摘要： Embodiments herein are directed to a system and a method of selectively manipulating magnetically-barcoded materials from background magnetic materials. Magnetic barcodes include layers of magnetic anisotropy. These are then manipulated by a magnetic system that can drive spatio-temporal magnetic fields that can "match" a barcode to drive a specific interaction, thereby providing a "lock-key" interaction. This technique is able to selectively manipulate magnetically-barcoded materials, and can have applications across a variety of magnetic systems such as cell separation, drug delivery, valves, and motors.

摘要： An electronic circuit for measuring an angle and an intensity of an external magnetic field (60), comprising: a first and second magnetic field sensing unit (300, 400) having sensing axis substantially orthogonal to each other; a voltage generator (200) supplying a synchronization signal (101), a first voltage waveform (201) to the first magnetic field sensing unit (300) and a second voltage waveform (202) to the second magnetic field sensing unit (400); a signal conditioning unit (500, 600) configured for adding up the first (301) to the second sensing output signal (401) outputting a conditioned signal (601); wherein the first and second voltage waveforms (201, 202) have substantially the same amplitude and the same frequency and are phase shifted by about 90° with respect to each other; and wherein the conditioned signal (601) and the synchronization signal (101) are inputted into a magnetic field angle detection unit (700) configured for measuring a phase shift between the conditioned signal (601) and the synchronization signal (101) and for determining the angle of the external magnetic field from the measured phase shift. The electronic circuit is also for measuring an intensity of the external magnetic field and each of the first and second magnetic field sensing units comprises a magnetic tunnel junction and is configured such that an amplitude of the first and second sensing output signals varies linearly with a variation of the intensity of the external magnetic field, the electronic circuit further comprising a magnetic field intensity detection unit configured to determine the intensity of the external magnetic field by sampling the amplitude of the summed signal (501) at its maximum to obtain a corresponding sampled magnetic field intensity output (801), the occurrence of the maximum being detected based on the conditioned signal (601) being a digital phase comparator signal of the summed signal (501).

摘要： L'invention concerne un procédé de modification d'un fonctionnement d'un capteur magnétique pour moteur thermique de véhicule hybride en fonction du mode de propulsion. Lors d'une alternance d'un mode thermique (MT1, MT2) en électrique (ME), une unité de contrôle électronique envoie un premier signal en retour (S1) par l'alimentation filaire au capteur avec une configuration différente du signal d'alimentation de base (Salim) et ayant été préalablement mémorisée dans et reconnaissable par le capteur comme représentative d'un passage en mode de propulsion électrique (ME). Le capteur suspend un recalcul du seuil de commutation (SC) en gardant en mémoire le dernier recalcul du seuil de commutation (SC1) effectué avant réception du premier signal en retour (S1) et un envoi du signal électrique de sortie (Ss) vers l'unité de contrôle tant que l'unité de contrôle électronique n'envoie pas un deuxième signal en retour (S2) représentatif d'une reprise en thermique (MT2).

摘要： Sensors measure magnetic field components, and the measured fields are used to calculate and estimated transverse position of a longitudinal electric current flowing as an electric discharge across a discharge gap. Based on the estimated position, and according to a selected transverse trajectory or distribution of the estimated discharge position, magnetic fields are applied transversely across the discharge gap so as to control or alter the estimated discharge position. Inventive apparatus and methods can be employed, inter alia , during operation of a vacuum arc furnace.
