The invention relates to a system for searching for a target beacon (BC) attached to an object or to a living being to be located comprising said target beacon (BC) emitting a target radio signal in an emission range (P) and a detection device (F) capable of detecting the target radio signal (SC) emitted by the target beacon (BC), and to the method for searching for the corresponding target beacon (BC).

A snow burial mask of the present disclosure comprises a burial sensor module, a processing unit, and a location tracker. The burial sensor module is configured to measure at least one indication of a snow burial. The location tracker is connected to an external device to receive a first location data and the processing unit. The processing unit is connected to the burial sensor module and configured to determine whether the snow burial has occurred based on measurements of the burial sensor module. The location tracker sends out the location data if the processing unit determines the snow burial has occurred.

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.

The invention relates to an avalanche transceiver, having a transmitting unit for transmitting at least one transmit signal, a receiving unit for receiving at least one transmit signal from at least one further avalanche transceiver, and a control device for controlling at least one loudspeaker. The control device is designed to control the at least one loudspeaker to output at least one voice message on the basis of at least one event. The at least one event is associated with a search for the at least one further avalanche transceiver. The invention further relates to a method for operating such an avalanche transceiver.

A platform-agnostic buoyancy aid includes a bladder having a direction of inflation, an inflator coupled to the bladder and configured to fill the bladder with a gas in response to actuation by a trigger, a trigger connected to the inflator and configured to actuate the inflator in response to a tension applied to a ripcord, and a removable directional attachment rig holding the bladder, inflator and trigger, the removable directional attachment rig configured to attach the buoyancy aid to at least one of a wearer's backpack, clothing or harness such that the relative angle of the direction of inflation of the bladder to the wearer's centerline remains substantially constant.

An emergency rescue equipment having a harmonic reflector circuit comprising an antenna connected to a non-linear circuit via a matching circuit and a casing that in part enclose the harmonic reflector circuit, wherein the harmonic reflector circuit is configured to receive a signal at a receive frequency (fRX), and configured to transmit said received signal at a transmit frequency (fTX), where the transmit frequency is a multiple of the receive frequency, the harmonic reflector circuit wherein the receive frequency (fRX) is in an interval from a first frequency to a second frequency, where the first frequency is at least 800 MHz; and the second frequency is at least 34 MHz larger than the first frequency; the received signal is transmitted at the transmit frequency (fTX) with an output power (Pout) of at least 70% of the maximum available output power (Pmax).

An operating handle for an avalanche rescue system, with at least one functional element, is arranged to be coupled to the at least one functional element of the avalanche rescue system. The operating handle is used to trigger the functional element. The operating handle is designed on one end as a mouthpiece or embodies such a mouthpiece. The mouthpiece of the operating handle can be coupled to a ventilation functional unit.

A buried person search device using a detachable module is disclosed. The device includes a ground drone 10 deployed at a site of a collapse disaster, the ground drone 10 having a communication device 80 and a first beacon, a camera device 40 mounted on the ground drone 10 to photograph surroundings of the ground drone 10, a storage 50 installed on the ground drone 10, a plurality of repeater modules 60 connected by a wireless communication network to relay wireless communications between the ground drone 10, a flying drone 32, and a command and control center 100, each of the repeater modules 60 having a second beacon, and a sensing device 70 installed on the ground drone 10 or the repeater modules 60 to collect a sound, wherein the storage 50 accommodates the repeater modules 60, and throws the repeater modules 60 in response to an operation signal.

A portable safety device (100) for inflating multiple envelopes includes at least one inlet for surrounding air (1), at least one inflation system, at least one enriched air or gas zone, at least one nonreturn valve (2), at least one connector (3) connected to the at least one inflatable envelope (4). The device also includes at least one separation wall (8), which compartmentalizes at least the end of at the connector (3) opening into at least two substantially hermetically independent inflatable envelopes (4).

A rescue device with a hybrid foldable avalanche airbag, the airbag containing at least one outer gas compartment that surrounds at least one inner air compartment. The outer compartment constitutes a pneumatic support frame for the airbag connected via a discharge valve with at least one pressurized gas cartridge. The inner air compartment is provided with at least one check valve through which ambient air is drawn in. The folded airbag is placed in a pocket of a backpack or in a pouch provided with shoulder straps connected to a buckled belt forming thereby a vest.
