Patent number: 9250996Abstract: In a multicore type error correction processing system which can simultaneously cope with a plurality of error correction methods and a plurality of code lengths, an interconnect part 11 has a barrel shifter which extends across a plurality of error correction processing parts 12a-12c. An error correction process can be selectively performed by collectively using a group of the plurality of the error correction processing parts 12a-12c or by individually using each of individual error correction processing parts 12a-12c in response to interconnection configuration information. With this structure, the plurality of the error correction processing parts 12a-12c are collectively used if computation resources are insufficient and an idling error correction processing part is assigned to another error correction process if computation resources are excessive.Type: GrantFiled: October 4, 2011Date of Patent: February 2, 2016Assignees: NEC CORPORATION, TECHNISCHE UNIVERSITAT DRESDENInventors: Tomoyoshi Kobori, Steffen Kunze, Emil Matus, Gerhard Fettweis

Patent number: 8734704Abstract: The present invention relates to a method of fabricating a mold core (5) for making hollow parts (11) based on a composite material including fibers, fabrics, or textiles together with a resin, the method consisting in mixing a filler material (1) and a binder material (2) in order to obtain a uniform mixture of materials, and in solidifying, compacting, and shaping the resulting mixture in order to constitute said core, the method being characterized in that it further consists in introducing into the mixture at least one complementary material (3) that is expandable under the effect of heat or by applying another physical or chemical principle, and in mixing said materials (1, 2, 3) in order to obtain a uniform distribution of the complementary material (3) in the mixture.Type: GrantFiled: December 15, 2010Date of Patent: May 27, 2014Assignee: Airbus Helicopters Deutschland GmbHInventor: Steffen Kunze

Patent number: 8641952Abstract: A method of fabricating components (23) based on fiber-reinforced plastics material, in particular with the help of a wrapped mold core (10), includes the following steps: a) fabricating the mold core (10); b) wrapping the mold core (10) with a wrapper (14) that withstands resin; c) applying fiber semi-finished products (16) and introducing resin to create the plastics component (23); and d) hardening the plastics component (23) under the effect of temperature; which method is improved by the fact that, under all circumstances, and during hardening in step d), substantial pressure equilibrium is established across the fiber semi-finished product (16, 20) between ambient pressure (pu) and the pressure (pk) inside the core. A device is also described.Type: GrantFiled: July 20, 2009Date of Patent: February 4, 2014Assignee: Eurocopter Deutschland GmbHInventors: Tom Kretschmer, Steffen Kunze, Christian Wellhausen
