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 fall detection and alert system and associated methods are described. The system includes a right footwear item and a left footwear item, each of which includes foot pressure sensors, communications circuitry configured to transmit foot pressure signals from the pressure sensors to a mobile device, such as a smartphone, and a power source. The system also includes an application for the mobile device that causes the mobile device to receive transmitted foot pressure signals from the communications circuitry of the footwear, analyze the foot pressure signals to determine whether a wearer of the footwear items has fallen, display a warning if it is determined that the wearer of the footwear items has fallen, along with an option to cancel the warning, and send a signal to a caregiver if the warning has not been canceled within a predetermined period of time.

A system and method for optimizing a rescue operation of an individual. The method comprises maintaining, by an individual engaged in an activity, an unmanned aerial vehicle (UAV) associated with and in proximity to the individual. For storage at the UAV, the individual records at a recording device a message. A sensor device is configured to detect a situation requiring a need to rescue the individual at a current location, and generates a trigger signal in response to a detection. In response to the receipt of the trigger signal, a current GPS location of the individual is recorded and a launching of the UAV to traverse a flight-path to a destination location. At or before arriving at the destination location, the UAV contemporaneously provides the stored recorded message and current GPS location of the individual to an emergency response authority to inform of the individual's situation and location.

An emergency breathing apparatus for use in case of burial by an avalanche is described. The breathing apparatus may include a telescoping body configured to transition between a collapsed and extended configuration. The body may include a plurality of tubular members. The breathing apparatus may include a breathing port on one end of the device, a plurality of apertures on the opposite end of the device, and an internal lumen that fluidly connects the breathing port with the plurality of apertures. The breathing apparatus may include a spring assembly, a motorized extension mechanism, a pneumatic extension mechanism, or a combination of these devices, that are configured to extend the body from a collapsed configuration to an extended configuration.

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.

A snow burial survival mask has an exhaust tube connected to a headgear. An intake port of the exhaust tube is positioned adjacent to a breathing portion of the headgear in order to intake exhaled carbon dioxide (CO2)-rich air. An air pump connected to the exhaust tube pump the exhaled air from the intake port to an exhaust port away from the user's face, extending survival time in a snow burial situation. At least one burial detection sensor such as a motion sensor, light sensor and/or CO2 sensor is configured to activate the air pump based on detection of a burial event.
