Abstract: An eyewear lens coupling system and methods can be used during assembly of an eyewear. The system and methods may advantageously decrease optical distortion of the lens during assembly and use and/or may also advantageously increase retention of the lens to the eyewear frame to improve the overall quality of the eyewear.

Abstract: A firearm noise and recoil suppressor having a plurality of ported channels in fluid contact with the barrel to redirect some of the firing gasses for the purpose of distributing the firing propellant gasses out the discharge end of the firearm. The channels redirect part of the propellent gasses to exit the barrel at times other than when the main projectile discharge occurs thus reducing peak pressure, thus reducing noise and recoil. The channels are contained within the tubular device, being in fluid communication with the projectile passageway through ports that regulate the amount of gas flow. The channels direct gasses to exit the device through apertures at the projectile exit end of the device in at an angle of between parallel to the projectile to up to perpendicularly.

Abstract: An injection molding apparatus and method of use are provided whereby a net-molded optical article can be produced. Edge wave deviations are reduced by controlling the cooling profile of the resin. The apparatus can be configured to include at least one heat control element disposed adjacent to an edge of the mold cavity. After plasticized resin has been injected into the mold cavity, the edge of the mold cavity can be thermally regulated relative to the center of the cavity.
