Definitions
- EP-A-0 422 481 a method for the capacitive readout of planar, conductive structures is described. To read the structures, however, a constant feed rate of the data medium to be read is required. At varying speeds, this method is unable to read the information safely.
- Linking the information tracks formed and the data code is determined by an interpretation of the information tracks in consideration of the clock signal.
- the electrically conductive member is electrically conductive
- Material of conductive polymers in particular of PEDOT or PANI.
- the information tracks can in particular form a line sequence.
- Reading unit according to a first embodiment
- the clock electrode 5 and the center electrode 6 are used, while for reading the information track 3, the data electrode 7 and the center electrode 6 are used.
- the data carrier 1 is inserted in the direction of the arrow 9 in the reading unit 4.
- Clock signal then yields the following binary data code 12: 0 1 0 1 1 1 1 0 1.
- the data signals 16, 17 shown in FIG. 4 result for the two information tracks 2, 3.
- the maximum change in the reading speed is limited in this method. If the reading speed changes too fast, it may not be possible to reconstruct the true course of timing in the flaws. The condition, how often the state "0" may occur in sequence, must be redefined for each use case of the method. It essentially depends on how fast the reading speed can change.
