A barrier system, device, and method protects medical professionals and patients from exposure to contaminants and bodily fluids is provided. The system includes a head unit shaped to be worn over the head of the wearer; a hood positioned over the head unit; one or more sensors configured to produce one or more sensor-output signals; and a controller connected to the one or more sensors and configured to produce one or more controller-output signals based on the one or more sensor-output signals. Further, a device inside a barrier system is controlled by (a) sensing one or more characteristics; (b) producing one or more sensor signals based on the sensed one or more characteristics; (c) converting and/or processing the one or more sensor signals to produce one or more controller-output signals; and (d) controlling the device based on the one or more controller-output signals.

The invention relates to an interface for connecting an optical device and a mobile support which cooperates securely with an imprinted element, the interface having a base arranged to be inserted into the imprinted element, the base being a hollow body. The base accommodates mechanical play compensating structures which are movably mounted within the hollow body so as to project and are arranged in order to bear against a wall of the imprinted element.

A head unit system (24) for a head (22) of a user (20), including a headpiece (26) for being worn over the head (22) with a support structure (28) shaped to be worn over the head (22). A shield mount (30) attached to the support structure (28) is arranged for supporting a face shield (32) adjacent to the head (22). A headpiece connector (34) is attached to the support structure (28) and has a headpiece contact (36) configured for electrical connection. First and second peripheral devices are provided for being secured to the headpiece (26) for concurrent movement, and each respectively has a device connector (40) with a device contact (42) configured for electrical connection. The device connectors (40) and the headpiece connector (34) cooperate to releasably attach one of the respective peripheral devices to the headpiece (26) in a secured configuration (44) with the respective headpiece contact (36) and the device contact (42) abutting in the secured configuration (44) so as to facilitate electrical connection between the headpiece (26) and the secured peripheral device.

A helmet including fit system straps with illuminable strips on them or woven into them and one or more light sources positioned adjacent the tops of the fit system straps on the helmet body to emit light toward the illuminable strips. The light sources may be connected directly to the illuminable strips to emit light into an end of the illuminable strips. The light sources may emit light from or near a lower surface of the helmet body toward the illuminable strips.

A viewing device for off-road activities, comprising a visor (5), at least a package (2) of tear-off lenses (3) mountable on a lens (6) of the visor (5), and retaining means of the visor (5), wherein the tear-off lenses (3) have superimposable through holes (9). The device further comprises a retaining thread (4) reversibly associated with the visor (5) and with the retaining means of the visor (5), wherein the tear-off lenses (3) after being torn off are able to be retained by the retaining thread (4) sliding along it by means of the through holes (9).

There is provided a visor assembly, preferably for the motorcycle helmet, comprising a shield-visor having a surface, an overlay-visor adapted to be releasably attached to the shield-visor, the overlay-visor comprising a viewing area, a spacer with a tackified distal surface gasket, releasably adhering the overlay-visor to the surface of the shield-visor.

A virtual reality multi-sensory system includes an overhang rotatable multi-sensory device and a head-mounted multi-sensory device. The overhang rotatable multi-sensory device includes a fixed base, a control unit, a rotatable base, a driving device and a multi-sensory module having at least one selecting from the group consisting of a wind module, a hot air module, a heat module, and a liquid mist module. The head-mounted multi-sensory device includes a helmet, a display screen, earphones, a positioning module and an air flow guiding module. The present invention truly simulates image, sound effect, air flow, humidity, temperature, and smell of a specific environment, to stimulate the senses of sight, hearing, smell, and touch etc. of the user, thereby allowing the user to have an immersive experience in the simulated environment and avoiding increasing physical burden on the user's body.
