Requirements were determined for the pump, and a range of flow rates found. Pump will be ordered.

The next main focus of development will be the electronics and data collection subsystem. This subsystem was considered at low level design during phase three, and will be expanded on in phase four.

Focused on three main areas of necessary requirements: pump, cup manufacturing, and data collection. Requirements and protocols determined.

Tests will be carried out according to plan to evaluate the success of the alpha prototype and additional materials.

Cup probe heads were manufactured, other system components were selected. Materials are in process of being ordered.

The alpha prototype will be tested according to the testing plan. Results will help to inform redesign for the beta prototype. Analyses may be revisited if necessary.
