Bob Long 4c Eye System

Bob Long Marq Series 4-Eye Upgrade

SKU: 100696 Category: Brands: .

Description

This upgrade is for any of the Marq Series of Bob Long markers (Marq 6, Marq 7, Rapper, Closer)


The biggest advancement to the paintball marker since the inception of the 2 eye upgrade

 

The
set of eyes at the top of the breach reads the ball drop rate and tells
the bottom set of eyes when the ball will be in place and ready to be
fired, rather than waiting for the bottom set of eyes to read a ball in
place and then firing.  This action speeds up the firing sequence
dramatically


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
fire when a paintball has finally rested on the bottom of the breech,
therefore breaking the infrared beam and communicating “fire” 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 maximum rate of fire potential. Our engineering staff
at Bob Long Technologies has successfully implemented an advanced
system of optoelectronics which can increase a markers cycle rate
almost 40%. The multi-sensor 4C System Enhancing Eyes define the
absolute cutting edge in electronic marker technology.

There are
two instances of wasted time in a markers firing 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 provide 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 final staged position, we energize the solenoid coil early so when
a paintball reaches the final staged position the bolt has begun its
forward movement. This timing adjustment, made possible by 4C System
Enhancing Eyes, eliminates all wasted time in a markers firing
sequence.  


4C “Play and Play”

Here is a more
detailed description of how the 4C System Enhancing Eyes work. The time
it takes for a markers bolt to move back past sensors toward final open
position, allowing a paintball to fall, will be recorded. The time it
takes for the next paintball to pass by the top sensor while falling
will be recorded. The time difference between these measurements will
be calculated by the markers micro-controller and a paintballs falling
velocity will be obtained. This falling velocity will indicate if the
hopper being used is force-fed or gravity-fed. Use of a force-fed
hopper will result in the much higher falling velocity of paintballs.
Force-feeding also provides the best estimates of time required for a
paintball to fall into its final staged position. Because vital
measurements have been obtained by the 4C System Enhancing Eyes a
solenoids coil can now be pre-energized, factoring for mechanical
delay. Use of a gravity-fed hopper will result in a slow inconsistent
falling velocity. If a gravity-fed hopper is detected the
pre-energizing sequence is ruled out by the micro-controller and only
the bottom sensor will be used in processing when the firing sequence
should begin. Assume it takes 15mS to get a markers bolt moving forward
(calculating 20mS for a ball to fall past upper sensor into final
staged position at lower sensor). In this instance the solenoid can be
activated 5mS after the upper sensor is triggered. 15mS later the
paintball will reach its final staged position at the same time the
bolt has begun its forward movement. This cycle timing adjustment, made
possible by 4C System Enhancing Eyes, eliminates all wasted time in a
markers firing sequence.
