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 could be used in 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. The invention can also measure power absorbed by a user over a predetermined time interval.

[ Having described the invention, what is claimed as new and secured by Letters Patent is:] [1.]1. A system for measuring a power absorbed by a user on a moving vehicle over a surface and over a predetermined time interval, the system comprising:a sensor for detecting vibration of the moving vehicle and for generating signals indicative of the vibration, the vibration being substantially perpendicular to the surface;a microprocessor for processing the signals to determine the absorbed power over the predetermined time interval, the predetermined time interval being greater than about 500 milliseconds and less than about eight hours; andmeans for informing the user of the absorbed power.
