    Abstract: Infusion systems including infusion devices and consumables and related operating methods are provided. An exemplary method of operating an infusion device operable to deliver a fluid influencing a physiological condition to a body of a user involves a control module of the infusion device obtaining calibration data associated with a consumable coupled to the infusion device via an interface of the infusion device, determining a delivery command for delivering the fluid to the body of the user based at least in part on the calibration data, and operating a pumping mechanism to deliver the fluid from a reservoir of the consumable to the body of the user in accordance with the delivery command.

    Abstract: Apparatus are provided for infusion devices and related control systems and methods. In one embodiment, an infusion device includes a voided portion adapted to receive a shaft portion that includes a shaft coupled to a plunger of a reservoir. The shaft portion includes a detectable feature, and the infusion device includes a sensing arrangement proximate the voided portion to sense the detectable feature. In some embodiments, a control module is coupled to the sensing arrangement to determine a remaining amount of fluid in the reservoir based at least in part on the sensed position of the detectable feature. In other embodiments, the control module identifies an anomalous condition based at least in part on the sensed position of the detectable feature.

    Abstract: A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.
