4C “Play by 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 nal 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 paint-

balls falling velocity will be obtained. This falling velocity will indicate if the hopper be-

ing 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 nal staged position. Because vital mea-

surements 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 sen-

sor will be used in processing when the ring 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 nal 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 nal staged position at the same time the bolt has begun its forward move-

ment. This cycle timing adjustment, made possible by 4C System Enhancing Eyes,

eliminates all wasted time in a markers ring sequence.
