A method of controlling the shape of a plurality of relief dots created in a photosensitive printing blank during a digital platemaking process is provided. The distal ends of the rods are mounted to the footboard assemblies, respectively, and the proximal ends of the rods are mountable to a common support means located above the footboard assemblies. Each intensity-energy function can include a set of modes in which the optical cavity provides output light. The arm’s front end is bent toward the first stopper block to form a first transversal plate. A transmitter modulates a sequence of bits in a wireless communications network by selecting one coding sequence from a set of orthogonal or quasi-orthogonal coding sequences based on a current subsequence of bits of the input sequence, generating a reference waveform and a data waveform of a waveform pair for each sequence. During construction, the shells, which may be hemispherical, are mated together and then the lock mechanisms are secured to the shells to form a substantially smooth-surfaced sphere.
