摘要： Method for detecting a first operating state of a handheld power tool, wherein the handheld power tool has an electric motor. In this case, the method comprises the steps of: (S1) determining a signal of an operating variable of the electric motor; (S2) comparing the signal of the operating variable with at least one model signal waveform typical of the state, wherein the model signal waveform typical of the state is assigned to the first operating state; (S3) deciding whether the first operating state is present, wherein the decision at least partially depends on whether the model signal waveform typical of the state is identified in the signal of the operating variable in step S2. Additionally disclosed is a handheld power tool, particularly an impact driver, with an electric motor and a control unit, wherein the control unit is designed to execute a method according to the disclosure.

摘要： A positioning device for capacitively detecting an object enclosed in a medium includes a measuring electrode, a receiving electrode, and a reference capacitance. The measuring electrode and the receiving electrode form a measuring capacitance that can be influenced by the object and the reference capacitance cannot be influenced by the object. The electrodes are disposed in a plane, and the device includes a spacer that is configured to keep the electrodes at a predetermined minimum distance from the surface of the medium. The predetermined minimum distance is different from zero.

摘要： A sensor for locating metal or magnetic objects includes a first and a second transmitting coil and one receiving coil. The receiving coil includes a first and a second receiving sub-coil. The first transmitting coil and the first receiving sub-coil are arranged in a first plane. The second transmitting coil and the second receiving sub-coil are arranged in a second plane. The first transmitting coil and the first receiving sub-coil are offset in relation to the second transmitting coil and the second receiving sub-coil with respect to a common center axis which passes vertically through the planes. The first receiving sub-coil is configured differently than the second receiving sub-coil.

摘要： A circuit having a first, second, and third capacitor. Capacitor plates of the capacitors are connected to a first circuit node. The circuit supplies a first time-dependent voltage to the first capacitor, a second time-dependent voltage to the second capacitor, and a third time-dependent voltage to the third capacitor. The first and second voltages are clocked in antiphase. The second and third voltages are clocked in phase. The circuit has an amplifier, a synchronous demodulator, and a comparator. Inputs of the amplifier are connected to the first circuit node and ground. The synchronous demodulator alternately applies an output signal of the amplifier to inputs of the comparator, synchronously with the clock frequency of the first voltage. The circuit generates a control value dependent on an output of the comparator. The circuit changes amplitudes of the first and third voltage and/or the second voltage dependent on the control value.

摘要： A locating appliance configured to sense an article includes a push-pull measurement bridge and a comparator. The push-pull measurement bridge is configured to actuate a first electromagnetic device and a second electromagnetic device, in each case in a variable ratio. The first electromagnetic device takes the actuation as a basis for producing an electromagnetic alternating field in a region of the article. The comparator is configured to sense the article if the variable ratio differs from a predetermined ratio by more than a predetermined amount.

摘要： A sensor for locating metallic or magnetizable objects comprises two emission coils and a receiving coil which are inductively interconnected. A method for determining the influence of temperature on the sensor includes supplying a first pair of predetermined alternating currents to the emitter coils, and simultaneously sampling current flows which pass through the emitter coils and a first current of the receiver coil. Subsequently, the method includes supplying a second pair of predetermined alternating currents to the emitter coils, and simultaneously sampling current flows which pass through the emitter coils and a second current of the receiver coil. The method further includes determining coupling factors between the emitter coils and the receiver coils based on the determined current flows and voltages, and determining the object based on the coupling factors.
