A multifunctional lens assembly includes a functional transparent plate and a layered adhesive body. The functional transparent plate includes spaced apart through holes disposed in an outer peripheral region thereof. Each through hole extends through two opposite surfaces of the outer peripheral region. The layered adhesive body is attached to the functional transparent plate for adhering the functional transparent plate to a face shield of a mobile helmet. The layered adhesive body has a first layer 61 disposed on one of the two opposite surfaces of the outer peripheral region facing toward the face shield, and connection studs respectively extending through the through holes and integrally connecting the first layer.

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 sun visor for attaching to a wire cage-type sports face mask yet readily detachable if impacted, having a curved transparent sheet that extends in a U-shape to opposing sides, a pair of attachment connectors each on an inner surface proximate a distal extent of a respective side for engaging a respective side of the cage-type wire frame face mask.

Provided are a smart window, a sliding smart window, a smart window for a vehicle, a sun visor for a vehicle, a smart window device, and a head-mounted smart window device which have maximized user convenience.

An optical filter 100 for a visor is described. The optical filter 100 comprises a first layer 101 comprising a first notch filter 102 arranged to attenuate electromagnetic radiation having a first wavelength .sub.1 incident normally thereupon. The optical filter 100 comprises a second layer 103 comprising a second notch filter 104 arranged to attenuate electromagnetic radiation having a second wavelength .sub.2 incident normally thereupon. The first wavelength .sub.1 and the second wavelength .sub.2 are different. The second layer 103 is stacked upon the first layer 101. In use, the first notch filter 102 attenuates the electromagnetic radiation having a predetermined wavelength incident thereupon at a first angle of incidence .sub.1 and the second notch filter attenuates the electromagnetic radiation having the predetermined wavelength incident thereupon at a second angle of incidence .sub.2, wherein the first angle of incidence .sub.1 and the second angle of incidence .sub.2 are different.

A dynamically tinted display visor (DTDV) is disclosed. In embodiments, the DTDV includes a visor surface having an untinted or substantially transparent setting and a tinted or substantially opaque setting. The visor surface is fixed to a helmet worn by an operator (e.g., a pilot or co-pilot), the helmet further including a head tracking system for monitoring the head pose (e.g., head position and orientation) of the operator. Helmet-mounted cameras include auto-gain sensors capable of assessing ambient light levels consistent with the head pose of the operator. The DTDV includes a tint processor for adjusting the tint setting of the visor surface based on an assessment of the head pose data and sensed ambient light levels, automatically detinting or darkening the visor as conditions demand or manually detinting/darkening at the operator's command.

There is provided a visor assembly (1), preferably for the motorcycle helment, comprising a shield-visor (2) having a surface, an overlay-visor (6) adapted to be releasably attached to the shield-visor, the overlay-visor comprising a viewing area, an integrally formed spacer (7) extending along at least a portion of a periphery of the viewing area, and a gasket (8) upon a distal surface of the spacer; and a mechanical fastening (11) releasably attaching the overlay-visor to the surface of the shield-visor.

An electronic motorcycle helmet. The electronic motorcycle helmet includes a helmet having an aperture therein that can receive a head therethrough. A visor is disposed on a front side of the helmet and a display is disposed on an interior surface of the visor. A microprocessor, including a logic that receives a command input directed to one of a plurality of subsystems, toggles the subsystem between an activated state and a deactivated state, and displays a status window on the display corresponding to the subsystem. The plurality of subsystems includes a plurality of cameras disposed about the helmet, wherein each of the cameras is operably connected to the display and can apply a low-light filter for low-light conditions. Other subsystems include a wireless transmitter to wirelessly communicate with an external device, a GPS system, and a battery disposed at a lower edge of the rear side.

A visor locking mechanism is applied to a helmet equipped with a visor. The visor is provided on an inner side of an outer shell of the helmet which has a facial opening in a front side thereof. The visor is attached to a pair of left and right holders which are pivotably attached to the outer shell. The visor is configured to close or open at least part of the facial opening. A lock member that has an operation portion and a catch portion is disposed near at least one of the pair of holders. The operation portion allows the catch portion to fit together with or disengage from a catch counterpart portion provided at the pair of holders, whereby the visor becomes anchored or released.

A helmet including a hard shell defining an exterior surface and an interior volume of space and including a bill. A visor including an engagement structure that is releasably attached to the bill wherein the visor does not pivot relative to the bill when engaged with the bill.
