Abstract: Methods and systems for determining motion vectors in a motion estimation process of a video encoder are provided. Embodiments of the present invention provide a solution for the problem of unnecessary cost function evaluations, found when combining the successive elimination method with a predetermined list of candidate motion vectors search ordering. In order to solve this problem, embodiments of the present invention provide an adaptive scan ordering of block matching candidates within a search area. Advantageously, embodiments of the present invention will only evaluate necessary cost functions, without impacting rate-distortion.

Abstract: A draining system for water which may collect between the upper and lower membranes of flat, horizontal or slightly sloped insulated roofs upon perforation of the upper membrane. The insulating panels located between the two membranes are provided at both their upper and lower faces with a network of intersecting grooves, and these networks communicate with each other through passages made through the insulating panels or constituted at the panel joints. A lower drain member is sealed to and opens above the lower membrane to drain any water having seeped under the broken or perforated upper membrane, so as to prevent deterioration of the insulating panels and water accumulation which may provoke considerable roof overload problems. In certain roof constructions, the network of upper grooves is not necessary.

Abstract: The invention is concerned with a dismantable joint arrangement comprising three pairs of spaced-apart parallel members, which are arranged relative to one another such that the members of each pair cross the members of the other pairs in abutting engagement therewith and any one pair of members has a respective second pair of members interposed therebetween and a respective third pair of members adjoined thereto and interposed between the members of the respective second pair. At least two dowell-type coupling elements are associated with each pair for positioning the members thereof against those interposed therebetween. The coupling elements are removably inserted in corresponding holes formed at the crossings of the members and are slidably frictionally engaged in the holes so as to be retained therein by frictional force while being slidably removable by the application of manual force.
