RESUMO

45 saliva samples of AIDS patients and 55 saliva samples in normal population were detected by the Surface-enhanced Raman spectroscopy (SERS) system. And the spectrum data were analyzed using the Support Vector Machine (SVM) algorithm, one of the data mining technologies. Statistical analysis showed that two groups were distinguished effectively. This study provided a new research direction of the quick non-invasive testing for AIDS.

RESUMO

Medical endoscope capsule is described from its construction principle and drive system.The scheme and function of the drive system,especially the driving velocity and the direction control for that based on FPGA,are introduced in detail.Experiments indicate that the micro-drive system,with a linear speed ranging from 0 to 10 mm/s,can move forward and backward,and turn left and right discretionarily.The availability of programmable logic device makes the system reliable and flexible.
