Abstract: A horn (12) for elementary antennas for telecommunications, in particular satellite telecommunications, characterized in that the horn (12) includes a first emitting-receiving portion (22) adapted to emit and receiving an electromagnetic wave at a first frequency and a second emitting-receiving portion (24) adapted to emit and receiving an electromagnetic wave at a second frequency, the second emitting-receiving portion (24) being distinct and separate from the first emitting-receiving portion (22) and the ratio between the second frequency and the first frequency being greater than 1.2, preferably greater than 1.5.

Abstract: The parabolic antenna positioner includes a base, a support cradle mounted so it can rotate relative to the base along a first axis of rotation, a mobile assembly including a parabolic antenna, supported by the support cradle, and mounted so it can rotate relative to the support cradle along a second axis of rotation, orthogonal to the first axis of rotation. The second axis of rotation is separated from the axis of rotation of the support cradle by a non-null distance measured in the plane of rotation of the cradle.

Abstract: An integrated antenna system for telecommunications comprises at least one substantially flat and circular antenna provided with a rotation axis coinciding with its axis, the antenna being fixedly joined to a support itself comprising a rotation axis. The rotation axis of the antenna is inclined by an angle ? relative to the rotation axis of the antenna support and the antenna beam forms an angle ? relative to the rotation axis of the antenna.

Abstract: A method for providing auditory correction for a hearing-impaired individual, including extracting pitch, voicing, energy and spectrum characteristics of an input speech signal. The method also includes modifying the extracted pitch characteristic by multiplying a pitch factor times the extracted pitch characteristic, modifying the extracted voicing characteristic by multiplying a voicing factor times the extracted voicing characteristic, modifying the extracted energy characteristic by applying a compression function to the extracted energy characteristic, and modifying the extracted spectrum characteristic by applying a homothetical compression function to the extracted spectrum characteristic. Further, a speech signal is reconstituted perceptible to the hearing-impaired individual based on the modified pitch, voicing, energy and spectrum characteristics.

Abstract: A surface wave dispersive filter spectrum analyzer is provided comprising two identical assemblies having "M-C-M" structure (premultiplication, convolution and post-multiplication, respectively by a first, second and third linearly frequency modulated ramps), one analyzing the signal to be analyzed, the other a reference signal, the output signal being obtained after mixing the output signals of the first and second assemblies in a mixer.
