Systems and methods for alignment and detection of a consumable component

摘要

Systems and methods for alignment and detection of a consumable component are disclosed herein. For example, a method for determining if a consumable component is coupled to a durable component to enable dispersion of a medicine is provided. The method includes determining if a signal from an electrical contact coupled to a durable component has changed an electrical state, and comparing the signal to a reference signal from a second electrical component coupled to the durable component. The method includes sampling a sensor coupled to the durable component to acquire sensor data indicative of a magnetic field observed by the sensor, and outputting data that a consumable component is coupled to the durable component if the signal is different than the reference signal, and the sensor data is within an acceptable range.

主权项

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.
