A modular storage system capable of mounting storage fixtures such as shelves, drawers, rods, desks, hampers, trash cans and the like in various configurations without the use of tools and fastener hardware. Optimized portions will include gates whose design parameters are to be changed, a first analyzed portion includes gates whose delays and edge slews are to be recomputed, and a second analyzed portion includes gates whose ATs and RATs are to be recomputed during optimization. Using multiple distance vectors from multiple wireless network devices, a 2-D or 3-D coordinate representation for position of each wireless network in 2-D or 3-D space can be calculated. The external data stored in a personal computer is inputted into the tape printing apparatus via a cable.
