Exhalation profile and elimination kinetics of mouth alcohol

Mouth alcohol (MA) is a potential source of error in alcohol breath-testing. Although utilized commercially for MA-detection, the exhalation profile of breath samples containing MA has not been systematically studied before. To characterize the exhalation profile of MA, volumetric expirograms of single-exhalations containing MA were examined. In addition, to explain reports of unusual slow elimina

Grafchart Applications

An overview of Grafchart, a graphical language for sequential control applications is given. Grafchart is based on Grafcet/SFC to which it adds concepts from high-level Petri nets, Statecharts and object-oriented programming. Applications of Grafchart in batch control, alarm filtering, decision support, and FMS are briefly presented.
