Contrast media is widely used in hospital for a better imaging of CT angiography. However, emergencies (such as needle eruption and capillary hemorrhage) may exist due to the extreme high speed of injection. A video-object-tracking system is implemented in this paper which can keep track of the patient's progress and sound an alarm in the event of danger. The MeanShift algorithm for real-time object...
Designing an appropriate power supply is a crucial technological problem when manufacturing an electronic transformer. Several schemes are researched in this paper. Finally, a new structure for designing such a power supply using a special current transformer (CT) set, which has three iron cores. One is closed core. The other two are open cores. Different cores have their own work region. A model...
