System and methods for positioning a manipulator arm by clutching within a null-perpendicular space concurrent with null-space movement
ActiveUS9415510B2Additional movementHighly configurableProgramme-controlled manipulatorSurgical robotsEngineeringActuator
Devices, systems, and methods for positioning an end effector or remote center of a manipulator arm by floating a first set of joints within a null-perpendicular joint velocity sub-space and providing a desired state or movement of a proximal portion of a manipulator arm concurrent with end effector positioning by driving a second set of joints within a null-space orthogonal to the null-perpendicular space. Methods include floating a first set of joints within a null-perpendicular space to allow manual positioning of one or both of a remote center or end effector position within a work space and driving a second set of joints according to an auxiliary movement calculated within a null-space according to a desired state or movement of the manipulator arm during the floating of the joints. Various configurations for devices and systems utilizing such methods are provided herein.

Micro-flexure suspension including piezoelectric elements for secondary actuation
InactiveUS7046486B1Reduce the total massSmall sizeRecord information storageFluid-dynamic spacing of headsElectricityActuator
A micro-flexure is provided for achieving secondary actuation in an actuator of a disk drive. The micro-flexure is a separate element which attaches to a standard flexure. A slider mounts to the micro-flexure. Piezoelectric elements attach to the micro-flexure to provide the motive force for displacing the micro-flexure during secondary actuation. The secondary actuation is thereby achieved by isolating movement at the slider.

An actuator for miniature cameras and the like is disclosed. The actuator can comprise a plurality of magnets and a plurality of coils disposed generally symmetrically with respect to the magnets. The magnets and the coils are configured so that they cooperate in order to effect substantially linear movement due to a Lorentz force therebetween. In this manner, undesirable rotational forces can be substantially mitigated. The actuator can be used to effect movement of optical elements to facilitate variable focus, zoom, and / or image stabilization, for example.

High speed scanning or steering device
InactiveUS20050030604A1Maximizing commonalityPrevent undesirable bending forcePicture framesDomestic mirrorsCouplingResonance
A high speed, high displacement steering device used for rapid mirror or light source pointing consisting of a pivoting central element and mounting stem, two orthogonally arranged and offset “V” shaped flexure elements connected to two orthogonally arranged moving elements which are driven by electromotive actuators. Said moving elements are connected to a base structure via parallel motion flexures which serve to prevent undesirable bending forces in the linear actuators, while at the same time preventing undesirable translation movements, cross coupling of motion and resonances. A third type of orthogonal rod flexure restrains the remaining axis of translation motion, namely a translation of the central pivoting element in a direction perpendicular to the tilting axes. Piezoelectric, electrostrictive or similar actuators operate either separately or simultaneously to drive the central element in the only two remaining unrestrained tilting axes, via the offset “V” shaped flexures, producing tilt in any commanded direction. A sealing cover containing an elastic diaphragm to accommodate tilt may be added to the outer support structure as required for protection in harsh environments.
