ALEXANDRIA, Va., July 30 -- United States Patent no. 12,372,331, issued on July 29, was assigned to Inno Invent APS (Vipperod, Denmark).

"Device for achieving frictionless linear movement in a single direction and stiffness in all other directions" was invented by Glenn Arthur Jorgensen (Vipperod, Denmark).

According to the abstract* released by the U.S. Patent & Trademark Office: "A device for achieving linear movement in a single direction and stiffness in all other directions. As an example, a recoil causes strong forces in a linear movement, but any ridges will produce errors as two units each try to return to its original position. The device is a damper. The linear displacement by a recoil is mitigated using two set of blades, one a...
