We gather in this note results and examples about collared or non-collared boundaries of non-metrisable manifolds. Almost everything is well known but a bit scattered in the literature, and some of it is apparently not published at all.

MaskClip: Detachable Clip-on Piezoelectric Sensing of Mask Surface Vibrations for Real-time Noise-Robust Speech Input
cs.SD 2025-05 conditional novelty 5.0 of 10

A detachable piezoelectric clip on a face mask reads speech vibrations through the mask material, achieving 6.1% character error rate in noise versus 19.7% for a conventional pin microphone.
