A woven fabric formed of a first set of yarns extending in a first direction, woven together with a second set of yarns extending in a second direction. The first set includes first conductors, while the second set includes second conductors. The first and second conductors cross over one another at crossing points. At each crossing point, a non-conductive element is disposed directly between the first and second conductors so as to provide a physical barrier between the first and second conductors. At some crossing points, a physical electrical connection is provided between crossing conductors in order to provide a permanent connection between the conductors. Non-conductive tie yarns are provided to fix the conductors in position. The structure provides a robust yarn with minimized risk of short circuiting between crossing conductors which are intended to be kept separate.

A flip-to-wear eye shield system is provided. By integrating a hinge into elements of the frame and/or the lens, the eye shield can be manufactured and assembled more quickly and with less costs. In an embodiment, a lens may click (or snap) onto molded posts of a frame in a substantially flat position. An integrated living hinge in the frame may bend to allow the lens to flip downwards toward the frame to a second position for use. The posts may also click (or snap) into place in an underside of the frames. In another embodiment, a lens may click (or snap) onto molded posts of a flame in a substantially flat position. An integrated living hinge, formed by notches in the lens, may allow the lens to bend to flip downwards to the frame to a second position for use. A dispenser allows storing the eye shields in the flat position and dispensing in the second position for use.

Earphone apparatus includes dry electrophysiological electrodes and, optionally, other physiological and/or environmental sensors to measure signals such as ECG from the head of a subject. Methods of use of such apparatus to provide fitness, health, or other measured or derived, estimated, or predicted metrics are also disclosed.

A portable brim can be securely attached to and operate with various helmets such as bicycle, skateboarding, snow sport, mountain/rock climbing, equestrian, and paddlesport helmets as well as hard hats used in construction, utility maintenance, material moving, dock loading, and airport baggage handling, to give the wearer shade and protection from the sun. The brim apparatus includes a center section having a size for fitting about a circumference of the sports helmet and a visor outwardly or radially extending from the center section. In one brim apparatus the center section features a stop surface that opposes an upper surface of the visor when the apparatus is affixed to the headgear such that the visor is prohibited from flipping upwards or sliding down or coming off during use.

The invention relates to a protective helmet, and in particular, to a protective motorcycle helmet, comprising an antenna (1) for radio transmission, an outer shell (2) for distributing impact forces, an inner layer (3), which is accommodated by the outer shell (2), for damping impact forces, and a socket (4), which is firmly connected to the outer shell (2), for contacting a digital device (5) for wireless communication, wherein the socket (4), when contacting the digital device (5), electrically connects the latter to the antenna (1) for wireless communication. The protective helmet is characterized in that at least a partial layer of the outer shell (2) is disposed between the antenna (1) and the inner layer (3).

A head mounted device for a helmet includes a connection module, a flexible bracket, a power supply seat and a function module. While the flexible bracket is moved relative to the connection module, a position of the power supply seat relative to the helmet is adjusted. While the function module is moved relative to the power supply seat, an orientation of the function unit is adjusted.

An energy absorption system is provided with a plurality of energy absorbing panels that may be releasably connected to a helmet. The energy absorbing panels are provided with a plurality of air flow channels defining a plurality of energy absorption chambers. Each of the air flow channels is designed to direct air flow from an anterior of the helmet to a posterior of the helmet when the energy absorbing panels are connected to an outer shell of the helmet.

An impact awareness device (IAD) may include an impact switch configured to transition from an open-circuit state to a close-circuit state when a force is exerted on the IAD in a first direction and exceeds a force threshold. The IAD may further include a headliner configured to couple with a protective headgear. The headliner may include a flexible band comprising one or more substrates configured to conform to a headband of the protective headgear, and an electronic circuit coupled to the flexible band and electrically coupled to the switch and wherein when the force threshold is exceeded the electronic circuit transmits an indication signal to provide an indication of the likelihood of a head and a vertebral column injuries when the indicator signal is received.
