Short-Range Wireless Audio-Video Link for Accident & Emergency Medicine.

摘要

In this paper, a wireless, simplex communication link covering a range of 100 ft (indoor) and up to 300 ft (outdoor) is presented. This link establishes a one channel color video and mono audio communication with an emergency vehicle such as an ambulance. To ensure a totally hands-free operation, a miniature camera is mounted on a modified safety helmet. The camera is fitted with a microphone. The video transmitter and supply battery are carried by a pouch tightened to the paramedical's waist. Field tests have shown that the system can reliably transmit audio and video signals from a simulated accident site to an emergency vehicle. Special emphasis has been put on using off-the-shelf available hardware components. Keywords: Telemedicine, wireless, multimedia, accident and emergency.
