A set of mini Mecanum Wheels and mini DC motors.

Swedish Inventions

The following are among some significant inventions created by Swedes:
•Rune Elmqvist developed a small battery-driven pacemaker in 1958. The first operation when a pacemaker was placed into the heart region was surgically performed at the end of 1958. Although the device only lasted for a few hours and there was a need for further adjustments, the patient (Arne Larsson) survived these tests and lived for decades, right up to 2001. This patient lived to the age of 86 and outlived the inventor and surgeon.
•Astra Zeneca developed Losec. Losec is recognised as a common drug medicine for ulcers and was the world's best-selling drug in the 1990s.

•Bengt Ilon invented the Mecanum wheel. This is a wheel which is capable of moving in any direction.
•Nils Bohlin’s created the three-point seat belt. Since 1959 this invention is regarded as having saved one life every six minutes. Consequently this Swedish invention is considered to be one of the most important safety innovations of all time.
•Håkan Lans developed the satellite-guided GPS system (Global Positioning System). It has been upgraded and improved into its modern form. The GPS is now able to ensure motorists reach their destinations on time and without hassle, by being guided with electronic positioning and directions to one’s destination.
•Erik Wallenberg had the idea and with the assistance of his dedicated team, the Tetra-Pak was invented. This is regarded as a solution to packaging, storing and distributing liquids such as juice and dairy items. Since its formation in 1951 these cardboard package holders have been utilized globally, to store and maintain the freshness of liquid foods in fridges.

•Nils Alwall was a pioneer and leader in haemodialysis and is acknowledged with the invention of one of the first practical dialysis machines. The technique of ultrafiltration and the introduction of the principle of hemofiltration was created by Nils, who is referred to as the "father of extracorporeal blood treatment."
•Lars Magnus Ericsson developed the telephone handset in 1885, among his many improvements and upgrades to contemporary telephones.
•Willgodt Theophil Odhner invented the Odhner arithmometer, which is the mechanical calculator.
•Anders Celsius has become most famous for inventing the 100-point thermometer scale, widely used across the world. Consequently we now measure a scale of temperature in Celsius degrees, named in honour of the inventor
•Sven Torbjörn Lagervall discovered ferroelectric liquid crystals in 1979. The technology was developed and finally used in 1994 for major production of the flat scree monitor.

•Hellmuth Hertz began leading work in 1950 with ultrasound for medical diagnosis. Together with cardiologist Inge Edler, the technique with ultrasound was developed for the analysis of heart diseases.
•Gustaf Erik Pasch, in 1844 patented the safety match. Gustav utilized non-poisonous red phosphorus on matches, instead of the usual poisonous yellow phosphorus that was the norm during those times to ignite a spark.

•Gideon Sundbäck in 1913 invented the zipper, which is based on interlocking teeth. The original name of this invention was ‘hookless fastener’. However later it was redesigned to be more reliable and became known as the zipper or zip. The zip is ubiquitous as it is a device for binding the edges of an opening of fabric or other flexible material, such as a jacket, bag, tent or pair of jeans.
