Abstract: Radio frequency device including at least: a tube through which a channel passes, a front face and/or a rear face forming a bearing surface through which the channel passes, the bearing surface forming an annular frame around one end of the tube and being integral with the tube. The bearing surface includes axial fixing apertures passing through the bearing surface and opening outside the channel in order to allow fixation of the device, and the width of the frame being greater at and in the immediate vicinity of the axial fixing apertures than at a distance from these axial fixing apertures.

Abstract: The present invention relates to a method for determining positions by an optronic system in a scene, the scene comprising reference elements of known geographic coordinates, the optronic system comprising the following elements integrated into said optronic system: a. a digital imager, b. a memory wherein is stored, for each reference element of the scene, an indicator representative of said point associated with the geographic coordinates of said point, c. a display element that displays the indicators stored in the memory, d. a measurement module comprising at least one element chosen from among: a compass, a goniometer and a telemeter, e. a calculation unit, the method being implemented by the elements integrated in the optronic system.

Abstract: Method for verifying a display of images on an electronic screen, comprising the following steps: displaying one image on the electronic screen; measuring one value of a display parameter during the display of the image; comparing the measured value of the display parameter with one reference value corresponding to one reference image; and if the measured value corresponds to the reference value, determining that the displayed image corresponds to the reference image. An electronic screen based on light-emitting diodes is used, and a power consumption of a portion of the electronic screen is used as the display parameter.

Abstract: A control and communication unit is provided between a terminal and at least one microcircuit card. The unit includes a control module for a number of input signals to the card; a module for generation of a number of time diagrams for the card communication protocols; a request generation module for transmission and reception of characters based on information received from the control module, the requests being transmitted to an external module; and an interruption generation module for creating an interruption in the case of an error in a time diagram or a character received or transmitted, based on information received from the control module and for processing the interruption without a loss of characters. The generation of an interruption does not cause an interruption in the process of request generation.
