Getting a training weapon with a harmless red laser to have the same recoil action when the trigger is pulled as the actual assault rifle takes some clever engineering. Without the recoil, police and military training was unrealistic. To achieve the recoil and improve the training experience, Humphrey Products’ engineers squeezed a custom valve manifold/cylinder assembly inside the stock of the training rifle.
The concept of using pneumatics for recoil is not necessarily new. However, the issue in this application was simulating the same recoil level while fitting the valve and manifold inside the rifle butt without having obvious external evidence of the pneumatics. According to David Maurer, director of sales for Humphrey Products, a critical aspect of the design was the size of the piston area in Humphrey’s 310 valve. Since it is quite large, it is capable of providing a good jolt, but this is just one of the design criteria. “You want to come as close as possible to simulate the actual weight and feel and balance of the weapon,” says Maurer.
In Humphrey’s design, the rifle’s trigger activates the solenoid on the valve that causes a custom manifold to supply a burst of air to the cylinder. When the single-acting cylinder rod extends, it strikes the plate in the butt stock. The force of the cylinder rod against the stock butt plate simulates real recoil.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
