  • Publication number: 20200323477
    Abstract: A balance testing apparatus for testing balance of a test subject having a stance foot and an excursion foot includes a mat, at least one elongate reference line and an electronic measuring device. The mat has a stance foot orientation guide for receiving the stance foot. The at least one elongate reference line extends radially from the stance foot orientation guide. The electronic measuring device is designed for measuring the distance between the stance foot and the excursion foot when the excursion foot is on or near the reference line. A method of balance testing using the balance testing apparatus includes the steps of: measuring a first predetermined parameter having the stance foot in a first predetermined position; storing the data; repeating the steps with the stance foot in a different predetermined position; and evaluating the data to obtain a balance test protocol score.

  • Patent number: 6963443
    Abstract: The present invention relates to an optical parametric oscillator including a non-linear optical crystal and two glass substrates surface contacted to the opposite ends of said crystal. The substrates include mirrors on their outer surfaces so that the combination of the mirrors, substrates and the crystal functions as the parametric oscillator. The invention also relates to the method of producing such an oscillator that overcomes the problems of surface contact bonding and laser damage threshold by use of an alkaline polishing compounds on the crystal ends.
