Circuitry that controlled a number of relays, stepper motors, photogates, and switches.
CAD for circuitry done in MultiSim
Software side mocked up in MATLAB and implemented in LabVIEW. Two interfaces were needed: one for the patient and one for the caregiver. The caregiver would program an "insulin ladder" of dosages based on blood glucose levels.
The user interface would inform the user of their blood sugar levels and subsequently allow them to proceed with the process of administering insulin.
The ability to change the needle on an insulin pen was identified as an accessibility issue. This is a mock-up of a housing assembly that would use motors to remove, switch out, replace, and affix a new, unused insulin needle.
Another accessibility issue was the ability to manipulate the glucose monitor, so this assembly was built in order to house the glucose meter while it was connected to the electronics interface. Replacing the insulin strip cartridge was as simple as sliding the oversized handle back and forth. In future iterations this would all be automated.

Diabetes Accessibility Management System (DiAMS)
Developed a diabetes management system that improves accessibility to measuring blood sugar levels and injecting an appropriate amount of insulin on a daily basis.
Especially applicable to people with symptoms of advanced diabetes: neuropathy, retinopathy, hemiplegia, etc.
