20100303631 | Wind Turbine Rotor Blade Having Segmented Tip - A wind turbine rotor blade is provided. The rotor blade comprises a root portion located in a proximal region of the rotor blade and a tip portion connected to the root portion and located in a distal region of the rotor blade. A spar extends from the root portion to the tip portion. The spar is a unitary member at the root portion and separates into a primary spar and a sub-spar towards the tip region of the rotor blade. Each spar and sub-spar has a respective lifting surface of the rotor blade associated therewith, each lifting surface being distinct from each other lifting surface. | 12-02-2010 |

20090186525 | Shell for Circuit Board Connector - The invention relates to a circuit board connector capable of establishing an electrical connection between circuits on a circuit board and a mating electrical connector at a mating side of said circuit board connector. The circuit board connector includes a connector housing accommodating a plurality of terminals for establishing said electrical connection and an electrically conductive shell at least partially enclosing said connector housing. The shell includes a top wall and a rear wall, wherein said rear wall is connected to said top wall and is arranged opposite to said mating side. The shell further has a first and second extension connected to opposite sides of said rear wall and bent with respect to said rear wall to extend towards said mating side. First and second mounting posts are connected, respectively, to said first and second extension and third and fourth mounting posts are connected to said rear wall, wherein said mounting posts are arranged for mounting said shell on said circuit board. | 07-23-2009 |

20080240443 | METHOD AND APPARATUS FOR SECURELY PROCESSING SECRET DATA - Using the same secret key for different secret operations in the frame of public key cryptosystems raises security problems because attackers can gain statistical information about the secret key. Indeed, when randomization techniques are used, the same secret key is randomized differently for every new operation, and since information leakage sums up, eventually, the attacker is able to recover the secret key. | 10-02-2008 |
20090187766 | System and Method for Digital Signatures and Authentication - A system and method for authentication and digital signatures on memory-only supports, comprising a read-once memory unit storing secret arrays, whose contents are destroyed upon reading, a standard memory unit storing encrypted arrays, tree data authenticating the encrypted arrays to one single public key, and a certificate of the public key issued by a certificate authority. The memory support sends its public key and certificate to a verifier, receives a challenge which is signed by elements from secret arrays in the read-once memory. The verifier system checks the authenticity of the data revealed from the read-once memory by encrypting it and comparing the result to one of the encrypted arrays, and verifies that the encrypted array authenticates to the public key using tree data. Finally, the verifier checks the authenticity of the public key using the certificate. | 07-23-2009 |
20090245507 | DATA PROCESSING SYSTEM AND DATA PROCESSING METHOD - A technique which contributes to materialization of efficient encryption even with devices such as smartcards restricted in memory resource is provided. The system for generating cryptographic keys includes: | 10-01-2009 |

20110161390 | MODULAR MULTIPLICATION PROCESSING APPARATUS - A modular multiplication processing apparatus is provided that can process modular multiplication of data exceeding a bit length which a coprocessor can readily process, by using the coprocessor based upon Montgomery multiplication In the modular multiplication processing apparatus, data to be subjected to modular multiplication is decomposed, and the decomposed data elements are transformed into a form suitable for Montgomery multiplication, respectively. Further, after respective data elements are transformed to have sizes that can be inputted into a coprocessor, Montgomery multiplication is repeatedly performed in the coprocessor. A remainder of Montgomery multiplication of an original bit length is restored from the obtained remainder. | 06-30-2011 |

20130182839 | SEMICONDUCTOR DEVICE AND IC CARD - In power residue calculation in a primality determination, in addition to the conventional randomization of an exponent, a modulus is also randomized. A random number generated by a random number generator is set to a randomizing number, and is input to a modulus generator and an exponent generator. The modulus generator and the exponent generator randomize a prime number candidate P using the randomizing number to generate a randomized modulus R | 07-18-2013 |

20090130254 | Process for Removal of Toxic or Undersirable Polyhalogenated Compounds in Beverages, Especially in Wine - The invention relates to a method for eliminating toxic or undesirable polyhalogenated compounds from drinks. Said method is characterised in that it comprises a step for bringing the drink into contact with an adsorbent consisting of a synthetic polymer material obtained from a mixture of aliphatic and non-aliphatic monomers. The aim of the invention is especially to eliminate halophenols and haloanisols in wine, with short periods of treatment. | 05-21-2009 |
