A method of providing synchronization and integrity checking in a high integrity processing system having at least two redundant processing lanes, with each lane having an application processor, with the application processors running the same application software in a non-lockstep configuration, and outputting transactions requiring access to an addressable space. It is possible to avoid influence of adaptation of the eye by making chromaticity of a target white point ) close to chromaticity of white of the image output apparatus ). The mobile plate is adapted to move along the transverse valve actuation axis: from a fully open position, wherein the upstream and downstream orifices are in flow communication; to a fully closed position, wherein the downstream orifices are blocked by the mobile plate. Method also includes determining first set of characteristics based on representation of first set of audio files. The soldering control unit is provided on each of the main surface of the first bus bar to which the first electrode plate is soldered and the main surface of the second bus bar to which the second electrode plate is soldered, and controls the solder joint thickness. According to various embodiments, a communication interface may receive image data that is stored in a semi-volatile NAND flash memory device divided into three regions.
