Knobs are ubiquitous in technology user interfaces, but touchscreens are increasingly replacing them for interface controls. The latest project from [upir] combines a rotating knob with a touchscreen ...

Optical techniques are methods that use light to probe or control matter. One prominent example is optical spectroscopy, which includes such methods as pump–probe spectroscopy, Raman spectroscopy and ...

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 ...

Abstract: Following this paper, the design, implementation, and evaluation of an intelligent optical gas leakage detection system based on machine learning and an Arduino platform to enhance the ...
