Closure

So, today is basically the final day of the project for this period. Hopefully it will be continued next period. 20 weeks ago we set out to create a product and we had planned to finish it by now. Due to some circumstances we haven’t quite completed our goals. The temperature sensor was ordered, only it was delivered after weeks instead of the estimated days. That made sure the temperature sensor wasn’t completely done.
Basically everything was going very smooth until the symposium on the 8th of May, and after that thing got kind of hang up and progress slowed down. There was still work getting done, only no pressure to get it done.
The shirt we had on the 8th of May is still there, only focus shifted to fine tuning the sensors and everything around it. The DPA is finished and so are the reports. Those we handed over yesterday.
In a couple of hours, the final presentations take place here in Assen, and after that we are done.

Like I said, I’m hoping the project can and will be continued next period, because this project had a lot of potential.

Update

It's been a bit quite here the last time, sorry for that. In the last few weeks we were busy perfecting the sensors. Especially Ronald and Erwin were working on this. Erwin is focussing on the temperature sensor. He has ordered a new one, which wasn’t as accurate as we had hoped, so he had to order yet an other new one. Right now he is calibrating it for our propose. Ronald is working with Dennis (from the Swimsor) to figure out a device called the DSP. This device is meant to stabilise the breath sensor results. Right now the readings change radically when you move, causing a very imperfect and unreliable result. In the mean time Henk and I both designed a G.U.I. for the D.P.A. (Digital Personal Assistant, also know as the ‘iPod application’). We made it into a little competition between us, so we would have a bit of a challenge to get the best possible result. This week we’ll see the result of that. Also we’re looking into carbon fibre pads. We have a sheet of very flexible carbon fibre, and the aim is to use that as the heart sensor. The original heart sensor was dismantled to see how it ticks, and thanks to that info we’ll now evolve that into our own carbon fibre heart sensor design. We’re still working on that as I type this.

This period has about 4-5 weeks to go till the end, and the temperature and heart sensor will probably be finished by then. The breath sensor might be a different story because of the complexity of the DSP.

Symposium

On friday, the 8th of May, the Marina de Wolfcentrum from Ermelo had their symposium, and we send Henk there to show our current status. As you can see on the pictures below, he is showing the shirt (with the heartrate and breathing sensor installed) to the crowd.





The crowd was very enthousiastic, and confident for the future.

Reinforcements II

After Marijn left us at the end of the previous week, we now have two new guys to replace him.

Ronald Reitsema and Erwin Hof have joind the team and will take care of the ICT work within the project. 

The started with everything Marijn created and read the documents we made.

After only three days they had the hartrate on screen and Herman (from the Hartfalen project) is working on the sensor-hardware. The breath sensor and temperature sensor are taking shape and both are showing results on the oscilator. We are confident now we can show things during the symposium of the Marina the Wolfcentrum on may 8th.

The heart sensor is also working, and is integrated in the shirt:

On the picture the sensor is next to the shirt for demonstration purposes. 

Like said earlier, the breath sensor is also comming together:

Next week is a holiday, so there won't be much news.

The end of Marijn's Minor

Hey all,

It is almost a month ago that we posted, that's because we were very busy!

We went to 2 events :
- Zorg & ICT Beurs
- Noodpakket voor IT'ers congres

Which have really inspired us. We really had a nice time meeting new people and doing some work.

I made a Desktop Application which is able to show the measurments of the sensors.

Now my time is over and it's time that someone else takes the ICT work in this project.
I'm sorry that I have not posted in a while. My source and documents will be released later by the next group when we have a complete product.

Cheers!

Marijn

Time flies

...when you're busy. We spend this week on further developing the software, and worked on documentating the comming research process.

In the beginning of the week we presented our current situation to the other CENSI projects, and they presented their status as well. It was a very interesting day. Also this week, we paid a visit to the Marina de Wolfcentrum in Ermelo. Wich was interesting aswell. Also, the people in Ermelo had some feedback on the PvA, wich will be implemented into it.

Busy Bees

Hey All,

We are sorry that we have not updated out blog for a while now.

We are currently very busy with the research and realisation of our product.

Sensors and hardware.

I have worked on the Polar Heart Rate sensor, which I did some tests with on our collegue Henk.

I have some graphs of those tests and I will try to upload them a.s.a.p.

Furthermore, we have arranged a bluetooth module that works with our SunSPOT (BlueSmirf Bluetooth Gold from Sparkfun). It enables us to warn the client on their mobile phone via bluetooth.

Planning.

As I already said, we are very busy with HdH and try our best to deliver a proof-of-concept product by week 10.

So, I hope to give you all a new heads-up soon.

Cheers,

Marijn, IT Student

Here's the chart!

Reinforcements

On thursday we met the two health care students who are joining the project, Ilona Wind and Tsjitsjo Vlieger. They were in Assen on wednesday already, but Marijn and I were both in Groningen at the time.
During the meeting everyone was introduced to each other.
A few days earlier Henk (Hartfalen project) and I looked over the possibilities of the harness to wear the sensor device. We used the designs from the previous teams, and our own thoughts to create a couple of other designs. One of the original designs had a single band around the chest, but we were concerned about the comfort while wearing it and weather it wouldn't leave it's position sinking down.

Two of our designs are a sort of harness, the 'chest-band' plus pieces over the shoulders, while the third is a complete shirt without sleeves. The shirt design is tested concept, a couple of companies created a shirt with sensores into the material of the shirt. An other interesting thing we saw (although it's not very relevant for the project) is Philips LumaLive. Textile combined with LED's to create interactive t-shirts. Sensores could be combined with textile in a simular way. The three designs are included beneath.

On wednesday the Plan van Aanpak was almost done. The content is mosly done, now it's a matter of checking for errors and performing a spellingcheck.

Combined forces

This week we combined forces with the 'Hartfalen en revalidatie' project, because there are a lot of simularities between both projects. In the beginning of the week we had a brainstorm session in Groningen to get the right mindset, and make sure everyone understood the current situation, and the previous projects. It turned out that we all had the same mindset all along, but we just weren't on the same page. 

Later this week we created a planning for the Plan van Aanpak. The Hartfalen guys worked with us here again to make sure we were on the same page again. It took about an hour to get it done, but now we have a pretty solid planning for the first 10 weeks. After 7 or 8 weeks we'll create the planning for the weeks 11-20. This way it is easier for the 'replacements' of Marijn en Herman (Hartfalen), and of we don't meet our objective the first 10 weeks, it's easier to adjust the planning for the second period.

The progress on the PvA is going steadily now, and it's supposed to be finished wednesday next week. That shoudn't be a problem.

Meanwhile, Marijn has been experimenting with the SunSPOT's. They are starting to do what he want's them to do. For now he is making some basic pograms to understand it better while I focus on the documentation. His program currently is based on the Structuur in de dag project, but the device plus the programming language are excactly the same as for Herken de Herhaling. 

The healthcare students we mentioned earlier are probably joining us at the end of next week. 

Where to find our files.

Hello everybody,

I have set-up a Sourceforge page for this project. (LINK)
This enables us to keep our code, documentation, forums, etc. all in one place, and makes it easier for other groups or people to get involved.
This blog will still be updated to get the story behind it all, offcourse.
Sourceforge makes it possible for "outsiders" to download code, documentation and join the project as well.


SVN
We do not only to post all our our code, agenda's and minutes on the blog, but on our public SVN- Repository that comes with Sourceforge as well.
The svn link to this project is : https://reconrep.svn.sourceforge.net/svnroot/reconrep

Please use a Subversion client like TortoiseSVN : HERE , to access the Repository previous mentioned.

Don't know how SVN works? Don't worry. Here is quick 10minute (max) tutorial for using TortoiseSVN (NOTE : fill in the link mentioned earlier instead of the one in this turotial):
http://www.mind.ilstu.edu/research/robots/iris4/developers/svntutorial/


That's all for now,

Marijn


P.S: For the groupmembers that want to make changes or post files:

Those that do not have an sourceforge.net acount, please contact me for a general censi account.

Getting started

This week we started the 'Herken de Herhaling' project (see post 'Welcome'). On monday we attended the kick off in Assen and received data from the previous group. 

The rest of the week was spent going trough the data, and creating a todo list, which will be used as a backbone for the PvA.

Thursdag we had a meeting with Jan Erik van Deijnen in Assen. After this we also received the data from the 'Hartfalen en revalidatie' project because there are a lot of points where the projects have a connection. The next day we had a meeting with Bryan Williams, he wasn't able to make the thursday meeting. Today we also started setting up a video connection to Groningen, to be able to have contact with al of the students at both locations.

With both the meetings behind us, we have a better picture of the project, and next week we'll work on the PvA.

Welcome!

Welcome to the new blog of "Herken de herhaling!"

We are the new project group for this project. At this moment this project is run by the folowing students:

• Marijn Oosterveld (Informatica)
  
• Jasper Venema (Human Technology)

Marijn will be a part of the project for 10 weeks, while Jasper will do 20 weeks.

In the next few weeks a couple of heathcare students will join the project. As soon as they do, you'll read it here.

Here's some starting information:
