  • Tooth stability monitor
    Patent number: 4881552
    Abstract: A tooth stability monitor for assessing the rigidity of a tooth. A tooth probe 11 is provided for sinusoidally moving the tooth at a constant small amplitude. A displacement sensor 13 measures the resulting displacement of the tooth and a force sensor 14 measures the resulting force applied to the tooth. Feedback electronics 15 receives the two measurements and calculates the tooth modulus.

  • Flow monitor of liquid drops
    Patent number: 4869722
    Abstract: A device for accurately monitoring the flow and flow rate of liquids that are released slowly so as to form drops. The drops fall from the tip of a drop funnel 13 onto a surface of liquid at the top of a reaction cell 16. Consequently, the height through which each drop falls is constant. The liquid volume of each drop is measured and the flow and flow rate are calculated by transducer 19 and flow meter processing electronics 22.
