    • A displacement estimation system (100 / 400 / 600) comprising a data acquisition system (106) and a processing system (108) is provided. The data acquisition system is configured to capture a first frame (112A) from a first substrate (102A) including a first pattern (104A) and a second substrate (102B) including a second pattern (104B) at a first time and capture a second frame (112B) from a third substrate (102A) including a third pattern (104A) and a fourth substrate (102B) including a fourth pattern (104B) at a second time subsequent to the first time. The first pattern and the third pattern are substantially identical, and the second pattern and the fourth pattern are substantially identical. The processing system is configured to calculate a first displacement (312) between the first pattern and the third pattern using the first frame and the second frame and calculate a second displacement (314) between the second pattern and the fourth pattern using the first frame and the second frame.

    • A new type of catalyst support with oxygen storage capacity (OSC) and methods of making the same are disclosed. The composition ratio is x(Ce 1-w Zr w 0 2 ) : yM : zL : (1 -x-y-z)AI 2 0 3 , where Ce 1-w Zr w 0 2 is the oxygen storage composition with stabilizer Zr0 2 , molar ratio (w) in the range of 0 to about 0.8, and a weight ratio (x) of about 0.05 to about 0.8; M is an interactive promoter for oxygen storage capacity with a weight ratio (y) of 0 to about 0.10; and L is a stabilizer for the support Al 2 0 3 with weight ratio (z) of from 0 to about 0.10. In some cases, M or L can act as both OSC promoter and thermal stabilizer. The weight percentage range of ceria-zirconia and other metal and rare earth oxides (x+y+z) is from about 5 to about 80% relative to total oxides. Combining platinum group metals (PGM) and adhesive with the catalyst supports, a new wash coat made therefrom is provided that comprises a mixture of catalyst support materials according to the relationship (a)RE-Ce- Zr0 2 + (3)CZMLA + (1 -a-β)RE-AI 2 0 3 , where RE-Ce-Zr0 2 is a commercial OSC material of rare earth elements stabilized ceria zirconia having a weight ratio (a) ranging from 0 to about 0.7; CZMLA is the catalyst support material of the present disclosure having a weight ratio (β) ranging from about 0.2 to about 1 such that (α+β) 2 0 3 is rare earth element stabilized alumina having a weight ratio equal to (1 -α-β). The new wash coat made therefrom exhibits a lower activation temperature compared with traditional formulation of wash coat by at least 50°C. The new wash coat made therefrom also requires less RE-Ce-Zr0 2 oxide and/or less PGM in the formulation of emission control catalyst for gasoline and diesel engines.
