Abstract:
1. A fluid infusion device for dispersion of a medicine, comprising: a consumable component including a source of a magnetic field; a durable component including a first electrical contact, a second electrical contact and a third electrical contact, the first electrical contact and third electrical contact having a first electrical state when the consumable component is spaced apart from the durable component and a second electrical state when the consumable component is coupled to the durable component, the durable component including a sensor that observes the magnetic field emitted by the source; a contact control module that receives a first signal that indicates if the first electrical contact and third electrical contact are in the first electrical state or the second electrical state, and a second signal from the second electrical contact, and based on the first signal and second signal sets contact data that indicates if the consumable component is in contact with the durable component; and an alignment control module that receives the contact data, and based on the contact data samples the sensor to acquire sensor data, and the alignment control module outputs connection data that indicates whether the consumable component is coupled to the durable component based on the contact data and the sensor data.
