SPECIALIZED ACTUATORS DRIVEN BY OSCILLATORY TRANSDUCERS

摘要

Actuators (96) for power driven accessories for moving objects, such as vehicle power windows, windshield wipers, vehicle power antennas, power side view mirrors (86), catheter drivers, curtain moving machines, bi-directional rotary motors, thruster mechanisms that move relative to a reaction surface or that drive a driven member relative to itself, use orthogonal oscillatory transducers cooperatively to drive intermediary elements to move these objects bi-directionally along constrained paths. The actuators may also power a pneumatically driven autonomous robot element using dual pneumatic DSES elements such as planar contact surfaces with an array of apertures which are cyclically switched from a source of compressed air which acts as a lubricant to greatly reduce surface friction to a vacuum source, which acts as a clamping medium increasing contact frictional force. Orthogonal bladders are cyclically pressurized or vented to move a central block relative to a surrounding frame. All cyclic activity is oscillated at the same frequency. Coordination of phase differences relative to the DSES cycles determines the path of the robotic element which can vector anywhere on a smooth planar surface.
