A permanently magnetized magnet associated with the bearing provides a magnetic field which is detected by a detector in the bearing. The relative rotation of one part of the bearing, such as a rotatable shaft or rotatable race, with respect to a second part of the bearing, such as a race, is indicated by the detector.

A variable stiffness bearing utilizing piezoelectric means for applying a variable preload force to the bearing. The preferred embodiment employs piezoelectric wafers having alternating power and ground connections to the wafers to allow the wafers to distort in direct proportion to the potentials applied. Increased potentials result in greater distortion, more preload force, and a stiffer bearing.

Bearing with adjustable stiffness

An X-Y position indicator control for manual movement over any surface to move a cursor over the display on a cathode ray tube, the indicator control generating signals indicating its position to cause a cursor to be displayed on the tube at the corresponding position. The indicator control mechanism contains X-Y position wheels mounted with their axes in perpendicular planes, which rotate according to the X and Y movements of the mechanism. As the position indicator control is moved along a surface each position wheel is resiliently urged into contact with the surface.
