    Abstract: A two-wire reference accelerometer includes integrated mechanical transducing and self-calibration capability based on gravity only. The reference accelerometer includes an external two-wire connector and an internal three-wire transducer that responds to both steady-state acceleration and time-varying accelerations by producing a modulated transducer output signal having a steady-state waveform when the transducer senses steady state acceleration and a time-varying waveform when the transducer senses time-varying accelerations. A signal conditioning circuit conditions the transducer output signal and applies it to the two-wire electrical connector as a modulated reference accelerometer output signal. The transducer and the signal conditioning circuit can operate without modification in either a DUT calibration mode or a self-calibration mode. The self-calibration mode determines the 1 g output sensitivity of the reference accelerometer from first and second readings of the reference accelerometer output signal taken while the reference accelerometer rests on a non-accelerating surface in respective non-inverted and inverted orientations.

    Abstract: The invention relates to a detector arrangement and method for determining a mutual position or a mutual state of motion of at least two structural parts of a mobile work machine. The arrangement comprises detectors configurable to determine at least in one direction of measurement at least two different measured variables in order to determine at least structural-part-specific position or state of motion information for each direction of measurement. The arrangement further comprises a data processing means for receiving measurement signals describing measured variables as well as for determining a mutual position or state of motion of the structural parts on the basis of the structural-part-specific position or state of motion information.

    Abstract: A method and a device for determining an angle of rotation of an object about a rotation axis. The method includes measuring a first acceleration profile of an acceleration sensor mounted on the object during a first period of time; and computing the angle of rotation by which the object has rotated about the rotation axis during the first period of time, based on the first accelerations during the first period of time and based on a predetermined distance of the acceleration sensor from the rotation axis. The device includes an acceleration sensor which is mountable on the object; and a computing device which is designed for determining the angle of rotation based on an acceleration profile measured by the acceleration sensor during a period of time, and based on a predetermined distance of the acceleration sensor from the rotation axis.
