Abstract: A dual mode log periodic dipole antenna (20) provides for sum and difference radiation patterns depending on the method of excitation. The antenna incorporates a support structure (22a, 22b) which secures a plurality of radiators (24) having three elements with successively increasing length. The center and right dipole elements of each radiator (24) and the center and left elements of each radiator (24) are alternately coupled together by separate conductive elements (32) in a crisscross fashion. Input ports (28, 30) coupled to the smallest radiator (24a) are driven with conventional hybrid coupler with either in-phase or out-of-phase energy at either λ/2 or λ. Sum and difference radiation patterns are achieved by appropriate section of the excited phase. Thus, this antenna (20) may be employed in monopulse or direction finding applications.

Abstract: Method and device for picture data compression by vectorial quantification in accordance with a pre-encoding by blocks, and in comparison by a neural network of the pre-encoded blocks with reference words stored in the form of a dictionary for the purpose of transmitting selected indices to a receiver. According to the method, the neural network effects a learning with prescribed prototypes and then, using test vectors emanating from the picture, generates an adaptive dictionary which is transmitted to the receiver. This adaptation makes use of attractors, which may be induced metastable states of the neural network and which undergo an optimisation procedure. 
<??>The device may process pictures with a view to storage thereof. It is likewise possible to use two devices which operate alternately, one for generating the adaptive dictionary and the other for using it for the purpose of processing television-type pictures in real time.
