Abstract: A golf training device and method indicates the proper position and/or motion of the golfer's trail wrist during the club downswing. The device may detect that desired DWLA is attained and provide real-time alerts of same. The device may provide positive feedback in the form of an auditory, tactile, visual and/or other signal.

Abstract: A golf training aid is provided that teaches a golfer the proper motion of the lead knee during a backswing by providing the golfer with a positive feedback alert. A motion sensor detects a predetermined optimal position of the lead knee and a positive feedback alert is produced when the predetermined optimal position is achieve. The positive feedback alert may be an audible, visual, and/or tactile alert to notify a user that the predetermined optimal position is achieved.

Abstract: Methods, systems, and apparatuses for ways of testing tags are provided. In an aspect of the present invention, an antenna is mounted in a cavity of a surface. The antenna transmits a test signal, such as a radio frequency (RF) test signal, to the antenna of an adjacent tag, to test the adjacent tag. In aspects, multiple cavities having antennas may be arranged in various ways in the surface, such as in a “checkerboard pattern” (e.g., diagonally positioned from each other), to test multiple tags in a web of tags simultaneously. In another aspect, tags that are not being tested may be held at an electrical voltage, such as a ground voltage, to disable the tags from responding to the test signals of other tags. For example, in an aspect, a vacuum system may be used to hold tags in a web of tags to the surface to hold antennas of the tags at the electrical voltage.
