    ABSTRACT: The technology of visible-infrared (Vis-NIR) spectroscopy for tongue inspection was used for the noninvasive prediction of red blood cell counts (RBC). Reflectance spectra on the tongue tips of 240 volunteers were collected, and the tongue picture was recorded at the same time. Samples were separated into two parts: calibration sample and prediction sample. Spectra were then subjected to a partial least squares regression (PLSR) analysis. The correlation between the data and prediction of HCT yielded calibration samples value of 0.991, and RBC levels of prediction samples predicted by this model from Vis-NIR spectra provided a coefficient of determination in prediction of 0.994 with an average relative error of prediction of 0.81%, and a root mean square error of prediction of 0.472. Experiment results showed that the correlation between tongue and RBC exists, and also demonstrated that the tongue can be used as the measure site for noninvasive prediction of RBC. From the results of prediction model and prediction results we can conclude that reflectance spectroscopy of tongue can be used to predict the RBC noninvasively.

    ABSTRACT: Because of low energy transmission efficiency of the transcutaneous coupling power supply device, the factors affecting inefficiency are analyzed and an implantable stimulator external powered is designed. The circuit consists of High-frequency inverter module, transcutaneous transformer and an isolated pulse generator. The circuit realizes that the polarity, amplitude, frequency and pulse width of stimulating pulses are adjustable and controllable. The distance between two transcutaneous coupling coils is the thickness of human skin, usually 5~15mm. Through practical tests at a distance of 10mm, experimental results show that the maximum transmission efficiency is 7.66% at the high-frequency carrier of 300KHz. The variable range of amplitude is between 0 and 10 voltages. The range of frequency is between 100 and 300Hz. So the designed circuit meets the demand of implantable stimulators.
