Abstract A training system for monitoring kinetic activities of an individual uses one or more transducers that are highly directionally sensitive to detect certain characteristics of a user's activity, such as motion, direction of motion, distance, velocity, and the like. The sensors have a housing which includes an acceleration-responsive transducer and circuitry responsive to output signals from the transducer to provide an indication to the user of certain characteristics of the activity. In a preferred embodiment, the sensor has a pointer indicating the direction of maximum sensitivity of the transducer, so that the user can orient it to preferentially detect motion in certain directions. The output signal supplied to the user preferably comprises a tone having one of several discrete frequencies corresponding to discrete range intervals of the transducer output.
A training system for kinetic activities, comprising: a transducer for mounting on a user, said transducer adapted to provide a first signal responsive to acceleration applied thereto as said user engages in said activity, means responsive to said first signal for generating an output signal indicating to said user a specific range, among a selected plurality of ranges, in which a characteristic of said first signal is located, to thereby enable said user to monitor said activities, wherein said means for generating includes motion distinguishing means having a frequency response characterized by a rising slope over a first portion thereof and a falling slope over a second portion thereof, for distinguishing between smooth steady signals and fast, non-repetitive signals and including a differentiator for providing said rising slope and an integrator for providing said falling slope.
