摘要： An aperture device actuated by a shape memory alloy wire controls two overlapping shuttering surfaces. The two shuttering surfaces control the amount of light transmitted through a lens assembly. The shape memory alloy wire is actuated by a flexible printed circuit which controls a lever slotted to both shuttering surfaces. By Joule heating, the electric current controls the shape of the wire, actuating the aperture device.

摘要： An auto-focus actuator unit including a lens carrier slidably received within a stationary housing frame for a reciprocating motion provided by an actuator is described. The housing frame being carried by a bottom plate provided with an opening, in correspondence with one or more lenses carried by the lens carrier, and with a dust barrier projecting towards the lens carrier and having such a height as to maintain a vertical overlap with the lens carrier over the whole travel of the latter.

摘要： The connection refers to a connecting arrangement with a crimp connector (2) and a wire (3) fixed in place to the crimp connector. The crimp connector encompasses two clamping plates (4, 5) executed as one piece that, in a mounted state, clamp the wire (3) between them and while doing, so fix the wire (3) firmly in place with a force acting in longitudinal axial load direction (B). At least in the mounted state, the inner surfaces of the clamping plates face one another and are at least partially executed as level clamping surfaces (4a, 5a). In the mounted state, the clamping surfaces (4a, 5a) of the clamping plates (4, 5) make contact with one another, whereby an area of the wire section (3′) is pressed partially inside the one clamping plate and partially inside the other clamping plate (4, 5). At least one clamping plate (4, 5) has at least one back gripping surface (8) colliding with its clamping surface (4a, 5a) facing against the load direction (B) and extending transversally to the load direction (B), whereby the clamping surface (4a, 5a) of the other clamping plate (4, 5) extends beyond the back gripping surface (8) against the load direction (B).

摘要： The present invention is inherent to a shape memory alloy actuated fluidic subassembly (10) and to an equipment incorporating it as dispensing device, wherein actuation of the shape memory alloy wires (16, 16′) causes a fluid-tight reservoir (17″) to e compressed by a lid (18) so as to reduce its volume from a maximum volume Vo to a minimum volume V1, this reduction resulting in a pressure increase that causes the opening of an outlet flap (13″) and the dispensing of a fluid through an outlet channel (13).

摘要： The present application relates to a stepwise discrete actuator (10) with two shape memory alloy wires (15, 15′) used in an antagonistic configuration to drive a slider (13) that moves a toothed element (12) through tooth-engaging fingers (131, 132) that are spaced at rest by a distance F that is shorter than the distance T between adjacent teeth by an amount sufficient for a stationary finger lifter (14) to lift that of the slider fingers (131, 132) that does not engage the movable toothed element (12) such that it clears the teeth of the latter.
