Programmed control of athletic training drills

1. A system for training athletes for sports that are played on a play surface, comprising:

a light box;

a support for positioning the light box in relation to a play surface;

a controller operatively associated with the light box;

wherein the light box includes a light source, a lens system through which a collimated beam of light from the light source is projected onto the play surface, a joint by which the lens system can be variably articulated, and a driver for articulating the joint in response to a control signal from the controller;

wherein the controller includes a plurality of digitally stored training programs, each training program specifying a different sequence of control signals to the driver for defining a respective three-dimensional articulation pattern for the lens system, and an input device by which a trainer selects a particular training program;

whereby the controller articulates the lens system such that the projected beam of light includes a spot visible on the play surface and that moves along the play surface at a variable speed and variable direction as specified by the selected training program; and

wherein the input device includes a user-responsive selection screen configured to program the controller to execute any one of a plurality of drills, each drill defining multiple characteristics including a start spot on the play surface, a particular pattern for the spot to trace on the play surface from the start spot, a speed at which the spot traces the pattern, a number of cycles that the pattern will be traced, and a delay interval between the start of each cycle.

2. The system of claim 1 , wherein the drill characteristics include at least two patterns that start from the same start spot; and whether the at least two patterns are executed sequentially, alternatively or randomly.

3. A system for training athletes for sports that are played on a play surface, comprising:

a light box;

a support for positioning the light box in relation to a play surface;

a controller operatively associated with the light box;

wherein the light box includes a light source, a lens system through which a collimated beam of light from the light source is projected onto the play surface, a joint by which the lens system can be variably articulated, and a driver for articulating the joint in response to a control signal from the controller;

wherein the controller includes a plurality of digitally stored training programs, each training program specifying a different sequence of control signals to the driver for defining a respective three-dimensional articulation pattern for the lens system, and an input device by which a trainer selects a particular training program;

whereby the controller articulates the lens system such that the projected beam of light includes a spot visible on the play surface and that moves along the play surface at a variable speed and variable direction as specified by the selected training program; and

wherein the controller comprises a trainer input module for creating a custom training program that defines a desired time-dependent articulation pattern, and a digital processor, a manually operated lens system manipulator, a lens position sensor, and a position generator for delivering a position input signal to the controller commensurate with the manipulated driven position of the lens system, whereby in a pattern learning mode of operation the processor converts the manually driven pattern into a digitally stored custom training program.

4. A method for training athletes for sports that are played on a play surface, comprising:

positioning a light source in relation to a play surface;

projecting a collimated beam of light from the light source to form an illuminated spot on the play surface;

positioning an athlete adjacent to the illuminated spot;

moving the beam commensurate with logic stored in a training pattern database, whereby the illuminated spot moves to follow a predetermined training pattern on the play surface;

prompting the athlete to move on the play surface in a movement pattern corresponding to the training pattern of the spot on the play surface;

positioning another light source in relation to said play surface;

projecting a collimated beam of light from the other light source to form another illuminated spot on the play surface;

positioning another athlete adjacent to the other illuminated spot;

controlling the other light source with logic stored in the training pattern database, whereby the other illuminated spot follows another predetermined training pattern on the play surface; and

prompting the other athlete to move on the play surface in another movement pattern corresponding to the training pattern of the other spot on the play surface;

whereby the athletes simultaneously follow coordinated movement patterns on the play surface.

5. A method for basketball defensive training of at least one player, comprising:

positioning a laser system for articulated movement to project a spot of light on a basketball court, the court having spaced apart parallel sidelines, at least one base line that intersects the sidelines, and a basket midway along the baseline;

providing stored instructions and data accessible by a coach on an interface controller that is in functional communication with the laser system, for selecting a training drill from a plurality of training drills that causes the spot of light to follow a selected one of a plurality of predetermined opponent movement patterns corresponding to the selected drill;

projecting the spot of light at a starting location on the court adjacent the at least one player and spaced from the sideline and the baseline and moving the spot in a curved path toward the basket, that simulates the speed and path of movement of an offensive opponent dribbling a ball toward the basket; and

whereby the at least one player is prompted to follow the spot to maintain defensive positioning relative to the spot.

6. The method of claim 5 , for training a plurality of players, including:

the spot of light at the starting location prompting the plurality of players to align behind the spot;

prompting a first of the aligned players to move on the court in a first movement pattern corresponding to a first training pattern of the spot on the court;

after the first player has completed the first movement pattern, prompting a second of the aligned players to move on the court in a second movement pattern corresponding to a second training pattern of the spot on the court; and

repeating the prompting until all players have been prompted to follow respective movement patterns to maintain defensive positioning relative to the spot.

7. The method of claim 5 , wherein the spot increases in speed as it follows the trace.

8. The method of claim 5 , wherein through the interface controller, the coach also selects two patterns that start from the same start spot; such that one pattern curves toward the basket along the baseline and the other pattern curves toward the basket away from the baseline; and whether the two patterns are executed alternatively or randomly.
