Survival chance optimized search strip width in avalanche rescue

Electromagnetic Interference of Avalanche Transceivers with Cardiac Pacemakers and Implantable Cardioverter Defibrillators

“…Moreover, the average pulse duration of the Ortovox f1 is significantly longer than that of more modern devices (Table ) . With respect to the transmitted field strength, all avalanche transceivers operate at the maximum limit of 7 dBμA/m in order to achieve a maximum range, although there may be considerable fluctuations in field strength . Whether the high incidence of interference associated with the Ortovox f1 was a consequence of longer pulse periods or pronounced variations in transmission frequency and field strength could not be clarified with the chosen study design.…”

A deep insight into avalanche transceivers for optimizing rescue

“…Researchers have attempted to bring greater depth to the classical method improving the search. For example, Genswein et al (2009) proposed the optimization of the search strip width to minimize the search duration and Edgerly (2002) suggested a new fine search technique for solving deep burials. New search strategies based on the incorporation of a GPS receiver and new processing algorithms have also been proposed Piniés and Tardós (2006).…”

“…However, to date, avalanche rescue transceivers are the only technology that allows a fast and reliable search of completely buried victims by their companions (Genswein et al, 2009;Schweizer and Krüsi, 2003). The device can operate both as transmitter and receiver using solenoid antennas with ferrite cores as transceivers.…”

A concept for optimizing avalanche rescue strategies using a Monte Carlo simulation approach

“…A first technical attempt to apply numerical simulations based on the Monte Carlo principle on an avalanche accident scenario was presented by Genswein et al . [ 5 ]. They optimized the search strip width for signal search with an avalanche transceiver, i.e.…”
