  • Patent number: 4941267
    Abstract: A method and apparatus for obtaining an actual measurement in feet and inches of the distance between two points which appear on a scaled drawing by adjusting a first and second indicator to locate on the drawing a first and second point, and generating a voltage signal corresponding to the distance between the two points. A converter then converts the voltage signal to a frequency signal which is received by a first counter which generates a first binary count in response thereto. Logic gates couple the first counter to a second counter which generates a second binary count which is incremented by the first counter when the first counter reaches twelve. The first and second binary counts represent the feet and inches, respectively, portion of the measurement, and the actual measurement in feet and inches is displayed on liquid crystal displays mounted in the housing of the apparatus.
