Abstract
Devices (40) are provided with sensor arrangements (41) comprising field generators (42) for generating magnetic fields, field detectors (43) comprising magnetic field dependent elements (51-58) for detecting components of the magnetic fields in planes of the elements (51-58), and movable objects (44) for, in response to accelerations of the movable objects (44) parallel to the planes, changing the components of the magnetic fields. Length axes of the magnetic field dependent elements (51-58) make angles between minus 80 degrees and plus 80 degrees with the components to be detected. Means for forcing the movable objects (44) into rest positions comprise elastic material (59) or fixed objects (46) whereby one of the objects (44,46) comprises the field generator (42) and the other comprises magnetic material or a further field generator (50).
