Software Operating System

Because there are multiple tasks to be performed simultaneously, most robotic systems for drug screening operate with software that operates in a multitasking environment. The controller issues device commands, receives data, and controls the system simultaneously. With today's increasingly complex systems, multitasking capability is a requirement. Due to their cost, availability, reliability, and user familiarity, standard personal computers are frequently used as system controllers. For a variety of reasons, at the time of this writing, most software for drug screening robotic systems operates in a Windows ® NT environment. The Windows graphical user interface (GUI) has become widely accepted in drug screening laboratories, making it easy to train new users and assuring familiarity between different systems and different vendors.
