Patent EP-0085148-A3 (EP)
Title: Arrangement for error correction in position-measuring systems
IPC: G01D3/02
Filed: 1982-11-19
Abstract: An error correction system for correcting machine errors or division errors in a position measuring instrument for precision machines is disclosed. The system is usable, for example, in conjunction with instruments for measuring the relative position of two objects, wherein an incremental grid division formed on a measuring scale is scanned by a scanning unit to generate analog measurement signals. According to this invention, the scale defines additional correction tracks which extend along the scale, parallel to the division, and are scanned by additional scanning elements included in the scanning unit. These additional scanning elements operate to generate analog correction signals from the correction track. These analog correction signals are used to correct the analog measurement signals with respect to errors such as amplitude errors, phase angle errors, and zero crossing errors.

IPC: G01S5/20
Filed: 1984-12-12
Abstract: The invention relates to a system for localizing a ground 
impact wave source, including at least three sensors (11-22) 
which are sensitive to impact waves generated in the 
ground, there being means (3-7) arranged for calculating the 
position of the impact wave source from impact wave 
information received by the sensors. In accordance with the 
invention the sensors are placed conventionally under the 
ground surface, and means (24-28) for calculating the 
position of the impact wave source include means for 
detecting the characteristics of the impact waves. Calculating 
circuits are arranged for comparing the impact wave charac­
teristics received by each sensor with a theoretical model for 
these characteristics stored in a memory (6), the calculation 
circuits also including means for calculating the deviation 
between the measured characteristics and the stored charac­
teristics starting from an assumed position for the impact 
wave source. The deviation is caused to assume successively 
decreasing values by stepwise transfer of the assumed 
position of the impact wave source, which for a minimum 
value of the deviation will substantially coincide with the 
actual position of the impact wave source.

Title: Defect skipping mechanism for disk drives
IPC: G11B20/18
Filed: 1988-07-05
Abstract: A novel technique for skipping defects on a magnetic or writable optical disk is described. The technique includes a sector format comprising a header (24) and data area (28), wherein the data area can include one or more "bad areas" (108, 116) which will be skipped when data is being written to or read from the sector. The bad areas are variable in size and may be located anywhere in the data area, including in an EDAC. The header includes a defect descriptor (48) comprising a defect pointer (70, 72) for each of the bad areas supported. Each defect pointer contains a value (74, 78) indicating the number of bytes in the good data area (106, 114) preceding the bad area pointed to by the defect pointer, and a value (76, 80) indicating the number of bytes in the bad area. The value indicating the number of bytes in a good area is set to a value indicating a number of bytes as least as large as the sector size if there is no subsequent bad area in the data area. A method for reading or writing data to a sector formatted as above is also described. A method for formatting a disk as above is described as well.
