摘要： A shape memory alloy actuation apparatus comprises a support structure (2) and a movable element (10). A helical bearing arrangement (20) supporting the movable element on the support structure guides helical movement of the movable element with respect to the support structure around a helical axis (H). At least one shape memory alloy actuator wire (60) is connected between the support structure and the movable element in, or at an acute angle to, a plane normal to the helical axis, so as to drive rotation of the movable element around the helical axis which the helical bearing arrangement converts into said helical movement.

摘要： Broadly speaking, the present techniques provide specific arrangements of shape memory alloy (SMA) actuator wires in SMA actuation apparatuses. In one arrangement, a single straight shape memory alloy actuator wire may be used, which may be inclined at an acute angle greater than 0 degrees with respect to a plane normal to the movement direction. In another arrangement, two straight lengths of shape memory alloy actuator wire may be used, where the SMA wires may be inclined at an acute angle greater than 0 degrees with respect to a plane normal to the movement direction.

摘要： Broadly speaking, embodiments of the present techniques provide an actuator that comprises segments of shape memory alloy (SMA) actuator wire that can be used to deliver a relatively large output stroke. In particular, two segments of SMA actuator wire may be mechanically coupled together around a corner of a static component of the actuator such that a displacement (e.g. contraction) of one segment causes a displacement (e.g. contraction) of the other segment. In this way, the displacement of each segment combines in an additive manner to generate a large output stroke that is able to move a moveable component of the actuator.

摘要： A pump includes a pumping arrangement comprising a movable element arranged to pump a fluid and shape memory alloy wires coupled to the movable element for moving the movable element. The resistance of at least one of said one or more shape memory alloy wires is measured. A control system supplies drive signals to the shape memory alloy wires and monitors the measured resistance for verifying the operation of the pumping arrangement. The control system detects abnormal operation of the pumping arrangement on the basis of the measured resistance and detects abnormal resistance to movement of the movable element.

摘要： A device for depth mapping of an object comprises an emitter comprising a laser and an optical component, an actuator and a control processor unit. The actuator is arranged to change the relative position and/or relative orientation of the optical component to the laser. The control processor unit is configured to receive information relating to change in the location and/or orientation of the device during use of the device, and to instruct the actuator to change the relative position and/or relative orientation of the optical component to the laser so as to compensate for change in the location and/or orientation of the device during use of the device.

摘要： An SMA actuator arrangement is assembled using a strut element shaped to comprise a sacrificial strut body and crimp tabs held apart by the sacrificial strut body. A SMA wire is laid across the crimp tabs which are folded and pressed to form crimps holding the SMA wire. The crimps are then attached to static and moving parts, after which the sacrificial strut body is removed. The method allows the crimping to be performed without hindrance from the static and moving parts, the sacrificial strut body holding the relative locations of the crimps prior to attachment.

摘要： Suspension System for a Camera Lens Element A camera lens elementis suspended on a support structure by balls that allow movement of the camera lens elementorthogonal to the optical axis and plural flexures connected between the support structure and the camera lens elementto bias them against the balls whilst permitting said movement of the camera lens elementorthogonal to the optical axis. Lateral movement is driven by a lateral actuation arrangement comprising plural SMA actuator wires.The flexures provide a lateral biasing force that biases the camera lens elementtowards a central position.An electrical connection is made through the flexures from the support structure to the camera lens element. The flexures may be connected to laminated structures. Fig.
