During April, the team made improvements from the presentation in March. The verified exercise and heating components were attached to the headpiece and the remaining verification studies were completed. The IRB was accepted for validation testing. The validation studies followed the last of the verification testing. The final presentation, along with the final report, were updated and presented during the end of the month.

During March, the team planned to finish a poster by the third week in order to present verification results at NEBEC. The best option for the headpiece was ordered. The remaining components were added and experimentally tested in order to create the poster. The NEBEC poster included the introduction, other available options, design inputs, the prototype, calibrated temperature sensor data, temperature within the required range, and fit verification. The force of the resistive bands was tested after the presentation and added to the final design report. By the end of the month, the team presented the initial design.

During February, the team continued revisions of the initial draft for the Institutional Review Board. During the second week of February, project building started consisting of the exercise, heating, and headpiece components. The team collectively decided to make slight changes to verification protocol prior to IRB submission from the first semester report, in order to simplify the verification process. An updated timeline for the following months was also created to ensure the prototype is finished, along with testing. At the end of the month, the team reviewed the abstract for NEBEC and completed the FDA decision agreement. The final report was also started and updated throughout February from the first semester.
