US Patent 11692820 Digital level

A tool, such as a digital level, having multiple methods of indicating the orientation of the level. One embodiment of the level includes two or more accelerometers arranged in complimenting orientations, such as 90 degrees with respect to each other. The complimenting orientation allows for more precise measurements from less expensive accelerometers compared to a level with a single more expensive accelerometer. A power supply module, and an associated control module in charge of the power supply, selectively provides power to the accelerometers and displays based in part on user input, movement of the level, and the disposition of the level.
