Abstract: A portable system is disclosed for displaying a real time video to a user wearing video glasses and while engaging in exercise. The system comprises a motion sensor for attachment to the of the user, with sensor generating a plurality of consecutive signals based upon the motion of the user's body. The video glasses of the system also comprise a video frame sequence stored in a memory; a programmed video processor for modifying the video frame sequence as a function of the difference in magnitude between the consecutive signals generated by the motion sensor; and a video display for displaying the modified video frame sequence with the display of the modified video frame sequence changing as a function of the body motion of the user.

Abstract: A sound generation apparatus for an electric vehicle that is being operated by a driver comprising: a sound generation circuit attached to a wheel of the electric vehicle; Faraday generators for supplying pulses of electrical current within the circuit while the wheels of the vehicle are rotating; a battery for supplying battery power within the circuit; a pulse activated power controller that is activated upon the receipt of an initial pulse form one of the Faraday generators and controls the supply of battery power within the circuit; and a programmed microcontroller that uses the battery power to simulate a motor sound for the electric vehicle and uses additional pulses from the Faraday generators to determine whether the vehicle is accelerating, decelerating or moving in reverse and, based upon its state of motion, modifies the simulated motor sound.
