Abstract
The invention provides a targeting system used to direct a measuring system to a targeted sample site or volume. The targeting system increases analyte estimation performance by increasing precision and accuracy of sampling and/or by targeting an analyte rich tissue volume.
Claims22
An apparatus for noninvasive determination of an analyte property of a tissue sample, comprising:
- a targeting system configured to perform a measurement related to the tissue sample, wherein said targeting system generates a first signal, wherein said first signal comprises any of:
- a capacitance sensor signal;
- and
- a fluorescence signal;
- a measuring system, wherein said measuring system generates a second signal optically representative of the tissue;
- a controller, wherein said first signal from said targeting system is used by said controller during positioning of said measuring system relative to the tissue sample;
- and
- a data processing module, wherein said module generates said analyte property using said second signal.
An apparatus for noninvasive determination of an analyte property of a sample site of a tissue, comprising:
- an analyzer, comprising:
- a targeting system configured to perform a measurement related to the tissue sample, wherein said targeting system generates a first signal, wherein said first signal comprises any of:
- a capacitance sensor signal;
- and
- a fluorescence signal;
- a measuring system,
- wherein said first signal is used in dynamically positioning said measuring system relative to the sample site;
- and
- wherein said measuring system generates a second signal optically representative of the tissue;
- and
- a data processing module, wherein said module generates said analyte property using said second signal.
A method for noninvasively determining an analyte property of a sample site of a tissue, comprising:
- generating a targeting signal related to the tissue using a targeting system, wherein said targeting system comprises a portion of said analyzer, wherein said targeting signal comprises any of:
- a capacitance sensor signal;
- and
- a fluorescence signal;
- using said targeting signal in positioning a measuring system relative to the sample site;
- generating a noninvasive signal using said measuring system, wherein said noninvasive signal optically represents the tissue;
- and
- processing said noninvasive signal to yield said analyte property.
A method for noninvasively determining an analyte property of a sample site of a tissue, comprising:
- generating a targeting signal with a capacitance signal sensor in a targeting system, wherein said targeting system comprises a portion of an analyzer;
- using said targeting signal in positioning a measuring system relative to the sample site, wherein said step of positioning said measuring system comprises tilt movement of at least a portion of said measuring system in space,
- wherein an x-axis is defined along the length of a body part;
- a y-axis is defined across the body part;
- a z-axis is defined as orthogonal to the plane defined by the x- and y-axes;
- and said tilt is a rotation about said x-axis and/or said y-axis;
- generating a noninvasive signal using said measuring system, wherein said noninvasive signal optically represents the tissue;
- and
- processing said noninvasive signal to yield said analyte property.
