Paragraph Number

120

As with the input circuit 310 and output circuit 320, those of skill in the art appreciate that the measurement circuit 330 and/or calibration circuit 340 can have different configurations in different embodiments. The measurement circuit 330 measures a change in orientation angle of a shaft 210 in relation to a reference axis. In certain embodiments, the measurement circuit 330 measures the orientation angle of the shaft 210 relative to the reference axis in response to input data from a user (e.g., pressing or activating a button or switch). Alternatively, or in addition, the measurement circuit 330 measures the orientation angle of the shaft 210 relative to the reference axis in real time (e.g., as a user tilts the shaft 210 toa desired orientation) and coordinates with the control circuit 350 to update the orientation angle communicated to a user (e.g., displayed on a display), almost instantaneously.
