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.

1. A method for determining if a consumable component is coupled to a durable component to enable dispersion of a medicine, comprising: determining if a signal from an electrical contact coupled to the durable component has changed an electrical state;comparing the signal to a reference signal from a second electrical component coupled to the durable component;if the signal is different than the reference signal, sampling a sensor coupled to the durable component to acquire sensor data indicative of a magnetic field observed by the sensor; andoutputting data that the 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. 2. The method of claim 1, further comprising: comparing the signal from the electrical contact to a second signal from a third electrical contact coupled to the durable component to generate a third signal; andcomparing the third signal to the reference signal. 3. The method of claim 2, further comprising: if the third signal is different than the reference signal, sampling the sensor coupled to the durable component to acquire sensor data indicative of the magnetic field observed by the sensor; andoutputting data that the consumable component is coupled to the durable component if the third signal is different than the reference signal, and the sensor data is within an acceptable range. 4. The method of claim 3, further comprising: outputting data that the consumable component is not coupled to the durable component if the third signal is different than the reference signal, and the sensor data is outside an acceptable range. 5. The method of claim 4, further comprising: resampling the sensor after a preselected time interval if the sensor data is outside of the acceptable range. 6. The method of claim 4, wherein outputting data that the consumable component is not coupled to the durable component further comprises: outputting error data to a visual device, audible device, tactile device and combinations thereof. 7. The method of claim 2, further comprising: if the third signal is substantially the same as the reference signal, sampling the sensor coupled to the durable component to acquire sensor data indicative of the magnetic field observed by the sensor; andoutputting data that the consumable component is coupled to the durable component if the third signal is substantially the same as the reference signal, and the sensor data is within an acceptable range. 8. The method of claim 7, further comprising: outputting data that the consumable component is not coupled to the durable component if the third signal is different than the reference signal, and the sensor data is outside an acceptable range. 9. The method of claim 1, wherein the durable component is an insulin infusion device having a fluid reservoir for holding insulin and the consumable component is a base plate, with the base plate cooperating with the insulin infusion device to enable dispersion of the insulin. 10. The method of claim 9, wherein determining if the signal from the electrical contact coupled to the durable component has changed electrical state further comprises: determining if the signal from the electrical contact has changed electrical state prior to dispensing insulin from the fluid reservoir. 11. A method for determining if a consumable component is coupled to a durable component to enable dispersion of a medicine, comprising: comparing a first signal from a first electrical contact coupled to the durable component and a second signal from a second electrical contact coupled to the durable component to a reference signal from a third electrical contact coupled to the durable component to determine if the consumable component has contacted the durable component;if at least one of the first signal and the second signal has changed electrical state while the reference signal has remained substantially the same, sampling a sensor coupled to the durable component to acquire sensor data indicative of a magnetic field emitted by a magnetic source on the consumable component;comparing the acquired sensor data to calibrated sensor data; andoutputting data that a consumable component is coupled to the durable component if at least one of the first signal and the second signal has changed electrical states and the acquired sensor data is within an acceptable range based on the calibrated sensor data. 12. The method of claim 11, wherein comparing the first signal and the second signal further comprises: using a comparator to compare the first signal and the second signal, the output of the comparator being a third signal; andcomparing the third signal to the reference signal. 13. The method of claim 11, wherein outputting data that a consumable component is coupled to the durable component further comprises: outputting connection data that indicates that the consumable component is coupled to the durable component if the first signal changed from a high voltage signal to a low voltage signal, the second signal changed from a high voltage signal to a low voltage signal and the reference signal is a high voltage signal. 14. The method of claim 11, wherein determining calibrated sensor data based on the acquired sensor data further comprises: averaging the sensor data sampled over a preselected number of times; andaccessing a look-up table stored on a data store to compare the average sensor data to the calibrated sensor data. 15. The method of claim 11, further comprising: determining if a position of the consumable component relative to the consumable component has changed if the average sensor data is outside the acceptable range based on the calibrated sensor data and the sampling of the sensor has been retried. 16. The method of claim 15, further comprising: outputting connection data that indicates that the consumable component is coupled to the durable component if the position of the consumable component has not changed. 17. A method for determining if a consumable component is coupled to a durable component to enable dispersion of a medicine, comprising: determining that a signal from a first electrical contact coupled to the durable component has changed an electrical state;comparing the signal to a reference signal from a second electrical contact coupled to the durable component;determining that the signal is different than the reference signal;sampling a sensor coupled to the durable component to acquire sensor data indicative of a magnetic field observed by the sensor based on the determination that the signal is different than the reference signal;determining that the sensor data is within an acceptable range; andoutputting data that the consumable component is coupled to the durable component based on the determination that the signal is different than the reference signal and the sensor data is within the acceptable range,wherein the durable component is an insulin infusion device having a fluid reservoir for holding insulin and the consumable component is a base plate, with the base plate cooperating with the insulin infusion device to enable dispersion of the insulin. 18. The method of claim 17, wherein determining that the signal from the electrical contact coupled to the durable component has changed electrical state further comprises: determining that the signal from the first electrical contact has changed electrical state prior to dispensing insulin from the fluid reservoir. 19. The method of claim 17, further comprising: comparing the signal from the first electrical contact to a second signal from a third electrical contact coupled to the durable component to generate a third signal; andcomparing the third signal to the reference signal. 20. The method of claim 17, further comprising: outputting data that the consumable component is not coupled to the durable component based on the comparison of the third signal to the reference signal and the sensor data.
