    Abstract: A dental instrument system has an optical component with a mirror for the dental practitioner to view a patient's mouth. A light source and an airflow source have a plurality of output levels that are controlled by a user input on the handle, such as a single button. The output levels of the light and airflow are controlled by a single or double click, wherein a single click increases the output level of the airflow and a double click increases the output level of the light, for example. The light source illuminates the mirror and the airflow source produces airflow over the mirror to remove debris and bodily fluid. A clearing flow of air may be initiated by holding the single button down on the handle and release of the button may return the airflow to the previous level.

  • Patent number: 9908158
    Abstract: This invention provides a mechanism for clearing debris and vapors from the region around the optical axis of a vision system that employs a directed airflow in the region. The airflow is guided by an air knife that surrounds a viewing gap placed in front of the camera optics. The air knife delivers airflow in a manner that takes advantage of the Coanda effect to generate an airflow that prevents infiltration of debris and contaminants into the optical path. Illustratively, the air knife defines a geometry that effectively multiplies the delivered airflow approximately fifty times (twenty-five times on each of two air-knife sides) that of the supplied compressed air. This provides an extremely strong air curtain along the scan direction that essentially blocks infiltration of environmental contamination to the optics of the camera.

  • Patent number: 8596798
    Abstract: An access probe for remote-sensing access through a viewing port, viewing volume, and access port into a vessel. The physical boundary around the viewing volume is partially formed by a porous sleeve lying between the viewing volume and a fluid conduit. In a first mode of operation, a fluid supplied to the fluid conduit encounters the porous sleeve and flows through the porous material to maintain the viewing volume free of ash or other matter. When additional fluid force is needed to clear the viewing volume, the pressure of the fluid flow is increased sufficiently to slidably translate the porous sleeve, greatly increasing flow into the viewing volume. The porous sleeve is returned to position by an actuating spring. The access probe thereby provides for alternate modes of operation based on the pressure of an actuating fluid.

  • Patent number: 8497466
    Abstract: An apparatus for checking mechanical component parts, such as tools in machine tools, uses optical devices for emitting and receiving a light beam, for example a laser beam, and sensors for detecting the interruption of such light beam. A protection device for at least one of the optical devices includes pneumatic conduits and a nozzle outputting an air stream from a plurality of holes located around the central conduit through which the light beam passes, so generating a tubular shield which embraces the light beam. The protection device further includes a shutter which can be displaced from a rest position, wherein the central conduit is closed and the inside of the protection device is pressurized, to a working position, wherein the nozzle delivers the air stream in the form of a tubular shield. Passing from the rest position to the working position, the shutter assumes an intermediate transit position in which an air blast is outputted through the central conduit for a short time interval.

  • Patent number: 8425058
    Abstract: A lens unit or the like with improved ability to capture proper images by reducing the likelihood that water droplets will adhere to the lens surface and change the refractive index. A surface of a lens portion (1) is imparted with a water-repellent property and a surface of a non-lens portion (2), surrounding the lens portion (1), is imparted with a hydrophilic property. As a result, if droplets on the surface of the lens portion (1) contact the non-lens portion (2), the droplets are guided from the water-repellent surface of the lens portion (1) to the hydrophilic surface of the non-lens portion (2) thereby reducing the number of droplets residing on the lens portion (1).
