First Claim
1. An apparatus for programming and controlling the seizing of a hangle of a ball-hitting instrument and the guiding of the instrument by a player during striking of a ball in a ball game, comprising:
- (a) an apparatus casing;
(b) a housing therein for a source of electric direct current;
(c) an electronic circuit mounted in said casing and comprising;
(c.1) a circuit board having a longitudinal axis, a first and a second edge transverse to said axis, and an outer and an inner board face;
(d) on-off-switch means mounted on said casing and for turning direct current from said current source on and off;
(e) perceivable signals-emitting means;
(f) integrated circuit chip means for being programmable for controlling a first time interval (X) of adjustable duration and a second time interval (Y) of fixed duration following directly upon said first time interval;
(g) potentiometer means for adjusting the duration of said first time interval;
(h) a first noiseless quick-response elongated switch, having an inner and an outer contact end and being mounted on, and extending parallel with, said outer board face of said circuit board and forming an angle of about 40°
with said longitudinal board axis, said outer contact end of said first switch being nearer said first transverse board edge than said inner first switch contact end;
(i) a second noiseless quick-response elongated switch, having an inner and an outer switch end and being mounted at said inner switch end on said outer board face, projecting therefrom at a substantially right angle;
(k) a third elongated switch, being mounted on said circuit board and having an outer end and an inner end, said inner end being nearer said first transverse board edge than said outer third switch end; and
(l) a fourth elongated switch having an inner end and an outer end and being mounted on said outer face of said circuit board, said outer end of said fourth switch being nearer said first transverse board edge than said inner fourth switch end.

Abstract
A ball-hitting instrument for playing ball games, comprises a handle and a flat head part (preferably a tennis racket bearing a screen in the head part) and an apparatus for programming and controlling the seizing of the handle and the guiding of the instrument during a player'"'"'s motions for hitting a ball. The apparatus is mounted on the handle and contains an electronic circuit comprising an on-off switch, a perceivable signals-emitting device such as a buzzer, an integrated circuit chip, a potentiometer and four noiseless, quick-response switches each having a travel path and a circuit-making mercury or magnetic body movable back and forth along that path to make or break circuit.

- 23. An apparatus for programming and controlling of the seizing position and the guidance of a ball-hitting instrument, said apparatus comprises an integrated circuit chip means, switching and controlling means for responding to a rhythmic motion sequence of the ball-hitting instrument, means for programming the rhythmic motion sequence of the ball-hitting instrument, means for controlling execution of a program, and means for producing a signal indicating at least one of the correct and incorrect rhythmic motion sequences of the ball-hitting instrument, whereby the complete sequence of motional phases during forehand play, backhand play and service of a ball with the aid of the ball hitting instrument are programmed as well as controlled by comparison with a master program produced with said apparatus, independently of whether the player is right-handed or left-handed.
