An automatic gain control method and circuit within a receiver uses a digital state machine to implement the AGC function. Web-based servers or the like can provide a single point of access for remote users to manage access to distributed content on one hand, and to manage use of distributed fabrication resources on the other. A method of identifying Tpl2 specific inhibitors of endotoxin shock or antagonists to inflammation on and a method of treating or preventing TNF-mediated inflammatory diseases and Lps induced endotoxin shock in animals are also within the scope of this invention. A strain generation member 23 is arranged across from the upper horizontal frame 1b to the vertical frame 1c. The light resolution element includes a prismatic body operable to guide and re-orient a light beam passed thereto from the light guiding apparatus.
