Abstract: A user-mountable electronic device includes a housing, an accelerometer located within the housing, and at least one processor located within the housing. The accelerometer measures acceleration of the user-mountable electronic device and is configured to generate an output in response to detecting acceleration of the user-mountable electronic device that is greater than a minimum acceleration threshold. The at least one processor controls operation of the user-mountable electronic device. The at least one processor is configured to receive the output generated by the accelerometer and, in response thereto, to transition from a dormant or standby state of the user-mountable electronic device to an active state of the user-mountable electronic device.

Abstract: A fluid delivery system and a fluid conduit assembly suitable for use with the system are disclosed herein. The system includes a fluid infusion pump and a fluid conduit assembly coupled to the pump to deliver medication fluid to a user. The fluid conduit assembly includes a structure defining a flow path for the medication fluid, and a gas trapping filter coupled to the structure and positioned in the flow path. The gas trapping filter functions to filter particulates from the medication fluid and retain gas bubbles from the medication fluid. The structure includes at least one retaining feature to inhibit movement of the gas trapping filter.

Abstract: A method includes monitoring, via a device including an electrochemical cell, an electrical current that is proportional to an impedance of the electrochemical cell, and responsive to determining that the electrical current satisfies a threshold, measuring, via the device, a plurality of impedances of the electrochemical cell corresponding to a plurality of frequencies. The method further includes determining a charge transfer conductance and a solution resistance based on the plurality of impedances at fewer than four of the corresponding plurality of frequencies and determining the presence of electrochemical interference based on the solution resistance and the charge transfer conductance. The method further includes outputting an alert based on the determination of the presence of electrochemical interference.
