摘要： A golf swing training device is provided herein. A ball is connected to a line wound about a reel, and one or more weights are slidably positioned upon the line. When the ball is struck, its inertia strips line from the reel, and the line trails behind the ball in flight. Simultaneously, the weights are carried along by the line, and these weights exert a downward force on the line, thereby dampening the flight of the struck bail and forcing the ball back toward the ground. Also, when the ball's trajectory curves upward, the friction between the weight and the line increases, thus decelerating the ball. After the ball strikes the ground, the ball can be retrieved by manually rotating the reel in the preferred embodiment.

摘要： A reconfigurable serial loop or ring communication system is provided with a method and apparatus which enables stations on the loop to ascertain the address of its nearest active upstream neighbor (NAUN). A Ring Poll Frame is generated and broadcast from an originating station. The Ring Poll Frame includes a Ring Poll command, a From Address and a reset Address Recognized (AR) control bit. The first active downstream station recognizes the command with the control bit in the reset state, copies the contents of the ring poll frame and sets the bit. The set bit inhibits subsequent downstream stations from copying the frame. The first active station then generates a substantially similar formatted ring poll frame and passes it downstream. The process is continued by downstream active stations until the originating station receives a ring poll frame having a reset control bit. The reset control bit is an indication that all stations on the loop know the address of its NAUN.A ring management station may use the ring poll process to acquire information relative to the location of active stations on the ring.
摘要翻译：可重新配置的串行环路或环通信系统被提供有使得环路上的站可以确定其最近的主动上行邻居（NAUN）的地址的方法和装置。生成环形轮询帧并从始发站广播。环形轮询帧包括环形轮询命令，起始地址和复位地址识别（AR）控制位。第一个活动下游站识别具有复位状态的控制位的命令，复制环轮询帧的内容并设置该位。设置位禁止后续下游站复制帧。然后，第一活动站产生大致相似的格式化的环形轮询框，并将其传送到下游。该过程由下游主动站继续，直到发起站接收到具有复位控制位的环状轮询帧。复位控制位表示环路上的所有站都知道其NAUN的地址。环形管理站可以使用环形轮询过程来获取关于环上的活动站的位置的信息。
