Patent ID: 7880874

Claim:
A method for counting particles, comprising: attaching a scanner to a particle sensor such that a particle conduit is completely surrounded by the scanner and the particle sensor but for a first opening where air enters the particle conduit and a second opening where air exists the particle conduit; raising the scanner and the particle sensor slightly above a surface; passing a stream of airflow through a channel; filtering out external air before particles enter the scanner via a scanner head; sucking the stream of airflow from the channel, whereby concentrated particles are forced into the particle conduit; forcing the stream of airflow through the use of a vacuum source, the vacuum source powered to suck particles through a created stream of airflow; maintaining a constant flow after particles have been counted via the vacuum source and a vacuum tubing; vacating the stream of airflow and all remaining particles through the use of an exhaust element; and providing power to the scanner via a power and signal line, the power and signal line also serving to calculate and emit signals to the scanner.
