An articulated cervical spine and neck protection system for protecting the cervical spine and the soft tissues of the neck, and for reducing related injuries including concussion. The invention has been developed primarily for use in full combat scenarios, including weapons-based combat, and combat-training scenarios, including in the defence forces, for law enforcement, or in martial arts competition or training including those involving weapons. The articulated cervical spine and neck protection system comprises an articulated cervical shroud assembly that allows good movement while protecting the cervical spine and soft tissues of the throat and neck against risks commonly associated with full contact sports and real combat scenarios, including weapons-based combat.

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.

A protective system is provided including an airbag system for protecting a body part of a user in case of an accident, including a control unit and a communication interface. The protective system further includes an external device having a communication interface. The communication interface of the airbag system is configured to communicate with the external device using wireless communication.

A helmet attachment system (5, 31) comprising a helmet (1), a net (5) arranged on the helmet (1), and a helmet attachment arrangement (31). The helmet attachment arrangement (31) has a base layer (33) and an attachment layer (35). The attachment layer (35) is attached on one face of the base layer (33). The attachment layer (35) comprises a plurality of attachment layer sections (35a) that have a mutual distance and that define a string-receiving pattern (37) configured to receive strings (9) of said net (5).

Various embodiments herein provide a hard hat with a removable light assembly. The hard hat includes an outer shell with one or more windows. The removable light assembly is removably coupled to an interior surface of the outer shell. The removable light assembly includes a support structure and one or more lights (e.g., light emitting diodes (LEDs)) coupled to the support structure and positioned behind respective windows of the one or more windows. In embodiments, the light assembly may include an arm that extends from the support structure to an underside of a brim of the outer shell. A power control element may be disposed on the end of the arm to control the one or more lights. Other embodiments may be described and claimed.

A pair of electric goggles is disclosed. The goggles include a conductive lens mounted onto a frame adapted to be electrically connected to an electric socket in order to raise the temperature of the lens, when powered. The goggles are provided with a strap for attaching to a helmet, the strap has a strap clip designed to have the electric socket attached thereto. The electric socket is meant to be electrically connected to a power supply via a power cable. With the combination of a strain relief clip located below the electric socket, the power cable can be positioned in a predetermined configuration, which unencumbers the user from the power cable when detaching or removing the goggles.

An airbag system for protecting a body part of a user in case of an accident is provided. The system including an airbag adapted for inflation upon an accident occurring during an intended activity, at least one sensor configured to measure movements of the airbag system, and thus indirect the movements of the user and a control unit configured to determine if the user is in a first activity state not corresponding to the intended activity by processing the output from the at least one sensor.

A head for a walk-around costume is provided that is adapted for enhanced visibility. The costume head includes an outer shell defining an interior space for receiving a head of a human performer. The outer shell includes an aperture allowing incoming light from an exterior space to enter the interior space, and an eye location for the human performer is spaced apart from the aperture when the head is received in the interior space. To provide an enlarged field of view, the costume head includes an optical viewfinder assembly disposed within the interior space of the outer shell between the aperture and the eye location. The optical viewfinder assembly is adapted for receiving the incoming light and transmitting the incoming light to the eye location to move a viewpoint of the human performer to the aperture to provide a larger field of view of the exterior space.

A real-time virtual reality welding system including a programmable processor-based subsystem, a spatial tracker operatively connected to the programmable processor-based subsystem, at least one mock welding tool capable of being spatially tracked by the spatial tracker, and at least one display device operatively connected to the programmable processor-based subsystem. The system is capable of simulating, in virtual reality space, a weld puddle having real-time molten metal fluidity and heat dissipation characteristics. The system is further capable of importing data into the virtual reality welding system and analyzing the data to characterize a student welder's progress and to provide training.
