MDPnP
I am a member of the Medical Device Plug and Play (MDPnP) project. Our group's goal is to design a flexible software architecture for complex systems of networked medical devices in a clinical setting. We have previously mocked a system using the JavaScript programming language. A rough overview of our work from Summer 2010 can be found here. A poster that I presented during Summer 2010 can be found here. Currently, we are reimplementing the architecture using a variety of technologies, including Java, JSON, and CouchDB.
