With the development of IR technology, there are increasing needs for surface BB. A novel surface blackbody (BB) with honeycombs for calibrating infrared (IR) imaging ranging 240~450K in the long IR wavelength bands of 3~15μm is developed and its features are experimental tested. Traditional radiant source of BB cavities are often with simple axisymmetrical structure, such as cylinder, cone, cylinder-cone,...
Though volume control and pressure control modes are both commonly used in mechanical ventilation, they have their shortcomings that the former may generate high peak pressures and the latter may be prone to unstable gas exchange. Therefore, a dual control mode, which attempts to deliver a constant tidal volume while limiting peak pressure or attempts to limit peak pressure but assures tidal volume...
Multi-motor synchronous transmission is a crucial technology in dyeing control systems. When the current system suffers from sudden unpredictable, uncertain or nonlinear changes, the traditional adaptive control method will fail to fulfill the task of synchronous control. A new fuzzy-extension control strategy, which combines fuzzy theory and the extension concept, is proposed here to solve this problem...
Respiratory systems are complex nonlinear systems that exhibit uncertain properties. Since patients' needs are not constant acceptable control of ventilator has to be adaptive to ensure that patients with severe pulmonary disease will obtain the required ventilation support. The AUTOPILOT-BT system was developed to reduce cognitive load of intensivists and at the same time improve mechanical ventilation...
