Abstract
An electronic alignment system is disclosed. The system has at least two accelerometers, mounted in the device in such a manner that the accelerometers are mutually perpendicular to one another. An electrical connection electrically connects the accelerometers, a computing and processing device, a memory device, a feedback device, and a power source. A three axis reference frame is used as a basis for determining the angle of rotation of the device about an axis. Two accelerometers are required to determine a first angle of rotation. Adding a third accelerometer allows for the calculation of a second angle of rotation. Distance sensors can determine distance to a work piece, how far the device has traveled relative to a work piece, areas and volumes, and a third angle of rotation. Gyroscopes can also determine a third angle of rotation. The device may also include light projectors.
