Patent GB-2266023-A (GB)
Title: Motion dependent video signal processing
Inventor: DAVID MORGAN WILLIAM AMOS
IPC: G06T7/20
Filed: 1992-03-31
Abstract: A method of processing a digital video signal to derive motion vectors representing motion between successive fields or frames of the video signal comprises comparing the contents of blocks of pixels in a first field or frame N of the video signal with the contents of a plurality of blocks of pixels in a following field or frame N+1, and producing for each said block in the first field or frame N a correlation surface representing the difference between the contents so compared in the two fields or frames N, N+1. A grown correlation surface is produced for each said block in the first field or frame N by weighting the correlation surfaces for that block and a plurality of other blocks in an area around that block so as to accentuate features of the correlation surface for that block relative to those for the said other blocks, and summing the weighted correlation surfaces. From each grown correlation surface a motion vector is derived representing the motion of the content of the corresponding block between the two frames N, N+1 in dependence upon a minimum difference value represented by the grown correlation surface. <IMAGE>

Title: Method of and apparatus for simultaneously producing two continuous tobacco streams
Inventor: HEITMANN UWE
IPC: A24C5/18
Filed: 1992-04-29
Abstract: Two tobacco streams are made simultaneously by feeding a main flow of tobacco particles upwardly through a suction duct which terminates beneath two parallel foraminous belt conveyors. The sidewalls of the duct have alternating wedge-like ramps which divide the ascending main flow into plural first and second flows in such a way that the first flows advance from one of the sidewalls toward the other sidewall and the second flows advance from the other sidewall toward the one sidewall. In addition, the sidewalls and their ramps define several passageways for unimpeded ascent of numerous relatively small third flows of tobacco particles directly against the convex underside of a partition which is located in the duct between the two conveyors. The partition breaks up each third flow into two equal partial flows and causes each partial flow to rise toward a different foraminous conveyor. This ensures the division of the main flow into two equal streams without any classification and/or other undesirable influencing of tobacco particles. <IMAGE>

Title: A hierarchical synchronization method and a telecommunications system employing message-based synchronisation
Inventor: KAINULAINEN JUKKA
IPC: H04J3/06
Filed: 1993-11-08
Abstract: The invention relates to a hierarchical synchronization method for a telecommunications system employing message-based synchronization and to a telecommunications system employing message-based synchronization and comprising a plurality of nodes (1...6) interconnected by transmission lines. In the method, the nodes interchange signals containing synchronization messages with information on the priority of the respective signal in the internal synchronization hierarchy of the system. In order to speed up resynchronization in failure situations, when the node loses the selected timing source, it attempts to select as a new synchronization source a neighbouring node transmitting a synchronization signature which is on the same level in the synchronization hierarchy of the system as the synchronization signature of the lost timing source and which is closer to the master node of the system than the node itself, whereby when such a node is found, the node selects it as its new synchronization source, or if such a node is not found, the node starts a procedure known per se for finding a new connection to the master node. <IMAGE>
Patent GB-2291266-A (GB)
Title: Submicroscopic pattern formation on semiconductors
Inventor: KIM HYEONG SOO
IPC: G03F7/20
Filed: 1995-07-12
Abstract: A photoresist film (3) is coated onto a lower layer (2) to be patterned. The photoresist film (3) is exposed a first time to light (6) by way of a mask (5). The mask (5) is shifted relative to the layer (2) by a distance W1 and then the photoresist film is exposed through the mask (5) a second time. During each light exposure, the energy of the light is lower than the threshold energy for the thickness of the photoresist film. Thereafter, the exposed photoresist film is developed to completely remove regions in which primarily exposed regions of width W1 (4) overlap with secondarily exposed regions (4'). Regions which have only been subjected to one exposure to light are only partially removed and form photoresist film patterns (3'), each having four side walls. An insulating layer (8) is deposited over the resulting structure and is subjected to an anisotropic etch to form insulating layer spacers (8') at the side walls of the photoresist film patterns (3'). The photoresist film patterns (3') and the lower layer (2) are then etched with the insulating layer spacers (8') serving as a mask, to form lower layer patterns (2') having a submicroscopic width and a submicroscopic spacing. More submicroscopic patterns can be formed by this method than is possible with conventional photolithography. <IMAGE>
