Abstract: Systems and methods disclosed here provide ways to discriminate fault types encountered in analyte sensors and systems and further provide ways to process such discriminated faults responsively based on sensor data, clinical context information, and other data about the patient or patient's environment. The systems and methods thus employ clinical context in detecting and/or responding to errors or faults associated with an analyte sensor system, and discriminating the type of fault, and its root cause, particularly as fault dynamics can appear similar to the dynamics of physiological systems, emphasizing the importance of discriminating the fault and providing appropriate responsive processing. Thus, the disclosed systems and methods consider the context of the patient's health condition or state in determining how to respond to the fault.

Abstract: Systems, devices, and methods are disclosed for wireless communication of analyte data. One such method includes, during a first interval, establishing a first connection between an analyte sensor system and a display device. During the first connection, the method includes exchanging information related to authentication between the analyte sensor system and the display device. The method includes making a determination regarding whether authentication was performed during the first interval. During a second interval, the method may include establishing a second connection between the analyte sensor system and the display device for transmission of an encrypted analyte value, and bypassing the exchanging of information related to authentication performed during the first connection.

Abstract: Disclosed are devices, systems and methods for power management in an electronics unit of a sensor device, e.g., such as in a continuous analyte sensor system. In some example embodiments, there is provided a method that includes monitoring, by a controller of a sensor electronics module, counts associated with signals received from a sensor device for a first period of time. The method also includes comparing a number of received counts with one or more benchmarked count thresholds, and determining whether to initiate an operational mode of the sensor electronics module based on the comparison. Related systems, methods, and articles of manufacture are also described.

Abstract: Systems and methods for processing, transmitting, and displaying data received from a continuous analyte (e.g., glucose) sensor are provided. A sensor system can comprise a sensor electronics module that includes power saving features, e.g., a low power measurement circuit that can be switched between a measurement mode and a low power mode, wherein charging circuitry continues to apply power to electrodes of a sensor during the low power mode. The sensor electronics module can be switched between a low power storage mode and a higher power operational mode via a switch, e.g., a reed switch or optical switch. A validation routine can be implemented to ensure an interrupt signal sent from the switch is valid. The sensor can be physically connected to the sensor electronics module in direct wireless communication with a plurality of different display devices.

Abstract: Systems and methods for a continuous monitoring of analyte values received from an analyte sensor system are provided. One method for a wireless data communication between an analyte sensor system and a mobile device involves storing identification information associated with a transceiver of the analyte sensor system, the identification information entered by a user of the mobile device via a custom application running on the mobile device; causing the custom application to enter a background mode; searching for advertisement signals; receiving an advertisement signal from the transceiver; authenticating the transceiver based on the identification information; prompting the user to bring the custom application to a foreground mode; causing the custom application to request a confirmation from the user that a data connection with the transceiver is desired; receiving the confirmation from the user; and completing the data connection with the transceiver.
