US Patent 12111150 Framing square

The framing square may comprise a square, a carrier, and a laser distance meter. The framing square may be a tool for measuring a right angle. The square may be a metal armature comprising two arms that form the right angle. The carrier may slide in a carrier located on a first arm. The laser distance meter may be coupled to the carrier and may optically measure a separation distance between the first arm and a first object. A second arm may be placed adjacent to a second object. Two separation distance measurements from different positions on the first arm may determine if the first object is perpendicular to the second object, even when the first arm is not in contact with the first object.
