Abstract:
1. A method for assessing and reporting characteristics of a recreational ride event, comprising: a. placing a self-motion tracking device (SMTD) in close proximity to a recreational rider or recreational ride vehicle; b. determining at a first component of the SMTD motion information about relative motion of the SMTD or position information about a location of the SMTD; c. storing motion information or position information from the first component at a second component of the SMTD; and d. reporting and optionally qualifying motion information or position information from the first component at a third component of the SMTD; wherein the SMTD's self-motion tracking employs one or more accelerometers optionally in combination with a chronometer in a history circuit, optionally employs a navigational circuit, and wherein one or more of the first, second and third components is optionally controlled by an override element or a component that can respond to radio frequency identification signals.
