    Abstract: Apparatus are provided for infusion devices and related systems and operating methods. An exemplary system includes a motor, a sensing arrangement coupled to the motor to provide output indicative of a detected characteristic of the motor when the sensing arrangement is enabled, and a module coupled to the sensing arrangement to periodically enable the sensing arrangement while the motor is idle and detect potential unintended motion of the motor based on the output from the sensing arrangement while periodically enabling the sensing arrangement. In some embodiments, the motor includes a rotor configured such that its rotation provides translational displacement of a plunger in a fluid reservoir, and the sensing arrangement includes one or more sensors configured to provide output indicative of a detected magnetic field of the rotor magnet.

    Abstract: A fluid infusion device and related operating methods are presented here. An exemplary embodiment of the device includes a drive motor assembly, a force sensor associated with the drive motor assembly, and a reservoir cavity that accommodates fluid reservoirs. An exemplary operating method for the device obtains force measurements for a reservoir seating action of the drive motor assembly, where the force measurements indicate measures of force imparted to the force sensor during the reservoir seating action. The method continues by determining that a vent in the reservoir cavity is blocked, based on an analysis of the force measurements, and by initiating corrective action for the fluid infusion device in response to determining that the vent in the reservoir cavity is blocked.

    Abstract: Apparatus are provided for sensor assemblies and related medical devices. An embodiment of a sensor assembly includes a rigid structure and a beam structure having an outer portion in contact with the rigid structure and an inner portion. The beam structure includes one or more beams extending between the outer portion and the inner portion of the beam structure and a cantilevered portion extending from the inner portion to inhibit displacement of the inner portion toward the rigid structure. Each beam has a sensing element disposed thereon.
