Currently, we are in the middle of finishing our prototype and working on our final paper to accompany it. We have set the goal to be completed with our initial draft of the paper by Monday so that we can edit it and add final details throughout the week as needed. In addition, we will be taking videos and photos of our working prototype next week. In addition, we also have received data to use to test our prototype from a pregnant sheep with twins. We received this data after our meeting with Dr. Cahill, who works at BJC in maternal fetal medicine. She connected us with Yong Wang who works for her and Yong was able to connect us with this data.
We look forward to completing our project and are excited to be close to a final prototype!

4/7 Hey all,
We are continuing to find animal data to test our algorithm on. We will meet Dr. Allison Cahill on Wednesday, and we are finding a time with Cuculich's Lab to talk about our project.

3/31 Hey all
We met last week to look over our graded V&V reports. The biggest takeaway we received from the comments was to incorporate animal data into our project so we are not relying on creating an "instance" of multiple pregnancy data from two separate single pregnancies.
Matt and Grace met up earlier this week and in the spirit of achieving the above goal, we reached out to Dr. Rick Scheussler and Dr. Karen Wickline at the suggestion of Professor Yin during our last meeting. Unfortunately, both of them got back to us saying that they could not help us, but they both provided us with further leads to pursue. Dr. Karen Wickline told us to reach out to Dr. Allison Cahill and Dr. Scheussler gave us the contact details of Phil Cuculich who was working on the pregnant sheep ECGI under Dr. Rudy of the BME department. During our earlier meeting with Dr. Rudy, he had given us the contact details of Yong Wang one of his earlier PhD students who had worked on the same project. We had reached out to Yong twice earlier this year and the end of last year but have still not received a response. Moving forwards, we will try the two additional leads that were given to us. Additionally, we have selected the materials to build the recording and setup part of our prototype, and we plan to purchase them early next week.
Finally, on my end, we have finalized the ICA on the sets of single pregnancies and believe that we are making significant headway into the project. The relevant files were uploaded to google drive, a link of which is on scinote. Moving forwards on the software side, we are yet to implement a pre-processing portion of the input data, which should improve results drastically, a heart rate detection program (peaks for 5 second intervals are currently being counted by hand), and finally testing it out on a set of data that represents multiple pregnancies: hopefully we can obtain animal data, but we can fall back to our plan of combining different sets of singular pregnancies with a random weighting matrix.

3/24 Hey all,
Sorry for the late email. We received the graded reports and read through the comments. We are continuing to build our prototype and will try to reflect the comments onto our design.

3/3 Hey all,
Updates from this week! We completed our V&V report and are now working to finalize the V&V presentation that Grace will be presenting to the class next week. In addition, we are beginning to pull together our prototype for our fetal heart rate monitor. We are very excited to begin building our device and look forward to the last part of the design process. Let us know if you have any questions.
Best, Matt, Grace, and Varun
2/24 Hey all
We have finished working on our fast ICA algorithm to separate ECG data and are currently working on preprocessing to achieve better results. We will meet this weekend to start working on the V&V report and presentation.
Regards Matt, Grace and Varun
2/10 Hey all,
Our group met on Wednesday to work on the signal processing algorithm for fetal heart rate. We are also working on using power lab for real time recording of heart rates. In addition, we have contacted Yong Wang again, but still haven't gotten a reply. Other than that, those are the main updates from this week.
Best,
Matt, Varun, and Grace
1/27 Hey all,
Updates from this week. Our group met yesterday (Thursday 1/26) to discuss our thoughts for this upcoming semester, mainly the first couple of weeks. We determined that when it comes to the prototype, Grace and Matt will focus heavily on the hardware of the device while Varun will focus his efforts on the software. With our approved budget from the department, we plan on purchasing electrodes very soon, as well as beginning to access other materials that are already available in the department through Patricia's lab.
Other than that, those are the main updates from this week.
