Patent number: 11936415Abstract: An air interface plane (AIP) of a radio frequency (RF) aperture includes: a circuit board having a first side and a second side opposite the first side; and a matrix of tapered elements arranged on the first side of the circuit board and secured to the circuit board, the matrix of tapered elements cooperating to at least one of receive or transmit an over-the-air RF signal. Suitably, each tapered element of the matrix has: a central hub extending along a longitudinal axis from a hub base which is proximate to the first side of the circuit board to an apex of the tapered element which is distal from the first side of the first circuit board; and a plurality of arms extending from the central hub at the apex of the tapered element, each of the plurality of arms including a first portion that projects the arm radially away from the longitudinal axis and a second portion that projects the arm longitudinally toward the first side of the circuit board.Type: GrantFiled: April 26, 2023Date of Patent: March 19, 2024Assignee: BATTELLE MEMORIAL INSTITUTEInventors: Raphael Joseph Welsh, Douglas A.

Patent number: 9601239Abstract: Systems and methods for decreasing alien crosstalk use enhanced patch cords for introducing additional attenuation. The enhanced patch cords are preferably shielded to reduce alien crosstalk down their lengths and also attenuate signals passing therethrough to a greater extent than standard communication patch cords. The interaction of two enhanced patch cords results in two suppression steps for alien crosstalk and only one suppression step for intended signal passing through a communication cable.Type: GrantFiled: July 24, 2015Date of Patent: March 21, 2017Assignee: Panduit Corp.Inventors: Ronald A. Nordin, David R. Hawkins, Michael V. Doorhy, Jack D. Tison, Andrew J. Stroede, Masud Bolouri-Saransar, Scott R. Hartman

Patent number: 9029706Abstract: Communication cables are provided in which a core lay length of the cable varies along the cable length. The cable may be provided with different segments that have different core lay lengths. It is desirable for neighboring core lay lengths in a cable to differ by a factor of two, to enable a reduction in power-sum alien near-end crosstalk (PSANEXT) when two cables are installed alongside one another. Segments of the cable having different core lay lengths may be spaced periodically along the length of the cable, and the periodicity of the spacing may be altered by a jitter distance. The introduction of jitter into the periodicity of the spacing of the segments increases the likelihood that a beneficial placement of core lay lengths will occur when two or more cables are installed alongside one another.Type: GrantFiled: August 24, 2012Date of Patent: May 12, 2015Assignee: Panduit Corp.Inventors: Masud Bolouri-Saransar, Michael V.

Patent number: 6766022Abstract: A system for cross-connecting network elements of different types through a common universal media. In the system, a media conversion interface is electrically connected to a network element. This media conversion interface passively maps the connector and cable type of the network element to a universal connector type. This media conversion interface is electrically connected to a cross-connect module in a universal distribution frame. This electrical connection uses a universal cable group and universal connectors. This cross-connect module is connected to another cross-connect module, also in a universal distribution frame, using a universal cable group and universal connectors. This second cross-connect module is electrically connected to a second media conversion interface, using a universal cable group and universal connectors.Type: GrantFiled: September 18, 2000Date of Patent: July 20, 2004Assignee: Avaya Technology Corp.Inventors: Steven C.

Patent number: 6608255Abstract: A cabling media which is suitable for high performance data transmission includes a plurality of insulated metallic conductor-pairs, each pair including two plastic insulated metallic conductors which are twisted together. More specifically, the introduction of a periodic rotation along the length of each insulated conductor essentially acts to cancel out a large number of the adverse effects which may result due to a lack of conductor concentricity and/or dielectric eccentricity.Type: GrantFiled: May 22, 1997Date of Patent: August 19, 2003Assignee: Avaya Technology Corp.Inventors: Daryle Pat Donner, Harold Wayne Friesen, David R.

Patent number: 6452094Abstract: A local area network cable capable of high speed signal transmission has a plurality of twisted pairs of conductors enclosed within a jacket. Each of the twisted pairs has a different twist frequency than any of the other pairs, and at least one of the pairs has a direction of twist that is different from the other twisted pairs, that is, it may have a right hand twist where the other pairs have a left hand twist. In a four pair cable, two of the pairs, of different twist frequency, have imparted thereto a right hand twist, and two of the pairs have a left hand twist.Type: GrantFiled: June 3, 1999Date of Patent: September 17, 2002Assignee: Lucent Technologies Inc.Inventors: Daryle Pat Donner, Harold Wayne Friesen, David R.

Publication number: 20020056568Abstract: A cabling media which is suitable for high performance data transmission includes a plurality of metallic conductors-pairs, each pair including two plastic insulated metallic conductors which are twisted together. The present invention describes how the selection and incorporation of metallic conductors having different diameters within a single communication cable can significantly enhance the operational performance of the cable. More specifically, given a first conductor-pair having a certain conductor diameter and twist length, and at least one other conductor-pair with a different twist length, the present invention purposely selects metallic conductors for this other conductor-pair with a different diameter than that of the first conductor-pair so as to ensure that the insertion loss exhibited by the additional conductor-pair is essentially equal to the insertion loss exhibited by the first conductor-pair.Type: ApplicationFiled: February 26, 2001Publication date: May 16, 2002Inventors: Harold Wayne Friesen, David R. Hawkins, Stephen Taylor Zerbs
