A helmet, has a shell that includes a first portion and a second portion. The first portion has first, second and third layers. The second layer is positioned between the first layer and the third layer. The second layer is less dense than the first layer and the third layer. The second portion has a plurality of enemy dissipaters. Each of the energy dissipaters has a rod that extends in a spiraling manner from a fixed end to a free end. The rod tapers continuously along its length from the fixed end to the free end so that the fixed end exhibits a larger internal cross sectional area than the free end. The free end is capable of vibrating when the helmet is impacted by an object in order to dissipate impact energy.

One variation of a system for serving augmented visual content to a user includes: a visor including a substrate of a transparent material and a reflective coating applied across the substrate, configured to selectively reflect visible light within a first reflection channel, and configured to transmit wavelengths of visible light outside of the first reflection channel, wherein the first reflection channel spans a first band of wavelengths; a projection system configured to project visual content in a first output channel onto an interior surface of the visor, the first output channel including a first peak-power wavelength of visible light within the first reflection channel and excluding wavelengths of visible light outside the first reflection channel; and a support structure configured to locate the visor on the user's head with the visor in a field of view of the user and configured to locate the projection system relative to the visor.

The invention relates to an improved helmet. The helmet has a visor that can quickly and easily attach and detach from a forward-facing position on the front portion of the helmet to a backward-facing position on the rear portion of the helmet.

Compressible conical springs with unsecured tabs are positioned between an outer helmet and an inner rigid liner to absorb and distribute impact forces to minimize concussion risks and other head injuries.

An impact resistance spreading helmet is disclosed. The helmet includes a frontal section configured to interface with the forehead of an individual and extend upward over the cranium; a medial section for extending over a portion of the cranium rearward of the frontal section; an occipital section for extending rearward from the medial section and configured to cover a portion of the neck of the individual; a first compressible structure disposed between the frontal section and the medial section; and a second compressible structure disposed between the medial section and the occipital section. The interface between the frontal section and the first compressible structure is disposed at an angle vertical to a force direction perpendicular to the frontal section above the forehead of the individual.

A flex cell for absorbing energy from an applied force includes a panel attached to a flex cage. The flex cage is made from a resilient material that allows deformation of the flex cage when a force is applied to the flex cell. The flex cell is attachable to a support surface. In some instances, the flex cell is detached from the support surface when sufficient force is applied to the flex cell.

A shield adapted for use with a baseball cap or caps used in other sports is disclosed to protect a pitcher or fielder from a batted or thrown baseball or softball. A panel is shaped to conform with a front side of a ball cap and is secured with straps or other means on the outer side of the ball cap or, alternatively, on the inner side of the ball cap. The shield is formed of a sheet or panel of impact absorbing plastic that protects the user from trauma in the event of a collision with a traveling ball or other object.
