PULSE firmware

PULSE Firmware with two user profiles [Basic / Advanced]

The PULSE firmware implements the following functions in addition to the existing basic functions of the previous firmware versions, which remain unchanged.

PULSE Firmware 4.0

  • Barryvox Intelligent Search (Guided fine search)
  • Expanded first signal display 
  • Optimized direction display 

Guided fine search 


The guided, audio-supported fine search simplifies pinpointing during fine searches by using an arrow. This clearly shows on the display the direction to walk in, based on the distance to and signal information regarding the buried subjects. The device helps users by means of information regarding when to change search direction and the optimum transition from fine searching in a cross (bracketing) to probing (pinpointing).

The starting point for guided fine searching dynamically adapts to the depth of the avalanche and the device guides you based on the remaining distance to the buried subject using one or more processes of fine searching in a cross (bracketing).

Display information for guided fine searching

Longitudinal axis guidance for fine searching in a cross (bracketing) 

 

Longitudinal axis direction display

 

Longitudinal axis direction display appears if the point of change in direction to the transverse axis cannot be clearly defined on the first pass. 

 

Repeat the search on the longitudinal axis at a reduced speed and make sure that you guide the device directly along the snow surface.

Transverse axis guidance for fine searching in a cross (bracketing)

 

Transverse axis direction display 

Transverse axis direction display appears if the point of change in direction to pinpointing (probing) cannot be clearly defined on the first pass. 

 

Repeat the search on the transverse axis at a reduced speed and make sure that you guide the device directly along the snow surface.

Probe indication


Displays change of search phase from fine search to pinpointing with the probe pole. 

 

When in search mode, stow the avalanche transceiver on your person so that both hands are free for probing.


If guided fine searching in a cross (bracketing) does not prove successful within a predefined time the pinpointing cross will be displayed. Determine the point displaying the shortest distance by systematic manual fine searching in a cross (bracketing), directly on the snow surface. 

 

In this scenario the probe indication is not displayed. For this reason you should implement a probing spiral process.

Expanded first signal display
The expanded first signal display allows users to transition from signal search to coarse search earlier, which reduces both the area to be searched and the time spent searching on the avalanche site. 

Optimized direction display
Thanks to the optimized direction display, the search arrow on the PULSE Barryvox® display is updated even more quickly using the integrated digital compass. This results in perfect direction indications and optimum directional guidance. 

PULSE Firmware with two user profiles [Basic / Advanced] 

The PULSE firmware implements the following functions in addition to the existing basic functions of the firmware 3.0, which remain unchanged. 

PULSE Firmware 3.2

  • Acoustic search guidance
  • Rescue-SEND
  • Lithium battery mode
  • LCD contrast setting

Acoustic search guidance 
Acoustic search guidance assists the user during the search phase by means of a patented tone sequence that increases in volume and frequency depending on the distance and direction from the buried device. 

Rescue-SEND 
As a NEW feature, rescuers who are not involved in the active search can now set their device to “sleep mode”.
 
When “Rescue-SEND” mode is activated, the device does not transmit any 457 kHz signal and therefore does not disturb the searchers on the avalanche deposit – if no movement is detected after 4 minutes by the movement sensor, the device automatically switches back to “Send” mode. 

For helpers who are not working in “SEARCH” mode with their device, in the event of a subsequent avalanche, the “Rescue-SEND” function ensures that the device transmits again and the victims can be located. 

LCD contrast setting 
This allows the user to adjust the device display to the prevailing light conditions in the area. 

Lithium battery mode 
The PULSE firmware now allows you to use lithium batteries as the energy source in the PULSE Barryvox. Lithium batteries discharge better at low temperatures and have a longer battery life.
