System And Method For Non-Wirelessly Determining Free-Fall Of A Moving Sportsman
First Claim
1. A system for non-wirelessly determining free-fall of a moving sportsman engaged in board sports, comprising:
- at least one accelerometer for detecting acceleration of the sportsman; and
a processor for processing data from the accelerometer to determine when the sportsman is in free-fall, the accelerometer and processor being connected non-wirelessly and by common housing to be worn or carried by the sportsman.

Abstract
A system for determining airtime of a moving sportsman includes at least one accelerometer for detecting vibration or acceleration of the sportsman. A processor in communication with the at least one accelerometer processing signals from the accelerometer to determine free-fall. A pressure sensor may be used to determine change in altitude and the processor may process signals from the pressure sensor with the accelerometer signals to determine airtime and drop distance during free-fall. A method for determining airtime of a moving sportsman includes processing data from one or more accelerometers attached to the sportsman, to determine when the sportsman is in free-fall, and determining a time period corresponding to the free-fall.
