    • A rotating seat for suspension from a play set structure includes a seat body rotatable about a generally vertical axis with an upper seating surface configured to support a user, an elongated suspending element configured to support the seat body from the play set structure, and a handle assembly operably coupled with the suspending element to cause rotation of the seat body relative to the axis upon actuation by the user. The suspending element extends substantially vertically, presents opposite upper and lower end margins, is configured to operably couple with the play set structure along the upper end margin, and is operably coupled with the seat body at a location spaced from the upper end margin. A damped pivot connection assembly configured to operably secure the suspending element with the play set structure and allow restrained pivoting movement of the suspending element relative to a fixed bracket of the connection assembly is also disclosed.
    • 用于从玩具组合悬挂的旋转座椅包括可围绕大体上垂直的轴线旋转的座椅本体,具有构造成支撑使用者的上座面,被配置为从座椅组件支撑座椅本体的细长悬挂元件和手柄 组件与悬挂元件可操作地联接,以在使用者致动时引起座椅主体相对于轴线的旋转。 悬挂元件基本垂直地延伸,呈现出相对的上端边缘和下端边缘,构造成沿着上端边缘可操作地与游乐设备结构连接,并且在与上端边缘间隔开的位置处可操作地联接座椅主体。 阻尼枢轴连接组件,其被配置为可操作地使悬挂元件与游戏组合结构固定并且允许悬挂元件相对于连接组件的固定支架的约束的枢转运动。

    • A shape memory alloy (SMA) actuator for engaging and actuating a device. The actuator includes an engagement mechanism, a bias element, and a SMA object(s). The SMA actuator may automatically and passively transfer to a backup or redundant feature that resets or extends the actuator's operational life. In one embodiment, the SMA actuator includes an additional SMA object(s) that replaces the primary SMA object(s) in the event the primary SMA object(s) breaks. The SMA actuator may also be configured to apply a dynamic stress to the SMA object during transition of the object to modify the transition temperatures of the object. The SMA actuator may be part of a fluid distribution system, such as a heating, ventilation, and air conditioning (HVAC) system and used to control the flow of fluid, such as air, from the distribution system.
    • 用于接合和致动设备的形状记忆合金(SMA)致动器。 致动器包括接合机构,偏置元件和SMA物体。 SMA执行器可以自动和被动地传送到复位或延长执行器的使用寿命的备用或冗余功能。 在一个实施例中,SMA致动器包括在主SMA对象断开的情况下替代主SMA对象的附加SMA对象。 SMA致动器还可以被配置为在对象的转变期间向SMA对象施加动态应力以修改对象的转变温度。 SMA致动器可以是流体分配系统的一部分,例如加热,通风和空调(HVAC)系统,并且用于从分配系统控制诸如空气的流体的流动。
