Inventor Scott Leva demonstrates the Pressure Sensor Actuator
at the Scientific and Technical Awards demonstrations.

On Dexter, THE PSA was used on a single pull ratchet

to safely pull the performer 18 feet back

Ease of use. Easy set up. 100% accuracy on firing. The performer "safely" hits their mark every time. Extreme low impact. No joint shock or extreme impact. This new unit is being used on more sets today than ever before. Using a modified firing actuator with a flash drive installed, it takes Air Rams, Ratchets, and any other pneumatic devices used in stunts and special effects to a whole new "safer" level.

Unique state of the art software pairs with the actuator, reading the weight of the performer, and sends them to the spot that is set.
Lower pressure is used to keep the performer from any joint shock or impact. Most machines use from 500 to 1800 lbs of air pressure, while the machine with the pressure sensor actuator uses between 25 to 40 lbs.
