ALBIHNS’ Innovation Award is handed out annually for an innovation that has been developed by a person from Skåne or a company operating in the province, which is considered by the jury to display a high level of innovation and considerable market potential. With this award, ALBIHNS MALMÖ AB hopes to stimulate new thinking and inspire innovations. It is also a way of highlighting the creative people behind the ideas that make life better for all of us.
The motivation of the jury:
"Lyyn AB has developed a well-functioning technique for improving visibility. The system can be used for digital pictures as well as for video and ordinary cameras. This technique is especially useful in traffic and medical contexts."

The new weapon in the fight against art fraud uses digital analysis to capture details of an artist’s characteristic strokes of brush, pen and pencil, which are then combined to produce an “electronic signature” of his style. This digital blueprint can determine beyond reasonable doubt whether a disputed work was indeed created by the hand of an Old Master as claimed, or whether it is a sophisticated forgery. It also promises to resolve longrunning arguments about whether many paintings were the work of great figures such as Leonardo da Vinci or Raphael alone, or whether certain sections were completed by assistants. The new software has been designed by a team at Dartmouth College in New Hampshire, led by Hany Farid, and is suitable for paintings, prints and drawings. |

The muzzle blast and supersonic bullet from firing a Magnum .44 caliber gun is "frozen" in time by a microsecond exposure by the Penn State Gas Dynamics Lab utilizing a technology called Schlieren photography. Schlieren photography allows the visualization of density changes, and therefore shock waves, in fluid flow. Schlieren techniques have been used for decades in laboratory wind tunnels to visualize supersonic flow about model aircraft. |

A simple schlieren system can be built with a single mirror with a long focal length; telescope mirrors can be used for this purpose. The camera and light source are placed close together on either side of the focus, aimed at the mirror. Any straight-filament light bulb will serve; those used in a refrigerator are fine. The target is then placed between the camera and the mirror, typically as close to the mirror as possible to reduce the effective angle between the light source and camera. Light from the filament travels to the mirror where it is collimated (light rays are parallel and thus has a plane wavefront), then across the target and to the camera.
With high-speed cameras, high-magnification lenses and very bright lights, schlieren photography can make the details of airflow visible. This makes it invaluable for studying streamlining and aerodynamics.
