    • A method to measure a concentration of a substance, such as glucose, in a body comprising changing the temperature of the surface of a body from a first temperature to a second temperature, then changing the temperature of the surface of the body from the second temperature back to the first temperature, and measuring a first amount of infrared ("IR") radiation absorbed or emitted from the surface of the body in a first wavelength band, and a second amount of IR radiation absorbed or emitted from the surface of the body in a second wavelength band during the periods of changing temperatures. The method also measures a temperature at the surface of the body and an ambient temperature. A normalized ratio parameter is calculated and the concentration of the substance in the body is determined by correlating the normalized ration parameter with the body surface temperature and the ambient temperature.
    • 一种测量身体中物质如葡萄糖的浓度的方法,包括将身体表面的温度从第一温度改变到第二温度,然后从第二温度改变身体表面的温度 回到第一温度,并且测量在第一波长带中从身体的表面吸收或发射的第一量的红外(“IR”)辐射和从身体的表面吸收或发射的第二量的IR辐射 在温度变化期间处于第二波长带。 该方法还测量身体表面的温度和环境温度。 计算归一化比率参数,并通过将归一化比例参数与体表温度和环境温度相关联来确定体内物质的浓度。
