RECOVERY ASSISTANCE DEVICE, METHOD AND SYSTEM
First Claim
1. A recovery assistance device comprising:
- a signal processing unit of a type defined to perform one or more of transmit or receive a carrier signal of a waveform and a frequency band selected to allow measurement of propagation distances to other signal processing units of the type through a material in a non-gaseous state;
a logical unit configured to combine a first propagation distance between the signal processing unit and a first another signal processing unit with a position of one of the signal processing unit or the first another signal processing unit to determine a first area of recovery of one of the signal processing unit or a first another signal processing unit;
wherein the logical unit is further configured to calculate a position of said recovery assistance device from one or more combinations of an absolute position of another recovery assistance device and a distance between said recovery assistance device and said another recovery assistance device.

Abstract
The invention discloses a recovery assistance device for helping in rescuing victims of avalanches, earthquakes or boat capsizes. The device is capable of calculating a position from combinations of a previous position and distances to other devices. Different configurations are possible, with a basic configuration consisting of a smart phone having waveform generation capabilities, processing and GNSS receiving capabilities. The device is programmed to be used in a defined mission by an application. The device can also receive a number of add-ons as a battery add-on, a modem add-on, a sound wave generation add-on, antennas, and protection, possibly waterproof, if adequate. Devices of the same type can be carried by people to be rescued and rescuers. The device is therefore quite versatile and can increase significantly the efficiency of rescue teams in different use case scenarios.

18. A recovery assistance method comprising:
-
One or more of transmitting or receiving at a signal processing unit a type of carrier signal of a waveform and a frequency band selected to allow measurement of propagation distances to other signal processing units of the type through a material in a non-gaseous state; Combining a first propagation distance between the signal processing unit and a first another signal processing unit with a position of one of the signal processing unit or the first another signal processing unit to determine a first area of recovery of one of the signal processing unit or a first another signal processing unit; wherein the combining comprises calculating a position of said signal processing unit from one or more combinations of an absolute position of the first another signal processing unit and a distance between said signal processing unit and said first another signal processing unit.
