Title: A method relating to the handling of transactions in databases
Inventor: RONSTROM MIKAEL
IPC: G06F17/30
Filed: 1999-07-22
Abstract: The present invention relates to a method of handling the risk of a deadlock between simultaneous transactions (T1, T2) in a database (1). The method is based on allocating to respective objects (01, 02) in the database (1) a lockout queue (L1, L2) in which transactions (T1, T2, T3, ..., T8) that request access to an object (01, 02) are placed to await the access to said object of a preceding transaction. The handling procedure comprises going through, or perusing, the lockout queues (L1) belonging to different objects (01) to detect so-called locking transactions (T1) that can cause a deadlock and, subsequent to detection, comparing said locking transaction with other transactions (T2, T6, T1, T7, T8) in other lockout queues (L2) therewith enabling the risk of deadlock between a first and a second transaction (T1, T2) that have both requested access to the same first and second object (01, 02) to be detected. Combinations of transactions that are ongoing or active in the database and that, according to said comparison, can cause a deadlock are divided into locking and non-locking combinations respectively. Solely the detection of a locking combination will cause further action to be taken.

Abstract: The input device for control signals for controlling the movement of an object represented on a display device is fitted with a housing (24) and three control signal generating devices (38, 40, 42) to generate first control signals. The input device also comprises three actuating organs (32, 34, 36) disposed orthogonally in relation to each other, wherein each organ is mounted in such a way that it may be displaced linearly along a spatial axis (x, y, z) on or in the housing (24) and protrudes outwards above the housing (24) in two opposite areas of said housing (24). Each actuating organ (32, 34, 36) interacts with one of the control signal generating devices (38, 40, 42), wherein the control signal generating devices (38, 40, 42) generate the first control signals depending on the displacement position of the actuating organs (32, 34, 35). Spatial orientation of the housing (24) is recognized by a position recognition sensor (46) and representation on the display is adjusted in correspondence with the position and location of the housing (24).

Abstract: Procédé servant à améliorer la qualité d'une image comprimée. Cette amélioration consiste en l'apport de certaines composantes d'erreur produisant une image moins <= propre >=, ce qui est désigné également en tant qu'aspect du film. Ce système et ce procédé effectuent une transformation de sous-bande sur une ou plusieurs images, ce qui consiste à diviser l'image en une ou plusieurs composantes haute fréquence, basse fréquence ou fréquence de courant continu. En réaction à une composante contenant des fréquences de courant continu, les données de cette composante sont linéarisées. Ces dernières sont ensuite déquantifiées. La linéarisation des données consiste, de préférence, à ajouter une fonction présentant une répartition de probabilités et d'intensités similaires à l'erreur de quantification des données. De plus, la linéarisation des données peut également consister à mettre en application une fonction reproductible avec exactitude et génère des valeurs aléatoires imitant étroitement la répartition d'erreurs de quantification.

Title: Method of forming a powder compact
Inventor: TAKEMOTO SHIGEHIDE
IPC: B22F3/02
Filed: 2000-12-13
Abstract: This invention provides a method of forming a powder compact which can produce a high density compact under a high pressure and at the same time can reduce pressure for ejecting the compact from a die.      This method comprises the application step of applying a higher fatty acid lubricant to an inner surface of a heated die, and the compaction step of filling metal powder into the die and compacting the metal powder under such a pressure as to force the higher fatty acid lubricant to be chemically bonded with the metal powder and form a metallic soap coating. Since the metallic soap coating is formed between the die and a compact, friction force between the die and the compact is decreased and ejecting pressure can be remarkably decreased despite of compaction with high pressure.      Besides, a high density compact can be obtained owing to the compaction with high pressure.

Title: Enhancements for seams in on-machine-seamable papermaker's fabrics
Inventor: KORNETT GLENN J
IPC: D03D11/00
Filed: 2002-02-11
Abstract: An on-machine-seamable papermaker's fabric, which may be produced by modified endless weaving, includes machine-direction (MD) and cross-machine-direction (CD) yarns.      When so produced, the MD yarns weave continuously back and forth between the two widthwise edges of the fabric, each time forming a seaming loop at one of the two widthwise edges. Interwoven with at least one of the two sides, top and bottom, of the seaming loops at one or both widthwise edges are at least two additional CD yarns. The additional CD yarns interweave with the top and/or bottom of the seaming loops in a leno weave; which keeps the seaming loops in a common position vertically relative to the plane of the papermakers fabric, locks the seaming loops into a desired position and orientation with their planes perpendicular to that of the papermaker's fabric.

Abstract: A method for inserting a digital signature into digital data is provided. In reference to the figure, the digital data (200) has bits and the method includes the steps of: assigning predetermined bits of the digital data for receiving the digital signature (202); signing the digital data excluding the predetermined bits (210 and 220) resulting in the digital signature; and inserting the digital signature into the predetermined bits of the digital data (226) for subsequent authentication of the digital data. Also provided is a method for authenticating digital data having the embedded digital signature in the predetermined bits of the digital data including the steps of:  extracting the digital signature from the predetermined bits; decrypting the digital signature from the digital data resulting in a first hash; applying a known one-way hash function used by an encoder of the digital data to the digital data excluding the predetermined bits resulting in a second hash; and comparing the first hash to the second hash wherein if the first hash matches the second hash the digital data is authentic. In a preferred version of the methods of the present invention, the method further includes the step of inserting associated data into the digital data (208) prior to the signing step such that the digital signature authenticates both the associated data as well as the digital data. Preferably, the associated data is inserted into the bits of the digital data excluding the predetermined bits.
