Publication number: 20060251330Abstract: The invention concerns a method for compressing a digitally coded video frame sequence. In the method, a given frame is divided into blocks, and the information content of selected blocks is modified, relying on information contained in a neighbouring block or blocks (prediction), and the blocks are converted from spatial representation into frequency representation. The information content of the transformed blocks is encoded by arithmetic coding. The efficiency of the coding is improved by various methods, such as dynamically partitioning the blocks into sub-blocks, or performing a compressibility analysis is the blocks before carrying out further transformations. The entropy coding uses a neural network to determine the parameters of the arithmetic coding. The frames are dynamically re-scaled, depending on available bandwidth and quality of the coded image.Type: ApplicationFiled: May 20, 2004Publication date: November 9, 2006Inventors: Peter Toth, József Károly

Patent number: 5322016Abstract: A weapons system with at least one fire control device and a launcher uses a remotely fragmentable projectile for defense against a missile or other movable target. Although the probability of a hit is increased with the use of a remotely fragmentable projectile, the system of the invention increases the success of the defense, which is nevertheless questionable because of the low density of the projectile fragments. The method utilizes a projectile, the fragments of which are concentrated in a ring, which spreads out in the shape of a conical envelope. The projectile is individualized at launch. Tracking of the target continues during the flight of the projectile, because of which the expected location at the pre-calculated time of impact becomes continuously better known. The fragmentation command is transmitted to the projectile as late as possible. It is always possible with a high degree of probability to score a hit.Type: GrantFiled: December 2, 1992Date of Patent: June 21, 1994Assignee: Oerlikon-Contraves AGInventor: Peter Toth

Patent number: 5208418Abstract: The method and apparatus for determining and correcting alignment errors between fire control devices and weapon systems are distinguished by the following features. Target measuring sensors are mounted on guns which are mounted on servo-controlled mounts, and the sensor line of sight of each target measuring sensor is aligned with the line of sight of the gun. The guns containing the target measuring sensors are aligned to a common measuring target using a target tracking device. A deviation between the measured position of the common measuring target and the position of the line of sight of the target measuring sensor is detected in the target measuring sensor of the gun which is controlled by the target tracking device. This deviation is evaluated and processed to determine an alignment error vector taken into account during control of the gun. Control signals used during a firing operation are corrected on the basis of the alignment error vector.Type: GrantFiled: December 9, 1988Date of Patent: May 4, 1993Assignee: Oerlikon-Contraves AGInventors: Peter Toth, Peter Schueepp
