A method of detecting a tone signal from complex input samples r in a wireless communication system is disclosed. This protocol is faster, simpler and more streaming than prior methods, and handles binary and unicode data more efficiently. A cradle is pivotably coupled to the base and includes a pair of clamp members slidably coupled thereto. To accomplish the desired conversion, the parser uses information from a public schema, a private schema and a grammar. A second spacer is formed on sidewalls of the first spacer and vertical portions of the epitaxial semiconductor layer. According to the invention, accumulators are connected on the or each circuit in sufficient number for each accumulator to feed two pairs of brakes, each pair of brakes being mounted on a distinct landing gear unit, and an electrically-driven pump being arranged to maintain a predetermined pressure level in all of the accumulators of the circuit in question.
