International Classification:

F21V 9/14

US Classification:

362 19, 362558, 362560, 362607, 362613, 362627, 35948301, 35949301

Abstract:

The present invention provides a polarization-sensitive light homogenizer and a backlight and display using the same. The homogenizer improves the spatial luminance and color uniformity, increases the luminance in a direction normal to the homogenizer and provides increased luminance through polarized light recycling within the light homogenizer and backlight. In one embodiment, the homogenizer includes a polarization-sensitive anisotropic light-scattering (PDALS) region, a non-polarization-sensitive anisotropic light-scattering region, and a substantially non-scattering region. In a further embodiment, the non-scattering region is birefringent. The spatially non-uniform incident light flux from a backlight including one or more non-extended light emitting sources is scattered efficiently by the NPDASL region and is incident on the PDALS region which backscatters light orthogonal to the polarization state desired for efficient illumination of a liquid crystal display panel. The NPDASL and the PDALS form a multiple reflection cavity that will increase the spatial luminance while improving the light recycling of the appropriate polarization state. In a further embodiment the light homogenizer includes at least one of a light collimating region and a light re-directing region.

Abstract:

This invention is an upper body protection system for contact sport players with an external semi-rigid articulating system comprised of a Collar, a Sternal Plate, a Back Plate and three Epaulets on each side. The entire system is designed to protect the shoulders and upper body by dissipating the force of a blow and then redirecting the residual force to the strongest load bearing parts of the body behind and on the sides of the neck where the collar section rests. The system protects areas of the upper body (namely the plexus of nerves exiting at the sides of the neck [Erb's Point]; the collar bone [clavicle]; the A-C joint [Acromio-Clavicular Joint]; the shoulder blades [Scapulae]; the spine; the breast bone [sternum]; the ribs; and underlying vital organs that are prone to injury. The system offers maximum protection while also allowing almost complete freedom of movement.
