  • Patent number: 11668690
    Abstract: A safety application mobile measuring device (100) includes a control unit (110) and a detection unit (120). The control unit controls changes between a switched-on state and a switched-off state depending on a received detection signal (112). The detection unit monitors, in the switched-off state, whether a switch-on condition (414) is present and outputs the detection signal, which indicates a change into the switched-on state which is to be carried out. The detection unit monitors the switched-on state as to whether at least two switch-off conditions (444, 448) are present and outputs the detection signal, which indicates a change into the switched-off state, which is to be carried out, in the presence of at least two switch-off conditions. At least two detection devices (122, 124) each carry out a detection corresponding to the at least one switch-on condition and to the at least two switch-off conditions.
