Abstract: A method for monitoring at least one motor vehicle having a vehicle system configured to guide the motor vehicle in a completely automatic manner and a communication device configured to communicate with a remote computing device outside the motor vehicle, wherein, during the completely automatic guidance of the motor vehicle by the vehicle system an item of guidance information describing the completely automatic guidance and an item of vehicle information comprising an item of location information comprising at least a current position of the motor vehicle are transmitted to the computing device. The vehicle information received by the computing device is evaluated together with an item of driving environment information, which is available in the computing device and is based on the position of the motor vehicle, to form an item of status information relating to the motor vehicle. The item of status information and is displayed to a person carrying out the monitoring on a display device.

Abstract: The invention relates to a device (10) for taking a safety precaution in an electrical tool, said electrical tool comprising an electric motor (EM) with at least one field winding and an armature winding. The device (10) comprises the following features: a sensor unit (12) which is designed to generate a sensor signal (21) in accordance with a motor current (14) passing through the electric motor (EM), an armature voltage (16) via the armature winding, a voltage (18) via the field winding and/or a commutation frequency (20) in the armature winding; a unit (22) detecting a change of the sensor signal, which is designed to detect a temporal change of the sensor signal (21) and emit a corresponding modification signal (24) on the basis of the detected change; and a safety device (26) which is designed to take a safety precaution (28) in the electrical tool when a value of the modification signal (24) is exceeded or not met in relation to a threshold value.
