Method for determining motion using a segment meter and a fine position sensor

摘要

The method involves detecting translational and rotatory movements of a body by converting count value of a segment counter with the position value of a fine position sensor (21) into a total position value. The information required for synchronization is obtained from the last magnetization direction of the pulse wire (Wg1) and the information about the last determined segment is obtained from the memory. The magnetization direction of the pulse wire is determined by external defined energization of a coil (Sp1) and measuring reaction on another coil (Sp2) of the pulse wire sensor (Ws1,Ws2). Independent claims are included for the following: (1) an arrangement for synchronization of an absolute segment counter; and (2) a device for synchronization of an absolute segment counter.
