DEVICE FOR CONTACTLESS TRANSMISSION OF ELECTRIC SIGNALS AND/OR ENERGY Russian patent published in 2002 - IPC

FIELD: contactless transmission of electric signals and/or energy between at least two mobile parts. SUBSTANCE: device designed for contactless transmission of electric signals and/or energy between at least two relatively moving parts each carrying several definite electromagnetic coupling members whose closest-area field ensures mentioned contactless transmission is characterized in that coupling members of at least one part form cascaded set of conductors with matched load and each coupling member is independent of other ones on this part and forms resonance-tuned system whose resonant frequency is higher than highest frequency of broadband signal being transmitted. Device of alternative design is characterized in that each of coupling members provided on at least one part has at least one resonator that has single member capable of resonating alone independently of remaining coupling members, its resonant frequency being approximately equal to frequency of transmitted signals; separate resonators are interconnected through other line with matched load. EFFECT: enhanced passband width and data transmission speed at reduced response to noise. 36 cl, 10 dwg
