    摘要: The present invention is directed to a method for shutting off a drive motor (12) of a power tool that drives a tool, the drive motor (12) being shut off as a function of a variable threshold value (E1) if the tool jams. It is provided that the threshold value (E1) is determined in at least one predetermined time interval (T1) as a function of a current load speed (n1) and a no-load speed (n0).

    摘要: A sensor arrangement for ascertaining the density and the viscosity of a liquid is proposed, having an arrangement comprising at least two basic sensor elements, at least one of which can be wetted with the liquid, and having electro-acoustical transducers (6) in the basic sensor elements for generating and detecting surface acoustic waves with predetermined wave modes, from whose propagation behavior along a measurement path a measure for the density and the viscosity of the liquid can be ascertained. Liquid traps (17) for the liquid, which extend in the applicable measurement path, are disposed in the region of at least one of the basic sensor elements, parallel to the direction of propagation of the surface acoustic wave.

    摘要: The present invention is based on a method for operating a guided power tool (10), in particular an electric power tool, with a rotatably and/or percussively driven insert tool (36), whereby the insert tool (36) is driven into a work piece (34) in a work process. It is proposed that at least one measured signal detected at the power tool (10) during the work process is evaluated to derive a property of the work piece (34) located in the working direction of the Insert tool (36), and the power tool (10) is operated in accordance with the property. A guided power tool is also proposed.
