    摘要: A radio frequency rotary coupler with its power dividers/couplers separated among multiple circuit layers that are axially stacked and interconnected using coaxial feeds. This architecture allows for multiple layers of circuits with minimal outside diameter and while minimizing increase in axial length. The coupler includes a stator, rotor, and dynamic capacitive ring. The stator includes at least a first stator circuit layer with a primary stator power divider (SPD), a second stator circuit layer with at least one secondary SPD, and stator coaxial feeds coupling the primary SPD and the secondary SPD(s). The rotor includes a first rotor circuit layer with a primary rotor power divider (RPD), a second rotor circuit layer with at least one secondary RPD, and rotor coaxial feeds coupling the primary RPD and the secondary RPD(s). The dynamic capacitive ring couples the stator and the rotor via the secondary SPD(s) and RPD(s).

    摘要: A rotary joint includes a contactless electrical connection that has an annular shape, not extending into a central region surrounded and defined by the annular contactless electrical connection. The annular shape of the electrical connection portions allows other uses for the central region, such as for passing an optical signal through the rotary joint. Feeds are coupled to annular waveguide structures in both halves of the rotary joint, for input and output of signals. The feeds may provide connections to the annular waveguide structures at regularly-spaced circumferential intervals around the waveguide structures, such as at about every half-wavelength of the incoming (and outgoing) signals. The annular waveguide structures propagate signals in an axial direction, parallel to the axis of rotation of the rotary joint. The signals propagate contactlessly (non-electrically-conductively) across a gap in the axial direction between the two annular waveguides.

    摘要: A rotary coupler comprises a stator 1 having a first face 3a and a rotor 2 having a second face 4a, the first and second faces 3a, 4a being spaced apart from and facing each other. A first electrically conducting track 5 is provided on the first face 3a of the stator 1 which forms a transmission line and has spaced apart ends A, B and a second electrically conducting track 6 is provided on the second surface 4a of the rotor 2 also forming a transmission line and having spaced apart ends C, D. One end A of the first track 5, in use, is connected to signal generating means and the other end B of said first track IS connected to earth through a resistor substantially equal to the characteristic impedance of the transmission line. The first track 5 extends along a generally circular arc substantially around the first face 3a of the stator 1, said first track 5 having a length substantially equal to an integer number of wavelengths of the signal produced, in use, by the signal generating means. The second track (6) extends along a generally circular arc partially around said second face 4a of the rotor 2, said second track 6 having a length substantially equal to one quarter of the wavelength of the signal produced, in use, by said signal generating means.

    摘要: A radio frequency (RF) coupler transfers RF power between a first circuit on a rotary shaft and a second circuit relative to which the shaft can rotate. The coupler comprises a first RF transmission line arranged to rotate with the rotary shaft about the rotation axis of the rotary shaft for connection to the first circuit and a second RF transmission line relative to which the first RF transmission line can rotate for connection to the second circuit. The first and second RF transmission lines comprise first and second electrically conductive tracks arranged coaxially around the rotation axis in mutually overlapping relationship to provide RF coupling between the first and second RF transmission lines. Each track has a gap defining a pair of ports. One of the ports of each track is connectable to a respective circuit and another port in the track is connected to a RF reflecting termination. A notch filter tunable to a desired frequency within a predetermined RF band is also described.

    摘要: A high speed communication apparatus for a computerized axial tomography (CAT) scanner utilizes large diameter slip rings to permit continuous rotation of a rotatable gantry. A communication signal is applied at a first point on one slip ring, and is terminated by a resistive termination at a point 180.degree. opposite the driving point. The communication signal may then be received at any point on the slip ring. The drive and termination connections to the slip ring may be made by brushes, with the receive connection being made by a physical connection to the slip ring. Alternately, the drive and terminate connection may be made by physical contact, with the receive connection being made by a brush.
