Space-based systems, monitoring

We have designed and built a microprocessor-based Data Acquisition System for radon research that is currently being used for field studies. Among other things the system will be used to monitor radon levels in conjunction with other meteorological data in a controlled space over relatively long periods of time.

It is easily understood that if the aseptic operation is performed in a separated small space from which personnel have been completely excluded, the necessity for room classification based on particulate and environmental microbiological monitoring requirements may be significantly reduced. In other words, critical operations in an aseptic area should be performed in the smallest space, and intervention by personnel should be minimized by indirect means through the use of protective glove ports and/or half suits. Application of these methods can minimize the chance of contamination. Following are such systems currently in place to reduce the contamination rate in aseptic processing. 

Based on the above items listed for CRO audits, the laboratory systems audit should assess if the laboratory participates in routine external quality assessments, whether sample handling is adequate and transparent and the risk of mix-ups is minimized. Proper documentation should be available for all sample movements and adequate space at refrigerators/freezers/cold rooms is mandatory. Refrigerators/freezers/cold rooms must be temperature-monitored, connected to an alarm system, be maintained, cleaned and calibrated as required. 

Aspects of asynchronous and synchronous object management in a distributed environment and the data models for the manipulation of lead time have thus far been in the foreground in systems for designing objects in a virtual work environment. Here, the data models are oriented by existing CAD standards or they focus on application protocols for the product data model STEP, with these protocols still to be developed. These systems are also not frilly immersive, but they are monitor based in connection with relevant 3D input tools (e.g., space mouse, trackball). Handling aspects of virtual prototypes in an immersive VE have been studied, for example, at the University of Wisconsin-Madison (Dani and Gadh 1996).
