A forward error correcton coding method comprises a generalized concatenated code comprising a plurality of outer component codes and a plurality of inner component codes. Light emitting diodes having a shaped substrate are bonded to a submount by applying forces to the substrate an a manner such that shear forces within the substrate do not exceed a failure threshold of the substrate. The piston is housed with a sliding aptitude in a cylinder body in which it delimits two opposite chambers. The cam has a shape that is set so that a moment generated at the cam based on the elastic force applied by the contact element is generated so that a moment required to rotate the openingclosing body is in accordance with operation characteristics required for the openingclosing body. The method, adopted by a wireless communication device, includes: searching for a plurality of signal-source types; in response to the searching, determining whether a first type of signal source is available; setting a search configuration based on availability of the first type of signal source; and searching again for the plurality of signal-source types according to the search configuration.
