Hi Vasanth,

Please try version 0.6.2. We've corrected a minor bug with a major impact that we think caused this error. Sorry for the inconvenience and time delays. Let me know if the new version works.

What does an EventLoop do?

10 years ago • updated by 10 years ago • 3

As I've been reading DeviceListModelImp.java and related classes, in an attempt to duplicate the OpenICE Supervisor's behavior around detecting devices going on and off.

I've come across the class EventLoop, that I assume has something to do with managing Topic events. The code suggests it has to do with managing the running of multiple snippets of DDS-related code.

What is EventLoop's purpose? Would its purpose likely become clear if I learned more about DDS?

Thanks,
Brad

IVY 450C Device Time of 0?

9 years ago in OpenICE • updated by 9 years ago • 2

We're using an IVY 450C Multiparameter Monitor, with a Device Adapter running on an Intel Edison. Any ideas why the Device Time reported for, for example, heart rate is 0 (the Epoch)?

The Monitor is connected to a Patient Simulator, and is reporting heart rate and blood pressure that look good, except that Device Time for all its values is reported as 0.

On a likely-related note, the OpenICE Supervisor shows what looks like a time-sync warning for the Multiparameter Monitor (and our other devices). Any idea what's going on here? What is required for a Device Adapter to properly time-sync?

Thanks,
Brad

Hi Dennis,
I’m sorry that the recent change broke the code for you and I greatly appreciate your reporting it and even including a patch. In our lab we’re still working on a really flexible deployment strategy for our ‘fleet’ of beaglebones. I added the /etc/issue as a quick way to see which had been upgraded to 14.04LTS. I should have done more research on the /etc/issue file in general before including it. I know a lot of folks at NIST who use CentOS, is that the distro you are using?

If I understand correctly what broke down was the lengthy string … probably throwing an exception in the CdrOutputStream? I’m really not thrilled about RTI’s API support for java programmers. On the plus side they have bound their underlying CDR (common data representation) libraries to java which is great. It means I can generate types natively in java (other implementations such as OpenDDS require types be generated in C++ first; then a JNI binding library is built specifically for those types … which is a multi-platform deployment nightmare). But on the other hand they do not support the standard java DDS API (I believe they plan to in the future) So as you can see the one adjustment I made to your patch was to jump some hurdles to avoid hardcoding the length (128). It would be nicer in java if they annotated max lengths in a way that facilitated validation. The commit in SourceForge git viewer:
http://sourceforge.net/p/mdpnp/code/ci/5757b04fabe6c870e748e7922a8573cc45a152b3/

If you wouldn’t mind I’d love to hear more about how you are using the code. Should I expedite a new release for you or are you building from source? If I know your particular areas of interest I can try to involve you in relevant discussions about how OpenICE should evolve. Also if you have issues or comments we’ve set up a website at http://community.openice.info that you can use in the future.

Thanks again,
Jeff

Simple OpenICE Setup

9 years ago in OpenICE • updated 9 years ago • 2

Hello,

I have a question regarding how to connect using the Simple OpenICE Setup.

In the diagram for the Simple OpenIce setup here (https://www.openice.info/docs/6_example-setups.html), You have a MP70 directly connected to the computer via RJ45 -> DB9 -> USB. This makes sense, but upon opening OpenIce and selecting the Intellivue/Serial option, it prompts me for a network address.

I'm a bit unclear as to what I should be inputting for a network address when connecting via serial, could someone elaborate?

Thanks very much!

Jeremy

hello, I'm looking into this community as a noob to the EMR, EHR, MD PnP, Payer, Provider etc. There is a lot to wrap my head around.

My questions are more related to how you are interfacing with EMRs, and what format you're pushing that data? From a more technical perspective, are you exposing the data through an API? Or are you publishing that data directly to a system? Would love to get a quick overview, from a quasi-technical perspective.

Thanks.

Hi JD,

Thanks for your question! The short answer is that EMR communication/integration is done through HL7 (http://www.hl7.org/). Our preferred HL7 version is the development version of HL7 FHIR (http://hl7-fhir.github.io/). If you're interested in using HL7 FHIR and java (what OpenICE uses), a fantastic learning resource is the HAPI FHIR project (http://jamesagnew.github.io/hapi-fhir/).

We have only begun to experiment with EMR integrations, but our current state is best illustrated by the OpenICE Supervisor app 'HL7 Exporter'. You can use the app by installing OpenICE: http://mdpnp.sourceforge.net/. And you can check out the code here: https://sourceforge.net/p/mdpnp/code/ci/master/tree/interop-lab/demo-apps/src/main/java/org/mdpnp/apps/testapp/hl7/. The app will take data from the active patient and export it via HL7 at a user defined time interval.

Our HIMSS15 demo app illustrated some mock "auto-validation" of medical device data that was then exported using the HL7 export app to a fake EMR. That system is representative of some of our future development ideas that will be on our roadmap eventually. For now, there is still a lot of work to do in this area...

Feel free to continue the conversation. Thanks,
Jeff

Confused about the communication between two computers both running openice

10 years ago in OpenICE • updated by 9 years ago • 7

hi,
I am new to this community.I was doing some experiment in openice.Recently i found an interesting problem.When i ran the newest version openice on two computers in the same network,especially,i ran "ICE_Supervisor" on computer A,and ran a simulated device through "ICE_Device_Interface" on computer B.What i found is that the simulated device did not show in the supervisor in computer A .But i remember it's not the case like this in the older version openice.Does not a supervisor can recognize a device in the same network not only in the local computer? So i got confused and need help. Thank you very much.

How to build OpenICE source on BBB

10 years ago in OpenICE • updated by 10 years ago • 22

Hi, guys!

I was installed Revision C Disk Image and gradle-2.4 and sync to a NTP clock on BBB.
but, jdk 8u33 in Rev.C disk image is not build OpenICE source on BBB. (./gradlew)
The reason is 8u33 is not supported JavaFx. so I reinstalled jdk 8u6.
but OpenICE source is not build on BBB....
I want to build OpenICE source on BBB.
help me how to build OpenICE source on BBB or build reference.

p.s - Your device adapter(BBB) have a rs-232 serial port. my BBB don't have a serial port. T.T

thanks

Reading a DeviceIdentity that has a blank model field

10 years ago in OpenICE • updated by 10 years ago • 6

I'm writing an OpenICE app designed to report the on/off state of various Devices. So far I've successfully modified Hello OpenICE code to Subscribe to HeartBeat and DeviceIdentity Topics. The HeartBeat data seems to arrive fine, but the DeviceIdentity data has problems.

In the received DeviceIdentity, the model name is blank, rather than being something like "Pulse Ox (simulated)". I've seen some symptoms that suggest that the model string gets filled in later, but I'm not certain of that.

I wanted to double-check with you that I'm using the correct pattern to read the DeviceIdentity data: I substituted class names in Hello OpenICE code based on some guesswork, so something may be incorrect. Based on the symptom I'm wondering whether I'm not properly telling DDS that I want to read the data contents. I haven't found an example of reading DeviceIdentity in the mdpnp git.

Here is the relevant code (adapted from HelloICE.java) - I apologize for the formatting. Note that on reception of a Pulse Ox (simulated) DeviceIdentity, the model field is blank.

Thanks for your help,
Brad
---------------------------------

public void on_data_available(DataReader reader) {

ice.DeviceIdentitySeq deviceIdentitySeq = new ice.DeviceIdentitySeq();
SampleInfoSeq infoSeq = new SampleInfoSeq();

DeviceIdentityDataReader diReader = (DeviceIdentityDataReader) reader;

try {

diReader.read(deviceIdentitySeq, infoSeq, ResourceLimitsQosPolicy.LENGTH_UNLIMITED, SampleStateKind.NOT_READ_SAMPLE_STATE, ViewStateKind.ANY_VIEW_STATE, InstanceStateKind.ALIVE_INSTANCE_STATE);

Date now = new Date();

for(int i = 0; i < infoSeq.size(); i++) {

ice.DeviceIdentity data = (ice.DeviceIdentity) deviceIdentitySeq.get(i);
