156A Finals Week

Current Status - Developing a cylindrical chamber with reinforcement to it.

During last week, each member in a team did analysis on individual components to decide which component to be used on our device. Then we discussed on what part to use to reinforce the chamber, and as of now, we decided that the metal rings would be a good choice. Then we worked on revising our presentation with emphasis on our 4 main functional requirements: holding negative pressure, a supine position, self-generative and no collapsing.

Goals for Next Week.

• Final Presentation- Give presentation that helps audience to understand our project and what we are working on.

• Find Adequate rings - compare different rings and choose the ring that's the most suitable for our purpose.

• Functional Requirements - 4 main functional requirements addressed above are important; weight and storage is not as important.
