Abstract: An improved framing square having integral features for automating the marking and cutting of angles. The square contains two sliding carriages—one in the body and one in the blade. Each carriage has a deployable pin. In order to set an angle, the user first deploys the pins in each sliding carriage so that they protrude downward from the square. Next, the user sets the sliding carriage in the body to the desired position and locks it in place. The user then sets the sliding carriage in the blade to the desired position and locks it in place. The two pins protruding from the sliding carriages are then butted against the board to be cut. Once they are in place, the blade of the square will form the correct cutting angle across the board. Since many common cuts employ a twelve inch base leg, the invention includes another feature: Rather than set the sliding carriage within the body to twelve inches, the user may opt instead to deploy a fixed pin located in the body at the twelve inch position.

Abstract: A gauge and a method for using the gauge, measures the Frankfurt Mandibular Angle (FMA) non-invasively, without the use of x-rays. The gauge has an upper bar that, in use, parallels the patient's porion-orbitale line. A downward bar depends from the upper bar and has an adjustably attached lower bar. The lower bar is adjusted to parallel the patient's gonion-menton line. Once the gauge is properly adjusted to the patient and locked into place, the user reads a measuring device on the gauge, which indicates the relative positions of the components of the adjusted gauge. These reading are then correlated, directly or indirectly, to the patient's FMA.
