DEVICE FOR READING INFORMATION FROM A DIFFERENTIAL DATA BUS WITHOUT GALVANIC CONNECTION THERETO

The invention relates to a device for reading information from a differential digital bus without galvanic wire connection thereto. According to the invention, the device consists of two capacitive transducers (5a and 5b) consisting of a box (5) with two covers (9a and 9b) and two guiding channels (11a and 11b) wherein there are fixed two lines (4a and 4b) wherefrom some signals are intended to be taken over, the said box (5) being closed after fastening, the two capacitive transducers (5a and 5b) providing some signals to a signal processing circuit (2) which transmits them by a coupling means (6) to a computer, the signal processing circuit (2) being applied to a circuit (14) which contains two amplifiers which take over the signals provided by the transducers (5a and 5b) and transmit them to a circuit which discriminates between the two signals, the so obtained signal being then filtered and applied to an analogue-digital convertor (15), after which another circuit (16) reconstitutes the signals of the two lines wherefrom the processed signals were read.
