摘要： A training aid for golfers includes and elongated board that serves as a base member and a dowel pin that is inserted in a preselected transversely disposed throughbore formed in the board. A mirror having a longitudinally extending marking stripe applied to it is fixedly secured to the flat top surface of the board. With the training aid positioned between the golfer and the ball, the golfer orients his or her feet relative to the board and dowel pin in a predetermined way, and aligns his or her shoulders, hands, and head with the marking stripe during the set-up. The position of the club may also be observed during a slow motion practice swing, but the mirror is not observed after the set-up if the ball is to be hit with a regular swing. With practice, the golfer acquires a muscle memory of a proper set-up, and a properly executed golf swing. Further structural details include mounting blocks for storing the dowel pin when not in use and a mirror protector that is releasably attachable to the base member in overlying relation to the mirror.

摘要翻译： 用于高尔夫球手的训练辅助装置包括用作基座构件的细长板和插入在板中形成的预选的横向布置的通孔中的定位销。 具有施加到其上的纵向延伸的标记条的反射镜固定地固定到板的平坦顶表面。 训练辅助者位于高尔夫球手和球之间，高尔夫球手以预定的方式相对于棋盘和定位销定位他或她的脚，并在组合中将他或她的肩膀，手和头与标记条对齐， 向上。 在慢速运动练习摆动时也可以观察球杆的位置，但是如果球以正常摆动击球，则在安装后不会观察到镜子。 实践中，高尔夫球手获得正确设置的肌肉记忆和正确执行的高尔夫挥杆。 另外的结构细节包括用于在不使用时存储定位销的安装块和可以以与镜子重叠的方式可释放地附接到基座构件的镜保护器。

摘要： A miniature microstrip dipole antenna is constructed on a high permitivity dielectric substrate for compactibility with microwave monolithic integrated circuit (MMIC) technology. The antenna comprises two dipole arms coupled to opposite faces of the substrate. The dipole arms are coupled to a microstrip transmission line through a tapered balun. The tapered balun comprises two conductors on opposite faces of the substrate which are coupled to corresponding dipole arms. The conductors are separated laterally (with respect to the width of the face of the substrate) a calculated distance, and are gradually tapered. This allows the balun to efficiently transform unbalanced signals at the microstrip transmission line to balanced signals at the plurality of dipole arms. Alternatively, the balun allows balanced signals at the dipole arms to be efficiently transformed to unbalanced signals at the microstrip transmission line. To achieve additional radiation directivity, a ground plane is coupled to and parallel with a back face of the substrate. By using a high dielectric substrate, the cavity formed between the substrate and the ground plane is relatively very shallow.
