Appeal No. 95-3565
Application 08/053,814
Claim 1 reads as follows:
1. A multiresonant traveling wave actuator comprising,
a multiresonant vibrator,
a movable object,
a means of providing a normal force to maintain a
contact between the object and the vibrator,
a controller to electrically activate an
electromechanical transducer, moving the object by traction with
negligible contact sliding,
the multiresonant vibrator having at least one
electromechanical transducer having a plurality of layers of
independently electrically addressable segments which receive
signals from the controller,
wherein the segments mechanically frequency sum to
produce waves in the multiresonant vibrator, the waves comprising
a longitudinal traveling wave having a contact area component for
engaging the object and a velocity component for moving the
object at a desired speed.
