The amount of ink is determined using both a first vibration frequency VF1 that is measured when a driving signal DS1 of a first frequency is provided to a sensor, and a second vibration frequency VF2 that is measured when a driving signal DS2 of a second frequency F2, which is less than the first vibration frequency by a specific ratio, is provided to the sensor. When there is an incorrect measurement of either the first vibration frequency VF1 or the second vibration frequency VF2, the natural frequencies to which the vibration frequencies are near will be different, as shown in the combination numbers “2” and “3” in the Ink Amount of Determining Table 600. Because the cases wherein the vibration frequency is measured incorrectly are the cases wherein there is no ink, when the first vibration frequency VF1 and/or the second vibration frequency VF2 is near to the target natural frequency H2 (combination numbers “2” through “4”), it is determined that the amount of ink is stored in the cartridge being processed is less than a specific amount.

A properly calibrated load-cell is critical for the safe operation of a rod-pumping system. Load readings are utilized for shutdown thresholds, and incorrect measurements can cause those safe load limits to be exceeded. Correct surface load, combined with position measurement, is also important for the diagnosis of the complete pumping system. The diagnostic method for calculating down-hole conditions presents an interesting opportunity to validate surface load measurements, even from the incorrect load measurements themselves. The calculated down-hole dynamometer card will be transposed on a distinct diagonal with respect to both load and position, if the input surface load measurements are incorrect. A load offset can then be identified from this shifting and the surface load measurements can be corrected. Calculated pump cards have been traditionally aligned with the surface dyno card position, and so this diagonal pump card shifting correlation with incorrect, or unexpected, surface load has not been realized.

Disclosed is a precise step counting method using human body capacitance, relating to the field of electronic communications, and in particular to a method for implementing precise step counting using human body capacitance. At present, a wearable intelligent device having a step counting function measures a number of steps by means of an inertial sensor, but has limited precision in a measurement result. Due to the complexity of motion of a human body, missed measurement and incorrect measurement often occur in the inertial sensor-based measurement of the number of steps. The recognition and calculation of the number of steps also occupy a large number of hardware resources. In this respect, a precise step counting method based on human body capacitance, a human body's electrostatic field, or a human body surface potential is provided. When a human body is walking, the actions of leg lifting and leg lowering would change human body capacitance, and the number of steps can be conveniently and quickly measured by detecting a change in a physical signal caused by a change in the human body capacitance, such as a change in a voltage signal of human body skin and a change in a frequency. The method implements precise step counting without occupying hardware spaces and resources, has the advantage of low power consumption, and can be embedded into all current wearable intelligent devices that require a step counting function).

While determining a leak resistance (Ra, Rb) of a subscriber connection line (TAL) provided, for example, with two wires (a, b) in a communications network, a capacitor (C) connected between said two wires is discharged prior to measuring leakage currents (IRa1, IRa2). For this purpose, prior to be connected to a high resistance of the other wire (b), the measurable wire (a) and the other mentioned wire (b) are supplied with a constantly falling and increasing voltage (UaG, UbG). For that, the final value of said tensions (UaG, UbG) is determined in such a way that, when the connection to the high resistance of the other wire (b) is produced, the voltage of said wire (b) is equal to 0 volt. The leakage current is measured only when the discharge process is over, thereby making it possible to avoid an incorrect measurement caused by a current coming from the capacitor (C).

Before technical components are further processed, they are checked for the functionality thereof. In this case, an incorrect judgment of the functionality can occur due to measurement errors or incorrect measurements, which in turn results in a very inefficient test. The invention provides a method and a device by which an increased measurement accuracy can be achieved. This is achieved in that at least one first electrical voltage value is measured at a first constant measurement current and at least one second electrical voltage value is measured at a second constant measurement current at terminals of the component. Every measured voltage value is scaled respectively using a profile factor PF to form a measured value M, and only measured values M that are located at least with a tolerance range in a common value range are used for the determination of an electrical parameter.
