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.

Abstract: A device and a method for determining states of an object to be monitored, such as a window or a door. The measurement values of a plurality of sensors, in particular a magnetometer and an acceleration sensor, are merged and are evaluated together. For the determination of a new state from a group of predefined states, only state transitions that are actually possible are taken into account. State transitions that are not possible or are not allowed are not taken into account.

Abstract: A method for calibrating a structure-borne sound-sensitive acceleration sensor with the aid of at least one microphone. For this purpose, the acceleration sensor is situated in an intended position on the body of a user. Furthermore, at least one acceleration sensor signal and at least one microphone signal are detected, the at least one acceleration sensor signal and the at least one microphone signal being synchronized and having been caused by a vocalization of the user. A frequency analysis of the acceleration sensor signal and a frequency analysis of the microphone signal are carried out. A frequency-dependent correction function for correcting the transmission function of the acceleration sensor is ascertained on the basis of the frequency analyses of the acceleration sensor signal and the microphone signal.

Abstract: A device and a method for detecting a state of an electrical device. A magnetic field is thereby measured by a magnetic field sensor along an electrical power supply cable of the electrical device via which the electrical device is supplied with power; a magnetic field is thereby measured by a magnetic field sensor, and the magnetic field measured in this manner is compared with previously determined reference values in order to determine the operating state of the electrical device. The process of determining the reference values may thereby be individually adapted in an upstream calibration process to the electrical device to be monitored.

Abstract: An earphone including a proximity sensor, an acceleration sensor, and a signal analysis device. The signal analysis device identifies an approaching movement of the earphone to an object using the proximity sensor signal. The signal analysis device ascertains whether the approaching movement is a movement of the earphone to an ear of the user. By filtering the acceleration sensor signal, the signal analysis device generates a high-pass filtered acceleration signal and a low-pass filtered acceleration signal. The signal analysis device determines an end time of the approaching movement based on a stabilization of the acceleration, using the low-pass filtered acceleration signal. The signal analysis device confirms that the approaching movement is a movement of the earphone to an ear of the user based on changes in the high-pass filtered acceleration signal after the ascertained end time of the approaching movement.

Abstract: An inertial sensor unit, including a sensor element for detecting and converting movements and vibrations into an electrical sensor signal, a signal processing element for evaluating the sensor signal, and an interface for signaling a detected speech activity. The signal processing element includes a first processing stage which checks a first criterion for the presence of a speech activity, and a second processing stage which checks a second criterion for the presence of a speech activity, the second processing stage being passed through only if the sensor signal has passed through the first processing stage and the first criterion for the presence of a speech activity has been met. The signal processing element is designed to activate the interface for signaling a speech activity only if the sensor signal has passed through the second processing stage, and the second criterion for the presence of a speech activity has been met.

Abstract: The detection of a use status of an object. To ascertain the use status, i.e., the decision as to whether or not an object is presently in use, using sensor data of multiple sensors provided at the object. For this purpose, in particular, the individual results about the use status may be correlated with one another. When needed, additional sensors may be activated and incorporated in the evaluation.
