    • An improved buoyancy compensator for providing buoyancy to a Scuba diver. The compensator comprises a vest including a compartment for holding a gas, which compartment is connected by means of an inflation tube, through a control valve and a regulating valve, to a gas supply, so that opening of the control valve allows gas to flow from the gas supply through the tube into the compartment. The compensator is further provided with a gas release valve which allows gas to leave the compartment to a surrounding environment. The compensator is provided with a trigger activated, remote control to open and close the gas release valve.
    • 一种用于向潜水员提供浮力的改进的浮力补偿器。 补偿器包括背心,其包括用于保持气体的隔室,该隔室通过充气管通过控制阀和调节阀连接到气体供应器,使得控制阀的打开允许气体从 气体通过管道进入隔室。 补偿器还设置有气体释放阀,其允许气体离开隔室到周围环境。 补偿器配有触发器,遥控器用于打开和关闭气体释放阀。

    • The present invention is directed toward a restraint system for an infant support such as a highchair. The restraint system includes a restraining member adapted to pass through an aperture formed into the infant support. The restraining member includes a stop member selectively operable to pass through the aperture. Specifically, the stop member is configured to pass through the aperture when in a first orientation relative to the slot, but cannot pass through aperture when positioned in a second (e.g., opposite) orientation relative to the slot. With this configuration, the unintended separation of the restraint system from the infant support may be prevented. Additionally, with this configuration, the accidental tightening of the shoulder straps on a restrained child by a sibling pulling on the straps from behind the seat is also prevented.
    • 本发明涉及一种用于婴儿支架(例如高脚椅)的约束系统。 约束系统包括适于穿过形成婴儿支架的孔的约束构件。 限制构件包括可选择性地操作以穿过孔的止动构件。 具体地,止挡构件被构造成当相对于狭槽处于第一取向时通过孔,但是当相对于槽相对于第二(例如相反)的方向定位时不能通过孔。 通过这种构造,可以防止约束系统与婴儿支架的意外分离。 另外,通过这样的结构,也可以防止肩带上的肩带上的肩带上的肩带上的肩带的意外紧固。
