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: One or more analytes are detected non-invasively, and an access level is determined based on the one or more analytes. The one or more analytes indicate at least one of an identity and/or a current status of an individual seeking access, and the access level is based on the identity and/or status of the individual. Access to a location, a device, one or more device functionalities, a vehicle, one or more vehicle functionalities, and the like can be granted based on the access level.

Abstract: Access to a vehicle is controlled based on the presence or amount of one or more analytes in a potential driver. The one or more analytes are detected using a non-invasive analyte sensor. The non-invasive analyte sensor can be included in a steering wheel of the vehicle, a touch point in the vehicle, or a mobile device of the potential driver. The one or more analytes are indicative of an identity and/or a status of the potential driver. The status of the potential driver can include the presence of amounts above a threshold for one or more intoxicants and/or indicators of tiredness or sickness. The access is based on the identity and/or status of the potential driver as indicated by the presence or amount of the one or more analytes.
