Abstract
The invention detects loft time and/or speed of a vehicle and/or person during activities of moving and jumping. A loft sensor detects leaving the ground and returning 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. A speed sensor can detect speed for selective display to the user, and height may also be determined during airtime.
