GCRC Informatics Project Sponsor: Dr. Paul Harris, GCRC Informatics Director Members: Chris Heath, BME/EE Adam Nagel, CompE Chris Nash, EE Brendan Soar, CompE February 24, th Spring Presentation

Progress This Week Added more functionality, robustness to program Identified even more issues to address Began documentation process for Dr. Harris Implemented system on completely new components to ensure portablility Ran into problems with network connections

Added Functionality Better GUI Ensured protection of data file on PDA in case of program crash Created failsafe algorithm to deal with loss of Bluetooth connection. Fixed other issues –Exiting at certain points –Dynamically changing timing scheme –Problem with 1 st Measurement

Bluetooth Failsafe Algorithm

Documentation Created “Install” CD with all prerequisite software Went through entire process with Dr. Harris and Carlos Took screenshots, recorded action for creation of typed User’s manual Part of required deliverables to Dr. Harris at end of semester

Exported System Dr. Harris’s PC HP iPAQ Pocket PC Previously unused monitor Issues with Bluetooth on different model PDA

New Functions to Add Setup Bluetooth independently of PDA model Create “stop bp acquire” button Create other Vis –HR only acquire –Remote control Compatibility with other models Other GUI features

“Showstopping” issues with DALP Code won’t compile for Windows Mobile platform Pre-compiled DALP DLL not compatible with LabVIEW functions Difficulty learning how to use a class from a linked library Shift in focus –Developing alternative approaches to uploading data

First Alternative Use a desktop as a Bluetooth link Advantages –Involves mostly proven components –Simple server VI application due to “data dump” method Disadvantages –Requires modification of solution requirements –PDA must be returned to central location –More complex procedure for users

Second Alternative Use a desktop as an x link Advantages –In line with original solution requirements –No “data dump” or extra steps required for nurses –Real-time monitoring of study progress Disadvantages –Server VI will need to handle complex cases –Server VI will need to be running at all times

Goals for the coming week Successful interviews with ADTRAN Research MySQL connectivity alternatives –802.11x w/ network server solution –Bluetooth/AirCable pass-thru solution Bluetooth connection independent of PDA, so one PDA can connect to multiple devices Wrap up mid-semester progress report
