  • Publication number: 20240415430
    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.

  • Publication number: 20240355610
    Abstract: The disclosure relates to devices and methods for the spectrometric analysis of sample material located on a sample support, and in particular on a flat sample support plate, using axial time-of-flight analysis. One operating mode of the devices and methods comprises an adjustment of the pulse focal position for the abrupt ablation and/or abrupt desorption of sample material in a z-direction that is perpendicular to a tangential plane at the location of ablation and/or desorption at the sample support, and the selection of a suitable setting for an acceleration with time lag of the ablated and/or desorbed and ionized sample material onto a flight path. It can be particularly advantageous to use these devices and methods in mass spectrometry imaging (MSI). The devices and methods can, in particular, be used with laser desorption/ionization (LDI) and specifically matrix-assisted laser desorption/ionization (MALDI).

    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.
