Abstract: Condition monitoring of rotating machinery under low- and variable-speed conditions is a hot and difficult issue. Compared with vibration signals, optical encoder signals have the advantages ...

Have you ever come across those mind-bending images on social media and wondered, "Am I seeing things?" Well, aptly called optical illusions, these are simple and fun tests that work as an exercise ...

Abstract: This paper proposes an absolute positioning method for distance encoding by fusing reference signals with incremental signals. Reference marks with extinction characteristics are embedded in ...
