Abstract

The method and apparatus for improving the performance of a batter. The apparatus includes sequencing lights (38) which are representative of a ball moving toward an impact zone. Further included are light indicia (46 and 48) which inform a batter that the pitched ball will either be a ball or a strike so that the batter may determine whether or not he should swing the bat. Also included are means to generate an electrical signal to indicate that the strike light (46) is illuminated. First and second light beams (18 and 20) are provided which pass through the ball/bat impact zone and are located at selected and known distances apart such that the bat swing through the impact zone will sequentially interrupt both first and second beams (20 and 18). First and second sensors (22 and 24) are also located for receiving and sensing the presence of the first and second beams and provide second and third electrical signals, respectively, if the beams are interrupted. Circuitry is included for measuring and displaying both a first elapse time (corresponding to batter response) between the occurrence of the first and second electrical signals and also a second elapse time (relative to bat velocity) between the second and third electrical signals.

Claims

1. Apparatus for improving the performance of a batter by monitoring the response time of the batter and the velocity of a bat as it moves through a selected ball/bat impact zone comprising:

sequencing means to provide a sequencing light having first indicia representative of a ball moving towards said impact zone, and second indicia which appears subsequent to said first indicia to inform said batter whether said ball will pass through said ball/bat impact zone, and means to generate a first electrical signal at the appearance of said second indicia when said second indicia indicates said ball will pass through said ball/bat impact zone;

first and second means for providing first and second beams of light respectively which pass through said ball/bat impact zone, said first and second means being located such that said beams of light are at a selected and known distance apart and such that a bat swing through said impact zone sequentially interrupts both of said first and second beams;

first and second sensor means for receiving and sensing the presence of said first and second beams respectively thereon, and for providing second and third electrical signals representative of the interruption of said first and second beams;

circuitry for measuring a first elapse time between the occurence of said first and second electrical signals, said first elapse time corresponding to said response time of said batter, and for measuring a second elapse time between said second and third electrical signals, said second elapse time being relatable to said velocity of said bat as it moves through said ball/bat impact zone; and

means for displaying said first and second elapse time as a measure of said performance of said batter.

2. The apparatus of claim 1 wherein said first and second beams are laser beams.

3. The apparatus of claim 1 wherein said first and second beams of light are oriented to be substantially perpendicular with the earth'"'"'s surface.

4. The apparatus of claim 1 wherein said first elapse time representation is displayed in seconds and said second elapse time determines the display of velocity.

5. The apparatus of claims 1, 2, 3, or 4 wherein said first indicia of said sequencing means includes a multiplicity of vertically positioned lights which are illuminated sequentially from a topmost light to a bottommost light to represent the forward travel of a pitched ball, and said second indicia of said sequencing means includes a strike indicator light informing said batter that said ball is a strike in said impact zone and he should swing, and a ball indicator light informing said batter said ball is not in said impact zone and not to swing, and further comprises random control means for randomly determining whether the strike or ball indicator light should illuminate after said sequential illumination of said multiplicity of vertically positioned lights.

6. The apparatus of claims 1, 2, 3, or 4 wherein said first indicia includes a multiplicity of horizontally positioned lights extending from a simulated pitcher'"'"'s mound toward said batter, said multiplicity of lights are illuminated sequentially from a farthest light to a closest light to represent the forward travel of a pitched ball, and said second indicia includes a strike indicator light informing said batter that said ball is a strike and he should swing, and a ball indicator light informing said batter that said ball is not in said impact area and that he should not swing, and further comprises random control means for randomly determining whether said strike or ball indicator light should illuminate after sequential illumination of said horizontally positioned lights.

7. The apparatus of claims 1, 2, 3, or 4 further comprising:

a curtain including a multiplicity of vertical, parallel light beams and corresponding light detectors, each of said multiplicity of light beams being positioned a selected distance from an adjacent one of said multiplicity of light beams, said curtain of light beams being positioned to extend across sad ball/bat impact zone between said first and second light beams such that as said bat is swung through said curtain, said bat interrupts only a portion of the multiplicity of light beams; and

circuit means connected to said light detectors, including display means, whereby the position of the end portion of said bat being swung through said curtain can be determined by determining which light beams of said curtain were interrupted.

8. The apparatus of claim 7 wherein said second elapse time determines a velocity that is displayed, and further including compensating means for providing an adjusting signal to said means for displaying velocity such that said velocity represents the speed of said end portion of said bat.

9. A method for improving the performance of a batter'"'"'s response time and for determining the velocity of a bat as it is swung by the batter through a selected ball/bat impact zone comprising the steps of:

sequencing the illumination of a multiplicity of lights to provide visible indicia representative of a ball moving towards said impact zone;

randomly illuminating one of two indicator lights after said illuminating step of said multiplicity of lights to instruct said batter to swing or not to swing and generating a first electrical signal upon illumination of said indicator light instructing said batter to swing;

providing first and second beams of light which pass through said ball/bat impact zone, said first and second beams of light being located at selected and known distances apart and such that a bat swung through said impact zone will sequentially interrupt said beams of light;

sensing the presence of said first and second beams of light thereon and providing second and third electrical signals representative of the interruption of said first and second beams of light;

determining a first elapse time between the occurrence of said first and second electrical signals corresponding to said batter'"'"'s response times, and a second elapse time between said second and third electrical signals relatable to said velocity of said bat through said impact zone; and

displaying said first and second elapse time to indicate said performance of said batter.
