Abstract

The light beam goes from a light-emitting diode (1) to a phototransistor (2). The modulation of the beam by cross-sectional irregularities of the yarn which are due to its texture is used as a useful signal, amplified (at 19), rectified (at 22) and applied to a latch (27) having two trigger thresholds. Application to stop motions.
