When I was a kid I was very fond of radio and electronics. When 10 years old, I built a series of radio receivers for my friends. I did my first business selling this "New type of radio, needing no batteries!". (Nobody realized it was the old crystal-radio inside the wooden box!)
When I was12 years old in 1963, I started playing drums. Joined my first band "The King-Bees" in 1964 (left picture) when I was 13. King-Bees was mainly a a pop cover band.
Left to right: me (drums), Bo Vikstrom (bass), Chister Hallberg (lead guitarr), Jan Hallberg (rythm guitarr), Klas Svensson (vocals).
We used to play, and was the "house-band" at the quite rough rockers club "The Comet" in Helsingborg.
When I was 13, I built my first stereo. The amplifier was a 6 watt Heathkit AA-201 Stereo Amplifier in kit form. I also made two open baffle dipole loudspeakers that I had salvaged from two old Blaupunkt Hi-Fi radios. Sounded ok but not too great. I put the speakers on the wall behind my drum-kit and practiced drumming to pop music from my small vinyl collection.
When I was 12 years old I got myself an old Husquarna M71 motorbike (left). This was weak and only 125cc (and 4hp) but was ok for trying out some fun dirt-tracks.
Later, when 15, I did get myself a hot BSA Super Rocket 650cc (right). This was sold cheap to me totally dismantled in all parts, and it took me more than three months to put it all together and tune it to spec. This bike was really flying. I did run it at top speed of 170 km/h! Quite some speed in those days!
As a young teenager I was a bit of a "rebel". I dressed odd in a US Army camouflage jacket and was first in town using high-heel boots (white-painted black boots), and had pierced my ear wearing two ear-rings (quite uncommon in those days).
I had much too long hair (according to the master of my high-school). Sometimes I participated in the riots between rockers and mods. I did not fight however and never got a blue eye, but was more trying to take on a neutral position. I guess the teenagers where frustrated and quite fed-up having not much to do in those days.
In the picture left, I was interviewed by my home-town newspaper during the riots. (I was14 years old)
I experimented in the 1960's as a teenager with shortwave radio communication and RTTY teletype transmissions (at 50 or 45.45 baud). It was quite complicated to build the RTTY FSK-modem in those days. The Creed-7 teletype was difficult to synchronise and a mechanical tuning-fork stroboscope(!) had to be used for rpm adjustment.
I really wanted a Ham radio licence, but could not cope with the mandatory and rather boring Morse code. I was on a low budget and used an old WW2 "Wireless Set-19" as transceiver, and an old Lancaster-bomber receiver, the "R1155".
I started playing drums as an international touring professional in 1967 when I was 16. Shades-of-Blue (left picture) was my first internationally touring soul-band.
We performed mainly in Germany, Denmark and Sweden (and later in Spain). In this photo Tony (top) from Denmark was the lead singer. Later John Max from Jamaica joined as lead singer.
Left to right: Mike Noller (guitarr), Ronny Volt (bass), Jarl Stanley (sax), Tony Lindebjerg (vocals), me (drums) and Dave Oxnard (keyboards).
We recently had the Shades of Blue 2007 "revival concert" in the city of Helsingborg. It was actually possible to get together all group members from all over Europe and play just one more time, 40 years later!.
In 1968, when I was 17, I toured with Shades-of-Blue mainly in Spain. Larry Wald from Rio de Janeiro joined us as the lead singer. Larry had a famous international hit "Mendocino" in 1968.
We did a number of radio shows both for Spain and South America.
Left to right: Bert Moller (baryton sax), Bernd Seibt (Hammond), Mike Noller (guitarr), Berney Smidt (sax), me (drums), Larry Wald (vocals) and Goran Svensson (bass).
When having some spare time in 1968 (and not playing drums with Shades-of-Blue), I got the job as the gocart boss at Motel Avion's gocart track. This was one of two large gocart tracks in Madrid. I was repairing, tuning and rebuilding various types of gocarts, when not supervising visiting drivers.
The pay was really bad, but I got unlimited free fuel for my own gocart. Therefore I could practice gocart driving all day long with my quite hot italian competition gocart. This was really great, great fun!
I joined Lena-Maria and Sweet Wine in 1969, this was a internationally touring pop, rythm & blues band.
We where touring Scandinavia, United Kingdom, the Netherlands and later mainly in Spain.
We did cut some singles and LP's and did the well known "Jesus Christ Superstar" tour in Sweden 1972 (although none was particularly religious).
When touring Spain in 1970, both Ernie Garret and famous singer Vin Cardinal joined Sweet Wine as singers together with Lena-Maria.
Left to right: Lennart (trumpet), John Blincoe (sax), Dougie Lawton (guitar), Bengt Kihlstrom (hammond), Lena-Maria Gardenas (vocals), me (drums), Gert Sandin (bass).
In 1971, when I was 20, I started my first company "Stocktronics". I toured around Sweden and northern Europe and did rebuild Hammond organs (left picture) for various artists in order to improve the Hammond organ sound-quality (by just snipping off some LP-filter capacitors in the amplifiers). The sound result was stunning, and the work took only about 30 minutes, thus quite easy earned money! :-)
I also designed and sold some high-power "Sound-modulated light Colour-organs" and polarized-light projectors for various Swedish and international discotheques. But a serious power black-out (not my fault..) of the famous "S:t Peppers" disco in Palma de Mallorca somewhat ended my career in this field... :-(
In 1972, I moved to Stockholm. In my spare time I experimented in psychophysiology with my own developed EEG brain-wave neurofeedback monitor for alpha-wave feedback (left). This is a de-stressing device using self-regulation to steer you into a relaxed state by increasing your brains alpha waves.
I also got myself an old Siemens 8-channel Mingograph EEG recorder to register human brain activity and a Cardiorex 12-channel ECG recorder (right) for cardiac evaluations (both with messy ink-galvos!). .
Numerous friends, male and female, was tested in "various situations" ;-) with EEG and ECG electrodes strapped to them. This was great fun and very interesting.
My friends thought I was totally nuts, having such strange interests.....
Finally in 1973 Sweet Wine had a Top-10 number one hit in Sweden,"Hideaway"! Our hit had the1993 record of being placed on the hitlist for altogether 5 weeks! This was quite an achivement. This resulted in numerous TV and radio programs. Lena-Maria also started her own TV-show.
Lena-Maria's husband Dougie Lawton produced "Hidaway" and the follow-up LP-record, and I did the 24-track recording/mixing at Studio DeciBel in Stockholm (see below).
Left to right: Erik Strandh (hammond), me (drums), Lena-Maria Gårdenäs Lawton (vocals), Dougie Lawton (guitar), Lennart Lilliengren (bass).
I freelanced 6 years as a 24-channel multitrack recording engineer, mainly working at Studio DeciBel in Stockholm. I started out as an 8-track engineer in 1972 and continued as 24-track engineer when the new MCI 24-track recorder was installed in 1973. I made 2 gold labels and 3 silver labels during this period. My work contributed to quite a number of internationally distributed records.
Lab Electronics designed the, at the time, very advanced recording/mixing console. This had overload protected VCA mic-amps and gyrator sweep-equalizers as well as flurocent engraved text and markers. The control room, when lit by a flurocent light, looked like a 747 cockpit.
I also did early video productions with my own (analog) video cameras and 1" tape-based video recorders. Did also PA-system mixing jobs for live conserts like various performances at the Stockholm Concert Hall, Stockholm Jazz Festival, The Waxholm Festival and many other performances and festivals. Quite fun!
In the early synthesizer days I worked parttime as a synthesizer programmer, mainly programming early Moog Modular and EMS synths, but also a little with the Buchla synth. This was in those days mainly involving setting up the synths for different artists performances and module programming using cables or by programming a matrix field. Quite different from todays software programmable plug-in synths!
My favorite "old-timer" synth replica today is the amazing Arturia Moog Modular V2 plug-in.
In 1973 I got myself a Neumann disk-cutting lathe. This was used to cut laquer masters for the vinyl-disk mastering process. The Neumann SX-68 stereo disc cutter head was helium-cooled for extended power handling. The disk-cutting amplifiers was the famous Neumann VMS-66 valve amplifiers as used when cutting the super-drummer Billy Cobham masters. Additional equipment was an Ortofon STL632 acceleration limiter to keep treble energy and trace acceleration distortion down, and a Telefunken M10 preview tape recorder for the trace preview servo and master tape playback. I built the mastering control console myself using high slew-rate, low-noise op-amps.
In 1983 when the CD was introduced, I sold the Neumann lathe to a crazy japanese audiophile who converted the cutting lathe to a "super grammophone" for vinyl record playback! Severe audiophilia madness!
In 1962 the first LASER producing continous visible light was invented.
In 1971 I built my own 5 mW (red, 632.8 nm) Helium-Neon LASER (left picture) and got quite surprised and fascinated by the peculiar "speckle pattern" appearance and behaviour from the reflected LASER light.
I designed and built my own electrodynamic X-Y laserbeam scanner unit and an analog Lissajous pattern computer so I could display interesting LASER-videopatterns art on a wall or screen.
Together with a friend who played musical "drones" with a Hammond organ and a saxophone, we exhibited "Drone-Lissajous LASER video-art" in the early 1970's at the Stockholm Museum of Modern Art. I seriously belive that this was the first LASER-show ever in Sweden.
I did also build a monochromatic video projector where three surplus IBM acoustooptic modulators deflected my laser beam in X and Y and modulated the intensity in Z and all was driven from an old analog TV. Picture quality was very bad but it actually worked!
I have recently started up my "LASER revival project" where I have duplicated my old LASER-art show, but using a modern 250 mW green Diod-Pumped Solid-State laser and closed-loop X-Y galvanometer scanners, and my old analog Lissajous computer.
(Home-built Laser and X-Y scanner-board left, and my old Analog Lissajous computer right)
Some Lissajous-patterns left .
For Laserists: The analog Lissajous computer is directly feeding the analog ILDA input terminals on the galvanometer driver boards, X and Y.
My Lissajous computer contains 8 signal generators, 2 multipliers and 2 phase-shifters.
I also have a high-power green DPSS laser for large-scale laser art display. I recently got a special permit from the Swedish Radiation Safety Authority for laser projections outdoors. Regulations are very strict in Sweden and I have installed multiple safety measures like electronic beam-clipping and double "spade shutters" (left picture) to enhance beam safety.
I use the "PHOENIX ShowController" software and 60k pps CT-6210 closed-loop galvanometer scanners for projecting X-mas moving picture greetings on the water-tower on the other side of the channel.
In 1974 when I was 23, I filed my first patent. My invention was a LASER interferometer (auto refractor) for refraction measurements of the human eye (automatic eye examination using no trial lenses and no letter-tables).
The principle behind the invention was based on "speckle pattern" interference movement, that was compared/measured automatically and passively at the observers position.
Of course this my first patent never made it commercially! About 10 years later somebody else nicked my basic idea, and sold their LASER eye-refractor examination apparatus to opthalmologists worldwide. Grrrr...
In 1976 I joined the well established and famous Swedish dance-band "The Moonlighters". We where mainly touring Swedish "folk-parks" and dance-restaurants. The pay was good but the repertoire was quite boring dance-music.
The Moonlighters had many musicians coming and going even during my time in this band, and many respected musicians has passed through the band during the years.
During my time in the band we had a hit in the Swedish Radio hit-parade "Svensktoppen" with a song named "Sommaren behover vi". We made one LP and some singles. We closed down the band for good in 1980. Yeah!
A late, small configuration of the Moonlighters, from left to right: Basse Wickman (vocals and guitarr), me (drums), Jan Brathe (bass), Johnny Blomqvist (keyboards and vocals).
Yes (belive it or not), in the late 70's I was (once) a photo-model! (pictures left)
My first Jeep (green in the pictures) was a Willys Jeep CJ-2A, with a Volvo B20 engine, tuned with high-compression head, high-torque camshaft and natrium-cooled exhaust valves(!).
I did some off-road competition and rebuilt it with heavy-duty Dana-44 axles front and rear, limited-slip differential and of course 40" large Monster Mudders!
Later, I got myself another more heavy-duty Jeep, the CJ-5 with a large high-torque engine.
In the late 70's I developed a stereo reverberation plate, the RX4000. Artificial reverberation units are used in recording studios to create a spatial church-like reverberant sound-effect. Today such units are digital, but in the earlier days reverberation units where always mechanical like chambers, springs or plates. My unit was unique due to its thin (0.3mm) and extremely flat stainless steel plate. The hardness of the stainless steel gave the RX4000 extended high-frequency reverberation time, making it sound sizzling bright.
My world-wide agents (Japan brochure left) sold more than 250 units to many famous customers like live performing artists, recording studios, record companies and film/video studios all over the world, like ABBA, the Police, Tamla Motown etc. It can still be found in use today, and sometimes for sale on the Internet.
The RX4000 was tested and evaluated positively in international magazines for the sound and recording industry, and in particular positively by the recording industry legend Mr John Voram.
A DEEP-DIVER COMMUNICATION SYSTEM
In the mid 1980's I developed the world's most advanced deep-diver communication system for the offshore oil-industry. Part of this work was funded by the Swedish Navy and various international oil companies like Statoil, Norsk Hydro and British Petroleum (BP) etc.
The Stocktronics Deep-Diver Communication System set world standards in this field, and was mandatory for deep-diving operations deeper than 180 meters in the oil-fields of the North Sea.
A number of large installations was delivered worldwide to semi-submersible diving platforms, monohull diving ships and shore-based diving laboratories. Some systems are still in use today world-wide.
My system enabled for the first time ever, deep-diving (Donald Duck-sounding), helium-breathing divers in saturation, to speak fully unscrambled with a normal voice, in full duplex with each other, with crane-operators etc, and even speak unscrambled over the phone with their wifes at home.
This system supports very complex traffic situations with multichannel communication between occupants, isolated or in "round-robin".
The advanced unscrambler use frequency-domain signal processing similar to homomorphic-deconvolution for accurate voice unscrambling.

Top left to right: MSV Karinia, MSV Regalia, DSV Norskald.
Bottom left to right: Naval Diving Centre Stockholm, DSV L376 Mingazprom Russia, Comex Hyperbaric Centre, Marseille.
My communication system was also recommended by ESA (The European Space Agency) for use in experimental earth-born space habitats.
In 1989 I was awarded the prestigous "Ocean Technology Price" for my Deep Diver Communication System and Helium Speech Unscrambler. This was given to me by the Swedish Board for Technical Development (STU) and the Swedish Ocean Industry Group (Swedocean).
The award was given to honor "Creativity, technical skill and persistence, leading to great success both technically and in business, in hard international competition, reflecting comprehensive, systematic and trendsetting development of a Deep Diver Communication System"
I started boating early with with my small 29 ft motorsailer and got myself a commercial captains licence, and ships engineers license. However when sailing, the wind always came from the wrong direction, so I got fed-up with sailing and got myself a motor yacht instead in 1989.
This was a dutch Vitsen & Vis 55 ft steel yacht (built for Mr Conrad Hilton in 1966). I sailed her with my family from south of Spain to Sweden and that was quite a rough adventure, reflecting the bad weather and rather low technical state of the boat (many engine and genset black-outs).
I had great fun when I got a contract with the Swedish Costal Defence participating in some anti-submarine hunting operations during the period of Russian paranoia. I fitted out the boat with my own high-sensitive hydrophones and passive sonar surveillance equipment.
Here I participated in a hot "DEFCON-2" (all submarine mine-stations armed!) submarine hunt as mother-ship to a new "unknown" type of mini-sub (left).
Three proud and successful captains, Captain "me", Captain Hellas, Swedish Civilian Defence and Captain Bertil Roland (retired) Swedish Navy.
Despite 800 active and alert Swedish Navy and Costal Defence personnel in the submarine hunting operation, I was the only one who managed (by obvious reasons) to get a sonar sound signature from this new mini-sub. After the submarine hunt, our sound-signature DAT-tape recording of the new sub was urgently picked up by a Navy chopper and delivered to the Swedish Navy ship signature analysis centre MUSAC.
Some of the analysis equipment onboard (left), a B.K real-time analyzer, a B.K. third-octave filter, a PC-based LOFAR spectrum analyzer, and (not in the picture) a 10k-tap Adaptive Line-Enhancer filter (ALE) for ambient noise reduction and submarine signature enhancement (developed by me and a British consultant). The ALE use a powerful Texas 320C30 Digital Signal Processor (DSP).
As I was involved in the above activities I also had the opportunity to participate in submarine hunt operations as a mini-sub passenger.
This was quite exiting, laying still at the bottom or moving quietly sub-sea at slow speed with a mini-sub, hearing the hunter ships chasing around above trying to find us with their sonars.
The mini-sub used, was the famous Swedish Navy "Spiggen mini-submarine" (left picture).
I also developed and marketed a portable high-sensitive, low-noise capacitive hydrophone system, the ASW-1, for the Swedish Navy, the Costal Defence and others. This became very popular and could easily detect submarines and in particular ships at many miles of distance.
It was so sensitive so in a calm seastate, you could even hear fish communicate with their "quirking" sounds. I demonstrated this in a short television news programme.
As the old 55 ft steel lady was getting a bit too rusty, I sold her and got myself a nice Hatteras-58 glass-fiber yacht instead. She had two grand V-12 Detroit Diesel engines of 1000 hp and did up to 18 knots speed.
She was previously owned by the whiskey destillery Jack Daniels and had been very well looked after during the years in Ft Lauderdale. I sailed her with my family in Florida, Bahamas and northern Europe. (left picture).
She has also been used for my underwater technical development projects and as a platform for my high-resolution side-scan sonar for exciting wreck hunting activities (see below).
Me and Fredrik Henn (a colleague) developed in 1994 a high-power hydroacoustic communication system. Such unit is used for submarines, underwater diving-bells and habitats to communicate through the water with other units or surface ships. In our first real test we had excellent communication over 5.000 meters through the water, far better than many military or commercial systems (left picture). Read this OFFSHORE article (pdf)
One of my hobbies is underwater wreck-hunting using side-scan sonar. A side-scan sonar picture is seen at the left monitor and my electronic chart system is seen at the right monitor (right picture).
I have two EdgeTech 272TD (100/500 kHz) side-scan sonars and a Sea Labs (200 kHz) side-scan sonar for ship-wreck hunting.
This is a stunning side-scan sonar picture showing the quality of the EdgeTech 272TD sonar transducers.
The 500 kHz transducer was used for recording this image of the 124 m German ship "Fritzen" at 75 m of depth. The 100 kHz transducer offers longer swath scans but less detail.
The Sea-Labs side-scan sonar was designed by my good friend and sonar expert Sture Hultqvist. He unfortunately passed away at a much too young age.
In 1995 I started up a research project (according to a request from my friend Lars Molinder) and a feasibility study to develop a highly advanced digital binaural hearing-aid, the DHS (Digital Hearing System). The DHS project was funded mainly by national government institutions. Fredrik Henn and me learned a lot from this project study, but in 1997 the project was closed down due to lack of funding.
In late 1997 however, we got the offer to start up the DHS project again with substantial funding from major investors. But I had then allready started up a new R&D project (SBR) and a new company around this, Coding Technologies (see below), so due to lack of manpower the DHS project was closed down.
If you are interested to read about some of the early premature DHS project ideas, click this DHS link (pdf).
The least successful idea and invention I did was my first patent in LASER interferometry filed in 1974 (above). The most successful idea I have thought-up is the idea that led to the invention of SBR (Spectral Band Replication) used for improving audio-codecs, with my patent filed in 1997. Note that this is around 23 years later! Not easy being an inventor.....
I started up Coding Technologies in 1997 due to my innovative SBR idea. My clever engineers and colleagues helped me develop something great out of this. This resulted in a successful international company with our products used worldwide in Radio and TV, satellites, mobile phones, radios, PC's, and consumer electronic devices etc. Read this fun interview (pdf)
My SBR idea is based on the concept of "spectral redundancy" in the frequency-domain, that is, the signal spectrum harmonics often looks-alike in both the lower and higher frequences. Therefore it is not necessary to transmit all the spectral information all the way up to the high-frequencies. Instead you transmit a limited frequency range to the decoder and thereafter transpose the low frequencies at the decoder up to the high-frequency range and apply just a little side-information from the encoder to tell how the high-band should look like at the decoder. (See left picture as used in my first patent search early 1997). This method saves a lot of data, resulting in up to 50% coding efficiency improvement. Read this AES paper on SBR (pdf)
One can simply compare the concept of SBR to a "turbo", that can improve the performance of any audio-codec "engine" (for example the AAC). As a result you get a "turbo-charged" codec. AAC becomes the HE-AAC.
I also initiated the idea and development of Parametric Stereo (PS), a method somewhat similar to SBR, but instead representing sparse coding in the spatial domain. In the PS simplest form, you only need to transmit a mono channel (and SBR) and some limited side-information on how the stereo perspective should look like. This saves additional information resulting in the highest coding efficincy available anywhere. Read this AES paper on PS (pdf).
The aacPlus V2 (HE-AAC) codec is now standardized by ISO-MPEG and offers good-quality stereo at an incredible low 24 kbps, and close to CD-quality at 64 kbps!
SBR is the established de-facto enhancement technology for broadcast and streaming codecs and SBR has been estimated to be deployed in more than 6 billion devices(!), from consumer electronic, to professional broadcast equipment.
New spin-off´s are the extremely efficient xHE-AAC that offer acceptable quality down to 12 kbps, and the new and excellent AC-4 high-quality audio codec from DOLBY.
Another spin-off from the above Parametric Stereo is Parametric Surround, that is now standardized as MPEG Surround. This gives useful quality 5.1 surround at 64 kbps!
I am proud of the fact that the above technologies are standardized by so many international organizations like ISO/IEC/MPEG/ETSI etc and is applied today in most digital radio, TV, Internet and mobile systems around the world. I am also particularly grateful and proud of my former colleagues who by their skills made this project fly.
Quite funny that my successful SBR idea actually popped-up in my head during an early sunday morning hangover in the bunk of my yacht. The following monday I contacted my patent attorney...
A prestigious milestone in Coding Technologies history!
In November 2007 Dolby Laboratories acquired my dear Coding Technologies and all its 65 employees in Sweden and Germany. In addition to a substantial offer I/we could not refuse, this is the most prestigious milestone in my own and my company's history. I started Coding Technologies in 1997, and this is a once-in-a-lifetime success story!
I am very pleased and satisfied that Coding Technologies, its technology and employees have landed in such safe and established hands as Dolby's. Both companies' devoted experts, technologies and products are complementary and the joined forces will merge into many new and innovative products for the world. (left: Ray Dolby and me in San Francisco 2007)
I was employed by Dolby, from the acquisition in 2007, to my retirement in 2016 as a "Principal Member of the Technical Staff and Senior Advisor Research".

My nomination to the "European Inventor Award - 2017"
I am very pleased and proud to have been selected as one of three finalists in the "Industry category" by the independent international jury, in strong competition with 453 other competent nominees. This nomination is a result of hard work and patents by myself and my colleagues with the above SBR invention.
I did not however take home the Winners Award 2017 at the Venice Italy event. But Jan Boogaart and Oliver Hayden did, having developed an important blood-test to detect malaria. I wish them the best of success with their much needed invention.

After searching around for a rugged, seaworthy ship, I found this classic-style Long-Range Cruiser, a 27 meter (90 ft) and 180 metric tons heavy ocean-going ship in 2004. I could not resist, but made her all mine.
She is a 1994 AquaMarine-90' designed by M. J. Stapleton.
I procured her in Gibraltar and sailed her home to Sweden and Stockholm. This was a beautiful trip, visiting interesting cities and villages along the coastline. It was also incredible to see the dolphins playing in front of the bow, reacting to human calls. A whale was sighted closely when crossing the Bay of Biscay.
However, more engagements, lack of precious time and change of plans, has forced this story to come to an end. I have therefore recently sold this magnificent mega-yacht.
During the years I have been very interested in medicine and researched various fields relating to human biophysical signals. I did in 2000 start up a research and development project in diabetes named DTools, and started a company around this, Diabetes Tools AB in 2005.
The company has a number of specialists working on this project developing new advanced tools for improved simulation, diagnosis and control of diabetes and diabetes related disease. Most hitech R&D projects are initiated by myself and based on my previous research in diabetes physiology. This is a very exiting project with many new and innovative ideas emerging for the benefit of humanity.
Diabetes Tools currently develops smart-phone and Internet based products relating to diabetes treatment using advanced technology and new algorithms. What makes us different from the rest are:
WE CHALLENGE THE DIABETES EPIDEMIC FROM AN ENGINEERING-SCIENTIFIC PERSPECTIVE !
I left Diabetes Tools 2012 due to internal conflicts and lack of skilled personnell. The company was closed down in 2017 due to mismanagement by the steering board and the late CEO and lack of sufficient funding.
Myself together with the acclaimed professors Per-Olof Berggren and Suad Efendic, started up BioCrine AB in 2007. This is a biotech innovations company marketing our innovations, know-how and IP-licenses world-wide in the field of diabetes. This is a spin-off from top-level research performed by the world-class research-team at the Rolf Luft Center of Diabetes Research at the Karolinska Institute, Stockholm.
We are currently performing beta cell transplantations into the interior chamber of the eye. This is a revolutionary method as it is now possible for the first time to follow transplant innervation and transplant vascularization in real-time, in vivo by laser microscopy in the immuno-priviledged eye. This is a new and potential method for diabetes treatment and detailed in vivo studying of beta cell function in the living organism and offers, screening of new and old substances and pharmaceuticals in a new and potent way.

I have always liked hot cars and motorbikes. A couple of years ago I got myself a VW-Trike as I could ride this on my car only drivers licence.
This particular contraption was built from Harley Davidson, Indian, Suzuki and Volkswagen parts. It had a low-compression rebuilt VW-1600 engine with a Holley 500 carburator. Fun to ride with a heck of acceleration! (and 2-wheel wheelies!)
At Coding Technologies I was in the late 90's involved in the Digital Radio Mondiale (DRM) standardization work. I have been demonstrating DRM transmissions using my own portable low-power DRM HF demo-stuff for broadcasters and ham-radio organizations.
(Left) I am performing some local DRM test-transmissions using the professional THALES DRM exiter and some preparation work for the Swedish Radio International DRM test transmissions 2005 from the Hörby station.
(Right) I calculated a realistic coverage map for the log-periodic antenna and transmitter details from the Hörby DRM test transmitter.
At last I got myself a radio amateurs license (SA0AEU)! Strange, it took me nearly a lifetime to get here.
In the picture left, I just passed my examination, and my mentor Conny (SM5DCO) is demonstrating his CW skills.
I am aiming mainly at the HF-band and in particular using digital modulation and communication. I experiment with the simple and very efficient and popular PSK-31 and in addition the amateur radio implementation of DRM, the DRMDV. Parts of my shack shown in the right picture

Early 2005 I was ranked by the Swedish newspapers "Ny Teknik" and "Dagens Industri" as number 8 of Swedens most influential IT-brains!
This is an achivement that I am very flattered and proud of! Nice to be recognised after all years of hard work. Read more: CT press-release (pdf) or this Ny Teknik article (link).
In March 2006, me and my three fellow colleagues at Coding Technologies were awarded the prestigious "Grand Technology Prize" (Stora Teknikpriset) at the annual ceremony at The Royal Swedish Academy of Engineering Sciences. The prize sum is SEK 300.000.- and it was given to me, Per, Kristofer and Fredrik to honor "Innovative excellence in combination with business success". This award is arranged yearly by the Swedish Governmental Agency for Innovation, VINNOVA and technical news magazine Ny Teknik. (This award is sometimes nick-named "The small Nobel Prize"). We are very proud to have recieved this prestigious award in strong competition to other competent nominees. Read more (in Swedish):

I switched from VW Boxer engine to HD V-Twin! Got tired of my VW-Trike (always stuck in city traffic due to its wide-ass), so I got myself a Harley Road King Anniversary-08 with the bigger TwinCam "Fat Head" 96ci engine. A really nice bike for road-race tuning....(see below)
Excellent tools are available today to race-tune your EFI-Harley in off-real-time. Not many riders are aware of the fact that you can actually "dyno-tune" your Harley yourself, on the track, with excellent results!
I have two great tools at hand for this: Harley race-tuner (in data mode at left) and Daytona Twin Scan II tuner (right pic)

An important project that touches my heart so deeply:
I have been participating in a friend's project, the building of an orphanage in south India for destitute little girls (www.enable.dk).
Him, me and some other sponsors have been building and financing a 10 homes village for 70 girls of minor age. Enable is responsible for the little girls in need, their education, their well being and healthcare, and their new and caring home just outside Tranquebar, Tamil Nadu, southeast India. The first 23 girls did move in (2009) to their newbuilt homes and started school.
Little girls are so severely neglected in India. In addition, female infanticide and female foeticide is a severe problem. The female population is declining due to cruel selective elimination!
Read this Indian government report on the Girl Child (pdf).
Me and my girlfriend are also helping a small orphanage outside Pondicherry, Tamil Nadu, southeast India, "S.A.L.T, The Childrens Home", with some of their basic needs. They are extremely poor, and are trying to cope with their hard life and survival on a daily basis.
Before meeting them in 2007, they had no pillows, no blankets and were sleeping on the bare concrete floor. They had no paper to write on, no pens, no schoolbooks and no toys.

We did recently a cruise to Svalbard and Spitsbergen with the arctic-sea and ice-classed cruise ship M/S Fram. Fantastic ship but a somewhat lost but nice Norwegian crew. Great cook and food onboard! We passed the 80 degrees north latitude and that felt really far north and came with stunning views and nature.
It was a freezing but touching experience to watch the remaining glaciers in the so silent and beautiful scenery. However, finding walruses came with a terrible smell from these huge animals. (The walruses are to the right in the right hand picture ;-). We also visited Longyearbyen and met environmental scientists as well as the Greenpeace ship that performed sub-sea pollution research. Very interesting.
Here is a short newspaper article in Swedish from this particular trip.
I am an hopelessly addicted "Time-Nut" and have always been obsessed with accurate time-keeping. I have therefore got myself some very accurate atomic clocks. I am also a modest mechanical chronograph and chronometer collector.
In the picture to the left is my two Rubidium atomic clocks, one EFRATOM (accuracy 1x10-11) and one portable FLUKE PM8565R (accuracy 5x10-11).
In the right picture is my two HP Z3805A Cesium atomic clock receivers (accuracy 1x10-12).
Left is my small watch-repair and time adjust workshop with my professional Weishi and eTIMER time-grapher test instruments for computerized watch timing analysis and adjustment.
The lap-top based eTimer time-grapher is a very advanced and useful test instrument showing:
- Display of the "tic-toc" time-domain envelope
- Graphs of rate, amplitude, deviation and beat error
- Fourier spectrum analysis of cyclical variations
- Allen deviation for assessment of timebase stability
- Escape wheel eccentricity histogram etc
A couple of years ago I built me a professional studio. The audio control-room included a tri-amplified clone of Lipinski L-707 monitor system speakers, with two sub-bass units added. The sound performance and definition was just incredible at 22 Hz - 20 kHz acoustic bandwidth.
I used ProTools with 16-AD in, 128 audio channels in mix position and numerous plug-ins together with the ProTools CI24 fully automated control console. ProTools offers vast possibilities compared to what we had in the old analog days using MCI, Neve or SSL equipment.
The sound studio also contained a number of quality musical instruments, like synths, guitars, bass and Roland electronic V-drums. I also had guitar and bass amps and an EV PA-system for in-house rehersals and the fantastic electronic Yamaha N3 Avant Grand Piano for the critical piano virtuoso.
Some of my productions are with Tino Gonzales (US R&B guitarist) and Susanne Ekberg (opera).
Left picture me and some friends jamming: Chino Mariano (guitar), me (drums), Peter Forbes (bass).
Yes, I am an incurable four-wheel-drive addict, and have owned a number of Jeeps since the mid 1970's.
The latest was a Jeep Wrangler Unlimited Sahara (puh!), a modern tractor with badly designed transmission, bad acceleration and bad road-handling! But...a heck of fun to drive and frequently used to explore rough paths that you just cannot afford to go to with the above bling-bling vehicles.
This one I rebuilt with a Warn winch, fat 33" Cooper offroad tyres, Bushwacker fender flares and specially designed aluminium wheels that has only a small offset as not to impair the scrub-radius steering geometry. The much wider track offers a roll-over angle in excess of 50 degrees, good for stable and safe Jeep mountain climbing!
Me and my girlfriend were off-roading in the Italian West Alp mountains where we were exploring old closed-down military mountain roads that had not been used for nearly 100 years. The narrow tracks are very dangerous and careless drivers has gone over the steep cliff-edges...
It was a fantastic experience dwindling along on top of mountain ridges or going through narrow flooded mountain tunnels. The sights were incredible, something that we will never forget.
I swapped my Jeep for a large SUV, the HUMMER H2. It was like driving around with my living-room or sailing a three ton ship on wheels, looking down at the surrounding traffic.
The HUMMER H2 is a much better design than my previous Jeep, having a Vortec 6 liter V8 of 325 hp and Turbo Hydramatic 4-speed automatic gearbox with overdrive. The transfer-case has a 33:1 crawl ratio in low gear. Electric differential locks in both rear-axle and in the transfer-case. Vented ABS disk-breaks gives good stopping power.
The HUMMER H2 was discontinued in 2009, mainly due to size, high fuel consumption and heavy weight, making it less attractive for the environmentally strict Californian and European markets.
Compared to the Jeep, it was really quiet and relaxing to drive, had great comfort, performed well off-road due to a more advanced transmission and suspension than the Jeep and got more respect due to it's substantially larger size. The wide track of 1.8 m offered a roll-over angle of around 45 degrees. Maximum water fording depth without getting my feet wet was about 50-60 cm. I just loved it!
This picture was taken in the outermost of the Stockholm archipelago (consiting of nearly 30.000 islands and islets), Svenska Hogarna (lighthouse) island, one of the most beautiful and peaceful places in the archipelago. A bit far and hard to reach, but much worth the effort.
This Princess yacht of 45ft was a nice and very well-equipped lady designed for extensive archipelago cruising. She was equipped with a full blown radiator heating system. This extended the cruising season substantially in our nordic climate.
I however sold this motor-yacht in favour for a Princess 20M... :-)
I could not resist (again) and a 70ft Princess 20M became our new yacht. This was a big mama fully equipped for long-range cruising and live-aboard and had all amenities that you could think of. She had three cabins, one ships office, three ensuite toilets with showers and one bathtub, one fully equipped galley with dinner table, full salon with sofas, al-fresco aftdeck, flybridge with table and sofa, wet bar and grill and a rubber dinghy with crane and a large swim platform aft. She carried 5 tons of fuel, had two V12 MAN diesels of 2000 hp and does 32 knots top speed. We sailed her around Sweden and in UK, France, Netherlands, Denmark and Germany.
Left picture is from the beautiful Swedish west-coast.
We were recently in the former east Germany, visiting a Russian T-55 Tank driving school. We both now holds a T-55 driving license each!
The T-55 is the most produced tank ever and is still in use world-wide, runs up to 60 km/h, has a 39 liter(!) V12 diesel at 600hp.
The T-55 is rough and fun to drive (although driver vision is extremely limited by a small narrow periscope).
It was a thrilling experience, in particular when I had the opportunity to crush a car :-)
IEEE Consumer Electronics Award
Me and my former colleagues Martin and Kristofer has been awarded by the Institute of Electrical and Electronic Engineers, the prestigious "IEEE Consumer Electronics Award" at a ceremony 2013 at the Las Vegas Convention Center.
(The IEEE has about 421.000 members in 160 countries world-wide).
This eminent award certainly represents the crowning of my career!
Thanks Martin for your business skills, Per for your filterbank, Kristofer for your technical leadership, and Fredrik for your Fix-Var-envelope and all our clever colleagues for their hard and skilled work refining this invention. You have all erned this eminent award. Finally, thanks to my self for my strength and exceptional persistence fighting all the scepitcal naysayers that said "it would not work"!
I am so proud and humble of being awarded by the IEEE organization together with acclaimed scientists like Irving Reed, Gustave Solomon, Ray Dolby, Karlheinz Brandenburg, Neville Thiele, Richard Small (and in the early days Alexander Graham Bell, Thomas Alva Edison and Guglielmo Marconi) among many others!
Digital Radio Mondiale
I participated early (1997) in the development of the digital radio standard DRM (Digital Radio Mondiale) together with my colleagues and I am keen to see this technology fly as it is more universal and offers more utility than for example DAB.
I have been involved in the "DRM Swedish Field Trials" and have therefore invested in a professional RF-lab for digital radio measurements according to various ETSI and ITU standards. I am now a "Digital Radio Amateur"
The left picture shows my HF-lab with Rohde & Schwarz spectrum and vector analyzers, ABFS Fading Simulator, RF signal and vector generators from R&S and Tek. It also shows my high-power DRM+ amplifier design project. It is a challenging task to build high-power linear PA's with sufficient shoulder distance (low IM-dist), eliminating fragile pre-correction and bulky cavity filters. Low IM-dist is a pre-requisite for handling high crest-factor OFDM signals and achive good SNR and MER at the receiver. I am getting 250 Watts OFDM at 35dB shoulder distance with my home-built power-amp.
To the left, are my two Spark software modulator PC lap-tops from my friend Michael Feilen and two ETTUS hardware exiters for VHF up-conversion.
I also have DRM software demodulators (DRM-radios) running on Android pads.
Me together with some enthusiastic and influential friends has formed a non-profit organization www.digitalradiosweden.com and we have successfully performed DRM+ test transmissions in Stockholm at 500 watts ERP in the FM-band.
I am continuing my diabetes research, due to the fact that I am an insulin-dependent type 2-diabetic and I want to improve on bad traditional treatment regimens.
I have developed a new non-linear insulin-dosing algorithm that gives excellent results. My HbA1c has decreased from 80 mmol/mol to 39 mmol/mol in about 8 months, without a single hypoglycemic episode(!). This result is remarkable and my diabetes professor at the Sophiahemmet clinic is impressed.
I have also built a RF-, audio-, video- noise- ultrasonic- and vibration-lab, where I can perform a number of advanced tests and measurements using state-of-the-art instruments and analysis software, from DC to 7 GHz:
> UHF, VHF, HF, radio and video signal analysis for radio, video links, cameras and video converters.
>Tektronix and Leader video rasterizers and Tektronix video signal generators
> Amplifier, loudspeaker and listening room electroacoustic tests and analysis.
> Advanced hydroacoustic and ultrasonic underwater (sonar) measurements using Bruel & Kjaer reference hydrophones.
> Advanced vibration analysis using Bruel & Kjaer accelerometers, charge amplifiers and calibrators.
> Advanced environmental noise and pass-by noise analysis using the 8-channel noiseLAB Pro software, also including Zwicker loudness, sharpness, roughness and fluctuation strength, and using Bruel & Kjaer and PCB Piezotronics low-noise condenser microphones and calibrators.
No, 2018 has not been my lucky year...
I have been diagnosed with a stage IV unresectable metastasized colorectal cancer (mCRC) that has spread to my abdomen, liver and lungs. The Swedish healthcare system only offers me palliative treatment with chemotherapy, until the end. mCRC is a bad "stealth" cancer disease with the 2nd highest mortality rate of all. As for yourself, beware and go to timely coloscopy check-ups, as this cancer hits you without a warning, without you knowing it.
Being a hi-tech entrepeneur and inventor and a curious scientist, I am deeply shocked by the extreme primitiveness of chemotherapy treatment. Chemotherapy was initially developed from mustard gas, the most deadly chemical weapon deployed in WW1.
The chemo dose titration for my mCRC is performed by using an antique algorithm from DuBois in 1916 based on body area measurements of 9 patients and one dwarf (!). Such body area measurements for chemo dosing has very little correlation with the important chemo concentration acquired in your bloodstream. Therefore treatment based on this old algorithm typically creates patient toxicity, or under-treatment of the patient.
The common treatment strategy used is "fire-and-forget" and after some weeks have passed, "check out what actually happened"?! Not a very scientific approach! The therapeutic window for effective chemo treatment is unfortunately very narrow, therefore better and more precise tools are urgently needed to establish correct treatment doses. A cost-effective dose titration tool is available today "My 5-FU" but due to conservatism it is not yet widely used.
The backbone of modern chemo therapy is an old poison invented in 1957 (5-FU). The second "modern" poison I get in my chemo-cocktail (Irinotecan) was released in 1983. So what the heck is going on in this primitive discipline? Why do not world govenments spend more research resources on cancer as most of us will eventually die having this disease?
