Abstract
Παρουσιάζεται μια συσκευή αισθητήρα-θέσεως, που περιλαμβάνει μιαν ομάδα ακτινοβολητών, οι οποίοι είναι προσαρμοσμένοι για να τοποθετούνται σε αντίστοιχες θέσεις πλησίον ενός σώματος ενός υποκειμένου και να δημιουργούν πεδία ηλεκτρομαγνητικής ενέργειας. Ένας αισθητήρας καθορισμού θέσεως, είναι προσαρμοσμένος ώστε να παράγει σήματα αισθητήρα σε απόκριση των πεδίων ενεργείας. Ένα ή περισσότερα στοιχεία αναφοράς, είναι προσαρμοσμένα για να τοποθετούνται σε αντίστοιχες θέσεις πλησίον του αισθητήρα και να παράγουν σήματα αναφοράς σε απόκριση των πεδίων ενεργείας. Μια μονάδα ελέγχου είναι προσαρμοσμένη για να καθορίζει, για καθένα των στοιχείων αναφοράς, αντίστοιχες μη αλλοιωμένες παραμέτρους αναφοράς, σε απόκριση προς τις γνωστές θέσεις των στοιχείων αναφοράς. Η μονάδα ελέγχου επιπροσθέτως δέχεται τα σήματα του αισθητήρα και τα σήματα αναφοράς, και υπολογίζει ένα σφάλμα στοιχείου αναφοράς για κάθε στοιχείο αναφοράς, σε απόκριση μιας αλληλεπίδρασης ενός μεταλλικού αντικειμένου με τα ενεργειακά πεδία, τις μη αλλοιωμένες παραμέτρους αναφοράς του στοιχείου αναφοράς, και του σήματος αναφοράς που παράγεται από το στοιχείο αναφοράς. Τότε, η μονάδα ελέγχου υπολογίζει μια θέση του αισθητήρα, σε απόκριση των σημάτων του αισθητήρα και των σφαλμάτων του στοιχείου αναφοράς.
