Abstract: A method, including: obtaining first acceleration data output by an angle sensor at each first test angle and corresponding second acceleration data which is nominal data in case where the angle sensor rotates about a first axis; obtaining third acceleration data output by the angle sensor at each second test angle and corresponding fourth acceleration data which is nominal data in case where the angle sensor rotates about a second axis in a situation that a turntable mechanical platform rotates 90 degrees about a third axis; constructing a calibration data model between output acceleration data and calibrated acceleration data, based on the first, second, third, and fourth acceleration data; determining calibrated acceleration data corresponding to acceleration data output at any angle based on the calibration data model; and obtaining a calibrated angle of the angle sensor at any angle based on the calibrated acceleration data of that angle.

Abstract: The vibration damping device comprises a first vibration damping unit. The first vibration damping unit comprises protective nets, a fixing plate, a base, a guide element, a first elastic element and a limiting element. The fixing plate is arranged opposite to the base and connected to the protective nets. The guide element is located between the fixing plate and the base and opposite to the base. A movement space is formed between the guide element and the base. The base is also configured to be connected to a cab body. The first elastic element is arranged in the movement space. The limiting element has one end connected to the base and the other end working together with the fixing plate to limit the stroke of the first elastic element.

Abstract: This disclosure relates to an inertial sensor, and to the field of embedded designs. The inertial sensor includes at least one inertial measurement unit; a controller configured to read measurement data of the at least one inertial measurement unit, wherein the at least one inertial measurement unit is couplable to or decouplable from the controller; and a plurality of sets of interfaces, wherein each set of interfaces has a first end electrically connected with the controller and a second end electrically connected with one of the at least one inertial measurement unit.
