Claim:
1. A medical device comprising: a first device portion; a second device portion configured to connect to a reservoir and to be selectively operatively coupled with the first device portion; a drive device contained in the first device portion, the drive device arranged to selectively drive infusion media from the reservoir when the reservoir is connected to the second device portion and the first and second device portions are operatively coupled together; a magnetic field source supported on the second device portion, the magnetic field source having a magnetic field; a sensor supported on the first device portion for detecting the magnetic field of the magnetic field source when the first and second device portions are operatively coupled together; electronics associated with the sensor and configured to control the drive device based, at least in part, on a detection of the magnetic field of the magnetic field source; wherein the electronics are configured to determine whether a gauss level of the magnetic field detected by the magnetic field sensor is within a predefined range.
