Patents by Inventor Martin Sachsenmaier

Martin Sachsenmaier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Universal non-electronic multi-sectional gradient meter and inclinometer and method of use
    Patent number: 6691421
    Abstract: A novel apparatus and method for use in measuring surface slope is disclosed. In a preferred embodiment, the measurement apparatus includes a fluid case having an arch of flat segments forming a sloped ceiling. In another preferred embodiment, a smooth curve, instead of a series of flat segments, is formed by reducing the length, and increasing the number, of the constant slope flat segments. And in a preferred embodiment, the apparatus provides a mechanism for compensating for any expansion or contraction of the fluid in the fluid case. A method for measuring the slope of a surface includes providing a measurement apparatus, placing the measurement apparatus adjacent the surface and reading an indicator corresponding to the slope of the surface.
