Abstract: Systems and methods are provided for detecting changes or fluctuations in an analyte concentration signal that are abnormal, e.g., exceed a predetermined threshold, current trend of analyte concentration measurements, etc. Signals indicative of an analyte concentration in a host may be received from an analyte sensor. The signals may be monitored, and a determination can be made as to whether there is a change in the signal. Upon detecting such a change, the change can be compensated for such that a representation of the signal indicates the analyte concentration. Optionally, the cause of the detected changes or fluctuations can also be determined and information regarding the detected changes or fluctuations can be recorded and analyzed for subsequent optimization of the systems and methods as well for transmitting alerts, notifications, etc. to a user to take corrective action.

Abstract: Devices and methods for providing a user with alerts are provided. The alerts may take different forms, such as an output to a display, a speaker, a vibration module, a shock module, etc. The alerts provide the user with sufficient information to take appropriate action, but the devices may be of limited functionality to enhance their compactness, discreetness, wearability, etc., while also lowering their cost to manufacture.

Abstract: Methods and apparatus are provided for communication among display devices and sensor electronics unit in an analyte monitoring system. The analyte monitoring system may include a sensor that is configured to perform measurements indicative of analyte levels. The sensor may be communicatively coupled to the sensor electronics unit. The sensor electronics unit may be configured to transmit data indicative of analyte levels to the display devices using one or more communication protocols. Furthermore, the sensor electronics unit may be configured to operate in multiple modes, and switch between the modes in response to commands received from the display devices. Related systems, methods, and articles of manufacture are also described.

Abstract: Systems and methods are provided that address the need to frequently calibrate analyte sensors, according to implementation. In more detail, systems and methods provide a preconnected analyte sensor system that physically combines an analyte sensor to measurement electronics during the manufacturing phase of the sensor and in some cases in subsequent life phases of the sensor, so as to allow an improved recognition of sensor environment over time to improve subsequent calibration of the sensor.
