Nineteen open-fronted (class I) safety cabinets were subjected to spore containment and airflow tests, which suggested that a flow of 0.75 m/s was the minimum required for safe operation; further tests on three of the cabinets were repeated at different air speeds and confirmed this. The airflow is required to overcome the effect of laboratory or external air currents. Contamination of surfaces...

Wireless channel measurement results for 60 GHz within a closed metal cabinet are provided. A metal cabinet is chosen to emulate the environment within a mechatronic system, which have metal enclosures in general. A frequency domain sounding technique is used to measure the wireless channel for different volumes of the metal enclosure, considering both lineof-sight (LOS) and non-line-of-sight (...

In everyday life we are often faced with the need to monitor the contents of some kind of container e.g. the contents of a medicine cabinet or a tool box. In this paper we show that this entire class of scenarios has similar features and properties. To remove the annoyance associated by the user with this monitoring task we propose a smart box concept. In this concept the monitoring is facilita...
