    • Embodiments of the subject invention relate to a method and apparatus for stabilizing a moveable element of a device. In an embodiment, a device is provided including a base, an element capable of moving relative to the base, and at least one actuator. Each actuator of the at least one actuator is configured such that when the actuator is driven the actuator moves into a hold position, wherein the actuator limits movement of the element. In a particular embodiment, the at least one actuator holds the element, or a portion of the element, at a particular position, angle, and/or attitude. In an embodiment, the at least one actuator is used to limit movement of the element when the device is turned off. The at least one actuator can be positioned to allow greater movement of the element when the device is turned on.
    • 本发明的实施例涉及一种用于稳定装置的可移动元件的方法和装置。 在一个实施例中,提供了一种装置,其包括底座,能够相对于底座移动的元件和至少一个致动器。 至少一个致动器的每个致动器构造成使得当致动器被驱动时,致动器进入保持位置,其中致动器限制元件的移动。 在特定实施例中,至少一个致动器将元件或元件的一部分保持在特定位置,角度和/或姿态。 在一个实施例中,当装置关闭时,使用至少一个致动器来限制元件的移动。 所述至少一个致动器可被定位成允许当所述装置打开时元件的更大移动。

    • A curved multimorph actuator is provided composed of a plurality of materials, each material exhibiting different deformations in response to a stimulus, such as heat. Application of different stimuli causes the actuator to bend and/or twist. In an embodiment, the actuator is capable of rotating an object about its center without significantly shifting the center in one or more dimensions. In a further embodiment, the actuator can be used to rotate an object about a first axis and a second axis, wherein the first axis and the second axis are mutually perpendicular. In an embodiment, rotation about the first axis and the second axis are achieved in combination. In another embodiment, rotation about the first axis is produced in response to a first stimulus and rotation about the second axis is produced in response to a second stimulus.
    • 提供由多种材料组成的弯曲多压电致动器,每种材料响应于诸如热的刺激而呈现不同的变形。 不同刺激的应用使致动器弯曲和/或扭曲。 在一个实施例中,致动器能够围绕其中心旋转物体,而不会在一个或多个维度上显着地偏移中心。 在另一实施例中,致动器可用于围绕第一轴线和第二轴线旋转物体,其中第一轴线和第二轴线相互垂直。 在一个实施例中,组合地实现围绕第一轴线和第二轴线的旋转。 在另一个实施例中,响应于第一刺激而产生围绕第一轴的旋转,响应于第二刺激而产生围绕第二轴的旋转。
