Abstract: A diagnostic Electrochemical Impedance Spectroscopy (EIS) procedure is applied to measure values of impedance-related parameters for one or more sensing electrodes. The parameters may include real impedance, imaginary impedance, impedance magnitude, and/or phase angle. The measured values of the impedance-related parameters are then used in performing sensor diagnostics, calculating a highly-reliable fused sensor glucose value based on signals from a plurality of redundant sensing electrodes, calibrating sensors, detecting interferents within close proximity of one or more sensing electrodes, and testing surface area characteristics of electroplated electrodes. Advantageously, impedance-related parameters can be defined that are substantially glucose-independent over specific ranges of frequencies. An Application Specific Integrated Circuit (ASIC) enables implementation of the EIS-based diagnostics, fusion algorithms, and other processes based on measurement of EIS-based parameters.

Abstract: A method of generating a visual representation of a complex medical diagnosis includes receiving a first signal corresponding to a measurement of a patient biological condition. A second signal corresponding to a measurement of a patient performance condition is also received. The first and second signals are processed and a visual representation of a diagnostic assessment is generated. The diagnostic assessment is based at least in part on the patient biological condition and the patient performance condition. The visual representation is marked with the measurement of the patient biological condition and the measurement of the patient performance condition.

Abstract: Various examples are directed to systems and methods of and using analyte sensors. An example analyte sensor system comprises an analyte sensor and a hardware device in communication with the analyte sensor. The hardware device may be configured to perform operations comprising applying a first bias voltage to the analyte sensor, the first bias voltage less than an operational bias voltage of the analyte sensor, measuring a first current at the analyte sensor when the first bias voltage is applied, and applying a second bias voltage to the analyte sensor. The operations may further comprise measuring a second current at the analyte sensor when the second bias voltage is applied, detecting a plateau bias voltage using the first current and the second current, determining that the plateau bias voltage is less than a plateau bias voltage threshold, and executing a responsive action at the analyte sensor.

Abstract: A non-invasive electronic patient monitor tracks one or more physiological parameters of a patient, such as intravascular volume index (IVI), extravascular volume index (EVI), total hemoglobin (SpHb), impedance, and/or weight. The patient monitor determines if one or more of the physiological parameters are within a predetermined range. The patient monitor activates an alarm if one or more of the physiological parameters are outside the predetermined range and indicates a patient can be experiencing edema and/or heart failure, or sepsis.

Abstract: Certain configurations of removable oral devices are described. In some instances, the removable oral device includes a palatal element. In certain configurations, the palatal element may comprise a variable hardness at different areas, e.g., edges can be softer than other areas of the removable oral device. In other instances, the removable oral device may comprise two or more individual palatal elements which together can form the palatal element and permit user adjustment of the oral volume. Various materials used in the palatal element are described. Sensors and other on-board devices are also described.
