Annular confinement beam

The annular confinement beam or "ACB" is a vital component in virtually all *23rd Century to *24th Century transporter mechanisms. These safeguard the matter stream of an object, while the quantum factor is separately beamed to the target. The ACB generally uses back-up from the energizing coils and pattern buffer to ensure a successful and safe transport. Which also has a discriminating filter for any potentially dangerous substances (see: red alert). Disruptions in the cycle of rematerialization yields a large release of energy with risk to an increase of signal degradation.

safely out of the cell, while bullets passed harmlessly through them. And such when disruptor fire did the same in "The Undiscovered Country."
 * This may explain why, even in mid-transport, Kirk and the others in "Bread and Circuses" beamed

annular confinement beam.
 * The weapon discharge-deactivation from "Datalore" and "The Most Toys" was partly attributed to the

died from a Xindi weapon shot in "Countdown."
 * However, the 22nd Century had yet to deploy this method of transport when Major Hayes, J.
