Rotary Cutting Tool and Reversible Cutting Insert Therefor

In a rotary cutting tool used for milling operations, a reversible indexable cutting insert is removably secured in a cutting body. The cutting insert has two opposing end surfaces interconnected by a continuous peripheral surface, including three side surfaces alternating with three corner surfaces. The side and corner surfaces intersect with both end surfaces at side and corner edges, respectively, with each side edge having a major cutting edge, and each corner edge having a corner and minor cutting edge. Each major and minor cutting edge slopes away from first and second end points, respectively, of its mutually associated corner cutting edge, towards a median plane. A first imaginary straight line extending perpendicular to the median plane and intersecting any one of the corner cutting edges at any point along its length except the second end point, passes through the median plane inside an insert boundary line.

Method and system for information association

Method and system for information association based on an absolute position coding pattern comprising dots or markings which codes coordinates for a position on an imaginary surface. The imaginary surface comprises several regions which are divided in areas, each defined by said coordinates. Handwritten information is digitized by a handheld device which is moved over a surface provided with said pattern and acts like a pen to make notes on the surface. At the same time, the pattern is sensed and coordinates for the pen is calculated regularly. By passing the handheld device over the borderline between areas having different coordinates, a hyperline is generated having a discontinuity. Such a hyperline is easily recognized by the computer system and is used for connecting information at different areas, giving information some properties, like color, or performing an action on the information, such as encryption, or transferring the information to a recipient.
