Abstract: An intelligent gas flow sensor probe which outputs a state signal indicating whether there is forced gas flow present within a conduit or whether there is no gas flow. The intelligent gas flow sensor probe includes a heated thermistor and a reference thermistor functionally coupled to a microcontroller. The heated thermistor is continuously heated at a constant rate to a temperature above an ambient temperature within the conduit and outputs a signal responsive to a change in temperature induced by gas flow incident thereupon. Gas flow within the conduit causes heat to be transferred from the heated thermistor to the gas flowing over and/or around the heated thermistor. The reference thermistor is thermally insulated from the heated thermistor and outputs a reference signal responsive to an ambient temperature of the gas within the conduit.

When the gas sensor readings stay above the background gas concentration range for a defined long dwell time (longer than the maximum expected interval between excursions to the background gas concentration), a downwards calibration adjustment is effected.

A set of data is selected from the plurality of intensity measurements that includes a peak. Confidence values are assigned to each data point in the set of data producing a plurality of confidence value weighted data points. A peak predictor is selected. The peak predictor is applied to the plurality of confidence value weighted data points of the peak that have confidence values greater than a first threshold level using the prediction module, producing predicted intensities for data points of the peak not measured and/or measured data points of the peak that have confidence values less than or equal to a second threshold level. The confidence values can include system confidence values, predictor confidence values, or any combination of the two.

Abstract: Surface wrapping is a semi-automatic approach for segmentation of a geobody bounding surface within volumetric data. The approach is metaphorically based upon the concept of collapsing an elastic surface onto a physical object. The desired output of the process is a polygonal mesh that may be stored as data, displayed to the end user, or used in further data processing techniques. This approach has advantages over fully automated segmentation algorithms in that it may be applied to data where the volume to be segmented is not fully imaged, or where a high level of noise is present. This approach is also significantly less time consuming for the human analyst than fully manual segmentation techniques, in that the user need only define an approximate initial bounding surface prior to application of the algorithm which determines a more detailed and accurate bounding surface.

Abstract: A system and methods for determining points for an algorithm to calculate the frequency of a waveform measured from a monitoring device. Data points are measured from the waveform. A last point of interest from the previous cycle of the waveform is referenced. Four points of interest at equally spaced phase angles from the current cycle of the waveform are determined by calculating the average of the data points around each of the respective equally spaced phase angles of the current cycle of the waveform. The average value of the points of interest in the current cycle is subtracted from the four points of interest and the last point of interest from the previous cycle to compensate for DC bias. A frequency of the waveform is determined based on the determined four points of interest of the current cycle and the last point of interest from the previous cycle. The correction factor for determining sample frequency may be reduced for subsequent cycles in order to increase stability.

Abstract: A method of monitoring soot mass in a particulate filter of an exhaust system includes determining a pressure differential across the filter, obtaining a first soot mass estimate by fitting the determined pressure differential to a first stored database of measured or modeled pressure differentials and corresponding measured soot masses taken during filter regeneration using a substantially similar filter previously loaded following a complete filter regeneration, and obtaining a second soot mass estimate by fitting the determined pressure differential to a second stored database of measured or modeled pressure differentials and corresponding measured soot masses taken during filter regeneration using a substantially similar filter loaded following an incomplete filter regeneration. Actual soot mass is estimated by calculating a weighted sum of the first and second soot mass estimates with weighting based on operating parameters indicative of regeneration efficiency.
