Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Hula hoops and ropes for prototyping reinforcement hoops purchased.
Tests of reinforcement fixtures have been conducted.
Tests show a clear reduction of radial deformation in the air duct.
Waistband seal improvement prototype tested, and the obtained pressure response showed doubled time constant when the gaps closed.
Accomplishments from Previous Week
Prototype with hula hoop was tested.
Tested pressure seal around the waist with and without electronic wires.
Gathered carbon fiber for reinforcement hoops.
Calculated optimal OD and thickness of steel tubing for reinforcement hoops
Ordered closed cell foam sample from McMaster for prototyping waistband seal.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Test stainless steel option for reinforcement hoops (Jen, Geoffrey).
Test carbon fiber options for reinforcement hoops (Brian, Jackie)
Design installation for reinforcement hoops (Jen, Jackie, Brian, Geoffrey).
Purchase closed-cell foam for further prototyping (Jen, Brian, Jackie, Geoffrey).
