During the week further work was done to elaborate and expand the remaining project ideas. This includes existing technology, proposed budgets, and estimated timelines. We also spent a good deal of time brainstorming additional ideas to research and develop and eliminated those which seemed unfit for the project requirements. A template for the project timeline was created using Google Sheets.
Adaptive Membrane Absorber Budget Total: ~$448
Face Tracking Boom Mic Budget Total: ~$192
Our team was in contact daily throughout the week discussing our individual research that we conducted in Active Noise Control, Sonar, Electrodialysis, Smoke/Fire and Gas sensors, and Wave Energy Converters.
Wave Energy Conversion research showed testing requirements to be too cumbersome. Building a wave pool is beyond our capabilities and budget.

An example of existing technology for the Adaptive Membrane Absorber.
Pictured is a passive membrane absorber and its absorption coefficients for a range of low frequencies.
An example of existing technology for the Face Tracking Boom Mic
Most boom operation is done with a simple extendable pole.
The proposed design will allow for fine adjustment/target locking of the mic tilt and rotation.
John also put together preliminary timelines for each of these proposals

(Week 2) Continued Research:
Research was conducted for the Automated Pet Door Opener to present for this week’s proposal.
There are many factors that still need to be considered, including the speed and time it takes for the automatic door to open and close so the owners pet doesn't get scared and to prevent injury to the pet if.
Looking into different ways of making sure unwanted animals do not enter by using deterrents/alarms. Also, thinking of ways to make the controller have the smallest foot print possible so it is compact and easy to carry. Source 1

For the Automated Pet Door Opener more research was involved in the decision of implementing RFID or Bluetooth for the detecting the pets distance from the door, which would be tagged on its collar.
After our meeting with Professor Notash, he explained how this design seems to be more like a 5 month long project and that it needs to be more complex to be an 8 month long project for approval. Adding to the design may have some potential, but our team decided to move forward and stay focused on the absorber and boom mic projects, while also working on new ideas that we are more interested in.
Block and Flow Chart for the Automated Pet Door Opener:
The tired driver detector/alarm idea was started but not finished at the time of our meeting. Fortunately, this idea was mentioned during this week’s meeting with Professor Notash (on Thursday 9/2) and the idea was denied before completing the proposal (saving time). Professor Notash informed us that this design seemed like it might be too challenging since a previous design team attempted a hands free door using RFID, which was heavily programmed based making it complex since our degree concentration is mostly electrical engineering technology.

The link below was one of the more important sources found when conducting research for this design. This link is to Tereza Soukupová and Jan Čech’s research paper on “Real-Time Eye Blink Detection using Facial Landmarks”. Although informational, it also reveals the amount of coding that is involved.
No longer working on this design
