An edulcorating composition containing 5 to 20% by weight of inulin or fruitoligosaccharides, from 2 to 15% by weight of jellying fibres, 0. The apparatus includes a message candidate extraction module which compares message rules with the reconstructed messages, and extracts messages in the message rules which are identical to the reconstructed messages, from the messages defined in the message rules, as message candidates. The patterned metal layer is disposed over the circuit devices. The ridge follows an ascending slope to an apex. This display surface protective film excels in antistatic properties, scratch resistance, slip characteristics, transparency, etc. The system and method exercises the controlled devices during a testing regime, and monitors electrical current drawn by the spa system during the testing regime.
