Patent number: 10033074Abstract: The present invention provides improved non-contacting rotary joints for the transmission of electrical signals across an interface defined between two relatively-movable members. The improved non-contacting rotary joints broadly include: a signal source (A) operatively arranged to provide a high-speed digital data output signal; a controlled-impedance differential transmission line (C) having a source gap (D) and a termination gap (E); a power divider (B) operatively arranged to receive the high-speed digital data output signal from the signal source, and to supply it to the source gap of the controlled-impedance differential line; a near-field probe (G) arranged in spaced relation to the transmission line for receiving a signal transmitted across the interface; and receiving electronics (H) operatively arranged to receive the signal received by the probe; and wherein the rotary joint exhibits an ultra-wide bandwidth frequency response capability up to 40 GHz.Type: GrantFiled: December 9, 2014Date of Patent: July 24, 2018Assignee: Moog Inc.Inventor: Donnie S.

Patent number: 9306353Abstract: An improved slip-ring has a stator and a rotor, and includes a brush having a proximal end mounted on one of the stator and rotor and having a distal end engaging the other of the stator and rotor. The brush is adapted to convey electrical signals across the interface between the stator and rotor. The improvement includes: the rotor including a support member (1); and a track provided on the other of the stator and rotor, the track being arranged for sliding contact with the brush distal end; and a thermal element (3 or 6) arranged within the support member for selectively affecting the temperature of the rotor; whereby the temperature operating range of the slip-ring may be increased.Type: GrantFiled: May 29, 2013Date of Patent: April 5, 2016Assignee: Moog Inc.Inventors: Donnie S. Coleman, Michael H. Harris, Terry A. Willemin

Patent number: 8283993Abstract: A twist capsule (10) broadly includes: a flexible tape (13), and a pre-emphasis circuit (11) operatively associated with said tape to compensate for attenuation of high-frequency digital waveform constituents attributable to skin effect and/or dielectric loss, such that the operational bandwidth of signal transmitted over said tape may be increased. An equalization circuit (14) may be arranged at the output end of the tape to further extend the operational bandwidth.Type: GrantFiled: September 18, 2008Date of Patent: October 9, 2012Assignee: Moog Inc.Inventor: Donnie S.

Patent number: 7559767Abstract: A drum-style slip-ring module (100) is used in a contact-type communication system. The module utilizes PCB construction to construct a plurality of stacked electrically-conductive rings (102) and a plurality of dielectric layers (104) electrically isolating the conductive rings. Each of the dielectric layers includes a centrally-located aperture (107). The module also includes a cylindrical ground plane (108) positioned in the centrally-located aperture. The module is configured to provide electrical connection to each of the rings at an exterior surface of the module. Each group of feed line vias can be designed as impedance-controlled transmission lines with connections to each ring group. The construction described in this invention can create slip-ring transmission line structures with bandwidth from DC to 5 GHz or higher, allowing the slip-ring to be used to transfer multi-gigabit digital data streams.Type: GrantFiled: May 15, 2007Date of Patent: July 14, 2009Assignee: Moog Inc.Inventors: Donnie S. Coleman, Jack T. Galyean

Patent number: 7142071Abstract: A velocity compensated contacting ring system includes a first dielectric material, a plurality of concentric spaced conductive rings and a first ground plane. The first dielectric material includes a first side and a second side. The plurality of concentric spaced conductive rings are located on the first side of the first dielectric material. The conductive rings include an inner ring and an outer ring. The first ground plane is located on the second side of the first dielectric material. A width of the inner ring is greater than a width of the outer ring and the widths of the inner and outer rings are selected to substantially equalize electrical lengths of the inner and outer rings.Type: GrantFiled: July 29, 2005Date of Patent: November 28, 2006Assignee: Moog Inc.Inventor: Donnie S.
