Abstract: This invention encompasses embodiments for multi-modal integrated simultaneous measurement of various aspects of fluids contained in circulating systems such as automotive reciprocating engines and vehicle transmissions. These circulating systems perform constant internal lubrication, and heat and contaminant removal to protect the internal moving parts from the inherent friction and damage in normal operation. Most commonly this is achieved with fluids based on hydrocarbon and/or related synthetics, which, over time, can lose their protective properties, and vary in their performance or breakdown/decay due to internal and external events. Several components within the lubricant fluid can be measured and can provide insight into the efficacy of the system to perform its designed mission.

Abstract: The present disclosure provides systems and methods for calculating the flux in a core of an unloaded power transformer using current measurements taken from a capacitance-coupled voltage transformer (CCVT) attached to the same phase line as the power transformer. According to various embodiments, the current sensors may both be positioned at zero-voltage points in the CCVT, eliminating the need for high-voltage insulated current sensors. An intelligent electronic device (IED) may determine the magnetic flux within the core of the power transformer using the measured and/or derived currents through capacitive assemblies of the CCVT. The IED may calculate the residual flux in the power transformer when it is de-energized. The IED may use the calculated residual flux to facilitate an optimized re-energization of the power transformer, thereby reducing inrush currents during re-energization.

Abstract: A health monitoring system for a fuel cell stack using current fuel cell architecture to enable the electronic control unit (ECU) to continue to monitor the health of the fuel cell stack despite a component failure. The system uses an embedded measurement module (EMM) connected to a group of fuel cells in the fuel cell stack to monitor the health of that group of fuel cells. The EMM produces a pulse width modulation signal that is sent to the ECU. A total voltage value for the group of fuel cells is embedded into the calibration signal or end of frame sequence. The ECU uses an algorithm to determine a missing voltage of at least one fuel cell in the event of the component failure of that fuel cell by adding up the cumulative value for each fuel cell reporting their voltage and subtracting that value from the total voltage value found in the end of frame sequence.

Abstract: A test pattern is sequentially selected from an original test pattern sequence constituted by a plurality of test patterns including a don't care bit. Power consumption in each of regions obtained by substantially equally dividing a layout region of a semiconductor integrated circuit in a case where a don't care value is specified in the selected test pattern and this selected test pattern is applied to the semiconductor integrated circuit is estimated. A searching is conducted for a don't care value of the selected test pattern which minimizes a variation in power consumption among the regions by repeatedly changing the don't care value and repeatedly estimating power consumption in the regions. A new test pattern sequence constituted by a plurality of test patterns including no don't care bit is generated by defining the don't care value obtained by the searching as a don't care value of the selected test pattern.

Abstract: The disclosure relates to a method for reconstructing the source of an electromagnetic field. Firstly, a measurement space separate from the source is selected so that the measurement space is connected to the source via a magnetically homogeneous spatial region. Measured values of the electromagnetic field emitted by the source are recorded on the surface of the measurement space so that the electromagnetic field in the measurement space can be uniquely determined in the context of an error bound determined by the discreteness of the measured values. A mathematical model of the electromagnetic source is developed which has a multiplicity of unknowns, and a system of equations is set up that relates the unknowns of the model to the measured values. The system of equations is solved in order to determine the characteristics of the electromagnetic source. The disclosure also relates to an arrangement for carrying out the method.

Abstract: According to the present invention, a center deviation amount, which is an amount of deviation (distance) between the center line of a reference measurement target and the detection point is calculated using the reference measurement target having a known diameter, and a measurement value of a diameter of an arbitrary measurement target is corrected using the center deviation amount. Therefore, an accurate diameter value can be calculated even in the case of a measurement target having a diameter value different from the diameter value of the reference measurement target.

Abstract: A method of obtaining a consistent evaluation of the state of the system which has been monitored by measurement of multiple parameters of that system. The multiple parameters are used to calculate a single dimensional value based on the distance between the current state and normal states of the system using a Parzen Windows probability function. Consistent single dimensional values regardless of the dimensionality of the original data set can be obtained by finding a relationship between the single dimensional value and the probability of status of the system. Different relationships are obtained for different dimensionalities of data sets. Sensor malfunction can also be detected by testing the probability of the state implied by measuring all of the available parameters against the probability of the state implied by ignoring different individual ones of the parameters. A significant disparity in the two probabilities indicate possible sensor malfunction.
