Abstract

The invention is directed to a broadhead for bowhunting that provides significant advantages for ethical and efficient kills, that may be tailored for different target animals. It is an aspect of the invention to provide a broadhead design with a narrow profile in flight and penetration and a large cutting surface length to weight ratio while transiting the target animal. The broadhead maximizes efficient use of the majority of the forward momentum energy and the stored kinetic energy from the bow or crossbow to the arrow shaft to humanely impact and quickly and ethically kill the targeted animal. This is achieved without decreasing the accuracy and maximum penetration and lethal cutting of the broadhead upon impact and as it passes through the target animal. The broadhead minimizes deflection and provides lethal cutting surfaces that are exposed at all times.

Abstract

A dual-mode switchable liquid-crystal window can control both radiant energy flow and privacy. The modes are selected by using different voltage frequencies. A dichroic dye is doped to enable modulation of transmission of the window. In the absence of an applied voltage, the window is transparent without haze. When a high-frequency (e.g., 1 kHz) voltage is applied, the liquid crystal and doped dye molecules inside the window reorient uniformly under dielectric interactions. The material becomes optically absorbing. The transmittance decreases, but the haze does not change. In this mode, the window can control radiant energy flow through the window. When a low-frequency (50 Hz) voltage is applied, the liquid crystal and doped dye molecules are switched into a micron-sized polydomain structure under flexoelectric interactions. The material becomes optically scattering and absorbing. The scenery behind the window is blocked. In this mode, privacy can be controlled. This dual-mode switchable window is suitable for architectural and automobile windows.

Radial widths of the central annular segments decrease with increasing distance away from the center of the central disk.

Abstract

A dual-mode switchable liquid-crystal window can control both radiant energy flow and privacy. The modes are selected by using different voltage frequencies. A dichroic dye is doped to enable modulation of transmission of the window. In the absence of an applied voltage, the window is transparent without haze. When a high-frequency (e.g., 1 kHz) voltage is applied, the liquid crystal and doped dye molecules inside the window reorient uniformly under dielectric interactions. The material becomes optically absorbing. The transmittance decreases, but the haze does not change. In this mode, the window can control radiant energy flow through the window. When a low-frequency (50 Hz) voltage is applied, the liquid crystal and doped dye molecules are switched into a micron-sized polydomain structure under flexoelectric interactions. The material becomes optically scattering and absorbing. The scenery behind the window is blocked. In this mode, privacy can be controlled. This dual-mode switchable window is suitable for architectural and automobile windows.

Abstract

A method for aligning molecular orientations of liquid crystals and/or polymeric materials into spatially variant patterns uses metamasks. When non-polarized or circularly polarized light is transmitted through or reflected by the metamasks, spatially varied polarization direction and intensity patterns of light can be generated. By projecting the optical patterns of the metamasks onto substrates coated with photoalignment materials, spatially variant molecular orientations encoded in the polarization and intensity patterns are induced in the photoalignment materials, and transfer into the liquid crystals. Possible designs for the metamask use nanostructures of metallic materials (e.g., rectangular nanocuboids of metallic materials arrayed on a transparent substrate).

Abstract

A bistable cholesteric liquid crystal switchable window has two stable states in the absence of an applied voltage. A first stable state is a planar state which is transparent or reflective for visible light. A second stable state is a focal conic state which is opaque for visible light. The window can be switched from the first stable state to the second stable state via a first voltage pulse and from the second stable state to the first stable state via a second voltage pulse. The first voltage pulse and the second voltage pulse may have the same frequency.

Abstract

Star block copolymers having 3 to 8 arms are formed as a 3D foam scaffold having tailor-made pore sizes that mimic an actual cell size of a specific animal and/or human tissue and/or organs. The pore sizes are made within the elastomeric foams via a salt leaching process wherein a salt of a specific particle size is blended within the star block copolymers and crosslinked as by polyisocyanate compounds. Water or other suitable solvent are utilized to dissolve and leach out the salt leaving an open pore system. Animal and/or human cells are then injected into the 3D elastomeric foam scaffold that contains pendant liquid crystals on the star block copolymer whereby with the aid of nutrients, cells are formed within the pore system that are viable for at least three months. The size of the pore is predetermined to produce a desired cultured cell having a desired size. The tissue and/or cells within the elastomeric scaffold can be applied to animal and/or human tissue and/or organs whereupon they grow and reconstruct the damaged, injured, diseased, etc., area and result in a healthy, repaired, and viable tissue or organ. The elastomeric liquid crystal containing foam scaffold will degrade naturally and/or also be consumed by the growing cells so that it no longer exists. In other words, a specific type of animal or human cell can be culturally produced having a predetermined average cell diameter that is substantially or essentially the same diameter of a natural cell.

When non-polarized or circularly polarized light is transmitted through or reflected by the metamasks, spatially varied polarization direction and intensity patterns of light can be generated. By projecting the optical patterns of the metamasks onto substrates coated with photoalignment materials, spatially variant molecular orientations encoded in the polarization and intensity patterns are induced in the photoalignment materials, and transfer into the liquid crystals. Possible designs for the metamask use nanostructures of metallic materials (e.g., rectangular nanocuboids of metallic materials arrayed on a transparent substrate).
