Title: Optical storage unit for electronic data
Inventor: MENZEL RALF PROF DR
IPC: G11B7/0065
Filed: 1996-11-04
Abstract: The optical storage unit uses materials with narrow absorption and emission bands with widths of less than 25 nm between values of 50 percent of the maximal band amplitude. Different data can be retrieved through suitable reading at different wave lengths. The different data are preferably provided by selective placement of different materials in a spatial distribution, which absorb and emit narrow bands at different frequencies. The materials are combined and placed in such way, that a reading of different data is possible at different wavelengths for each value of the data.

Title: Monitor for fault diagnosis in sensor measuring yaw in motor vehicle
Inventor: AKUTA YOSHIMITSU
IPC: G01P15/00
Filed: 1997-04-18
Abstract: A monitor for a fault in sensor (1), for yaw in a vehicle  controlled by a four-wheel steering system, compares the sensor output signal psi SENS with a value  psi KALM derived directly from the differing speeds of the non-driven wheels (4R,4L) during turning. The derived value  psi KALM is processed to take account of a number of relevant variables eg. steering (6) and rear-wheel (7) orientation and particularly the roughness of the terrain (14). The difference  psi S-ENS -  psi KALM is established by the module (2) and appears as an error  psi ER for comparison with one of two threshold levels  psi SHF in the diagnostic unit (3) depending on rough or smooth terrain.
