Korean researchers have confirmed that underground wireless communication is possible, moving beyond the terrestrial wireless ...

Abstract: This paper presents a monolithic optical encoder using CMOS image sensor (CIS) with background light cancellation. Both the absolute and incremental encoders are designed and fabricated on ...

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 ...

An optical illusion is dividing the internet over whether the picture is of pink slime or three forks laid out on a hot pink dish towel — and it’s making people’s brains hurt. Deemed as the “black and ...
