Where did Swedens Top 100 innovations originate?

This study has investigated how 100 of the most important Swedish innovations have emerged.The results indicate that 47 percent of the top one hundred innovations were created by inventors as employees of companies, while individual inventors and entrepreneurs have contributed 33 percent and university finally accounts for the remaining 20 percent. Companies and individuals often have a combination of technical expertise and market knowledge that allows radical innovations to emerge. Companies often may have a cash flow that sometimes can be used for funding extensive development.
An important conclusion is that the independent inventors' role has become more prominent in recent decades. Of the twenty major innovations during the period 1955-1979 25 percent of those emerged from independent inventors. Of the 20 innovations between years 1981 to 2006 no less than 45 percent came from this category. The independent inventors in other words have become increasingly important in Sweden.
Some important innovations from independent innovators:
The Respirator, Sparkling mineral water, The Screw propeller, The telephone handset,
