  • Patent number: 10845654
    Abstract: A method for manufacturing an optical device and an optical device is provided. The manufacturing method is capable of minimizing or eliminating dotting unevenness that may occur when an optical device is manufactured by a dotting process. In particular, even when a large cell gap is present or a polymer substrate is applied as a substrate so that high-temperature heat treatment is impossible, such method of the present application can provide an alignment film having improved orientation by improving the dotting unevenness.

  • Patent number: 10845011
    Abstract: A system of lighting for an artificial tree or other decoration that allows easy replacement of small sub-strings of luminaries. Each sub-string contains N luminaries, where N is an integer around 10, where the N luminaries are wired in series. Extender cables can be supplied that contain parallel splits so that the different sub-strings are operated in parallel. The extender cable can attach to a master power source that supplies the constant voltage needed to power each sub-string. The exact voltage is determined by the number N and by the voltage requirement for each of the luminaries. Each sub-string has a plug that mates with a receptacle on either an extender cable, or on the master power device. Single point failures only cause one sub-string to go dark. The physical arrangement with plugs and receptacles allows easy replacement of an individual sub-string that is dark because of a failed luminary.
