Abstract:
1. An apparatus to aid a basketball player to keep his shooting forearm parallel to a vertical centerline of said basketball player body during a shooting motion, said apparatus comprising: a sleeve to be worn on a forearm of said basketball player; an electrical circuit attached to said sleeve; a visual indicator coupled to said electrical circuit; and a positioning sensor for detecting relative orientation of a longitudinal axis of the sleeve in relation to gravity, having an indicating signal output electronically coupled to said electrical circuit which varies to indicate varying degrees of inclination from vertical; such that the electrical circuit receives an indication of the orientation of the longitudinal axis of the sleeve relative to gravity from the indicating signal output of the positioning sensor and causes the visual indicator to output a variable visual signal perceptible by the player indicating the relative position of said basketball player's forearm position to a vertical position.
