A helmet includes a non-contact sensor for a living body, a cap body, and a headband attached to an inner side of the cap body. The headband is provided with a first projection and a second projection on a surface facing a front head portion (FD) of the cap body. The non-contact sensor for the living body includes a first housing having a first surface and a second surface opposing the first surface, a first claw portion provided on the first surface, and a second claw portion provided on the second surface. The first claw portion is brought into contact with and fixed to the first projection, and the second claw portion is brought into contact with and fixed to the second projection.

A wearable impact protection and force channeling device operable to transfer force received via impact from a head of the user to a body of the user, thereby utilizing an entire mass of the user to lessen rapid momentum change of the head.

An auto-darkening welding helmet comprises a helmet casing; an auto-darkening filter installed in the helmet casing; and a lighting device installed in the helmet casing, wherein the auto-darkening filter includes a liquid crystal panel which is switchable between a non-opaque state and an opaque state, wherein the lighting device comprises a cable connectable to the auto-darkening filter such that when the liquid crystal panel is in the non-opaque state the lighting device automatically emits light towards a front of the liquid crystal panel and when the liquid crystal panel is in the opaque state the lighting device does not automatically emit light.

A head-mounted display includes a wearing part, a display body, a strap, a follower, and a buckle assembly. The display body is disposed on the wearing part. The strap includes a first end, a second end, and a handle portion. The wearing part is located at a front side of a wearing space surrounded by the strap. The first end and the second end are overlapped at the front side. The handle portion is located at the first end or the second end. The follower is disposed on the wearing part and coupled to the first end and the second end. The buckle assembly is disposed between the wearing part and the first end, and is adapted to lock a relative position between the wearing part and the first end in a buckled state and remove the interference between the wearing part and the first end in a released state.

A device for connecting a mouthguard with a helmet includes a clip assembly with a base adapted for connection with the helmet and an arm releasably connected at a first end with the base. The arm is formed of resilient material and operable between an open position for receiving the mouthguard and a closed position for retaining the mouthguard against the helmet. The arm preferably has an elongated concave configuration and includes a second end having a first portion which abuts against the helmet and a second portion for engagement by a finger of a user to displace the arm between the open and closed position.

The invention concerns an augmented vision system (1) comprising: a displaying device (3) comprising: a fixing element (31) for coupling the displaying device (3) to a head-mountable component (90) configured to be positioned in front of a 5 face (102) of a user (100), and a display body (32) being coupled to said fixing element (31) by means of a pivoting link (321, 322, 323) providing a rotation of the display body with respect to the fixing element around a rotational axis (38); the display body (32) comprising 10 a display (33) configured to display thermal data and/or images provided by a thermal sensing device (2); and a first surface portion (325) configured to enter in contact with a forehead of a user, when said head-mountable component (90) is positioned in front of the face of the user, so as to rotate the display 15 body (32) to a predefined angular positioning (381) around the rotational axis (38).

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.
