Abstract

1415092 Intruder detectors; road vehicle signalling W JANK 11 Jan 1973 [15 Jan 1973] 1489/73 Headings G4N and G4Q An intruder detector comprises an electrode at least partially surrounded by a solid dielectric envelope which is deformable by an intruder or by passage of a vehicle to produce a change in electrostatic potential. More than one electrode may be included in the dielectric envelope.
