Patent ID: 8868147

Claim:
A noninvasive spectroscopic analyzer configured to determine an analyte property from a sample site of a body part, comprising: a sample probe having a sample probe tip; a controller for controlling attitude of said sample probe tip relative to localized curvature of the sample site based on an input; a first motor operating through a first pivot point positioned on a first concentric ring to move a second concentric ring to control pitch of said sample probe tip; and a second motor operating through a second pivot point positioned on the second concentric ring to move a third concentric ring to control roll of said sample probe tip; and wherein the controller adjusts the attitude including at least pitch and roll of said sample probe relative to the localized curvature of the sample site by controlling the first and second motors; wherein the input is configured to receive an input signal providing said controller with information about said attitude of said sample probe tip relative to the sample site.
