4C ENHANCING EYE SYSTEM
4C System Enhancing Eyes Theory and Functionality
For years, high performance paintball markers have minimized paintball breakage by
using a break-beam infrared sensor system commonly known as “eyes”. These eye
systems are traditionally positioned at the bottom of a markers breech. Single sensor
eye systems will only allow a marker to re when a paintball has nally rested on the
bottom of the breech, therefore breaking the infrared beam and communicating “re”
to the markers micro-controller. A broad spectrum of controlled testing has proven
this current eye system to be the predominant limiting factor when seeking out maxi-
mum rate of re potential. Our engineering staff at Bob Long Technologies has suc-
cessfully implemented an advanced system of optoelectronics which can increase a
markers cycle rate almost 40%. The multi-sensor 4C System Enhancing Eyes dene
the absolute cutting edge in electronic marker technology.
There are two instances of wasted time in a markers ring sequence (cycle time).
One instance occurs during the time taken for a micro-controller to energize the coil
of a solenoid. The second instance occurs during the time taken for a markers bolt
to respond to the recently transferred air pressure. This combined time can be 20mS
or greater. A marker cycling at 20 balls per second has a cycle time of 50mS, so
20mS would account for 40% of the total cycle time. Using multiple sensors around
the breech provides the information needed to accelerate the cycle time. A sensor
near the top of the breech indicates whether or not another paintball is ready to be
loaded. A sensor near the bottom of the breech indicates whether or not a paintball
is properly staged and ready to be propelled. These sensors working in tandem pro-
vide us with valuable time measurements and other consistency data. Because we
now know how long it takes paintballs to move down through the breech into the nal
staged position, we energize the solenoid coil early so when a paintball reaches the
nal staged position the bolt has begun its forward movement. This timing adjust-
ment, made possible by 4C System Enhancing Eyes, eliminates all wasted time in a
markers ring sequence.
