Connection and alignment detection systems and methods
First Claim
1. A delivery system for delivering fluidic media to a user, comprising:
- a first housing portion to be carried by the user;
a second housing portion to selectively operatively engage with and disengage from the first housing portion, and to support a reservoir having an interior volume for containing the fluidic media;
a drive device supported by the first housing portion such that upon the first housing portion and the second housing portion being operatively engaged, the reservoir is operatively coupled to the drive device;
a first interactive element supported on the first housing portion, wherein the first interactive element is a magnetic sensor;
a second interactive element supported on the second housing portion at a location to be interactable with the first interactive element, wherein the second interactive element is a magnetic material, and a field direction of the magnetic material or a gauss level is sensed by the magnetic sensor; and
electronics including a processor configured to receive signals from the sensor and compare the signals with pre-stored values or thresholds.

Abstract
A medical device includes a first housing portion (FHP) and a second housing portion (SHP) configured to be to be movable relative to each other from a first position to operatively engage at a second position to couple at least one of a drive device and a needle-inserting device supported by one of the FHP and the SHP to a reservoir supported by the other of the FHP and the SHP. Electronic circuitry configured to detect at least one of a first magnetic interaction between a magnet and at least one of a first magnetically attractive material and a first magnet-responsive device and a second magnetic interaction between the magnet and at least one of a second magnetically attractive material and a second magnet-responsive device, and to provide a signal or a change in state in response to detecting at least one of the interactions.
