System and methods for processing analyte sensor data
Systems and methods for processing sensor analyte data, including initiating calibration, updating calibration, evaluating clinical acceptability of reference and sensor analyte data, and evaluating the quality of sensor calibration. During initial calibration, the analyte sensor data is evaluated over a period of time to determine stability of the sensor. The sensor may be calibrated using a calibration set of one or more matched sensor and reference analyte data pairs. The calibration may be updated after evaluating the calibration set for best calibration based on inclusion criteria with newly received reference analyte data. Fail-safe mechanisms are provided based on clinical acceptability of reference and analyte data and quality of sensor calibration. Algorithms provide for optimized prospective and retrospective analysis of estimated blood analyte data from an analyte sensor.

Apparatus and method for non-invasive spectroscopic measurement of analytes in tissue using a matched reference analyte
A method is provided for building improved calibration models or for improving modifications to these models or validation of the models used in the non-invasive spectroscopic measurement of an analyte or attribute of tissue. The method uses a matched reference sample and measurement of that sample to ensure that the correct relationship between the spectra and analyte is made during the model building, modification or calibration process. A matched reference sample is one in which the analyte of interest or attribute of interest in the reference sample is representative of the analyte or attribute at the site being non-invasively sampled or the agreement between the reference concentration and the non-invasively sampled concentration is clinically significant.

An optical fiber bundle sensor is also disclosed in which individual microsphere sensors are disposed in microwells at a distal end of the fiber bundle and are optically coupled to discrete fibers or groups of fibers within the bundle. The identities of the individual sensors in the array are self-encoded by exposing the array to a reference analyte while illuminating the array with excitation light energy. A single sensor array may carry thousands of discrete sensing elements whose combined signal provides for substantial improvements in sensor detection limits, response times and signal-to-noise ratios.

The reference analyzer determines which of the instructions and data involve references outside of their domains, and determines which of the references outside of their domains are multiprocessor unsafe references. The report generator generates a report of the multiprocessor unsafe references. Also, a checker that dynamically determines where instructions and data result in domain violations when run on a multiprocessor system. The checker includes an interface to a table of purportedly microprocessor safe references by the instructions and data outside of their domains. The table preferably includes the domains to which the references are supposed to refer. The checker also includes a reference tracker that tracks references made by the instructions and data, and a comparator that determines, when a reference in the table of purportedly microprocessor safe references is encountered during execution of the instructions and data, if the reference is actually to a domain to which that reference is supposed to refer.

Temperature calibration methods and apparatus for optical absorption gas sensors, and optical absorption gas sensors thereby calibrated
ActiveUS20130301052A1Affect sensitivityColor/spectral properties measurementsGas analyser calibrationAnalyteOpto electronic
An optical absorption gas sensor has an LED light source and a photodiode light detector, a temperature measuring device for measuring the LED temperature and a temperature measuring device for measuring the photodiode temperature. The sensor is calibrated by measuring the response of photodiode current at zero analyte gas concentration and at a reference analyte gas concentration. From these measurement, calibration data taking into account the effect of photodiode temperature on the sensitivity of the photodiode and, independently, the effect of changes in the spectrum of light output by the LED on the light detected by the photodiode with LED temperature can be obtained. Calibration data is written to memory in the gas sensor and in operation of the gas sensor, the output is compensated for both LED and photodiode temperature. The LED and photodiode can therefore be relatively far apart and operate at significantly different temperatures allowing greater freedom of optical pathway design.
