Abstract: The invention detects the loft time, speed, power and/or drop distance 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 controller 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. A power sensing section informs the user of expended energy, which can be compared to other users. A drop distance sensing unit informs the user of the peak height of a jump, during an airtime. Gaming on the internet is facilitated to connect worldwide sport enthusiasts.

Abstract: The invention monitors the driving range and tracks golf balls from users at the driving range and informs those users of characteristics such as driving distance. A solid state camera images the range, and preferably one or more tee-off positions, and collects frames of image data to track a ball's motion through space. Simulation routines augment that track and assist in isolating the start location as well as where the ball lands, or would have landed had it not been obstructed (e.g., by a net). Preferably, the invention also determines the ball's position in 3-D to increase the accuracy. In one technique, two or more solid state cameras are used, and synchronized, to specify stereoscopic imaging. In another technique, the ball's energy or physical extent is used to determine an absolute distance between the camera and the ball. A computer at the club house monitors the entire system and further manages a network including an array of displays at the several tee off positions.
