An emergency apparatus having: a foldable shovel having: a shovel handle; a shovel head pivotally engaged with the shovel handle; a lighting apparatus associated with the shovel handle; a leveler apparatus associated with the shovel handle; and a utility slot nested within the shovel handle; and a carrying case configured to engage with the foldable shovel and secure the foldable shovel to a user. Different embodiments of the carrying case may be capable of providing additional functions, such as providing redundant lighting and leveler apparatuses, and additional storage space. The emergency apparatus is sufficiently small and lightweight to avoid encumbering the user.

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 a device and a method for determining whether a living person has been buried in collapsed ground. The device consists of a rod provided with a receiver unit and a signal processing unit. The receiver unit is intended to receive reflected radar signals transmitted from a radar transmitting antenna and transfer these signals to the signal processing unit. The signal processing unit which is provided with specific detection units determines whether the received signal have been Doppler shifted. By determining that the device can decide whether the Doppler shift depends on the moving chest of a breathing person buried alive.

The invention relates to an avalanche airbag (2), comprising a deployable outer bag (12), consisting of a flexible, gas-permeable material, and a deployable inner bag (13), consisting of a gas-tight elastic material and inflatable with gas, whereby the inner bag (13) is arranged inside the outer bag (12). The material of the inner bag (13) has an elasticity of at least 25%. The avalanche airbag (2) facilitates rapid deployment after activation over the entire temperature range as well as a small pack volume with a low total weight. Furthermore, the invention relates to a method for manufacturing an avalanche airbag (2) and an avalanche airbag system.

Disclosed in the present invention is an all-in-one ski and snowboard accessory tool as a comprehensive repair and maintenance tool set for skiers and snowboarders and other winter sports athletes. The accessory combines both physical tools and electronics in a compact and lightweight form that allows the skier or snowboarder to maintain, adjust and repair their equipment as needed. This compact accessory provides the tools to file down the edges to the desired gradient for a smoother experience and better performance. Tools to adjust bindings are also included. An avalanche transmitter as well as a LED light for emergency situations are integrated into the accessory for improved safety in dangerous situations. During use, the edges of skis or snowboards can change their gradients and become irregular. Bindings may need to be adjusted. The compact form allows the athlete to carry the accessory in normal ski gear.

A sub surface terrestrial disaster safety device comprising a housing constructed from impact-resistant materials, a pressurized colored gas cylinder containing a neon-based mixture, an oxygen cylinder, an olfactory signal cylinder, and a micro controller. The micro controller includes sensors to distinguish between normal activities and disaster conditions, initiating a triggering mechanism upon detection. The triggering mechanism activates a permeation system controlling gas flow, creating a distinct surface mark for enhanced visibility to rescuers, while simultaneously providing emergency oxygen to the user. An alternative embodiment includes a communication module emitting a rescue signal with GPS coordinates. The device represents an advancement in safety technology, combining visibility enhancement, oxygen supply, and rescue signaling in a lightweight, durable design for individuals in disaster-prone environments.
