  • Magnetic encoder for reading marks on an associated magnetic track
    Patent number: 5821517
    Abstract: The encoder has at least one magnetoresistor (120, 220, 320, 322, 324, 326) and the magnetic support has a succession of magnetized regions (242, 342, 442), characterized in that the magnetic encoder also has a flux guide (154, 254, 354, 454), which has reading pole pieces (256, 256', 356) separated by at least one air gap (252, 352, 452) having a length (g) less than the smallest spacing of the magnetized regions.

  • Coder for measuring relative movements between two objects
    Patent number: 5719569
    Abstract: A coder includes a measuring rule (R3) carried by one object and having at least two tracks (X, Y). The tracks are provided with simple marks distributed in a substantially identical manner over the two tracks. At least two specific marks (M1, M2) are located on two distinct tracks. Each mark limit defines a spacing change on the measuring rule. At least two mark readers (LX, LY) are carried by another object, each associated with a track whose marks it detects. A processor is connected to the readers for determining the distance and direction of the movement. The invention is useful in robotics and metrology.
