Disclosed is a launch system of an affixed lower section of launch tubing and an upper section of launch tubing configured to telescope vertically from a stowed position within the hull of a submarine to a position just above the ocean surface for a launch operation of a projectile, with the upper section returning to a stowed position after the launch operation. Specifically, various techniques and systems are provided for utilizing a network device to efficiently add a new device to a local area network using an existing network device. The projection path includes a light generator, a pattern generating element such as a spatial light modulator, and projection optical elements including an output lens and a projector artifact suppression element located in the projection path between the SLM and the output lens. In some configurations, the casing may also define at least one indentations in a surface of the third layer, which may correspond in location with the indentation in the exterior surface. The increment quantity and the adjusted conversion relation are stored in the system.
