Escalators and lifts, sentence 13

Lift doors use sensors, often a curtain of invisible light beams, or a rubber edge, to open again if something is in the way; never stop the doors with hands or feet, wait for the next lift.

Who acts: Lift doors, something · What happens: use, open, be, not stop, wait · To what, where: sensors, way, doors

The tree: Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R5-strong ×2. The frames are read from the tree by Mova's frames reader (prag) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
