Abstract: A motor characteristic inspecting device is capable of inspecting the condition of a motor installed in an apparatus without removing the motor from the apparatus. The motor characteristic inspecting device includes: a vector variation computing section configured to compute a voltage vector variation amount when a mover of a three-phase motor is moved by an external force; a speed variation detecting section configured to detect a speed variation amount; a constant computing section configured to compute a counter electromotive force constant; and a result display section. Armature windings of the motor installed in the apparatus and the motor characteristic inspecting device are electrically connected with power supply lines disconnected from the motor. An external force is applied to the mover of the motor. The condition of the motor is determined based on the computed result displayed on the result display section of the motor characteristic inspecting device.

Abstract: A method and system for estimating reservoir pressure in a hydrocarbon reservoir from downhole pressure measurements of producing wells is disclosed. Pressure measurements are obtained from wells in the production field over time, and communicated to a server that applies the pressure measurements for a well to a model of that well. The server operates the model using the pressure measurements to determine an operating mode of the well, such as producing or shut-in. Upon detection of a change in operating mode indicative of an abrupt change in flow at the well, such as corresponding to a shut-in event, additional downhole pressure measurement data is acquired until a steady-state condition is reached. The pressure measurements are used to determine a reservoir pressure, which is transmitted to a responsible reservoir engineer or other user. Modification of the determined reservoir pressure value by the user can be received, and the stored reservoir pressure and well model are updated accordingly.

Abstract: Electrochemical Impedance Spectrum data are used to predict pulse performance of an energy storage device. The impedance spectrum may be obtained in-situ. A simulation waveform includes a pulse wave with a period greater than or equal to the lowest frequency used in the impedance measurement. Fourier series coefficients of the pulse train can be obtained. The number of harmonic constituents in the Fourier series are selected so as to appropriately resolve the response, but the maximum frequency should be less than or equal to the highest frequency used in the impedance measurement. Using a current pulse as an example, the Fourier coefficients of the pulse are multiplied by the impedance spectrum at corresponding frequencies to obtain Fourier coefficients of the voltage response to the desired pulse. The Fourier coefficients of the response are then summed and reassembled to obtain the overall time domain estimate of the voltage using the Fourier series analysis.

An association of the unassignable measuring points and the structural elements is created and a corresponding transformation of the superimposed associated measuring points and structural elements is performed.
