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.

Systems for managing pressure in a fluid reservoir chamber of a fluid infusion device are provided. For example, a fluid infusion device comprises a housing having a reservoir chamber that receives a fluid reservoir and a pump chamber. The fluid infusion device also includes a drive system contained within the pump chamber, and the drive system includes a slide that is movable relative to the fluid reservoir. The slide includes a proximal slide end that cooperates with a portion of the fluid reservoir to dispense fluid, and the proximal slide end has a projection. The fluid infusion device includes a pressure management system defined in the projection of the slide. The pressure management system includes at least one bore defined through the projection. The at least one bore is spaced a distance apart from a perimeter of the projection to vent air from the reservoir chamber into the pump chamber.

The problems of easily lost locking pins and lack of compatibility with traditional footwear in providing replaceable heel systems for the footwear are solved by a heel system comprising a locking unit having a first bore and a shoulder in the first bore; a heel unit having a second bore; and a locking member in the first bore, wherein the heel unit is attachable and detachable to the locking unit by sliding the heel unit, wherein the locking member extends from the first bore into the second bore when the footwear assumes ordinary orientations, wherein the locking member is disposed into the first bore when the footwear assumes out of the ordinary positions, and wherein the locking member has a stop which engages the shoulder in the first bore.

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.
