  • Patent number: 10597125
    Abstract: A height adjustable depth finder system is provided such that a user may easily raise and lower the height at which a depth finder display is located. Height adjustability may be provided by one or more supports, with at least one support actively driven. The one or more supports may telescope to provide height adjustability and are actively driven by an actuator that may include a wire feed motor or a rack and pinion. In the event of two supports, the two supports may be perpendicular (side-by-side) or parallel (front and back) with the longitudinal axis of the boat. The longitudinal axis of the boat generally forms a “V” line at the lowest part of the hull running from the bow to the stern of the boat.

  • Patent number: 9610137
    Abstract: A dental work site illumination system provides illumination directly onto a work site under professional dental care. The illumination emanates from a light source within the swivel coupling, the light source being energized by an electrical generator mounted within the coupling. The generator is driven by a turbine wheel that is caused to rotate by a flow of exhaust fluid, i.e. compressed fluid after having driven a dental tool. The light source transmits illumination to a fiber optic bundle that terminates adjacent to the dental work site.

  • Patent number: 8777614
    Abstract: A detection system for remotely determining the speed of a rotating tool tip in a pneumatic dental handpiece. A means for detecting the speed of the rotating tool tip monitors a periodic mechanical function at the pneumatic hose connected to the handpiece. The monitored periodic mechanical function serves to provide feedback that is used to control the speed of the rotating tool tip. The means for detecting the speed of the rotating tool detects a mechanical function of the rotating tool tip, which in transmitted to a controller. The controller in turn regulates the operation of an air supply valve in response to the detected mechanical function. The valve regulates the flow of air to the handpiece. By continuously adjusting the flow of air through the valve into the pneumatic hose, the speed of the rotating tool is maintained at the desired cutting speed.

  • Patent number: 6607385
    Abstract: In a method for controlling a torque of a motor of dental and surgical handpieces to not exceed a set-point value when screwing in implant members, a motor current for applying the set-point torque is determined immediately before screwing in an implant member with the handpiece and the motor current is limited to the set point value with a motor control during subsequent screwing in of the implant member. The device for carrying out the method has a torque limiter, connectable to a tool receptacle of a handpiece, and a motor current measuring device for measuring a motor current of the motor of the handpiece.

  • Patent number: 6506050
    Abstract: In order to control a dental device having at least one treatment instrument (1), a central control device and a display unit (2), the device has additional means (4, 5, 6) for detecting the spatial position of the treatment instrument (1). In a control mode, the detected spatial position of the treatment instrument (1) is converted by the control device into coordinates for controlling and operating a pointer (3) on the display unit (2). The treatment instrument (1) is thus also used as an input instrument, its method of functioning being similar to that of a computer mouse.

  • Patent number: 6419487
    Abstract: An exhaust manifold for a dental handpiece system receives at an inlet thereof return air flow provided by a dental handpiece. A unidirectional valve couples the inlet to a common manifold space which in turn couples to ambient air by way of a filter. By applying filtration on the backside of the unidirectional valve, air entering the common manifold space cannot thereafter reenter the return air conduit and thereby contaminate the same handpiece or other handpieces in a multiple handpiece system. A replaceable filter unit avoids accumulated debris and promotes better sanitary conditions.

  • Patent number: 6019905
    Abstract: A method for providing an active sanitized aqueous medium in a dental treatment operation. A chlorinated water supply is treated with a physiologically-safe acidifier to provide a substantially enhanced hypochlorous acid concentration. The water is treated to convert the hypochlorite ion into the much more bacteriocidal undisassociated hypochlorous acid. A reservoir is provided at a suitable location, such as a dental treatment station. Potable water from a suitable source is supplied to the reservoir. The potable water contains free chlorine in an amount of at least 0.1 ppm. The water in the reservoir is treated with a physiologically-safe acidifier selected from the group consisting of inorganic acids, organic acids, and acid esters which have GRAS status.
