Philips Respironics System One (60 Series) signals

Post by charbelabinasr » Tue Oct 28, 2014 4:17 am

dear sirs,
I am a biomedical engineer student , and i am working on my final year project . My final year project is for processing treatment for the signal that get out from the system one 60 series cpap A-flex. So, i am facing a problem that is how could i read the files from the sd card in order to do a pre processing treatment for the signals that give us the cpap.

You have five choices:

1. Contact Respironics and explain what you are doing and request file structure information.
2. Download the source code for SleepyHead and use the code to construct your own file structure.
3. Get a copy of SleepyHead and run the reports to see if they will be adequate for your use.
4. Get a copy of Encore and run reports to see if they are adequate for your study
5. Get the data files and construct your own file structure.

What is the "processing treatment for the signal that get out from the system one 60 series cpap"? What signal are you looking for? What do you mean by processing treatment?

I have a feeling this student is NOT in the U.S., English is not their "first language" and may be trying to reverse-engineer the firmware in the machines.......maybe for another company outside the U.S.
Just a hunch.

If he can reverse-engineer the firmware, then good for him. Maybe we can get some decent software to mess with the insurance companies that require compliance. Might even be able to get the machines to save data like they should. Yes I am referring to the system one 60 series. Why do they make the machine erase recorded waveform data after 2 days. You got 2gig data cards that could hold a years data easily. Do you really think Phillips is going to give information on the data structure of the SD card? No way. You have to pay for it and sign legal agreements.

Dear All ,
I am a student in USEK in Lebanon , Beirut . For my project , all my problem is in how could i read the data from the SD card of the cpap it seems that the files has a format:
' .UDF ' and that refers to universal disk format as international standards but i am not able to read them in order to begin with my pre processing treatment that contains: feature extraction , windowing , noise reduction .....
so any help ??????????
I will try to contact respironics JDS74
But i need some hints if anyone can help cause i don't have much time
thank you

Respironics System One Series 50 an 60 both record wave data and keep it for a very long time. I'm not sure how many days of data get saved but it exceeds a year.

The apparent limitation on wave data stem from a limitation of the Encore series of software that won't load more than one day's wave data. It will load only the most recent data and ignores the rest (wave data only)

On the other hand, Jedimark seems to have agreed that this limitation is dumb so sleepyHead loads all of the data it finds into the database and allows access to all of it.

Hey charbelabinasr,
Do you have a machine? If you do what's the model number of it? Are you willing to operate on it?

What is you electronics capablility?
These machines use microcontrollers that you can get the data on and the development software for.
You can dump the machines memory and try to put it into the development software.
At that point you can try to reverse engineer the software.
Do you have these electronics/computer skills?

You say your a biomedical engineer student.
Can you do engineering/programming with microcontrollers?
Would you be willing to do videos showing what your doing and put them on a file storage site( mega.co.nz )as you reverse engineer the software in english?

hey borgready
yes i have the capability to do electronics and work on micro controllers and i have programming background some java language and c++
i was willing to work PHILIPS RESPIRONICS SYSTEM ONE (60 SERIES) A-Flex and i am getting some purchasing offers for that
so any help with the development software or for the micro controllers ??
thank you

hey charbelabinasr,
Do you have a machine you can tear apart. Lets see some photos of it.

If you have the machine, then tear it apart. See what micocontroller is on the board. google it and pull up the documentation for the microcontroller. I am sure they have development software that will allow you to dump the memory of the micocontroller. Do you have any good hi resolution photos of the PC board yet.

viewtopic/t101692/viewtopic.php?f=1&t=9 ... 42#p872812

This guy had torn his machine down a photographed it. Those photos are gone now. There are some other posts of photo of the device used to interface the machine for programming it. You can look at that if you want. You can buy one for about $200 USD. Any way this guy wanted to know what the error codes for the machine was.

Are you working on this with other people or are you a one man operation? How much expert reverse engineering advice can you get access to?

What type of equipment do you have access to at your university? Do you have a good electronics lab, machine tools, or what?

What's you budget for the project?

PM me your email. Do you speak and write english? I hope your not using translator software.

I would like to know more about what information your trying to access. Make a video and put it on youtube and put the link on here.
Are you trying to do what the sleepyhead software does when it reads the data off the SD card?
If that's the case just look at the source code for sleepyhead and contact the guy that made it. He can give advice on the data format respironics is using. Maybe you will get lucky and phillips will give you the data structure of the SD card for all of their machines. Any luck on contacting respironics yet?
