  • Projectile simulation
    Patent number: 3948522
    Abstract: The aimed launching of projectiles is simulated by means of an electroacoustic transducer which is energized to emit a beam of sound waves, preferably at ultrasonic frequency. A cooperating target also employs an electroacoustic transducer and apparatus for indicating reception of the sound beam by that transducer. The emitter transducer may be mounted in a simulated firearm, or other projectile launcher, while the receiver transducer may be mounted on a simulated target.
