RAS Demo
The RAS Demo passes image data captured by platform-independent, exportable JAVA in real time from an Intel camera. The image data is passed from the EMT machine to the MD machine in clips; the EMT can select any image from the running stream and send it to the MD. The MD can refresh the image at his discretion - a voice channel will run in parallel with the image data using a seperate phone unit. (This adds robustness in case of worst-case network problems.) The EMT can thus alert the MD to a new, more relevant image, or the MD can refresh the image for himself.The MD can make alterations to the image using the Java software, drawing highlighting lines around key components of the image and sending it back to the EMT. In this way the EMT is able to provide current information to the MD, who is able to provide critical assistance to the EMT in an emergency situation.
Remote Assessment System Overview
The RAS utilizes four seperate network infrastructures to relay image and other data from the field to the Doctor in his office:
1) The first of these is the PAN (Personal Area Network) which sends data from the EMT in the field to a broadcast unit housed in the on-scene ambulance. This added robustness assures that no matter where you are, the data is sure to reach its destination safely.
2) The second is the cellular network, the coverage for which is growing daily. In the event of an emergency outside of cellular phone network coverage, backup systems can use satellite relay to assure the image data reaches its end target.
3) The third network infrastructure is the network via encrypted data packets for added security.
4) The final network is a local LAN between the Doctor and his NOC (Network Operating Center) where the data is stored, indexed, and made referencible.
