CA 2506745

Quick release bolt assembly (10) included shank (12) and head (14) of larger cross-section than that of shank (12). The screw thread of shank (12) is adapted to rotatably engage with a complementary screw thread in a nut. Disengagement means are adapted in use to disengage the head (14) or the nut without rotation of the nut or shank (12). The disengagement means includes a material (18) such as shape memory alloy or epoxy resin, adapted to change form to facilitate engagement when activated. Activation may take place by a direct power supply or remotely by a radio frequency, magnetic, ultrasonic or infra red signal. Bolt (10) can be used for anchoring seat belts. Computer systems and methods for the identification of a target, including enquiring as to the status of the target and having means to command the target to change the status are also disclosed and claimed.

Un ensemble boulon (10) à libération rapide comprend une tige (12) et une tête (14) d'une section transversale plus grande que celle de la tige (12). Le filetage de la tige est conçu de façon à s'emboîter par rotation de manière complémentaire avec un filetage d'écrou. Un organe de dégagement est conçu de façon à dégager en utilisation la tête (14) ou l'écrou sans tourner cet écrou ou la tige (12). Cet organe de dégagement comprend un matériau (18) tel qu'un alliage à mémoire de forme ou qu'une résine époxy, conçu pour changer de forme afin de faciliter l'emboîtement lorsqu'il est activé. Cette activation peut être obtenue par une alimentation électrique directe ou à distance par un signal de fréquence radio, magnétique, ultrasonique ou infrarouge. Ce boulon (10) peut être utilisé pour fixer des ceintures de sécurité. Cette invention concerne aussi des système informatiques et des procédés d'identification de cible, comprenant la demande du statut de la cible et possédant un organe permettant de commander le changement du statut de la cible.
