    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 having an optically detectable pattern such as gray code, and the infusion device includes a sensing arrangement having an optical sensor 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 embodiments, the optical sensor detects the sensed position of the shaft based on the detectable feature only when the reservoir is replaced and/or after each delivery of fluid to reduce power consumption.

    Abstract: Infusion devices, systems, and related operating methods are provided. A method of detecting an anomalous condition with respect to a fluid path involves providing energy to an actuation arrangement to produce actuation, wherein the actuation arrangement is coupled to a plunger configured to deliver fluid via the fluid path, monitoring an orientation of the actuation arrangement using a sensing arrangement, and detecting an anomalous condition based on the orientation of the actuation arrangement.

    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.

    Abstract: Embodiments are provided for dynamic management of charge. A method involves obtaining an estimated readiness time for an energy storage element, obtaining a target state of charge for the energy storage element, calculating an estimated charging time based at least in part on a difference between the target state of charge and a current state of charge, using a first charging rate to charge the energy storage element to an intermediate state of charge responsive to determining a time difference between the estimated readiness time and a first time is greater than the estimated charging time, maintaining the energy storage element at the intermediate state of charge, and responsive to determining a time difference between the estimated readiness time and a second time is less than the estimated charging time, using a second charging rate to charge the energy storage element to the target state of charge.
