Abstract: A three-dimensional data set is accessed. A two-dimensional plane is defined that intersects a space defined by the three-dimensional data set. The two-dimensional plane defines a two-dimensional data set within the three-dimensional data set and divides the three-dimensional data set into first and second subsets. A three-dimensional view based on the three-dimensional data set is rendered on such that at least a portion of the first subset of the three-dimensional data set is removed and at least a portion of the two-dimensional data set is displayed. A two-dimensional view of a first subset of the two-dimensional data set also is rendered. Controls are provided that enable visual navigation through the three-dimensional data set by engaging points on the multi-touch display device that correspond to either the three-dimensional view based on the three-dimensional data set and/or the two-dimensional view of the first subset of the two-dimensional data set.

Abstract: Various systems and methods are described for controlling an engine in a vehicle during engine operation, the engine having an exhaust and a NOx sensor coupled in the engine exhaust. One example includes correcting the NOx sensor to account for transients in exhaust gas flow, such as transients in exhaust gas flow rate.

In this way, even during such transients, accurate NOx readings are still available.
