The desulfurization of petroleum distillates can be carried out by cyclic low-temperature adsorption of oxidized sulfur compounds with activated carbon followed by regeneration of the activated carbon using an organic solvent. The module includes an internal housing having an outer dimension substantially equal to an outer dimension of an internal fiber splice housing of an undersea optical fiber cable joint. A flexible thin plate is attached to upper surfaces of the small plate-like members so as to allow longitudinal and lateral folding. The first receiver includes a latch configured to retain the first projection when the first projection is initially inserted or pushed into the first receiver. The hysteresis processor performs hysteresis processing on the digital torque signal to include the value of the digital torque signal in a predetermined range. Embodiments are described in which the method is used to improve received audio signals in DAB receivers and mobile telephones.
