Method and apparatus for controlling positioning of a noninvasive analyzer sample probe

摘要: The invention relates generally to a probe interface method and apparatus for use in conjunction with an optical based noninvasive analyzer. More particularly, algorithm controls sample position attitude relative skin site before and/or during sampling. For example, head of module is controlled by along the normal-to-skin-axis. Preferably, positioned terms 3-D location x-, y-, z-axes orientated pitch, yaw, roll. Further, preferably prior contact tissue using indicators, such as non-contact distance feedback from capacitance sensor, contacting or non-contacting sensors, electrical sensors.
