摘要:
A method for preparing automated proof of publications and for supervising the publication of items in printed media, said method comprising: preparing a database including specifications for a plurality of items to publish, publishing said items on printed media using said specifications, scanning printed media pages or capturing an electronic file from a pre-press system including the published items, automatically extracting from the digitized pages identifying metadata characterizing said published items, using said identifying metadata to retrieve from a database the address to which said proof of publication should be sent, performing a quality control for controlling the quality of said published item by confronting the published item with said specifications, sending a proof of publication including at least the portion of said page including said published item to said address.
摘要:
An acoustic pressure gradient sensor able to detect a sound signal. The sensor includes a mechanical-acoustic device formed of a sphere that has omnidirectional sensitivity to the pressure gradient, an electromechanical device that accommodates the mechanical-acoustic device and that transforms the stresses into electrical impulses, and an electronic device to process the electrical impulses. The electromechanical device is formed of two printed circuits that incorporate low noise amplifiers. The printed circuits are separated by beams. The arrangement of the beams marks out a triangular structure. Each of the beams carries a gauge to measure the stresses.

The invention relates to a sensor for measuring three components of force and three components of moment. This sensor is comprised of one unitary mechanical piece comprising two end faces (1, 2) able to be secured respectively to a body generating forces and moments and to a reference body, and a central portion (7) comprising six beams (8) provided with means (12) for measuring deformations, arranged according to a closed triangular architecture between the two end faces (1, 2).
摘要:
The invention relates to a ventilation system for a convergent divergent exhaust nozzle in a bypass turbojet comprising an afterburn chamber surrounded by an annular passage through which circulates a stream of cooling air, a convergent divergent axisymmetric nozzle arranged downstream of said afterburn chamber, each circle of flaps comprising alternately a plurality of controlled flaps, and a plurality of follower flaps, a circle of cold flaps arranged radially outside said nozzle and hinged at their upstream end to a conical shell linked to the downstream part of the casing. The means of cooling the divergent flaps comprise an annular plenum chamber delimited downstream by said conical shell and fed with cooling air through drillings made in a boundary wall between said plenum chamber and the downstream end of said annular passage, a plurality of distribution cells surrounding the plenum chamber and linked to the latter, said cells being delimited downstream by said conical shell and being arranged around the X axis in the planes of symmetry of the follower flaps and telescopic pipelines each linking a cell to the follower divergent flap situated in the same plane of symmetry as said cell.
摘要:
A method and associated arrangement allows a content or service provider to establish an anonymous profile of a consumer using at least one request sent by the consumer through a communication network. The request sent by the consumer includes identification data of the consumer. The identification data is substituted in the network with an alias so as to anonymize the request. The identification data is not accessible to the content or service provider and there is a one-to-one and immutable correspondence between the identification data and the alias.
摘要:
A measurement sensor for a linking wrench between two mechanical parts and intended to enable a full force wrench with three force components and three moment components to be measured is provided. The sensor comprises six piezoelectric cylinders, whose axes are directed along six directions, two support plates mounted facing one another and respectively in contact with the two end faces of each piezoelectric cylinder, and screws to fasten the six piezoelectric cylinders between the two plates.
摘要:
The invention relates to a redundant robot of the modular type permitting displacement of a terminal from an initial position to a final position. This robot comprises a succession of stages (1.sub.i-1, 1.sub.i), each constituting a platform and six actuators arranged according to a closed angular architecture, a system of sensors associated with each stage, and control means permitting determining a configuration of the robot corresponding to the final position to be attained by the terminal and remotely operating the actuators for arranging the various stages according to this configuration. The control means comprises in particular means (26) for storing the space accessible by each platform, means (25) for inputting the final position to be attained, means (27) for computing the configuration of the robot, means (28) for computing the states of the actuators and a servo-interface for the latter.
