摘要： This invention describes a kind of multipurpose waterproof zipper shoe, including shoe sole, upper, optical sensor, controller, power source and control switch. One end of the upper is connected to shoe sole. The upper is equipped with an opening that has a waterproof zipper. The front end of the upper is armed with optical sensor, buzzer, controller, and light, and at one side of the upper, there is power source and control switch. Both the shoe sole and upper are equipped with a waterproof layer, which can attain the goal of water proofing. The cavity of the shoe sole is equipped with a shoe cover so that the shoe can be put into shoe cover in case of dirty road to prevent the shoe from being smudged. The shoe sole is armed with several sheets for magnetic therapy, which can provide continuous magnetic massage for feet to dredge main and collateral channels and address the problem of deficiency in vital energy and blood. This product is equipped with an optical sensor that can sense road conditions, a controller that controls the light, and a buzzer that alerts users.

摘要： Embodiments of the present invention relate to the field of electronic communication, and more particularly, to a printed antenna and a terminal device comprising said printed antenna. Said printed antenna includes a printed circuit board and at least two antenna patterns; said printed circuit board includes at least two copper foil layers; said at least two antenna patterns are formed on different copper foil layers of said printed circuit board respectively, and said at least two antenna patterns are electrically connected to each other. Since said printed antenna includes a plurality of monolayer antenna patterns, said antenna has a stable performance index and less dependent on the parameters of said printed circuit board, such as the thickness, thereby greatly improving the performance and communication quality of the terminal device's antenna.
摘要翻译：本发明的实施例涉及电子通信领域，更具体地，涉及包括所述印刷天线的印刷天线和终端设备。所述印刷天线包括印刷电路板和至少两个天线图案; 所述印刷电路板包括至少两个铜箔层; 所述至少两个天线图案分别形成在所述印刷电路板的不同铜箔层上，并且所述至少两个天线图案彼此电连接。由于所述印刷天线包括多个单层天线图案，因此所述天线具有稳定的性能指标，并且较少依赖于所述印刷电路板的参数，例如厚度，从而大大提高了终端设备天线的性能和通信质量。
