    • The optical switch of the present invention advantageously comprises a three dimensional architecture capable of taking input optical signals launched in a first direction, deflecting the signals in a second direction and again in a third direction, preferably orthogonal to the first direction, with no moving parts. The signals are collected at an elevated level without passing through additional nodes. Preferably, incoming beams migrating in an x-direction along a bottom layer are steered in a z-direction to an elevated layer comprising sloped stepped mirror surfaces or a parabolic mirror surface. In an alternate embodiment, a wave guide based optical switch advantageously steers input optical signals from a bottom wave guide layer to an elevated wave guide layer via vertical coupling. The beams are then merged into a collection channel and directly coupled into output fibers without passing through additional transition or cross nodes. In another alternate embodiment, an optical switch include two identical functional plates comprising an array of identically sized and shaped transmissive blocks with stationary inclined electro-optic reflective surfaces.
    • 本发明的光开关有利地包括三维架构,其能够获取在第一方向上发射的输入光信号,使信号沿第二方向和第三方向再次偏转,优选地与第一方向正交,没有移动部分 。 信号在升高的级别收集,而不通过附加节点。 优选地,沿着底层沿x方向迁移的入射光束在z方向上转向包括倾斜的台阶镜面或抛物面镜面的升高层。 在替代实施例中,基于波导的光学开关有利地通过垂直耦合将输入光信号从底部波导层引导到升高的波导层。 然后将光束合并到收集通道中,并直接耦合到输出光纤中,而不通过附加的转换或交叉节点。 在另一替代实施例中,光开关包括两个相同的功能板,其包括具有固定倾斜电光反射表面的相同尺寸和形状的透射块阵列。

    • The invention discloses an all-plastic spray device, comprising a handle, an environmentally friendly cross-arm plastic spring, a positioning seat, a nozzle mechanism, a hexagonal plug, a piston mechanism, an environmentally friendly plastic upper spring, an environmentally friendly plastic lower spring, a plastic ball, and a pump body. The invention adopts the design of two-stage elastic element. Both the environmentally friendly plastic upper spring and the environmentally friendly plastic lower spring are made of plastic materials, which can well replace the metal spring. The two-stage elastic element also has a significant improvement in the pressing feel. In addition to being suitable for conventional liquid use, it is also very suitable for the use of solutions that are prone to corrosion with metal parts. The invention greatly facilitates people's daily use and maintains life, health and safety in people's daily use.

    • An antenna structure is disposed on a substrate. The antenna structure includes a -shaped radiation body and a first radiation body, and both share a feeding end and a grounding end. The feeding end and the grounding end are disposed to a side edge of the -shaped radiation body. The positions of the feeding end and the grounding end allow the -shaped radiation body to form the operation of two frequency bands. Moreover, the first radiation body is vertically extended from the side edge near the feeding end disposed to the -shaped radiation body, and continuously extended from an end to keep a spacing between periphery of the -shaped radiation body and the first radiation body, and extended to a front of an opening of the -shaped radiation body, thereby vertically extending toward the opening. Therefore, the first radiation body could provide the operation of another frequency band.
    • 天线结构设置在基板上。 天线结构包括一个形状的辐射体和一个第一辐射体,并且共用一个馈电端和一个接地端。 馈电端和接地端设置在该辐射体的侧边缘。 进给端和接地端的位置允许形状的辐射体形成两个频带的操作。 此外,第一辐射体从设置于形状的辐射体的馈送端附近的侧边缘垂直延伸,并且从一端连续延伸以保持形状的辐射体的周边与第一辐射体之间的间隔,以及 延伸到形状的辐射体的开口的前部,从而朝向开口垂直延伸。 因此,第一辐射体可以提供另一频带的操作。
