Abstract: The present invention relates in particular to a synchronization system and method. The synchronization system comprises a specification unit for specifying synchronization signals associated with an audiovisual program, the latter comprising an audiovisual content and control information, a recognition unit for recognizing the synchronization signals in a transmitted stream carrying this program, by recognition of at least one extracted portion of the audiovisual content, and an activation unit triggering an action in case of detection of these signals. The specification unit prepares and transmits to the recognition unit recognition elements making it possible to obtain this extracted portion, as well as at least one action timeout lag in case of detection of the synchronization signals. The recognition or activation unit then delays the triggering of this action according to the lag transmitted, in case of detection of the synchronization signals.

Abstract: A transponder includes an integrated circuit (1) and an antenna (5) which is electrically connected to the integrated circuit (1) in a removable manner, the removable electrical connection including at least one intermediate connection element (4). The removable connection, together with the intermediate connection element (4) between the antenna (5) and the integrated circuit (1), can be used to divide the transponder into two parts. Moreover, the intermediate connection element (4) can also be used, in one variant, to reinforce mechanically at least one part of the contact elements (40), while facilitating the precise fixing of the contact elements to the corresponding element of the object to be marked.

Abstract: An electronic label (1) is used to mark a container (2, 6). The label includes a radio identification element (RFID, Radio Frequency Identification Device) (10, 11) and which is intended to be placed inside the container (2, 6). The electronic label (1) is specifically adapted to the position thereof inside the container (2, 6). Using the present arrangement, the electronic label (1) is inaccessible and, thus, difficult to destroy or change. In this way, the container (2, 6) is marked in a reliable, even permanent, manner, thereby enabling the information contained on the label (1) to be used effectively to combat theft, forgery or counterfeiting and to manage a deposit system.

Abstract: Back of a watch case including a cover (4) that defines the external surface of the back, and a false back (11) that is mounted against the internal surface of the cover. The false back can be provided with an engraved decoration and can be manufactured by stamping from a plate of even thickness. A transponder can be housed between the cover and the false back.

Abstract: The interactive multimedia devices is based on network structures involving: a broadcasting network (120) and a return path network (140). On the broadcasting network, the interactive data are multiplexed with the broadcast audiovisual signals so as to offer interactivity to connected end-users on the return path network. To address specific sociological profiles, and to save bandwidth, a plurality of filters, let's say a number N, is associated with a single interactive application. In such case, the comparison continues until one of the N filters match the profile stored in the terminal permanent memory. If one of the filters matches the viewer's profile, the interactive application is executed, else the application is ignored. In this way, a plurality of categories of viewers can interact. A plurality of filters can be associated with an interactive application with different contents. To each filter corresponds a content.

Abstract: The invention relates to a process for controlling the flow of information exchanged between at least one station for transmitting interactive programs and a plurality of interactive terminals. According to the invention, during each interactive program, each terminal is sent a group of data intended to set up a protocol for establishing interactive communications between said transmission station and said terminals.

Abstract: For measuring the flow rate of a thin stream of molten materials such as that of glass, the diameter of the thin stream is measured, as is the velocity. The velocity is measured on the basis of the measurement of the time separating the successive appearance of an emission sequence emitted at first and second points on the path of the molten material. A correlation is then established between the sequences and the time interval corresponding to the passage of the same irregularities at the two selected points identified by this correlation.

Abstract: The invention relates to the analysis of defects in materials such as molten glass. According to the invention, the material passes by a monochrome beam the wavelength of which is below 3.times.10.sup.-6 m. The radiation is diffused by any defects present in the material. The analysis of the defects is conducted dependent on the position of the receiver detecting the diffused rays and on the shape of the signal received. The invention permits a continuous analysis of a flow of glass supplying a fiber-making machine.
