Abstract: Various embodiments of the present technology generally relate to treatment for dry eyes. More specifically, some embodiments of the present technology relate to eyeglass frames for treatment of dry eye syndrome and corresponding three-dimensional printing systems and methods. In some embodiments an eyewear apparatus includes a frame with a seal configured to engage with the skin of the wearer around a majority of the perimeter of an interior portion of the front of the frame sufficient to keep the humidity around the eye high enough to provide relief from symptoms of dry eye syndrome.

Abstract: An integrated three-chamber absorption refrigeration and heat pump system with improved defrost capabilities having a solution pair including a material of .[.unusable.]. .Iadd.unusual .Iaddend.fluid stability at higher temperatures when manipulated in an apparatus and system to take advantage of its properties. Disclosed materials of a solution pair for operation as part of the system of this invention are ammonia as the refrigerant and sodium thiocyanate as the absorbent. A heat transfer sub-system is provided, for conveying a working fluid between the components, having multiple switchable valve means, including first, second, and third valve members selectively switchable to convey the working fluid from the cooling mode to the heating mode and vice versa, as well as to the defrost mode.
