Abstract: A fluid infusion device includes a pump having a rotor and a stator. A rotor cam element rises from a reference surface of the rotor. The stator includes a cam element having a stator cam surface. The cam elements axially displace the rotor as the rotor revolves. Inlet and outlet valves open and close as a function of angular and axial position of the rotor. A motor actuates the rotor to pump fluid to a body, via a subcutaneous conduit. First and second contact elements are located on the rotor. A sensing element on the stator cooperates with a detection circuit to detect when the sensing element makes contact with the first sensor contact element and the second sensor contact element. The detection circuit monitors a detection signal obtained from the sensing element to determine an operating condition of the fluid pump mechanism.

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.
