Racket orientation indicator device and associated method of operation
First Claim
1. A racket assembly comprising:
- a handle;
a racket head supported by said handle;
a string face strung across said racket head, wherein said string face extends in a common plane;
at least one sensor for detecting when said common plane of said string face deviates from a vertical plane;
an indicator for providing a perceivable indication when said common plane of said string face is detected deviating from said vertical plane.

Abstract
A device and method for determining whether or not the string face of a racket is held in a vertical plane as the racket is swung. At least one sensor is attached to a racket. The sensors detect when the string face of the racket is in a vertical plane and when the string face deviates from that vertical plane. An indicator is also attached to the racket, wherein the indicator produces a perceivable indication to the user of the racket wher activated. A logic circuit is used to connect the sensors to the indicator. When the sensors detect that the string face of the racket has wandered from the vertical plane, the indicator is activated and the player holding the racket is informed of the lapse in form. By repeatedly swinging the racket and trying to avoid activating the indicator, a player can train to have a proper level swing.

12. A method of indicating when the string face of a racket is not being held in a vertical plane, said method comprising the steps of:
-
providing at least one sensor to a racket that detects when the string face of the racket is oriented outside of a vertical plane;
providing an indicator on said racket that is capable of producing a perceivable indication when activated; and
activating said indicator when said sensors detect that the string face of the racket is oriented outside the vertical plane. - View Dependent Claims (13, 14, 15, 16, 17)
