Abstract
Dispositif de surveillance de la pression d'un pneumatique de véhicule. Il comprend un oscillateur 2 à bobine oscillante fixé sur un côté du châssis du véhicule; un résonateur 1 constitué par une bobine de résonance et par un condensateur, fixé sur une partie périphérique de la roue portant le pneumatique, près de la bobine oscillante et de façon à entrer en résonance avec une onde électromagnétique rayonnée par cette bobine; une unité de traitement de signal comportant un détecteur 7 apte à déceler que les oscillations de l'oscillateur varient du fait que le résonateur prend et quitte l'état de résonance selon la pression régnant dans le pneumatique; et un avertisseur 3 engendrant un signal d'alarme d'après le signal de sortie de cette unité de traitement de signal. Application à la sécurité routière
