Sensor and event system, and associated methods
First Claim
1. A n event system, comprising:
- a plurality of sensors for attachment to one or more athletes, and/or vehicles ridden by athletes, each of the sensors detecting sports metric information and wirelessly transmitting that information external to the sensors;
one or more repeaters for receiving the information; and
an operations terminal in communication with the repeaters to collect the information for transmission to a data informing device to communicate the information to end users.

Abstract
The system of the invention is used in measuring sports metrics at an event or venue. The system includes “n” sensors, “m” repeaters, a base station and an operations terminal. One or more sensors attach to each athlete (and/or the athletes vehicle) at the event or venue to determine a sports metric, e.g., airtime, g'"'"'s, drop distance, spin, rotation. The information about the sports metric is transmitted to one or more repeaters; and that information is relayed to the base station. The operations terminal provides a user interface, and may further interface with a judging station or TV to provide the sports metric, in near real-time, to judges, viewers and others at the event or venue.

4. A sensor, comprising a processor, a battery, a first accelerometer, a RF section, and a battery, the first accelerometer sensing vibration and/or free fall data, the processor connected with the accelerometer to process the data to determine sports metric information, the RF section communicating the information wirelessly to one or more repeaters, the battery providing power for the accelerometer, the processor, and the RF section.
- 5. A sensor of claim 5, further comprising second and third accelerometers, the processor connected with the second and third accelerometers to determine or refine the sports metric information.
- 9. A method of detecting airtime, comprising mounting at least one accelerometer with free fall detection to a athlete and detecting level shifts of acceleration data to determine airtime.
-
15. A method for determining airtime from acceleration data acquired from a ski, comprising mounting one or more accelerometers with the ski and monitoring frequencies of data from the accelerometers to detect airtime based upon change information in one or more frequencies of data, and processing the data with adaptive filters to compensate data for snow conditions and for reducing noise generated from ski clicks (i.e., where the skis connect during an airtime event).
