A method for assembling a radio frequency safe switch and detonator system in a non-RF free environment. A fault class is defined, as well as fault objects whose data haven’t yet been fetched from the database. The deflected elements are pushed outwardly by the needle to engage a recess in the port which locks the valve open until the needle is removed. And, the apparatus provides a reaction conduit for forming the gas clathrate by cooling, simultaneously with forcing the raw material liquid to flow through the reaction conduit. If the recognition algorithm determines a match, the potential videoconferencing participant may be authenticated to participate in the videoconference. The estimate of the blur is then used to remove the blur from an image.
