Abstract: Provided is an optical element for a lithographic apparatus. The optical element includes a capping layer that includes oxygen vacancies therein. The oxygen vacancies prevent attack of the capping layer by preventing hydrogen and other species from penetrating the capping layer and underlying layers. The capping layer provides a low hydrogen recombination rate enabling hydrogen to clean the surface of the optical element.

Abstract: A method and apparatus for protecting the seed laser a laser produced plasma (LPP) extreme ultraviolet (EUV) light system are disclosed. An isolation stage positioned on an optical path diverts light reflected from further components in the LPP EUV light system from reaching the seed laser. The isolation stage comprises two AOMs that are separated by a delay line. The AOMs, when open, direct light onto the optical path and, when closed, direct light away from the optical path. The delay introduced by the delay line is determined so that the opening and the closing of the AOMs can be timed to direct a forward-moving pulse onto the optical path and to divert reflected light at other times. The isolation stage can be positioned between gain elements to prevent amplified reflected light from reaching the seed laser and other potentially harmful effects.

Abstract: A user programmable universal industrial wireless control system for remotely controlling industrial equipment. The industrial control system includes relay systems that are connected with a stopping and starting system of the industrial equipment. The industrial control system, according to the signals received from the transmitter, causes the relay systems to be either energized or de-energized as required to start and/or stop the industrial equipment. The relay systems are user programmable to be either momentary, maintained, or have timer functions.

Abstract: This invention is directed to an apparatus having a number of individual storage compartments for a plurality of game pieces. The pieces are used in a number of board games. Some pieces are unique to one game, and some pieces are common to two or more games. Selection of desired game pieces is obtained by placing a template, with discretely positioned holes cut therein, over the storage apparatus, blocking access to all compartments except those containing the desired pieces for the particular game. Those desired pieces can then be removed either manually or by turning the apparatus upside down allowing the pieces to fall out. The template is then left in place until the pieces are again ready for storage, thus facilitating the replacement of the pieces into their proper compartments in the storage apparatus.
