Project Name: At-Home Sleep Stage Monitor
Group Number: 29
Group Members: Kiron Sukesan, Matthew Hwang, Yinong Wang

Current status of project: After learning that the Risk Assessment was not due last Wednesday, we decided to postpone completion until we have formulated a complete solution.   We looked into possible devices for amplifiers and analog to digital converters.  One good solution for the ADC is the Texas Instruments ADS1298 ADC because it appears to fit all of our requirements for signal fidelity.  We also found more papers that we could use for more suggestions on the equipment. We also further researched potential electrodes and which placement pattern would be most effective.  

Work planned for next week:  We plan to start CAD modeling of possible headwear designs. In addition, we will continue finding suitable signal conditioning devices.  We also will begin considering different ways we will store the EEG data in the device.  

Anything needed from client or TA or instructor to continue work: No

Current status of project: We completed our preliminary report and presentation. The initial website was completed and can be viewed at: sleepstagemonitor.weebly.com. Examining existing solutions via literature and patent searches to develop a novel solution for occipital lobe EEG. 

Work planned for next week: We will begin formulating solutions to our problem. Complete Risk analysis assessment.

Current status of project: This week we met with a sleep study technician, Dr. Brian Toedebusch to discuss problems with sleep studies as they are and the hurdles we might have to face in the design of our device. It was suggested that we expand the capabilities of our device beyond just EEG.  We also met with Dr. Lucey and verified the scope of our project.  In addition, we met with Dr. Moran and decided that development of the mobile device application to receive the EEG data is not a primary concern, and that we should focus our efforts on developing the actual device.  We have also worked on the preliminary report and presentation for Wednesday.

Work planned for next week: Following presenting our reports this week we will begin formulating solutions to our problem.

Current status of project: We did a patent and literature search which revealed many potential designs depending on what kind of dry electrodes we use and what kind of algorithm we use for processing the data.  We also continued working on the website for our project.  
 
Work planned for next week: Visit the sleep center to talk to a technician and hopefully observe how they set up a sleep study. Complete first report and presentation.
