Feb. '04 Copper - Something New Under the Sun? Copper, its many compounds and alloys are continually being researched, and new developments surface daily. But where do you find out what's new? Scientific journals, sure, but some of the richest sources are the many patents published worldwide. Fortunately, almost all patents are now available online. Here's how to access them.
Apr. '02 Power Quality in Your "Electronic" Home Proliferation of sensitive devices makes good electrical power a must-have. We're using more electricity in our homes every year, but we're also using electricity in ways that didn't even exist 20 years ago. Whether in new homes or old, electrical wiring systems must take these new uses into account.
Sep. '01 Die-Cast Copper Motor Rotors Heading for Success A look a the on-going research designed to take advantage of copper's high conductivity in such a way as to enable the creation of ultrahigh-efficiency electric motors being conducted by an industry-government consortium of which the Copper Development Association (CDA) is a member.

Dec. '98 Alloy 171 for Electronic Interconnects Copper-based materials, with its combination of inherent excellent conductivity, formability and spring characteristics make them strategic materials to the connector industry.
Dec. '98 Q & A With Hans-Erhard Reiter of the ADSL Forum ADSL (Asymmetrical Digital Subscriber Line) is a technology that enables ordinary voice-grade copper telephone wires to also carry high-speed data traffic. Q&A covers ADSL Forum and technology.
Jul. '98 xDSL Technology & The Internet (Part II) A discussion by Marc J. Zionts, CEO, Westell, Inc. on xDSL, a technology which enables ordinary voice-grade copper telephone wires to carry high-speed data traffic as well as telephone calls, thus obviating the need for expensive system upgrades. Includes press release information on telephone company local loop equipment technologies company.
May. '98 The Evolution of Telephone Cable In 1877 Thomas Doolittle developed the process for hard drawn copper wire in the Naugatuck Valley of Connecticut. He had soft, annealed copper wire drawn through a series of dies in order to increase its tensile strength. The hard drawn copper wire was strong enough for overhead wires and copper took over the telephone wire market.
Apr. '98 Home Automation Comes of Age: The Future Has Finally Arrived! Faster computers, more bandwidth and other innovations in the PC are leading to the advent of the truly automatic home. Today's version typically supports interactive voice, data, video, and multimedia, with access to high-performance cabling and interconnection to telephone, cable TV, digital satellite, cellular telephone, and utility telemetry services.
Apr. '98 xDSL Technology and The Internet (Part I) A look at xDSL, which enables ordinary voice-grade copper telephone wires to carry high-speed data traffic as well as telephone calls, thus obviating the need for expensive system upgrades.
Apr. '98 Communications Wiring For Today's Homes New houses and other residential structures are starting to be wired with the cable used for computer networking, called Category 5 (Cat 5) cable, which has the ability to handle tremendous amounts of data and allows many devices to operate over the same cable. New copper based cabling coming onto the applications and should be sufficient to residential data needs for the foreseeable future.
