Patent ID: 11319190

Abstract:
A passenger conveyance system (2, 102, 202) is provided which includes a first component (12, 112, 212) arranged to rotate about a first rotation axis A1 and a second component (16, 116, 216) arranged to rotate about a second rotation axis A2; at least one magnet (20,120, 220); and at least one sensor (24, 124, 224). Either the at least one sensor (24, 124, 224) or the at least one magnet (20, 120, 220) is fixed to the first component (12, 112, 212). The sensor (24, 124, 224) is arranged to measure a displacement to the at least one magnet (12, 112, 212), and the system (2, 102, 202) is arranged to use the measured displacement to determine information indicative of the alignment of the first and second components (12, 112, 212; 16, 116, 216).
