    • A controllable buoyant system (10) includes a support structure having a sealed hollow enclosure (12) containing a first gas and surrounded by a second gas, either the first gas or the second gas being lighter than ambient air. The hollow enclosure is pre-filled with the first gas via a one-way valve that prevents the first gas escaping and an altitude sensor (14) generates an altitude signal indicative of a height of the support structure. A height transducer (17, 21, 61, 66, 67, 68) coupled to the hollow enclosure is responsive to the altitude signal for varying the buoyancy of the support structure. A controller (15) is coupled to the altitude sensor and to the height transducer and is responsive to the altitude signal and to at least one reference altitude signal for automatically controlling the height transducer in order to maintain the support structure buoyant at the preset altitude.
    • 可控制的浮力系统(10)包括具有密封的中空外壳(12)的支撑结构,所述中空外壳包含第一气体并被第二气体包围,所述第一气体或所述第二气体比环境空气轻。 中空外壳通过单向阀预先填充第一气体,该单向阀防止第一气体逸出,并且高度传感器(14)产生指示支撑结构的高度的高度信号。 耦合到中空外壳的高度传感器(17,21,61,66,67,68)响应于高度信号来改变支撑结构的浮力。 控制器(15)联接到高度传感器和高度传感器,并响应于高度信号和至少一个参考高度信号,用于自动控制高度传感器,以便将支撑结构保持在预设高度。

    • A balloon toy includes a helium-filled balloon; a balloon string tethered to the balloon; and a balloon raising and lowering assembly including: a housing including a handle; a balloon string reel rotatably carried within the housing and carrying the balloon string; an electric motor carried within the housing; a power source carried within the housing for powering the electric motor; a gear assembly including a plurality of gears carried with the housing and operable coupling the electric motor to the balloon string reel for driving rotation of the balloon string reel; a biasing member including a biasing force that urges the gear assembly together so that the plurality of gears are engaged for driving rotation of the balloon string reel for drawing in the balloon string and helium-field balloon and allows the plurality of gears to slip relative to each other if tension on the balloon string is too high.
