Abstract[English]
Systems, methods, and computer readable media are disclose for protecting vehicle passengers from magnetic field radiation. Protecting vehicle passengers from magnetic field radiation may include a passenger cabin; a wire cable configured to carry electricity during vehicle operation thereby generating a primary magnetic field that, in an absence of cancellation, would radiate into the passenger cabin; a current sensor associated with the wire cable, for sensing current through the wire cable; a cancellation wire, running along the wire cable; and an amplifier configured to receive a signal indicative of current running through the wire cable and for generating, within 1500 microseconds, a cancellation current for application to the cancellation wire, the cancellation current is within 30% of the current passing through the wire cable in order to cause a cancelling magnetic field thereby at least partially eliminating magnetic radiation from the wire cable to the passenger cabin.[French]
L'invention divulgue des systèmes, des procédés et des supports lisibles par ordinateur permettant de protéger des passagers d'un véhicule contre un rayonnement de champ magnétique. La protection des passagers d'un véhicule contre un rayonnement de champ magnétique peut faire intervenir une cabine passagers ; un câble métallique conçu pour transporter de l'électricité pendant le fonctionnement du véhicule, générant ainsi un champ magnétique primaire qui, en l'absence de suppression, émettrait des rayonnements en direction de la cabine passagers ; un capteur de courant associé au câble métallique, conçu pour détecter un courant traversant le câble métallique ; un fil de suppression, s'étendant le long du câble métallique ; et un amplificateur conçu pour recevoir un signal indiquant un courant traversant le câble métallique et pour générer, en 1500 microsecondes, un courant de suppression qui sera appliqué au fil de suppression ; le courant de suppression est dans les 30 % du courant traversant le câble métallique afin de provoquer un champ magnétique de suppression, éliminant ainsi au moins partiellement le rayonnement magnétique du câble métallique en direction de la cabine passagers.
