After having divested his company, Olsson continued within the electronics field on a consultancy basis. In Sweden he is well known within the electronics community for his series of articles, called "Olsson's tips" that were written in an educative and personal style, in the electronics branch media magazines "Modern Elektronik" and "Elektronik i Norden". During his last productive years he spent much time on his own theory about the origination of the universe that he termed the "Slow Start" (compare "Big Bang"). His main argument was that the Slow Start theory explains the spectral red-shift, that according to the [[Big Bang]] theory is caused by an expanding universe, in a simpler manner by instead assuming that time itself slowly accelerates.

alt=|miniatyr|Baksidan på en broschyr för Bengt G. Olssons konsultföretag "Inventor, Inc.", som var verksamt i New York, USA, i början av 1960-talet. Bengt Gustaf Olsson, born May 6 1924 in the parish of Steneby in Dalsland, Sweden, and dead April 4 2015 in Stockholm, Sweden, was a swedish electrical engineer och entrepeneur. He was active both in Sweden as well as in the USA as an electrical engineer within analog electronics and as the founder of the Swedish electronics company Xelex AB that provided electronic equipment for professional use as well as HiFi equipment for personal use.

Biography

Bengt G. Olsson was born and raised outside the small village of Dals Långed in the landscape of Dalsland that constitutes a rural part of western Sweden. His parents were Martin Olsson, descendant from Blekinge and a teacher of an elementary school, and his wife Ester, born Löfgren and descendant from Småland. He studied electrical engineering and electronics at the Chalmers University of Technology in Gothenburg and took his Master of Science degree in 1949. During the 1950ths he divided his time mainly between the two large swedish companies ASEA (now part of ABB) and LM Ericsson, before moving to New York, USA in 1959. In New York he worked in various engineering positions within microwave technology, power supply and space electronics. He also had his own consultancy business under the profound name "Inventor, Inc.". In this role he for example helped starting up Data Devices Corporation which first product was based on an invention of Olsson.[a]

After moving back to Sweden in 1964 he founded the company "Xelex AB" that during more than two decades supplied electronic products, mainly for the B2B segment but also in less extent to private persons. Bengt G. Olsson have a number of patents within such different areas as transistor amplifiers [2], heat regulation [3], to sailing ships [4]. Within amplifier theory, he was advocating negative feedback as an important mechanism for linearity of amplifiers.[5]. He also debated the effect of Transient Intermodulation Distorsion (TIM) in an important contribution to Audio Engineering Society (AES) 56th convent in Paris 1977, named "Critical review of the TIM (Transient Intermodulation Distortion) theory". [6][b]

After having divested his company, Olsson continued within the electronics field on a consultancy basis. In Sweden he is well known within the electronics community for his series of articles, called "Olsson's tips" that were written in an educative and personal style, in the electronics branch media magazines "Modern Elektronik" and "Elektronik i Norden". During his last productive years he spent much time on his own theory about the origination of the universe that he termed the "Slow Start" (compare "Big Bang"). His main argument was that the Slow Start theory explains the spectral red-shift, that according to the Big Bang theory is caused by an expanding universe, in a simpler manner by instead assuming that time itself slowly accelerates.

Bengt G. Olsson was in 1960 elected as a senior member of the Institute of Radio Engineers (later IEEE).

"Ingenjörsfirman Xelex AB" (Engineering firm Xelex Inc) was founded 1964 by Bengt G. Olsson. The company was situated in various sites of southern Stockholm during the 1960s, 1970s and 1980s.


Tidigt gjorde man för tiden avancerad transistoriserad mätutrustning[7]. Produkterna utgjordes senare delvis av beställningsarbeten från offentliga och privata institutioner och företag, såsom telematerial till LM Ericsson och DC/AC omvandlare för avbrottsfri kraftförsörjning[8]. Man hade även ett antal standardprodukter som operationsförstärkare [c], stabiliserade likriktare, DC/DC omvandlare och laboratorieaggregat. Den andra stora grenen av produkter var för ljuddistribution och audioproduktion. En känd produkt var effektsteget DD-10 som kunde återfinnas i många musiklokaler. Xelex produkter var välkända för sin pålitlighet och robusta byggsätt[9]Template:Anmärkning. En slogan de använde i en reklambroschyr på 70-talet var att "om man tappar en Xelex förstärkare i golvet, så är det snarare golvet som tar skada". Till kunderna för audioutrustning kunde bland annat Sveriges Radio[8], Norsk rikskringkasting[10] och Kulturhuset i Stockholm[8] räknas.

Xelex avyttrades 1985 till Datatronic AB[11] och Bengt G. Olsson kvarstannade ett kort tag som konsult. Namnet ändrades till ”Xelex Elektronik AB” och inriktningen ändrades till att utveckla och tillverka bland annat utrustning för satellitmottagning till privatpersoner (Handic Elektronik AB "Allemansparabolen"). Efter Datatronics förvärv av Victor Technologies, Inc., ett amerikanskt bolag som tillverkade kalkylatorer och datorer, tillverkades även handdatorer av Xelex. De ansvarade också för produktion av Victors M-serie av datorer. Tandy Corporation köpte 1989 upp Victor och Xelex verksamhet upphörde 1990. Namnet "Xelex" har senare under 2000-talet använts av den f d svenska chiptillverkaren Xelerated, men denna verksamhet har inget med det ursprungliga Xelex att göra[12].
