Abstract: The present invention relates to a locking device including: a crown provided with a bore, a hub, mobile in rotation relative to the crown, a plate, integral with the hub, a rocker, mobile in rotation between a locking position and a release position, a groove, opening onto the bore and formed in the rocker or the plate, a guide ramp, formed at a periphery of the rocker or the plate, a pin, mounted in the groove to be blocked between the bore and the guide ramp when the rocker is in the locking position, and a return spring, acting between the plate and the rocker to bring the rocker back to the release position.

Abstract: A method for controlling memory access for an embedded computer program, during the development phase, the computer program being executed in a device comprising a memory unit, the memory unit comprising a payload storage space and a corresponding space for storing error detector or corrector codes, the method comprising storing a state indicator in a location of the error code storage space, the stored state indicator being independent of a payload stored in a corresponding location of the payload storage space and being representative of a state of the location of the payload storage space, and detecting a memory access error in a location of the payload storage space depending on a state indicator stored in a corresponding location of the error code storage space.

Abstract: In an embodiment a device includes a first circuit configured to send a signal comprising numbers successively separated by a constant value to at least one second circuit, each second circuit being in a clock domain different from a clock domain of the first circuit and at least one third circuit configured to determine whether the successive numbers of the signal received by the second circuit are separated by the constant value, wherein the signal is sent to a respective third circuit in each of the clock domains different from the clock domain of the first circuit.

Abstract: The method of estimating the relevance of a document with respect to a concept comprises calculating (32) a relevance function of the concept with respect to said document on the basis of a known predetermined semantic neighborhood of the concept. It further comprises calculating an ambiguity function of said concept in said document, which ambiguity function is different from the relevance function, said calculation being an estimation based on the presence in the document of different meanings of the concept. The method follows on from a preliminary step of detecting ambiguous concepts in a database.

Abstract: This system for predictive analysis of digital data time flows associated with text information (18) comprises means (12) for automatically predicting values (24) of a digital data time flow from past values (22) of said flow. It further comprises means (14) for analyzing text information (18) to supply the prediction means (12) with a weighted concept vector (20) associated with the past values (22) of the digital data time flow.

Abstract: The indexing and search system comprises means (10) for storing an indexing base (24), means (22) for indexing resources (18) to create and update the indexing base (24), means (40) for searching for resources and adapted to interrogate the indexing base (24) on the basis of a request, and request-extender means (38) for obtaining an extended request on the basis of an initial request (34) formulated by a user and including initial terms (R1), by adding to said initial request (34) terms which are neighbors to the initial terms. The extender means (38) further comprise means (36) for limiting the extension of the initial request by adding thereto only terms that are neighbors to initial terms that are not general, i.e. Terms that do not have too great a number of neighbors. Means (20) for generalizing indexing may also be implemented in the invention.
