Hans Karlsson was involved in IEEE and Computer Society Standards Activities for more than a decade. He chaired the highly successful family of 1301 Metric Mechanical Standards for Microcomputers, was an active member of the IEEE Microprocessor Standards Committee, and was vice chair of the IEEE Bus Architecture Standards Committee. He had been nominated for the IEEE Standards Board for 1993.
Karlsson is survived by his wife, Agneta. and two grown children, Peter and Pia. The funeral was held in Sodertalje. Sweden. September 11, 1992.
Karlsson was manager of Strategic Partnering, Products and Technology for L.M. Ericsson in Stockholm.

"Hans was commanding yet not demanding"
"His sensitive, people-oriented approach to management enabled him to achieve consensus on the 1301 standards in record time."
"In many ways, Hans' vision of obtaining results has set a new high-water mark in creating standards documetns."
"Hans was the leader of all mechanical activity within the Bus Architecture Standards Committee. Han was a very strong leader with a soft touch. Much like a gentle giant (Hans was a very large man), Hans was imposing in stature, but readily approachable, easy to talk to, and an expert in his field.
"Hans Karlsson chaired some working groups that Futurebus (IEEE 896) and Scalable Coherent Interface (IEEE 1596) relied on for their mechanical packaging (crates and modules).
"Hans Karlsson and I had what I would call a "competitive" relationship.
And than there was Futurebus+, an opportunity for metrification and Hans Karlsson ready to change the historical established 19inch electronics packaging world to a pure metric equipment practice called Hard Metric versus a Soft Metric inch conversion.
Hans Anders Rudolf Karlsson was born in Gothenburg, Sweden on November 3, 1942. He received his engineering degree at Tekniska Gymnasiet in Gothenburg in May 1963. In November of 1964, after military service, Hans began his accomplished career working in the mobile radio laboratory at AGA developing a telephone exchange and later developing and implementing the use of an automatic mobile radio telephone system at the request of the local energy authority of Stockholm. Between the years 1967 and 1971 he was in charge of designing an interface between a blood analysis machine, "the auto chemist" and digital PDP computers. It was during this time that he became interested in computers as a hobby and started designing and building his first computer.
In November of 1971 Karlsson began his employment with Ericsson and later for the Ericsson subsidiary, EPA in Melbourne, Australia, where he developed the computer controlled telex exchange, APB-10, as well as the control system, APN 162. Much of his involvement in the controls systems APN 162 consisted of developing agreements leading to standardization of basic features. His work at Ericsson also involved designing semiconductor Ram cards, producing CPU and bus specifications and design involving computer controlled systems, multiplexors and data links. Between 1978 and 1984, Karlsson was a special consultant for writing specifications in the computer standards field, leading several projects. During this time he also led a Mekan group, tough courses on computer structures and the VME bus and participated in many IEEE Standards projects.
After becoming a Section Head at Ericsson, he was responsible for both internal and external relations, working with both hardware and software development of standard computer systems and platforms. In 1984, Karlsson become senior advisor at Ericsson, where he was responsible for international business contacts regarding connectors and the associated hardware. He taught several courses in Sweden on the system construction for APN 167 as well as in Australia on the microcomputer field.
In addition to his accomplished career, Karlsson was involved with many committees beginning in 1981 including IEEE, IEC, ETSI, ESONE and TCI/IEC/TCO. In 1989 he became the chairman for these standards setting committees, vice chairman for the international affairs for IEEE Bus Architectures Standards Committee, and Liaison Officer for ETSI-IEEE in both organizations.
To highlight his career, Karlsson received numerous awards to acknowledge his accomplishments including the Quality Prize, for successful interactive work with companies within the United States, and the IEEE Outstanding Contribution Award for, "outstanding leadership in the development of the IEEE 1301 Metric Mechanical Specification," dedicated to him in 1990.
Hans Karlsson, self confident since childhood, was a charismatic, infectiously enthusiastic, energetic, kind man, whose personality and determination led him to results. Though his traveling was extensive and the results desirable, his family, wife Agneta, son Peter, and daughter Pia remained center of his considerations.
"I do not want to lose what I tackle. That is what makes me work for results."
