Abstract: A method for producing a composite sulphur/carbon conductive material obtained solely from an initial sulphur and an initial carbon which includes the following successive steps between 50% and 90% by weight of initial sulphur and between 50% and 10% by weight of initial carbon having a specific surface smaller than or equal to 200 m2/g are placed in a reactor at atmospheric pressure, the sum of the proportions respectively of the initial sulphur and carbon attaining 100%, the reactor is hermetically sealed at atmospheric pressure, and the composite sulphur/carbon conductive material is formed, in powder form, by heat treatment by heating said reactor to a heating temperature comprised between 115° C. and 400° C., without external regulation of the pressure inside the reactor, and keeping said reactor at said heating temperature during a predetermined time.

Abstract: An electronic device is arranged to receive a removable wireless remote data transmission accessory, in particular of the 3G “stick modem” or Wifi type, the accessory including an accessory body, at least one radio antenna, an accessory connection element linked to the accessory body, the device including a device connection element, arranged to connect with the removable accessory and to be coupled with the accessory connection element, characterized in that the device is arranged to receive the removable accessory in a slot, the device being structured so as to allow the radio antenna to transmit data remotely when the accessory body and/or the radio antenna is at least partially inserted in the slot, in an active data transmission position of the accessory. The invention relates in particular to devices receiving removable accessories of the “3G modem” or “Wifi” type.

Abstract: A device for remotely controlling functions of a digital multimedia player-recorder that is connectable to a network, and a system in which the device is implemented

Abstract: A portable digital terrestrial television device comprises a portable digital terrestrial television apparatus and means for receiving a low power digital signal. The reception means (30, 31) comprise two antennae for receiving the digital signal, the relative disposition of the antennae being adapted to reduce the coupling between said antennae, said antennae being borne by a support (9, 10, 81) comprising means for connecting the antennae to the portable digital terrestrial television apparatus.

Abstract: A light box for X-rays is made by using a graphics screen (20) coupled to a microprocessor (23), with the screen being used with inverse brightness. Under these conditions, the graphics screen emits light at nearly all points, other than special locations (I.sup.25) whose positions can be controlled by means of a control box (24). An X-ray negative (6) to be examined is placed over the graphics screen. The control box is used to move the non-illuminated regions of the screen to point to special locations in the negative. The light box is particularly applicable t studying stereographic negatives for mammography. It makes it possible to determine more quickly and more accurately the locations of lesions in breasts under examination.

Abstract: Disclosed is a radiology system of the mammograph type in which there is provision for a radiation controller. The invention lies in the fact that the input aperture of the detector is masked by a belt that absorbs the X-radiation except at zones, the variable dimensions of which are designed to get adapted to the different shapes of breasts. The belt is driven by a motor 24 and stops at the practitioner's command so that the appropriate zone is in correspondence with the input aperture of the detector 22.

Abstract: Disclosed is a radiology system of the mammography type wherein there is provision for a radiation controller having a detector of X-radiation having gone through the breast to be observed, of the type having a converter of X-radiation into photon radiation and a photomultiplier tube for the amplifications of photons emitted by the converter. The invention lies in the fact that the converter is masked by a belt opaque to the photon radiation except in the zones for which variable dimensions are planned so as to get adapted to the different shapes of breasts. The belt is driven by a motor which is turned on and off at the practitioner's command, so that the appropriate zone is in correspondence with the converter.
