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： SMA actuator wires in an SMA actuation apparatus are connected in tension between a movable element and a support structure, applying forces to the movable element in opposed directions. Measures of the resistances of the SMA actuator wires are detected. A feedback difference measure is derived being the sum of the measures of resistance of the SMA actuator wires, relatively scaled by factors, in respect of the SMA actuator wires, the magnitude of which represents a component along the predetermined axis of a force applied by the SMA actuator wire and the sign of which represents a direction along the predetermined axis. The ratio has opposite signs for respective ones of said opposed directions. The powers of drive signals supplied to the SMA actuator wires are controlled in response to the feedback difference measure to reduce the difference between the feedback difference measure and a target difference measure.
