Abstract: A corrosion inhibiting coating for metal objects as well as a method for applying a coating is described. Said coating comprising at least one cerium oxide and at least one polymer. The polymer comprises at least one cathecholic component covalently bound thereto, and the at least one polymer displays a net positive charge at a pH of 7. The material inventive coating is environmental friendly and does not display serious health risks. Further an excellent corrosion inhibition is obtained for metals, even for carbon steel. The corrosion the properties of a coated surface is comparable with those of stainless steel.

Abstract: A method for prevention of corrosion of a metal object comprises applying a coating to the metal object. Thee coating comprises at least one cerium oxide and at least one polymer. The at least one polymer comprises at least one catecholic component covalently bound thereto and displays a net positive charge at a pH of 7.

Abstract: An electronic article surveillance system and method are disclosed. Pulses are emitted in an electromagnetic field, and in monitoring intervals between the pulses, reply signals are received from alarm labels within the surveillance area of the system. An incoming signal is sampled in the system. The zero crossings of the sampled signals are identified, and the phase positions thereof are compared with corresponding phase positions of zero crossings of an incoming signal, received and sampled in a previous monitoring interval. If these phase positions agree sufficiently well, an alarm can be initiated.
