  • Patent number: 10852357
    Abstract: A system and method is disclosed for analyzing a set of collected raw data point values and determining which one or ones of the values are erroneous data values. In one implementation of the method specific ones of the values are examined to determine if they are outliers, and if so they are removed from the data set. At least two other ones of the values obtained at points in time prior to a given one of the values are examined. Weights may be assigned to the at least two other values, and the weights used to help generate a predicted data point value. The predicted data point value is compared to the given one of the values to determine if the given one of the values is an erroneous value. In this way the integrity of each data point value in the set can be checked.

  • Patent number: 10811709
    Abstract: A method of controlling purge of a fuel cell system for a vehicle is provided. The method determines whether a purge function is normally performed in controlling purge of discharging nitrogen, hydrogen, and vapor within an anode of a fuel cell system. Particularly, the method confirms whether purge is performed by measuring a duty or a current applied to a hydrogen supply valve and measuring a change in the duty before and after an application of a purge valve operation command while adjusting a pressure inside the anode, which supplies hydrogen, to be uniform. Further, a hydrogen supply amount supplied into an anode is estimated and a change rate of a hydrogen supply amount supplied to the anode and a hydrogen amount consumed during a generation of the fuel cell system are estimated during a purge function, to determine whether purge is actually performed based on the estimated information.

  • Patent number: 10698023
    Abstract: A method and device for high speed broadband testing of systems and substances using a binary, spectrally sparse sequence (SSS) as a periodic excitation waveform. The sequences with controllable frequency and magnitude spectra content are designed by component manipulation method or by edge manipulation method. The excitation waveform is typically pre-calculated, and kept in waveform memory, from where it is shifted out into digital to physical quantity converter (DQC). The sparse spectrum of the SSS makes it easy to create plenty of uncorrelated frequency sets with adjacent, but sufficiently different frequencies to form multi-path test systems, where all the paths can be measured simultaneously. The response of the sample under test (SUT) is sampled and the complex transfer function is calculated directly or indirectly via Impulse Response by Discrete Fourier Transform technique and its derivatives. The sequence bit interval and sampling interval have a predetermined ratio.
