A method for alerting a user of a wearable airbag system. The method includes the steps of ensuring that the airbag system is active, checking the current location of the airbag system, calling a server storing a plurality of locations, each location being associated with an increased risk for an accident, and if the current location of the airbag system is close to a stored location, further performing a step of alerting the user.

A jammer system includes a jammer unit, a valve coupled to the jammer unit, and a sensor coupled to the valve. The jammer unit includes a jammer media and a membrane including an inlet. The membrane is configured to surround the jammer media. The valve is configured to allow a fluid to pass through the inlet of the membrane. The sensor is configured to cause actuation of the valve to evacuate the fluid from an interior of the membrane. The evacuation of the fluid from the interior of the membrane results in stiffening of the jammer media within the membrane.

The present invention relates to a wearable protection device (10 comprising:—a protective helmet (12), provided with at least one first inflatable chamber (14); said at least one first inflatable chamber (14) being suitable for moving between a rest condition, wherein it is in a deflated status, and an operating condition, wherein it is in an inflated status;—a wearable element (16) comprising an inflator unit (18) and an activation system (20); the activation system (20) being designed to trigger the inflator unit (18) if a danger situation for the user of the wearable protection device (10) is identified. According to the invention, the wearable element (16) comprises at least one second inflatable chamber (26) suitable for moving between a rest condition, wherein it is in a deflated status, and an operating condition, wherein it is in an inflated status. The inflator unit (18) is connected to said at least one first inflatable chamber (14) and/or to said at least one second inflatable chamber (26). The inflator unit (18) is designed to inflate said at least one first inflatable chamber (14) and/or said at least one second inflatable chamber (26) so as to move said at least one first inflatable chamber (14) and/or said at least one second inflatable chamber (26) in the operating condition when a danger situation for the user of the wearable protection device (10) is identified by the activation system (20).

The present invention is a helmet system that reduces concussions by damping rotational force transmitted to a helmet user. The helmet has an helmet shell that moves independently from an internal body worn by the user. At least one magnetic force emitter on the helmet shell's interior directs at least one interior-facing magnetic flux axially at the internal body. At least one magnetic force emitter attached to the internal body directs at least one exterior-facing magnetic flux at the at least one interior-facing magnetic flux. In a resting state magnetic flux interactions are limited. When a tangential impact rotates the exterior shell, the at least one interior-facing magnetic flux approaches to the side of the at least one exterior-facing magnetic flux, inducing negative torque of the internal body in a variety of ways. Rotational momentum is diffused in a variety of ways. The exterior shell is returned to the resting state in a variety of ways. A sensor may be contained on the internal body to detect magnetic flux acceleration of the exterior shell, and may store or transmit data, and may trigger an airbag around the user's neck, or reduce helmet shell motion, or return the helmet shell to the resting state.

A system for providing safety assistance in a vehicle. The system includes a helmet and a first plurality of sensors in the helmet. The system further includes control circuitry that captures a first plurality of signals from the first plurality of sensors in the helmet. The first plurality of signals indicates first motion information corresponding to the helmet. The control circuitry further controls one of an inflation element or a hardening element disposed in a wearable garment based on a determination that the first motion information corresponding to the helmet exceeds a first predefined threshold.

Systems, methods, and devices for protecting a user head are provided. In one example, a computer-implemented method can comprise receiving, by a processor operatively coupled to a helmet device, helmet data comprising at least one of statistical data, statistical models, or natural intelligence algorithms. The computer-implemented method can also comprise inflating, by a gas delivery system of the helmet device, a pressure chamber element of the helmet device based on the helmet data. Furthermore, the computer-implemented method can comprise scanning, by a sensor system of the helmet device, surrounding environments of the helmet device for object data.

The present invention is a helmet system that reduces concussions by damping rotational force transmitted to a helmet user. The helmet has an exterior shell and an internal body that moves independently from the exterior shell. At least one magnetic source on the exterior shell's interior has a dipole directed axially at the internal body. At least one magnetic source on the internal body has a dipole aligned with the same axis, directed at the exterior shell. In a resting state magnetic sources generate a weak magnetic field. When an impact rotates the exterior shell, it moves off the initial alignment and closer to the internal body. The previously aligned magnetic sources torque. The magnetic source on the internal body torques in the opposite direction of the rotation, as do all initially aligned magnetic sources impacted. Angular momentum is displaced, diffused, offset, damping rotational force transmitted to a helmet user.

The emergency protective helmet includes a storage support worn about the neck, a series of curved elements mounted movable in rotation with the storage support worn about the neck and with each other at their ends so as to be able to switch between a first, functional deployed position, in which the curved elements form a protective structure, and a second, non-functional stowed position, in which the curved elements are housed in the storage support worn about the neck, the emergency protective helmet further including a compressed gas cartridge and a set of flexible tubes fluidically connected to the cartridge and connecting the curved elements to each other, the flexible tubes being arranged such that inflating the flexible tubes switches the curved elements from the second, stowed position to the first, deployed position.
