Abstract: A method and apparatus for making a lens includes a front mold (90) which has a reflective, UV absorptive surface, a back mold (50) which is UV light transmissive and a gasket (60) which holds the molds and defines a lens forming cavity (78) therebetween which receives polymerizable resin material (130). The resin (130) in the lens forming cavity (78) is exposed to a source of UV light (20) to cure the resin (130) and form the lens. Photochromatic coatings can be applied to the lens and cured.

Abstract: An improved and accurate enthalpy tunnel is presented, designed to condition and control airflow patterns within the main tunnel and air sampling subsystem so as to present a homogenous volume immediately upon introduction into the enthalpy tunnel. The air volume velocity is slowed and the air volume is completely mixed in a settling chamber which also serves to maintain the static discharge pressure on the unit under test. The rectangular design in use in the industry is replaced with circular geometry, using a cylindrical tunnel shape as opposed to a rectangular shape. The circular geometry creates a flat, uniform velocity profile. This tunnel improves the design of current art enthalpy tunnels by using a single nozzle instead of a bank of nozzles, presenting to the sampling mechanism a smooth, stable and uniform flow profile. The sampling method used in the prior art is replaced with a sampling tunnel that also conditions its air flow profile, leading to consistent sampling.

Abstract: A device for holding and dispensing a disinfectant liquid such as isopropyl alcohol from one section of the device, and holding and dispensing sterile swabs from another section of the device. A single unit combines a storage and delivery unit for the liquid disinfectant and a storage and delivery unit for sterile swabs. The liquid disinfectant is stored in a refillable container with a pump for delivering the disinfectant. The disinfectant storage unit is refilled with a hollow needle, puncturing a self-sealing membrane and injecting the disinfectant fluid into the storage unit. Complete sterility of the disinfectant fluid can thereby be maintained. A second holding and dispensing unit is combined with the liquid unit. A series of individually wrapped sterile swabs is stacked into a spring-loaded cylinder. Swabs are individually removed from one end of the unit, and replaced by the next one in the stack.
