    Abstract: The present disclosure discloses a device for determining orientation of an object. The device comprises a hollow spherical member. A plurality of sensors are positioned within a cavity defined by an inner surface and an outer surface of the hollow spherical member. Further, the device comprises a light source fixed within the hollow spherical member, and a solid sphere provided within the hollow spherical member. The solid spherical member is configured to displace within the hollow spherical member, pointing towards gravity and occupies lowermost position of the hollow spherical member, and thus blocks impingement of light on to corresponding one or more sensors at the lowermost position of the hollow spherical member. The blocked one or more sensors activate or deactivate, and generate a signal, which is received by a computing unit, to determine orientation of the object.

    Abstract: A tool, such as a digital level, includes displays on top and side surfaces of the level. The top surface display provides an additional visual means to communicate the orientation of the level by emitting any of several visual signals. A processor in the level determines a measured orientation of the level and sends a communication signal to the top surface display to emit a selected visual signal based on the measured orientation.

    Abstract: 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.

    Abstract: Inclinometers with a parallel dipole line (PDL) trap system are provided. In one aspect, an inclinometer includes: a PDL trap having a pair of dipole line magnets, a transparent tube in between the dipole line magnets, and a diamagnetic object within the transparent tube, wherein the diamagnetic object is levitating in between the dipole line magnets; and a sensing system for determining a position z of the diamagnetic object in the PDL trap and for determining an inclination angle θ using the position z of the diamagnetic object in the PDL trap. Techniques to detect the diamagnetic object position using optical, capacitive and manual methods are described. A method for determining an inclination angle θ using the present inclinometers is also provided.
