Abstract

A system determines athletic performance. A pressure sensor senses change in elevation. A microprocessor processes signals from the pressure sensor to determine speed corresponding to the change in elevation. A display reports the speed to a user.

Claims

1. A system comprising:

a data storage device storing athletic performance data obtained from a plurality sensing units, each of the sensing units being configured for attachment to a person and for generating the athletic performance data; and

a server operatively connected to the storage device, wherein the server is configured to provide a comparison of athletic performance between multiple users based on the athletic performance data and access to the comparison via a data network;

wherein the comparison is a quantitative comparison of airtime of a first user at a first geographical location and airtime of a second user at a second geographical location.

2. The system of claim 1, wherein the athletic performance data comprises at least one of speed data, distance data, acceleration data, pace data, power data, energy data, and/or location data.

3. The system of claim 1, wherein the data network is the Internet, a computer network, or a wide area network.

4. The system of claim 1, wherein the athletic performance data is generated at different geographic locations.

5. The system of claim 1, wherein the comparison is used to determine a winner of an athletic competition.

6. The system of claim 1, wherein the athletic performance data is tagged to particular users.

7. The system of claim 6, wherein tagging associates a code identifying a particular user or one of the sensing units.

8. The system of claim 7, wherein the server is configured to receive a request specifying a tag of the particular user or the one of the sensing units and provide athletic performance data associated with the tag.

9. The system of claim 1, wherein the server is a web site server.

10. The system of claim 1, wherein the comparison comprises a quantitative comparison of speed and/or distance of a first user at a first geographical location and speed and/or distance of a second user at a second geographical location.

11. The system of claim 1, wherein the comparison comprises a quantitative comparison of distance traveled by a first user at a first geographical location and distance traveled by a second user at a second geographical location.

12. The system of claim 1, wherein the comparison comprises a quantitative comparison of power of a first user at a first geographical location and power of a second user at a second geographical location.

13. A method comprising:

accessing, by a server, athletic performance data stored by a data storage device, wherein the athletic performance data is obtained from a plurality sensing units, each of the sensing units being configured for attachment to a person and for measuring the athletic performance data; and

providing a quantitative comparison of airtime of a first user at a first geographical location and airtime of a second user at a second geographical location.

14. The method of claim 13, wherein the athletic performance data comprises at least one of speed data, distance data, acceleration data, pace data, power data, energy data, and/or location data.

15. The method of claim 13, wherein the athletic performance data is generated at different geographic locations.

16. The method of claim 13, wherein the comparison is used to determine a winner of an athletic competition.

17. The method of claim 13, wherein the athletic performance data is tagged to particular users, wherein tagging associates a code identifying a particular user or one of the sensing units.

18. The method of claim 17, further comprising:

receiving a request specifying a tag of the particular user or the one of the sensing units; and

providing athletic performance data associated with the tag.
