    • An adjustable foldable bed frame comprises an outer assembly having a body section and a leg section. Each section has a substantially rectangular periphery with an opening and is pivotally coupled together by a pair of first coupling members for movement between an open configuration whereby the sections are co-planar, and a closed configuration whereby the sections are parallel with each other. An inner assembly having a body component and a leg component are positioned within the opening of the body section and the leg section, respectively. The body component comprises a torso portion which is independently adjustable from a flat configuration to a plurality of reclined configurations. The leg component comprises a calf portion which is independently adjustable from a flat configuration to a plurality of elevated configurations. A connecting bracket assembly fixedly couples adjacent adjustable foldable bed frames such that adjacent torso and calf portions are adjustable together.
    • 可调节的可折叠床架包括具有主体部分和腿部的外部组件。 每个部分具有基本上矩形的周边,具有开口,并且通过一对第一联接构件枢转地联接在一起,用于在打开构造之间移动,由此部分是共面的,以及封闭构造,由此部分彼此平行。 具有主体部件和腿部部件的内部组件分别位于主体部分和腿部部分的开口内。 身体部件包括躯体部分,其可以从平坦构型独立地调节到多个倾斜的构型。 腿部件包括可从平坦构型到多个升高构型独立调节的小腿部分。 连接支架组件将相邻的可调节可折叠床架固定连接,使得相邻的躯干和小腿部分可调节在一起。

    • A technique for dynamically adjusting an output voltage for a welding or cutting operation is provided. The technique allows for varying output voltage at the welding or cutting torch by manipulating the duty cycles of two forward converter circuits. The present disclosure provides methods and systems for increasing synchronized duty cycles in a pair of forward converter circuits in response to increasing output voltage demand then changing a phase shift between the duty cycles in response to further increases in output voltage demand. The present disclosure provides a controller designed to receive input signals and generate output pulse width modulation signals that control the duty cycle width and phase shift of the outputs of the forward converter circuits in response to these signals. Methods of accommodating for the time needed for the transformer core to reset via leading edge or lagging edge compensation are provided.
    • 提供了用于动态调整焊接或切割操作的输出电压的技术。 该技术允许通过操纵两个正激变换器电路的占空比来改变焊接或割炬处的输出电压。 本公开提供了用于响应于增加的输出电压需求来增加一对正激变换器电路中的同步占空比的方法和系统,随后根据输出电压需求的进一步增加来改变占空比之间的相移。 本公开提供了一种控制器,其被设计为接收输入信号并产生输出脉冲宽度调制信号,以响应于这些信号来控制正激变换器电路的输出的占空比宽度和相移。 提供了通过前沿或滞后边缘补偿来满足变压器磁芯复位所需时间的方法。
