Abstract
This invention allows for remote monitoring of the skier/skiing performance. The system consists of a various MEMS sensors embedded in skier clothing and equipment. These sensors measure instantaneous changes in acceleration in x/y/z axis and changes in earth magnetic field—relative to the skier position, to provide six degree of freedom in calculation of skier position as well as moments applied to the ski edge and forces experiences by the skier body. These sensors communicate with the monitoring application residing in the user wireless terminal (call phone) over the PAN wireless network. The instantaneous measurements are analyzed either locally or remotely and when the system is configured in an active mode, a corrective response to the MEMS actuators embedded in the ski or ski bindings may be send does changing the parameters of the run or provide enhanced safety.
