20100102127 | Device for Protecting an Electronic Component - An electronic system comprising a printed circuit having first and second opposite surfaces, an electronic component attached to the second surface and a first device of protection against access attempts on the first surface side. The system comprises a second protection device at least partially covering, on the second surface side, the electronic component, and comprising at least one tab. The printed circuit comprises at least one through opening, the tab extending in the opening and being attached to the printed circuit. The tab comprises at least one conductive portion electrically contacting at least one first conductive track of the first surface. | 04-29-2010 |
20110100788 | PROTECTION DEVICE FOR ELECTRONIC SYSTEM - An electronic system including an electronic circuit, an actuation device, a spacer and a protection device. The electronic circuit has a surface on which at least two first conductive tracks are arranged. The actuation device includes at least one first bearing element. The spacer is interposed between the electronic circuit and the actuation device and includes at least one opening at least partially receiving the bearing element. The protection device is interposed between the electronic circuit and the spacer and includes at least one second conductive track having ends respectively connected to first conductive portions of first deformable regions of the protection device. Each first portion is capable of contacting one of the first conductive tracks of the electronic circuit to electrically supply the second track under the effect of a deformation of first regions. | 05-05-2011 |

20100169671 | CRYPTOPROCESSOR WITH IMPROVED DATA PROTECTION - The invention relates to an electronic circuit comprising: a first random-access data storage element, a processing module designed to delete the first storage element, and an access terminal which is connected to the processing module and receives a first power signal supplied by a first power source external to the electronic circuit. The circuit also includes a second random-access storage element in which a key is stored, said key being used to encrypt the data and a second power source which is built into the electronic circuit and supplies a second power signal to the processing module. The processing module is designed to detect an unauthorized access attempt by comparing the first and second power signals and to delete the key when the processing module is powered by the second power source. | 07-01-2010 |
20100180122 | Method and Device for Detecting an Attempt to Substitute an Original Casing Portion of an Electronic System with a Replacement Casing Portion - The invention relates to an electronic system comprising a casing consisting of at least first and second casing portions and containing a device for detecting the substitution of the first casing portion. The device comprises a first integrated circuit intended to be fixed to the first casing portion and a second integrated circuit intended to be fixed to the second casing portion. The second circuit is adapted to transmit to the first integrated circuit successive random or pseudo-random digital signals (R). The first integrated circuit is adapted to return to the second integrated circuit, for each digital signal, the first encrypted signature (S) from said digital signal. The second integrated circuit is adapted to determine a second encrypted signature (S′) from said digital signal and to detect a substitution of the first casing portion if the first and second encrypted signatures are different. | 07-15-2010 |

20130326985 | AQUEOUS GYPSUM PLASTER-CEMENT COMPOSITION AND ITS USE - An aqueous gypsum plaster-cement composition comprises a hydraulic binder consisting of calcined gypsum and hydraulic cement in a weight ratio of from about 4:1 to about 2:1, an aggregate which comprises sand, a foam, a perlite, rice hulls or a mixture thereof, a superplasticizer comprising an air entraining agent, a retarder, and water in an amount of from about 0.4 to about 0.75 parts by weight per part of binder, with the proviso that the gypsum plaster-cement composition contains essentially neither a pozzolana nor lime. The use thereof, a method of constructing buildings using this composition and the buildings obtainable in this way are also described. | 12-12-2013 |

20100161619 | Method and Apparatus for Generating Recommendations From Descriptive Information - Meaningful words or phrases may be extracted from the information and used as tags. Weights may be determined for the tags, and tag clouds may be generated for the items. The tag clouds may be stored to a data store. Information specifying a tag cloud may be received. Recommended items for which the tag clouds most closely match the specified tag cloud may be identified. Standard vector space distance calculations, for example the cosine distance between the tag clouds, may be used to determine cloud similarity. The results may be filtered to optimize relevance, novelty and familiarity in accordance with preferences of the user. The recommended items may be displayed to a user interface. Users may interact with the user interface to steer the recommendations towards more relevant content. | 06-24-2010 |
20100161620 | Method and Apparatus for User-Steerable Recommendations - Method and apparatus for transparent, steerable recommendations. A steerable recommender uses tag clouds including descriptive tags and associated weights to generate recommendations. Users may dynamically interact with the recommender via a user interface to steer the recommendations. A tag cloud for an item is displayed, items for which associated tag clouds are most similar to the displayed tag cloud are identified, and the items are displayed as recommendations. The strength of similarity of the items to the displayed tag cloud may be displayed. The user may modify a tag cloud, for example by changing the weight of a tag or by adding or removing a tag, and the recommendations may be automatically updated to reflect the modification. A recommended item may be selected to display the tag cloud corresponding to the item. A user may select a user interface element to request information on why a particular item was recommended. | 06-24-2010 |
