    Abstract: A pumping system including a plurality of pumps each having a pump fluid outlet, a drive shaft, a prime mover, and fluid displacing members operatively coupled with the drive shaft. A common fluid conduit may be fluidly coupled with each pump fluid outlet. A control system of the pumping system includes position sensors operable to generate information relating to phase and/or speed of each pump, pressure sensors operable to generate information relating to fluid pressure spikes, and a controller in communication with the position and pressure sensors. The controller is operable to cause the prime movers to adjust the phasing of the pumps with respect to each other, based on the information relating to fluid pressure spikes, and synchronize the speed of the pumps.

    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.
