Systems and methods for determining energy experienced by a user and associated with activity
First Claim
1. A method for determining energy experienced by a person during activity over ground, comprising the steps of:
- determining forces of acceleration in a direction generally perpendicular to the ground;
processing signals representative of the forces of acceleration over a time interval defined by the activity to determine the energy; and
reporting the energy to the person.

Abstract
The invention detects the loft time and/or speed of a vehicle, such as a sporting vehicle, during activities of moving and jumping. A loft sensor detects when the vehicle leaves the ground and when the vehicle returns to the ground. A microprocessor subsystem converts the sensed information to determine a loft time. A display shows the recorded loft time to a user of the system. In addition, a speed sensor can detect the vehicle'"'"'s speed for selective display to the user. The invention is particularly well-suited to sporting activities such as snowboarding where users loft into the air on ski jumps and catch “air” time but have no quantitative measure of the actual time lapse in the air. Therefore, users in skiing can use invention to record, store, and playback selected information relating to their sporting day, including the total amount of “air” time for the day and information such as dead time, i.e., time not spent on the slopes.
