Title:
ANGLE-MEASURING DEVICE AND LINE OF PRODUCTS COMPRISING SAID ANGLE-MEASURING DEVICES
Document Type and Number:
WIPO Patent Application WO/2009/129891
Kind Code:
A3
Abstract:
The invention relates to the standardization of angle-measuring devices. A scanning device (20) is designed in such a manner as to be suitable for scanning a first closed code (C1) and a second closed code (C2). The second code (C2) is a joined section (V) of subsequent code elements (A3 to A13) of the first code (C1). The angle-measuring device comprises a scanning device (20), the decoding device (30) of which can be operated in a first or in a second mode of operation depending on an identification (ID) which defines the codes (C1, C2) to be decoded in such a manner that they are distinct. In the first mode of operation, the first code (C1) is decoded by a decoding table (T2) having a first and a second set of values. In the second mode of operation, the section (V) of the second code (C2) which corresponds to the first code (C1) is also decoded by the first set of values of the decoding table (T2) and the new sequence of code elements of the second code (C2), which is formed at the joint (ST2) by joining the section (V) taken over from the first code (C1), is decoded by an additional small decoding table (T5) having a third set of values.
