Title: Gas sensor
Inventor: WATANABE YUSUKE
IPC: G01N27/409
Filed: 2017-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress a reduction in the accuracy of detecting a specific gas concentration attributable to a control voltage for drawing while drawing oxygen to the periphery of a reference electrode.SOLUTION: A gas sensor of the present invention comprises a reference gas adjusting pump cell and a pump cell for measurement. The reference gas adjusting pump cell applies a control voltage Vp3 that repeatedly turns on and off to between a reference electrode and a measurement object gas-side electrode and draws oxygen to the periphery of the reference electrode. As the control voltage Vp3 turns on, a first period (time t3-t5) is generated in which a voltage Vref between the reference voltage and the measurement object gas-side electrode is large. As the control voltage Vp3 turns off, a second period (time t6-t7) is generated after a fall of the voltage Vref from the first period. The pump cell for measurement detects an NOx concentration on the basis of a voltage between the measurement voltage and the reference voltage during the second period.SELECTED DRAWING: Figure 3

Title: Method and device used in predicting nonsteady time series data
Inventor: JOSEPH TOWNSEND
IPC: G06Q10/04
Filed: 2017-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a method for predicting nonsteady time-series data by a computer.SOLUTION: In a next time step following a current time step, a neural network repeatedly executes a prediction cycle for outputting a predicted value of nonsteady time-series data. The value of time-series data is known up to the current time step, and, in each of prediction cycles, an input to the neural network is dynamically selected by executing an input selection process in each of time steps. The input selection process determines, with regard to a candidate designator set where each of candidate designators can be correlated to time-series data, causality between the value of time-series data and the value of each of designators in the candidate designator set, using a prescribed causality index, and selects a designator subset that should be an input to the neural network from designators of candidate designators calculated so as to produce a highest correlation with the time-series data in the current time step.SELECTED DRAWING: Figure 1
