Week 3 was a busy week with the preparation and presentation of the mid-presentations. We presented our designs as well as discussed the engineering process. We created up to over 100 possible mechanisms, designs, and ideas which was hard to narrow our ideas down to only two ideas by week 5.  Week four we scheduled a meeting with Texas Heart Institute (THI) at the downtown medical center. This meeting was very helpful because we were able to eliminate many ideas and we narrowed down our ideas to 3.
