    摘要: The invention concerns a method for transmitting in an area (100) information items in the form of sound waves representing a signal X(t), through a loudspeaker enclosure (2), said method comprising a step of setting up a public address system which consists in applying to the input of the loudspeaker enclosure (2) an electric signal P(t)=W(t) .Sc(f), wherein f represents the frequency, t0 is a constant Sc(f)=1/(S1(f)) , alpha being a non-null positive number and S1(f) being a real function obtained by peak clipping of the modulo I S(f) I of the frequency response S(f) of S(t).

    摘要: The invention concerns methods for authenticating images taken by camera systems (3) for photographing offending vehicles (1), for example upon excess of authorized speed limit, wherein means are provided for supplying data concerning the offence, such as the vehicle speed, the date, the time and the location of the offence and applying various processes which enable the images to be used, to detect any manipulations performed on said images.
