    摘要: 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.

    摘要: The invention disclosed herein relates to systems and methods for detecting, calculating, and displaying the time-of-flight or hang-time of a moving and jumping object such as a skier or snowboarder by using at least one accelerometer secured within a small wearable device. In one embodiment, the inventive device comprises: a static acceleration detection means for detecting the static acceleration of the object over at least first, second, and-third periods of time as the object respectively moves, jumps in at least first, second, and third trajectories, and lands at least first, second, and third times along the surface thereby defining at least respective first, second, and third time-of-flight events; a calculating means for determining the approximate time-of-flight of the object during the first, second, and third time-of-flight events; and a display means for displaying in a readable format the approximate time-of-flights associated with the first, second, and third time-of-flight events.
