A saddle-type vehicle includes a helmet and an occupant authentication device configured to perform authentication of an occupant by a small camera (an imaging element) provided in the helmet. The occupant authentication device releases lock on the vehicle if the occupant is authenticated.

A helmet with an outer shell, an inner liner, a plurality of vents, and an occipital cliff is disclosed. The outer shell includes an outer surface made up of a first and second surface, the first and second surfaces joined by a drop-off running across the outer surface from a left side of the helmet to a right side of the helmet. A majority of the drop-off is closer to a coronal plane bisecting the helmet than it is to the rear of the helmet. The drop-off is contained within a posterior section of the helmet defined by the coronal plane. The first surface defines a top of the drop-off and the second surface defines a bottom of the drop-off, such that the drop-off has a height. The occipital cliff is located at the rear end of the helmet and is approximately perpendicular to the second surface proximate the drop-off.

A tilt resistor is interposed between shoulder pads or other torso support structures and a helmet. The helmet is coupled to one side of the tilt resistor and the torso support is coupled to another side of the tilt resistor. The tilt resistor acts as a pivot joint allowing the helmet to tilt about a horizontal lateral axis relative to the torso support. An acceleration sensor associated with the tilt resistor locks the tilt resistor so that the helmet stops tilting when tilting acceleration sensed by the accelerometer is greater than a desired maximum amount. The tilt resistor is coupled to the torso support, preferably through a collar, which allows rotation of the tilt resistor about a vertical axis. Stops are provided to limit both rotation about a vertical axis and tilting motion within limited ranges that are preferably adjustable.

A technique relates to a head apparatus for a user. A structure has an opening. A light source includes one or more graphene elements.

A personal protection and ventilation system is provided. The system includes a gown having front and rear panels, a hood, and visor; a fan; an air tube; and a helmet. The fan is positioned between the wearer and a body-facing surface of the rear panel. The front panel and at least a portion of the hood are formed from a first material including a first spunbond layer, a spunbond-meltblown-spunbond laminate, and a liquid impervious elastic film disposed therebetween. The first material has an air volumetric flow rate of less than about 1 standard cubic feet per minute (scfm). The rear panel is formed from a second material including a nonwoven laminate having an air volumetric flow rate of about 20 scfm to about 80 scfm. Therefore, the fan is able to intake a sufficient amount of air from the environment through the rear panel to provide cooling/ventilation to the hood.

Flashlight having modular mount system with integral mount element on the flashlight body and/or having programmable rear-facing signal lights.

The proposed display system providing in the motorcyclist's field of view all visual information needed for driving and maneuvering in form of the image projected into optical infinity in direction of the motorcycle travel so to watch the traffic situation the motorcyclist does not need to turn his head to the rear view mirrors with temporary interruption of eye contact with the road because of necessity of the visual apparatus readjusting, is realized by use of located in the motorcyclist's helmet the autonomous optoelectronic system including the display module with the programmable control unit forming in the motorcyclist's field of view the collimated image of sensors readings in the form of numbers and scales and also a TV image of rear hemisphere and the real-time picture according to GPS data: the connection between the equipment placed in the helmet and the motorcycle movement sensors. TV camera and GPS receiver is carried out using the Wi-Fi technology.

Disclosed herein is a head protector. The head protector includes: a pair of fastening straps (100) configured to be attached to the outer surface of one side of headgear (10); and a protective panel (200) configured such that it is seated to cover the outer surface of the one side of the headgear (10) and such that a central part thereof is spaced apart from the outer surface of the headgear (10), and provided with a pair of fastening holes (202) through which the pair of fastening straps (100) pass. The pair of fastening straps (100) pass through the pair of fastening holes (202) and are fastened to each other so that the protective panel (200) is fastened to the outer surface of the one side of the headgear (10).
