  • Patent number: 9873189
    Abstract: The invention relates to a method for operating a hand-held working device (1), which comprises a data acquisition unit (24) in which actuations of the trigger switch and accelerations of the working device (1) are captured. In order to further simplify and/or improve the operation of the hand-held working device, it is monitored within a limited period of time after actuation of the trigger switch whether an acceleration of the working device (1) exceeds an acceleration threshold in order to detect trouble-free ignitions and/or ignition problems during the operation of the working device (1).

  • Patent number: 8412179
    Abstract: A method of configuring power tool electronics in a hand-held power tool (10) having sensor means (20) for acquiring measurement data, a control unit (50) for processing measurement data and for controlling power tool functions, and a data transmission unit (30), includes transmitting data between the data transmission unit (30) and an evaluation location (62) by means of a mobile wireless network, with the power tool electronics being awakened from a quiescent mode (70) and activated at a time stored as a time parameter in a control program, retrieving a configuration file provided by the evaluation location (62) by the data transmission unit (30) via the mobile wireless network, and checking the response received from the mobile wireless network to determine whether or not it contains a new configuration file. If a configuration file was received, the parameters contained in the configuration file are implemented (77) in the control program for the power tool electronics.
