摘要： A reading circuit for a magnetic-field sensor, generating an electrical detection quantity as a function of a detected magnetic field and of a detection sensitivity, is provided with an amplification stage, which is coupled to the magnetic-field sensor and generates an output signal as a function of the electrical detection quantity and of an amplification gain. In particular, the amplification gain is electronically selectable, and the reading circuit is moreover provided with a calibration stage, integrated with the amplification stage and configured so as to vary a value of the amplification gain in such a way as to compensate a variation of the detection sensitivity with respect to a nominal sensitivity value.

摘要： An assembled battery module includes battery cells connected in series, resistors, a voltage measuring unit, failure detection switches, and a control unit. Each resistor is connected between a positive or negative electrode of the corresponding battery cell and a corresponding node for the positive or negative electrode. Each failure detection switch is connected between the two nodes corresponding to positive and negative electrodes of a battery cell to allow on-off switching between the two nodes. The control unit detects a disconnection between a positive or negative electrode of a battery cell to a corresponding node based on first and second voltages measured between two nodes, the first voltage being measured when one of the two failure detection switches connected to the corresponding node is switched from on to off and the second voltage being measured when the other failure detection switch is switched from on to off.

摘要： A method of wear detection of a coated belt or rope includes measuring an initial electrical resistance of one or more cords, strands or wires of the coated belt or rope. The initial electrical resistance is calibrated by repeating the measuring of initial electrical resistance and populating a database with the measured initial electrical resistance values. A true initial resistance is determined from the population of initial electrical resistances and subsequent measured values of electrical resistance of the one or more cords, strands or wires of the coated belt or rope.

摘要： A method for enhancing inspection of components of specific geometry based on Barkhausen noises. The method includes specifying a first calibration curve that is independent of the component geometry, which describes the relationship between surface hardness values and measured Barkhausen noise signals. A first noise signal is determined by the measuring device for a reference component having the specified geometry and a first hardness value. A second noise signal is determined for a second reference component, having the specified geometry and a second hardness value lower than the first. A second calibration curve is determined, in which the first calibration curve is fitted to the first noise signal at the first hardness value and to the second noise signal at the second hardness value, such that using the second calibration curve, the measured noise signal of a component having the specified geometry relates with a surface hardness value.

摘要： A TMR element and a corrective AMR element are series-connected between a power supply and a ground. The resistance value of the corrective AMR element is set so as to offset an output error in the rotation angle of an external magnetic field, which is included in the resistance value of the TMR element. The resistance value of the corrective AMR element is smaller than that of the TMR element. An increased voltage can be applied from the power supply to the TMR element. It is possible to increase, in the resistance value of the TMR element, the amount of change that depends on the rotation angle of the external magnetic field. This makes it possible to increase, in the output of a magnetic sensor, the amount of change that depends on the rotation angle of the external magnetic field. The sensitivity of the magnetic sensor can be increased.

摘要： Disclosed is an isolation resistance measuring apparatus having a fault self-diagnosing function. The isolation resistance measuring apparatus having a fault self-diagnosing function forms a diagnosis circuit by means of a first isolation resistance measuring unit and a second isolation resistance measuring unit respectively connected to a cathode terminal and an anode terminal of a battery, and includes a control unit for determining whether a fault arises at the isolation resistance measuring apparatus by using a circuit equation derived from the diagnosis circuit and first and second diagnosis voltages. Therefore, the isolation resistance measuring apparatus may diagnose whether a fault arises at a device which measures isolation resistance of a battery.
