally conductive housing having a front directed toward the operating area and a rear away from the operating area; a generally elliptical reflector located on the rear of the thermally conductive housing; at least one heat pipe; a plurality of color LEDs projecting light toward the elliptical reflector, the plurality of LEDs being in thermal contact with the at least one heat pipe; and an optical light guide for combining light from said LEDs. Another embodiment of the lamp includes at least two user selectable light spectra, one of said spectra providing white light with color temperature in the range 4000° K-6000° K and one spectra having reduced output in the wavelength range 400-500 nm.

    摘要: A predictive maintenance system and method for a dental handpiece includes a condition sensor for sensing a condition of the handpiece to obtain sensor data and providing wired communication of the sensor data and a device identifier from the handpiece to a delivery unit. The system is configured to store sensor data, a device identifier and a time stamp in data logging equipment to obtain a usage history for the handpiece. The system determines a maintenance condition of the handpiece based on the sensor data and/or the usage history of the handpiece. In response to a severity of the maintenance condition, the system provides a preventative maintenance indication of a future failure for the handpiece or stops operation of the handpiece.
