Patent CA-2162654-A1 (CA)
Inventor: GIBSON ROBERT T
IPC: G01R15/12
Filed: 1995-11-10
Abstract: An electronic test instrument adapted for displaying only meaningful information notwithstanding the intermittent arrival of valid input signals due to probing operations is provided. Two independent measurement processes measure the input signal simultaneously. The first measurement process operates in a similar fashion to a digital storage oscilloscope (DSO) by successively sampling the input signal to produce waveform information which are selectively sent to an LCD display device which graphically displays the waveforrn. The second measurement process continually performs a stability assessment of the input signal by collecting a series of stability measurements of a selected input signal parameter, creating a moving average of the series, and comparing each new stability measurement to the moving average relative to stability criteria. The stability decision controls the flow of waveform information to the display, thereby ensuring that only meaningful information is displayed based on waveform scans conducted when the input signal is stable.

IPC: G01N33/00
Filed: 1994-07-27
Abstract: An internal combustion engine (360) is provided with a plurality of sensors to monitor the operation thereof with respect to various temperature measurements, pressure measurement, etc. A predictive model processor (322) is provided that utilizes model parameters stored in the memory (324) to predict from the sensor inputs a predicted emissions output. The model is strained with inputs provided by the sensor and an actual emissions sensor output. During operation, this predicted output on line (326) can be utilized to provide an alarm or to be stored in a history database in a memory (328). Additionally, the internal combustion engine (260) can have the predicted emissions output thereof peiodically checked to determine the accuracy of the model. This is effected by connecting the output of the engine to an external emissions sensor (310) and taking the difference between the actual output and the predicted output to provide an error. This is compared to a threshold and, if the error exceeds the threshold, the predictive model processor (322) can be placed in a training operation wherein new model parameters are generated. Additionally, retraining could take place external to the predictive model processor (322). During runtime, a control network (350) can be utilized to predict control parameters for minimizing the emissions output.
