Abstract

This patent teaches a machine for measuring angles over multiple simultaneous axes and calculating the compounded angle using tilt sensors and/or accelerometers, and including provision for establishing a baseline or zero point for each axis plus a micro-processor that receives inputs from the tilt sensors, converts them into measurements of angles, may calculate the compound angle(s) thereof, displays the results and, on demand, records the results in memory.
