Abstract: A sensor is controlled to non-invasively detect one or more analytes in a subject based on the biological identity or a status of the subject. The biological identity or status can be obtained either from another device or from detection by the sensor itself. The detection of the analytes based on the biological identity or the status can include generating a transmit signal, transmitting the signal into the subject, obtaining a response, and processing the response to determine the presence or amount of one or more analytes. The characteristics of the transmit signal, the processing of the response, and/or the one or more analytes being detected can be selected based on the identity and/or the status of the subject.

Abstract: Establishing an analyte database using analyte data that has been obtained using one or more non-invasive analyte sensors, and using the analyte database to analyze data obtained using a non-invasive analyte sensor. Once the analyte database is established, the analyte database can be updated with new analyte data, and the analyte database can be used to analyze the new analyte data to derive information from the new analyte data. For example, in the case of a human target, the new analyte data together with the analyte database can be used to predict an actual or possible abnormal medical pathology of the human target.
