摘要： A magnetic scale (4;62) for magnetic encoder apparatus is described. The magnetic scale (4;62) comprises a scale member having a plurality of grooves (16,18;42,44). The scale member defines a passive magnetic scale track that can be read by an associated magnetic scale reader unit (6;76). The plurality of grooves include grooves of at least a first groove type (16,42) and a second groove type (18,44), the magnetic properties of the scale member in the locality of grooves of the first groove type (16,42) being different than the magnetic properties of the scale member in the locality of grooves of the second groove type (18,44). The scale member is arranged to carry or encode absolute position information in the form of at least one codeword comprising a sequence of data bits, wherein each of the data bits is provided by a groove of the scale member, the data bit taking a first value (1) if the groove is of the first groove type (16,42) and a second value (0) if the groove is of the second groove type (18,44). The midpoints of the plurality of grooves (16,18;42,44) are substantially equidistantly spaced apart along the length of the scale member (4;62). Incremental and absolute position information can thus be extracted from the magnetic scale (4;62).

摘要： A scale (10) has magnetic incremental scale marks in a track (10a), and a pseudo-random code sequence in a reference mark track (10b). Sensors (2, 3) feed the pattern of the code in the track (10b) into a bi-directional shift register (18). So that a user can select any desired position for use as a reference mark, a memory (24) is provided, into which any selected code value can be pre-stored. A comparator (26) then compares the code value in the shift register (18) with the code value in the memory (24) and outputs a reference mark signal (Ri) when they match.

摘要： A readhead (6;76) is described for reading an absolute scale (4;40;50;80), optionally a passive magnetic scale, that encodes a series of data bits. The readhead includes a plurality of sensors, such as an array of Hall sensors (30;82), for producing a plurality of sensor signals (H). A plurality of signal combiners (84) are also provided to receive at least two of the sensor signals and produce therefrom a combined sensor signal (S). A plurality of data bit extractors (86) are arranged to receive at least two combined sensor signals (S) and to determine the value of a data bit encoded in an associated absolute scale (4;40;50;80). The readhead (6;76) also comprises an incremental signal generator (88,90) for generating at least one incremental signal (Sin/Cos) from the combined sensor signals (S) produced by a plurality of the signal combiners (84). In this manner, both absolute and incremental position is measured.

摘要： A scanning device ( 150) for a position encoder is described that comprises a plurality of sensor elements (16;H) for generating a plurality of sensor signals (S). A summation unit (34) is also provided for generating at least a first summation signal (Sin) and a second summation signal (Cos) that provide information on the relative alignment of the scanning device and an associated scale (14;152). The first summation signal (Sin) is generated from a first subset of the plurality of sensor signals (S) and the second summation signal (Cos) is generated from a second subset of the plurality of sensor signals (S). The plurality of sensor elements (16;H) are substantially evenly spaced apart from one another and N sensor elements are provided per period (p) of an associated scale (14), wherein N is an integer value and a multiple of three and four, hi this manner, the third harmonic contribution to the summation signals (Sin/Cos) is suppressed.
