    • A method for checking the authenticity of a security article (158) wherein the security article contains magnetic particles having a magnetic saturation field Hs being greater than 100 A/m. The method comprises the following steps: (a) generating an alternating field of one or more fundamental frequencies; (b) subjecting an article (158) to be detected to said field; (c) detecting a detection signal emanating from said article to be detected; (d) examining the detection signal for the presence of any particular higher harmonics of said fundamental frequencies or of any linear combination of said fundamental frequencies and of said harmonics, said particular harmonics or said linear combination being indicative of the presence of said magnetic particles. The method is applied at point of transaction locations, where the article to be detected is brought into close proximity with a sensor. 00000

    • The invention relates to an infrared remote control signal processing circuit for processing a remote control signal. The processing circuit comprises within an integrated circuit a first and a second reception channel. The first reception channel is provided with a bandpass filter with a bandpass frequency that corresponds to a predetermined carrier frequency of the remote control signal. The second reception channel has no frequency filter or at least a filter with a wider bandpass range than the first reception channel. The two reception channels have respective allocated signal outputs for connection to an evaluation circuit.

    • An apparatus for detecting the presence of magnetic elongated particles in a substrate the base material of which has magnetic properties substantially differing from the corresponding magnetic properties of the elongated particles. The elongated particles have such a long and thin form that their demagnetisation factor N is smaller than 1/250, they have a diameter smaller than 30 micrometer and a magnetic saturation field greater than 100 A/m. The apparatus comprising: (a) means for emitting an electromagnetic source signal of one or more particular base frequencies to said substrate so that any present magnetic elongated particles go into a non-linear part of their B-H curve for at least part of a cycle of the source signal; (b) means for detecting an electromagnetic detection signal emanating from said substrate; (c) means for testing the detection signal for the presence of particular higher harmonics of said base frequencies or of any linear combination of said base frequencies or of said harmonics, said particular highher harmonics being indicative of the presence of said magnetic elongated particles. 00000
