Abstract: An induction charging device and a method for inductively transmitting energy to an induction rechargeable battery device, with at least one primary oscillating circuit that includes at least one charging coil, and with a control/regulation unit for controlling the primary oscillating circuit with an inverter circuit. An excitation frequency of an output signal of the inverter circuit made up of half-waves essentially corresponds to a resonant frequency of the primary oscillating circuit. The induction charging device provides that, for reducing a charging current, the control/regulation unit, after an end-of-charge voltage of the induction rechargeable battery device is reached, controls the inverter circuit so that the output signal periodically sets at least one first half-wave to a high value, and an odd plurality of successive half-waves is then immediately set to a value that is low compared to the high value.

Abstract: The disclosure is based on a sensor device, in particular a hand-held power-tool sensor device, for identifying an uncontrolled occurrence of jamming in the case of a hand-held power tool, having at least one sensor unit, which is provided to sense at least one motion characteristic value of the hand-held power tool, and having a protective unit, which is provided to control the hand-held power tool in dependence on at least one triggering threshold value and the at least one motion characteristic value. It is proposed that the protective unit be provided to set the at least one triggering threshold value in a variable manner and/or to define at least one further triggering threshold value.
