Abstract: A method comprises: receiving, in a computer system, a pattern record corresponding to a conveyor pattern of a conveyor belt in which patterns are randomly distributed; capturing, using the computer system, a first image of the conveyor belt while a first product is positioned on the conveyor belt; comparing, using the computer system, at least part of the first image with the pattern record to identify a first corresponding portion of the pattern record for the first image; assigning, using the computer system, a first identifier to the first product based on the first corresponding portion of the pattern record; and tracking, using the computer system, the first product using the assigned first identifier.

Abstract: One embodiment comprises a plasma processing system having a plasma chamber, a generator, a feedback component, and a controller. The feedback component is adapted to receive at least one first signal having a level dependent upon the power signal supplied from the generator to the chamber. A feedback output is adapted to emit a second signal to the controller, which is adapted to supply a third signal to the power generator. The third signal is configured to control the power generator to supply the power signal at a power level for a particular processing application. The power generator is further controlled by the controller to one of reduce and remove power from the plasma processing chamber and subsequently increase the voltage level until the power level reaches a threshold level. The power generator is further controlled to subsequently modulate the voltage until the voltage returns to a first voltage level.
