Inventor of AT&T’s Datakit, the First Digital Connection Swap, Dies at 85


Alexander “Sandy” Fraser

Developer of the primary digital circuit community change

Fellow, 85; died 13 June

Fraser developed the Datakit, the primary digital circuit community change, whereas working at AT&T Labs in Florham Park, N.J. The telecommunications know-how is utilized by all main U.S. phone firms.

He invented different pioneering applied sciences as properly, together with the file system for the Titan supercomputer (prototype of Atlas 2), cell-based networks (precursor to asynchronous switch mode), and the Euphony processor, which was one of many first system-on-a-chip microprocessors.

He started his profession at Ferranti, {an electrical} engineering and tools firm in Manchester, England. He left there in 1966 to affix the College of Cambridge as an assistant director of analysis. After three years, he moved to the USA to work for AT&T Bell Labs in Holmdel, N.J. Whereas there, he helped develop the Shifting Image Specialists Group Superior Audio Coder, which compresses music alerts. First utilized in Apple’s iTunes program, it now could be present in all smartphones.

Fraser held a number of management positions on the firm throughout his 30 years there. He grew to become director of the Computing Science Analysis Heart in 1982 and 5 years later was promoted to govt director. In 1994 he grew to become affiliate vp for the corporate’s info science analysis division. In 1996 he helped set up AT&T Labs in Florham Park. It’s the firm’s analysis and growth division, of which he was vp for 2 years.

He determined to focus extra on analysis and left his place as vp. AT&T named him chief scientist, and in that place he labored on creating structure and protocols for a large-scale Web in order that clients might connect with it from their houses.

In 2002 Fraser retired and based Fraser Analysis, in Princeton, N.J., the place he continued his networking work.

He earned his bachelor’s diploma in aeronautical engineering in 1958 from the College of Bristol, in England. He went on to obtain a Ph.D. in computing science in 1969 from Cambridge.

From 1990 to 1993, he labored at AT&T Bell Labs in Murray Hill, N.J., earlier than becoming a member of Texas Devices in Dallas. After one 12 months, he left the corporate and joined Seoul Nationwide College as an assistant professor {of electrical} and laptop engineering. He labored on the college on the time of his loss of life.

His analysis pursuits included the design and fabrication of neuromorphic units and circuits, flash reminiscences, and silicon quantum units.

Park authored or coauthored greater than 1,200 analysis papers. He was granted 107 patents in Korea and 46 U.S. patents.

He acquired bachelor’s and grasp’s levels in electronics engineering from Seoul Nationwide College in 1982 and 1984, respectively, and a Ph.D. in EE in 1990 from Stanford.

David Ellis Hepburn

Previous vice chair of IEEE Canada’s Instructor-in-Service Program

Life senior member, 91; died 25 March

Hepburn was a powerful proponent of preuniversity training and loved serving to form the subsequent era of engineers. He was concerned with IEEE Canada’s Instructor-in-Service Program, an initiative that goals to enhance elementary and secondary college technical training by providing academics lesson plans and coaching workshops. He served as vice chair of this system’s committee. He was honored for his contributions with the 2017 IEEE Canada Presidents’ Make-a-Distinction Award.

He was an energetic volunteer for TryEngineering, an internet site that gives academics, mother and father, and college students with engineering sources. These embrace hands-on classroom actions, lesson plans, and details about engineering careers and college applications. He wrote six classes, which cowl transformers, AC and DC motors, magnetism, binary fundamentals, and solar energy.

Whereas a scholar at Staffordshire College, in England, he was an intern at electrical tools producer English Electrical in Stafford. 5 years after graduating in 1952, he joined utility firm Hydro-Québec in Montreal as a programs design engineer. In 1965 he went to work for consulting agency Acres Worldwide in Montreal. His first task there was with the design and building group for the Churchill Falls underground hydroelectric energy station, in Labrador, Nfld.

In 1969 he was tasked with serving to to construct transmission strains in Bangladesh that related the nation’s jap and western electrical grids. He and his household lived there for 2 years.

After that, Hepburn continued to work on worldwide initiatives in nations together with Indonesia, Nepal, and Pakistan.

Following his retirement in 1994, he labored as a guide for organizations together with the World Financial institution and the Canadian Worldwide Growth Company.
