Abstract: Negative Poisson's ratio (NPR) or auxetic structures, including three-dimensional auxetic structures, are disclosed and applied to various applications. One such structure comprises a pyramid-shaped unit cell having four base points A, B, C, and D defining the corners of a square lying in a horizontal plane. Four stuffers of equal length or different lengths extend from a respective one of the base points to a point E spaced apart from the plane.

In three-dimensional configurations, a plurality of unit cells are arranged as tiles in the same horizontal plane with the base points of each cell connected to the base points of adjoining cells, thereby forming a horizontal layer.

In X-type auxetic stents, each unit cell comprises eight points from A to H defining an outline of the unit cell.

Abstract: The present invention relates to a mobile phone device, more specifically, to a sunlight illuminated and sunlight readable mobile phone device. The display panel opens a transparent window to the ambient light, which allows the sunlight to illuminate the display in both indoor and outdoor applications. A light collecting panel is introduced to reflect or transform the external light with a suitable angle relative to the display panel. A mobile phone with sufficient high contrast ratio, superior readability and ultra wide color gamut has been achieved. The solar light can be utilized as the lighting source in both indoor and outdoor display modes, thus remarkably reduces the power consumption and substantially prolongs the operation time of the rechargeable battery.

Lightweight, composite ballistic armor according to the invention may comprise an array of ceramic pellets, each pellet having a front surface, a back surface and a longitudinal centerline, and wherein the front surface of each pellet is intentionally convex. The front surface of each pellet may be hemispherical, in which case the cross-section of the pellet taken perpendicular to the centerline may be oval-shaped. Alternatively, the front surface of each pellet may be elliptical, in which case the cross-section of the pellet taken perpendicular to the centerline may be circular. In the preferred embodiment, the back surface of each pellet is formed at the same angle relative to its centerline, with the pellets being arranged with the flat surfaces lying in a plane.

Abstract: This invention relates to a high brightness and high contrast ratio reflective cholesteric displays employing circular polarizers. The front circular polarizer has a predetermined polarity that is opposite both to the Bragg reflection of the display and to the back reflective circular polarizer. An absorptive weak polarizer with high transmittance is adopted in the display system. In the black-and-white display mode, the white state is achieved in the cholesteric focal conic texture area; and the black state is obtained in the cholesteric planar texture area. In the full color mode, the full color state is created by the micro-color filter in the cholesteric focal conic texture area; and the black state is realized in the cholesteric planar texture area.

Abstract: Improved composite armor designs use optimally shaped ceramic pellets and a web system for patterning the pellets, improving manufacturability, and providing additional structural reinforcement. The result is lightweight, composite hybrid structures for ballistic protection particularly suited to tactical ground vehicles. The preferred embodiment is a combination of three major components: 1) an optimally designed web system that allows armor tiles to be attached to it and that can be easily integrated with existing vehicle structures; 2) an advanced composite armor unit using a patent-pending BTR (Bio-mimetic Tendon-Reinforced) material as the supporting structure; and 3) optimally placed “waiting materials” which can provide enhanced ballistic impact resistance, energy absorption capability and structural integrity. These “waiting materials” are structural members that are not active at the beginning of the ballistic impact, but become active when needed or the active members have failed.
