A device for ascertaining the orientation of a drill relative to a plane, the device being capable of being connected to the drill, the device having a laser distance measuring unit by which, from a prespecified position relative to the plane, a first distance to a first point in the plane and a second distance to a second point in the plane can be measured, and having an evaluation unit that is configured such that on the basis of the first distance and the second distance the orientation of the device relative to the plane can be ascertained.

A method for generating a signal representing an impact intensity including the steps: receiving at least three signals, which represent respectively accelerations in different spatial directions; calculating a direction-independent variable from the three signals; ascertaining an integrated measurand of the direction-independent variable over a time window; generating a signal representing an impact intensity on the basis of the ascertained integrated measurand.

An angle grinder includes a housing, a drive unit configured to drive a usage tool, a sensor device configured to provide a rotation parameter, and a control unit configured to evaluate the rotation parameter to detect a clamped state of the usage tool. The sensor device has a yaw rate sensor configured to provide the rotation parameter in accordance with a rotational movement of the housing. The control unit triggers a safety mode in accordance with the rotation parameter or throttles the rotational speed and/or torque of the drive unit.

A method for determining the sensitivity of a sensor provides the following steps: a) first and second deflection voltages are applied to first and second electrode systems of the sensor, respectively, and first and second electrostatic forces are exerted on an elastically suspended seismic mass of the sensor by the first and second electrode systems, respectively, and a restoring force is exerted on the mass as a result of the elasticity of the mass, and a force equilibrium is established among the first and second electrostatic forces and the restoring force, and the mass assumes a deflection position characteristic of the force equilibrium, and an output signal characteristic of the force equilibrium and of the deflection position is measured; and b) the sensitivity of the sensor is computed on the basis of the first and second deflection voltages.
