    • A dielectric-based nonlinear transmission line (NLTL) coupled to an adjacent waveguide. Energy in an input pulse to the nonlinear transmission line is concentrated into an electromagnetic shock or a series of soliton-like oscillations by the nonlinear properties of the NLTL. Energy from the electromagnetic shock or the soliton-like oscillations are transferred into the waveguide. A plate of the NLTL coupled to the waveguide can include an aperture or a series of apertures. Energy from the electromagnetic shock or the soliton-like oscillations can then be transferred into waveguide via an aperture or apertures in such a way that forward and/or backward guided electromagnetic waves are generated in the waveguide. The waveguide can contain at a nonlinear magnetic material, a dielectric material, a slow wave structure, or a metamaterial. The NLTL can include nonlinear dielectric elements such as a periodic array interspersed with linear dielectric elements.
    • 耦合到相邻波导的基于介质的非线性传输线(NLTL)。 通过NLTL的非线性特性,对非线性传输线的输入脉冲中的能量集中在电磁冲击或一系列孤子振荡中。 来自电磁冲击或孤子状振荡的能量被转移到波导中。 耦合到波导的NLTL的板可以包括孔或一系列孔。 然后可以通过孔或孔将来自电磁冲击或孤子状振荡的能量转移到波导中,使得在波导中产生正向和/或反向引导的电磁波。 波导可以包含非线性磁性材料,电介质材料,慢波结构或超材料。 NLTL可以包括非线性介电元件,例如散布有线性介电元件的周期阵列。

    • Apparatus for securing or retaining a heatsink. The heatsink retention apparatus includes a heatsink module that cooperates with first and second spring loaded latches secure to a circuit board on opposing sides of a heat-generating component. The heatsink module includes a handle pivotally secured to opposing sides of the heatsink body, and bails pivotally secured to the handle. In addition, the bails extend downward to dispose a lower bail member adjacent the spring loaded latches. As the handle pivots between a first position to raise the bails and a second position to lower the bails, the bails automatically move from a locked position to an unlocked position. Each of the spring loaded latches include a hook and at least one pre-loaded spring to transfer a minimum downforce to the lower bail members when the bails are raised. Accordingly, embodiments may be operated from the top of the heatsink without the use of tools, while providing a desired downforce over a range of heatsink heights.
    • 用于固定或保持散热器的装置。 散热器保持装置包括散热模块,该散热器模块与在发热部件的相对侧上固定到电路板的第一和第二弹簧加载闩锁配合。 散热器模块包括可枢转地固定到散热器主体的相对侧的手柄,以及枢转地固定到手柄的导轨。 此外,吊环向下延伸以配置邻近弹簧加载的闩锁的下部吊环构件。 当手柄在第一位置上升起腿部和第二个位置以降低皮条之间时,该皮带自动地从锁定位置移动到解锁位置。 每个弹簧加载的闩锁包括钩子和至少一个预加载的弹簧,用于当提升绳索时将最小的下压力传递到下部吊钩构件。 因此,实施例可以在不使用工具的情况下从散热器的顶部操作,同时在一定范围的散热器高度上提供期望的下压力。
