Abstract: An apparatus (1) adapted to share information contents through wireless connection includes a processor adapted to read at least one information content (65) from memory (3, 4, 7) and at least a radio communication module (2) adapted to automatically transmit at least one information content (65) to an electronic device (80) as a consequence of the fact that the electronic device (80) is located in the radio communication range of the radio communication module (2), without the need for explicitly entering into the apparatus (1) or into the electronic device (80) any specific command for transferring the information content (65).

Abstract: Microwave signal equalizer comprising a signal transmission line, a first open stub and a second open stub which are applied in parallel to the said transmission line by a respective connection circuit, said first open stub and second open stub being controlled by at least one second dc control voltage which is applied to the respective connection circuit, said second control voltage being variable and said connection circuit being able to produce a variable resistance upon variation of said second control voltage.

Abstract: An electronic addressing system to read matrices of optical-electronic elements, wherein the optical-electronic elements are of any type, for example photoresistors, photodiodes, light emitters, and the like. The matrices are bi-dimensional and comprise optical-electronic elements arranged according to a row-column structure, without any auxiliary switching an/or commutating means connected therewith. One end of each one of the elements is connected with a corresponding row near each row-column crossover, and the other end is connected with the column related to the crossover. The switching of each one of the optical-electronic elements which is addressed for reading is obtained by an adaptive analog compensation technique, whereby only a single element is read out while all other elements are electrically isolated.
