Abstract

A method and device for detecting improperly inflated game balls during a football game is disclosed. During a stoppage in play, a referee strikes the ball with an impulse of arbitrary value using a data generating impact module containing at least one sensor. Data correlative to the impulse is processed to determine the pressure of the ball. Information sufficient to verify whether the pressure of the game ball is within a prescribed range pursuant to the rules of football is communicated to an output. A designated official determines whether the football is properly inflated.

Claims

1. A method for detecting an under-inflated game ball during a football game, the method comprising the steps of:

a) striking the game ball with an impulse of arbitrary value using a data generating impact module, the data generating impact module containing at least one sensor;

b) the at least one sensor generating data correlative to the impulse of arbitrary value imparted to the ball and causing the data to be transmitted to a data processing module;

d) the data processing module receiving the data from the data gathering module, processing the data to determine the pressure of the ball and communicating information about the determined pressure of the ball to a pressure output, the information being sufficient to verify whether the pressure of the game ball is within a prescribed range;

e) the pressure output receiving the information about the determined pressure of the ball and outputting information sufficient to verify whether the pressure of the game ball is within the prescribed range; and

f) sensing the information sufficient to verify whether the pressure of the game ball is within the prescribed range.

2. The method of claim 1 wherein the at least one sensor comprises at least one of an acceleration sensor, a force sensor and a contact sensor.

3. The method of claim 2 wherein the data processing module is configured to process the data to determine a value correlative to at least one of a peak force and an impulse duration and to use the value correlative to at least one of the peak force and the impulse duration to determine the pressure of the ball.

4. The method of claim 3 wherein the game ball has laces, further comprising the steps of placing the game ball longitudinally on the ground and orienting its laces to be substantially horizontal, thereby defining a contact region on the ball where it rests on the ground, and striking the game ball at a position located substantially opposite the contact region with an impulse of arbitrary value.

5. The method of claim 1 wherein the at least one sensor comprises at least one of an acceleration sensor, a force sensor and a contact sensor.

6. A pressure measuring device comprising:

a data generating impact module constructed and arranged for striking a pneumatically inflated object with an impulse of arbitrary value, generating data correlative to the impulse of arbitrary value imparted to the pneumatically inflated object and transmitting the data to a data gathering module;

the data generating impact module further being constructed and arranged to receive at least one sensor;

the data gathering module being constructed and arranged to receive the data from the at least one sensor and communicate the data to a data processing module;

the data processing module being constructed and arranged to receive the data from the data gathering module, process the data to determine the pressure of the pneumatically inflated object and communicate the determined pressure of the pneumatically inflated object to a pressure output; and

the pressure output being constructed and arranged to receive the determined pressure of the pneumatically inflated object and output the determined pressure of the pneumatically inflated object.

7. The pressure measuring device of claim 6, wherein the at least one sensor comprises at least one of an acceleration sensor, a force sensor and a contact sensor.

8. The pressure measuring device of claim 6, wherein the data generating impact module comprises an instrumented hammer.

11. The pressure measuring device of claim 6, wherein the data processing module is in wired communication with the data generating impact module.

12. The pressure measuring device of claim 6, wherein the data processing module is in wireless communication with the data generating impact module.

13. The pressure measuring device of claim 6, wherein the pressure output comprises an audible sound.

14. The pressure measuring device of claim 6, wherein the pressure output comprises a visual readout.

15. The pressure measuring device of claim 14, wherein the visual readout comprises at least one of an LCD, an LED, an analog gauge, and a digital readout.

16. The pressure measuring device of claim 6 wherein the pneumatically inflated object is a ball.

17. The pressure measuring device of claim 16 wherein the ball is a football.

18. The pressure measuring device of claim 8 wherein the instrumented hammer further comprises a head configured to receive the at least one sensor and having a striking face constructed and arranged to impart the impulse of arbitrary value to the pneumatically inflated object, the at least one sensor positioned within the head, and a handle configured to be held by a human hand and constructed and arranged to impart the impulse of arbitrary value imparted by a human hand from the handle to the head.
