Abstract: Advanced methods, apparatuses, and systems are presented for the real-time monitoring and precise control of substances undergoing phase transitions within a vacuum system, in particular, for lyophilization processes. Utilizing sophisticated interfaces, these techniques enable the visualization of phase diagrams depicting the equilibrium conditions of temperature and pressure for distinct substances. Real-time temperature and pressure data are seamlessly integrated and graphically represented on these phase diagrams. Furthermore, the methodology incorporates advanced regression models to accurately estimate mass quantities and employs dynamic environmental control curves for system parameter adjustments. These techniques encompass real-time data analysis, responsive adjustment inputs, intuitive graphical representations that ensure meticulous control and monitoring of phase transitions, thereby optimizing process monitoring and outcomes.

Abstract: A data collection and management system is provided for monitoring the condition of fuel tanks and for determining for each tank a degradation profile which provides an estimate of useful tank life and a prediction of when the tank is likely to need replacement before failure. The system is especially useful for monitoring residential fuel tanks and is also applicable for commercial and other tanks which are in a location where a tank failure would be harmful and potentially hazardous. A primary benefit of the system is to allow fuel dealers to identify tanks that should be replaced before they actually fail. The system provides the dealer with information which is useful in monitoring and servicing the fuel tanks of the dealers' customers.

Abstract: A tissue interface device (10) suitable for positioning on or about one or more artificial openings in a biological membrane of an organism and for coupling to a monitor and control unit and a vacuum source. The tissue interface device (10) comprises a housing (100), a sensor channel (130), and a sensor (150). The housing (100) defines an orifice (120), the orifice (120) having an open inlet port (122) on the bottom end (102) of the housing (100) and a distal end (124) that is in fluid communication with the sensor channel (130). The orifice (120) is in fluid communication with fluid that flows from the artificial opening formed in the biological membranes. The sensor channel (130) is for coupling to, and fluid communication therewith, the vacuum source. The sensor (150) is positioned in the sensor channel (130) in a flow path of the fluid for sensing a characteristic of the fluid as it flows out from the artificial opening. The sensor generates a sensor signal representative thereof.
