  • Publication number: 20160238365
    Abstract: A digital protractor is provided for measuring spring and wall angles and determining and effecting bevel and miter angle adjustments of a miter saw to adjoining pieces of trim in accordance with the measured spring and wall angles. The protractor includes a pair of pivotally interconnected arms. At least one sensor is attached to one of the arms and a digital readout is secured to the other arm. The readout includes means for determining the bevel and miter angles such that the protractor can be set to those angles to properly adjust the miter saw in accordance with the calculated angles.

  • Publication number: 20140237837
    Abstract: A digital angle gauge includes a gauge body having a reference surface that is engageable with an object to be measured for angular inclination. An angle sensor and processor mounted in the body determine an inclination angle of the object with which the reference surface of the gauge body is engaged. A digital screen is pivotally mounted to the gauge body for visually displaying the determined inclination in both incremental and absolute angles that are displayed simultaneously and side by side.
