Granted: 2003-06-17
Abstract: A plurality of round processing parts (38) are provided each of which contains a nonlinear function part (304), and each nonlinear function part (304) comprises: a first key-dependent linear transformation part (341) which performs a linear transformation based on a subkey; a splitting part (342) which splits the output from the first key-dependent linear transformation part into n pieces of subdata; a first nonlinear transformation part (343) which nonlinearly transforms those pieces of subdata, respectively; a second key-dependent linear transformation part (344) which linearly transforms those nonlinearly transformed outputs based on a subkey and outputs n pieces of transformed subdata; a second nonlinear transformation part (345) which nonlinearly transforms those transformed subdata; and a combining part (346) which combines the nonlinearly transformed outputs. An n x n matrix, which represents the linear transformation in the second key-dependent linear transformation part (344), is formed by n vectors whose Hamming weights are equal to or larger than T-1 for a security threshold T, thereby increasing the invulnerability against differential cryptanalysis and linear cryptanalysis.

Title: Method and apparatus for packing and decoding audio and other data
Inventor: DUNCAN DAVID
IPC: H04H20/88
Filed: 2000-12-20
Granted: 2006-04-18
Abstract: A method and apparatus for compressing digital data, particularly audio and other data, in a way that the packing method used can be automatically detected and decoded at the receiving station. The audio signal is divided into compression packets consisting of four word pairs of left and right words. The first word pair in each compression packet is tagged with an identifier to indicate the start of a new compression packet, and is provided with configuration information which, over an entire compression block of 48 compression packets, constructs a 48-bit word specifying the manner in which the compressed audio and other data is packed. The method and apparatus of the invention is able to compress digital audio and other data to accommodate 16-, 20- and 24-bit resolutions and transmit up to eight channels of audio information in a variety of formats, and makes more efficient use of available bandwidth in the 16-, 20- or 24-bit output by allowing other information to be embedded into the least significant bits of the remaining available compression packet space which would otherwise be dropped.

Abstract: L'invention concerne un procédé amélioré de préparation de bâtonnets de pommes de terre congelés et de produits analogues, lequel consiste à blanchir ces bâtonnets, à les frire à demi dans l'huile sous vide et, enfin, à les congeler. Dans un autre mode de réalisation, lesdits bâtonnets sont blanchis, frits dans l'huile sous pression atmosphérique, refroidis à l'air, frits à demi dans l'huile sous vide et, enfin, congelés. Le procédé permet de produire une pomme de terre congelée qui peut être reconstituée dans un délai relativement court et, de plus, présenter une couleur brillante, un arôme de pomme de terre renforcé, une texture superficielle plus tendre et d'autres caractéristiques avantageuses. Ce procédé autorise aussi l'utilisation d'huiles aromatisées et d'huiles plus légères. Selon un autre mode de réalisation de la présente invention, des pommes de terre congelées préparées de façon classique sont frites dans l'huile sous vide et recongelées. Le délai de reconstitution de ce produit recongelé à faire refrire rapidement est beaucoup plus court que celui de la plupart des pommes de terre congelées classiques.

Filed: 1999-12-31
Granted: 2009-09-22
Abstract: A device and a method are proposed in which the sender divides an amount of data to be sent into one or more data units and the receiver acknowledges the correct receipt of data units by returning acknowledgment data units to said sender. The data units are sent by said sender in accordance with a flow control procedure that involves one or more adaptive parameters. After a given data unit is sent, the sender performs a data loss detection routine, and if a triggering event occurs, a corresponding response procedure is conducted, where this response procedure comprises at least two different modes for adapting said one or more adaptive parameters. Preferably, there is a first and a second mode, where the first mode is associated with the actual loss of a data unit, so that this first mode comprises the conventional data loss procedures, and where the second mode is associated with the recognition that an excessive delay has taken place and not a loss of a unit.

Abstract: The invention relates to a method and a device for producing a circumferentially closed hollow profile, a hollow-profile blank being expanded by means of fluidic internal high pressure in an internal high-pressure forming tool, after which said hollow-profile blank assumes the final shape of the hollow profile. In order to make it possible in a simple way to have a production of a hollow profile in which process reliability is ensured to a sufficient extent even in the case of high expansions of the hollow profile (higher than or equal to the breaking elongation of the material), it is proposed that, during expansion, the hollow-profile blank be supported, on at least one partial circumferential region, by means of at least one diaphragm fastened to the inside, facing the blank, of the tool and capable of being acted upon by a controllable pressure acting from outside, said diaphragm shifting back elastically as expansion progresses, with the supporting pressure acting on the diaphragm being reduced at the same time.

Abstract: A molten-bath based direct smelting process and apparatus for producing metals from a ferrous material is disclosed.  The process includes injecting feed materials being solid material and carner gas into a molten bath at a velocity of at least 40m/s through at least one downwardly extending solids injection lance having a delivery tube of internal diameter of 40-200mm that is located so that a central axis of an outlet end of the lance is at an angle of 20 to 90 degrees to a honzontal axis. The feed materials injection generates a superficial gas flow of at least 0.04 Nm3/s/m2 within the molten bath at least in part by reactions of injected material in the bath. The gas flow causes molten material to be projected upwardly as splashes, droplets and streams and form an expanded molten bath zone, with the gas flow and the upwardly projected molten material causing substantial movement of material within the molten bath and strong mixing of the molten bath. The feed materials are selected so that, in an overall sense, the reactions of the feed materials in the molten bath are endothermic. The process also includes injecting an oxygen-containing gas into an upper region of the vessel via at least one oxygen gas injection lance and post-combusting combustible gases released from the molten bath.
