Emitting, receiving and shifting are repeated until the emission subregion (11a-p) extends up to the second end at the start of the shifting step. A signal course is compiled from the received light signals, and the detection of the edge from the signal course is carried out.Type: GrantFiled: February 22, 2021Date of Patent: February 20, 2024Assignee: BALLUFF GMBHInventors: Juri Schroffenegger, Sergej Hense
