摘要： L'invention concerne le domaine technique de la détection magnétique. En particulier, elle concerne un détecteur de métal (100) pour la détection d'au moins un objet métallique exposé à un champ magnétique de détection. L'invention propose un détecteur de métal qui utilise un récepteur à architecture échantillonnée. En particulier, dans ce type d'architecture, on sépare l'opération d'échantillonnage des opérations de quantification et de codage. En comparaison, dans les architectures classiques, ces trois opérations sont habituellement réalisées en parallèle au niveau d'un convertisseur analogique numérique (CAN ou «analog to digital converter», ADC, en anglais). Dans le cadre d'une architecture échantillonnée, on réalise l'échantillonnage directement sur le signal de réception et on réalise la majorité du traitement de signal en temps discret (p. ex. par l'utilisation de systèmes à capacités commutées avec des interrupteurs MOS pour la commutation).

摘要： Die vorliegende Erfindung betrifft eine Beladungssensorik (10) für eine Transporteinheit (1) zur Beförderung von Transportgut (2), insbesondere in Form von ULDs zur Aufnahme von Gepäck, Frachtgut oder Post. Es wurde als problematisch gefunden, dass Transporteinheiten (1), wie sie im Bereich von Flughäfen, Bahnhöfen, etc. zur Beförderung von ULDs zum Einsatz kommen, oftmals im Freien stehen und bspw. durch Schnee, Eis oder sonstige Umwelteinflüsse beeinträchtigt werden, was die Verwendung üblicher Gewichtssensoren zur Detektierung von Transportgütern erschwert bzw. teils sogar unmöglich macht. Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Beladungssensorik für eine Transporteinheit zur Beförderung von Transportgut zu schaffen, die die vorgenannten Nachteile ausräumt und die eine absolut zuverlässige Detektion des Transportgutes erlaubt. Erfindungsgemäß umfasst die vorliegende Beladungssensorik (10) dazu mindestens einen Sensor (100) zur Detektion von Metall, welcher detektiert, sobald ein metallisches Transportgut (2) im detektierbaren Abstandsbereich auf der Ladefläche (11) der Transporteinheit (1) abgestellt wird.

摘要： An inductive sensing system (8) is adapted to apply electromagnetic excitation signals into a body, the system comprising a resonator circuit (10) incorporating a loop antenna (12). The system senses signals returned back from the body with the same antenna, based on variation in electrical characteristics of the resonator circuit. The system is configured for separating signals received from different physiological sources within the body. This is performed based on detecting in the resonator circuit electrical characteristics indicative of both a real and an imaginary part of an additional inductance component added to the antenna by received electromagnetic signals. The separating the signals from different physiological sources is based on relative magnitudes of said detected real and imaginary inductance components added to the resonator circuit by the returned signals.
