An apparatus for detecting the position of window handles or door handles, the apparatus including a magnetic-field sensor and a microcontroller unit, the microcontroller unit being designed to read out data from the magnetic-field sensor, to record a magnetic fingerprint for at least one window-handle/door-handle position, and to detect the at least one window-handle/door-handle position by comparing data of the magnetic-field sensor with the recorded magnetic fingerprint. An operating method for such a window handle or door handle is also described.

The disclosure relates to a method for balancing out states of charge of a battery which has a number of N battery cells. In order to balance out the individual states of charge (SOCn) of the n=1 to N cells, the state of charge of at least one cell is changed to a target state of charge (SOCtarget,n) which depends on the discharge depth (DODk) of the cell having the lowest capacity (Capk) according to the equation SOCtarget,n=1&#x2212;DODk/Capn, Capn being the capacity of the nth cell to be changed. Advantageously, the method is suitable for optimizing the voltage or the energy content of a battery that is constituted of a plurality of cells.

A method for ascertaining a closing state of a house door or of a house window, having the following method steps: acquisition of a rate of rotation of the house door or of the house window using a first acquisition device, and calculation of an opening angle of the house door or of the house window on the basis of the acquired rate of rotation, and ascertaining whether the calculated opening angle falls below a prespecified angular threshold value; acquisition of a rate of vibration of the house door or of the house window using a second acquisition device, and ascertaining whether the acquired rate of vibration exceeds a prespecified rate of vibration threshold value within a prespecified first time span; and ascertaining whether the acquired rate of rotation exceeds a prespecified rate of rotation threshold value within a prespecified second time span since the exceeding of the vibration rate threshold value.

A method for determining the unauthorized intrusion through a door, including: a) determining a movement path of the door as a function of time in all three spatial axes using a movement sensor in an active mode; b) determining parameters in all three spatial axes based on the movement path of the door, an unauthorized intrusion at the door exists when the actual value of the particular parameter is within an assigned parameter range for the unauthorized intrusion; c) determining an opening angle of the door using an angle measuring sensor when an unauthorized intrusion has been determined; and d) comparing the opening angle of the door with a threshold value for a closed door; e) determining that the door has been opened when the opening angle exceeds the threshold value, and outputting an alarm signal if the door has been opened. A device is also described.

An intrusion sensor for monitoring an entrance to a building to be monitored, the intrusion sensor being situated at the entrance on the inside of the building, includes an acceleration sensor which is configured to detect motions of the intrusion sensor in at least one spatial axis, and in the case of a motion in the at least one axis, to output an acceleration signal, including a surroundings sensor which is configured to detect at least one value of at least one physical variable in the surroundings of the intrusion sensor, and including a plausibility check device, which is configured to carry out a plausibility check of the acceleration signal using the detected value of the physical variable, and to output an intrusion signal if the result of the plausibility check is negative. Also described is a corresponding method and an alarm system including an intrusion sensor.

A sensor system for a locking system of a door includes: an acceleration sensor which is designed to detect movements of the door in at least two dimensions and to record a time-resolved acceleration profile; a magnetic field sensor which is designed to detect a magnetic field in the area of the locking system, to detect changes of the magnetic field and to record a time-resolved magnetic field change profile; and a control device which is coupled to the acceleration sensor and to the magnetic field sensor and which is designed to correlate the acceleration profile to the magnetic field change profile, to compare the profile correlation to a predetermined correlation signature, and to output an alarm signal if the profile correlation matches the correlation signature.

The present disclosure relates to a method and an arrangement for monitoring at least one battery, to a battery having such an arrangement, and to a motor vehicle having a corresponding battery that is used for safely monitoring the battery condition with a reduced amount of hardware. The at least one battery is monitored by analyzing measured variables of the at least one battery using at least one data processing device. The signals exchanged between the at least one battery and the at least one data processing device via a communication connection are monitored at least once.

In a method for measuring lift and for adjusting a valve, easily focused, high-energy radiation is used, which permits a contact-free measuring operation. The radiation is directed at the valve-closure member that is permanently joined to the valve needle in the installed valve. By performing a differential measurement, thus a measurement in both end positions of the valve needle, the lift of the valve needle can be determined and, thus, corrected. The measurement is performed on a dry valve. The method is particularly suited for electromagnetically actuated fuel-injection valves of mixture-compressing internal-combustion engines having externally supplied ignition.
