Filed:

Mar 9, 2005

Appl. No.:

11/077294

Inventors:

Young Joon Kim - Greenfield MA, US
Jun Hong Yi - Greenfield MA, US
James E. Zellmann - Montague MA, US

Assignee:

Judd Wire, Inc. - Turners Falls MA

International Classification:

H01B 7/00

US Classification:

174110R

Abstract:

Lightweight composite electrical conductors made up of a plastic matrix or plastic core, a plurality of electrical conductors either embedded within the plastic matrix or circumferentially surrounding an outer surface of the plastic core, and at least one insulating layer, as well as, cables incorporating one or more of these conductors, are provided. The inventive composite conductors and cables are particularly useful for automotive and aircraft wire and cable.

Assignee:

Judd Wire, Inc. - Turners Falls MA

International Classification:

G02B 6/44

US Classification:

385100, 385126, 385128, 385113

Abstract:

A low smoke, low toxicity fiber optic cable that provides an intermediate surface that facilitates bonding to optical connectors such as LC connectors, is provided. In a preferred embodiment, the inventive cable exhibits improved dimensional stability by minimizing or eliminating shrinkage stress on the optic fiber core.

Appl. No.:

12/964499

Inventors:

Jeffrey Sandsmark Bottman - Seattle WA, US
Jun Ho Yi - Bothell WA, US

Assignee:

Fluke Corporation - Everett WA

International Classification:

G01R 27/28
G01R 31/08
H01H 31/02

US Classification:

324627, 324527, 324555

Abstract:

AC shield continuity for shielded twisted pair structured datacomm cable is determined by testing the cable, driven in a common mode, over a range of frequencies, to determine presence and location of shield breaks. DC ground path generated false results are thereby avoided.

Appl. No.:

10/124896

Inventors:

Young Kim - Greenfield MA, US
Zeng Wan - Greenfield MA, US
Jun Yi - Greenfield MA, US

International Classification:

H01B017/00

US Classification:

174/14900R

Abstract:

A multi-layer insulation system for electrical conductors, an insulated electrical conductor, a process for preparing an insulated conductor, and an insulated conductor prepared by such a process are provided. The insulated electrical conductors are lightweight, qualify for temperature ratings of up to approximately 230 C., and demonstrate mechanical durability and hydrolysis resistance. As such, these insulated conductors are particularly useful for aircraft wire and cable.
