Patent number: 9831606Abstract: A communication connector including elongated contacts, and an optional flexible compensation circuit. The elongated contacts include a plurality of contact pairs. Each pair includes first and second contacts configured to transmit a differential signal. The elongated contacts may each have first and second portions with first and second heights, respectively. The first height is greater than the second height. The first portion of the first contact is positioned alongside the first portion of the second contact to capacitively couple the first and second contacts together. The optional flexible compensation circuit includes compensation circuitry configured to at least partially reduce crosstalk between the elongated contacts.Type: GrantFiled: November 2, 2016Date of Patent: November 28, 2017Assignee: LEVITON MANUFACTURING CO., INC.Inventors: Jon Clark Riley, Bret Taylor, Charles R.

Patent number: 8182655Abstract: Embodiments of the invention relate to plating systems configured to strip plate a selected portion of a workpiece (e.g., a lead frame) and methods of plating. In one embodiment, a plating system is configured to plate a selected portion of a workpiece and at least partially compensate for wheel run out. As an alternative, or in addition, to the plating system being configured to at least partially compensate for wheel run out, in another embodiment, a plating system is configured to plate the selected portion of the workpiece and provide for controllably adjusting plating dimensions on the selected portion to be plated.Type: GrantFiled: September 4, 2008Date of Patent: May 22, 2012Assignee: Leviton Manufacturing Co., Inc.Inventor: Darrell W.

Patent number: 7278879Abstract: A connector isolation station system includes ports to receive connectors and includes shield members. The shield members have material properties to substantially shield, attenuate, absorb, diminish, or otherwise hinder or at least partially block wireless signals and noise from impinging upon or otherwise interfering with signal transmissions occurring through the connectors located in the connector isolation station. For instance, transmissions through adjacent connectors are substantially prevented from interfering with one another.Type: GrantFiled: February 23, 2006Date of Patent: October 9, 2007Assignee: Leviton Manufacturing Co., Inc.Inventors: Frank Chin-Hwan Kim, Jeffrey P. Seefried, John Redfield, Darrell W. Zielke, Patrick S. McNutt, Phillip Phung
