摘要： The invention concerns a clock recovery method in digital signal sampling, the clock being generated from a phase-locking loop or PLL (1) which multiplies a given frequency by a whole number. Said method comprises a step which consists in comparing the relative position of the signals with respect to the clock so as to determine whether a selected type of the clock transitions is in phase with the same type of signal transitions by: producing (6) over a clock period several zones, one zone corresponding to the selected type of transitions; analysing (5) the signal transitions relatively to the clock uplink or downlink transitions; cumulating in the corresponding zone the analysis results; determining (10, 9) on the basis of the accumulation whether the sampling clock frequency and/or phase needs to be modified or not. The invention is applicable to signals derived from graphics cards.

摘要： The invention relates to a method of manufacturing a colour cathode-ray tube, in which a graphite coating (22) of variable thickness is interposed between the glass faceplate (2) of the tube and the phosphors (25, 26, 27) intended to reproduce a colour image. The purpose of the coating (22) is to reduce the transmission of the glass, of which the faceplate is composed, to a defined value.

摘要： An optical pick up as used for example in an optical disk player comprises a lens holder, a body (15) of which may support a lens (8). The body is moved in an externally applied magnetic field using a coil (20) rigidly fixed to the body. The movement occurs when a current flows in the coil. The body comprises a cavity (18) delimited by a cavity wall (19). The coil is fitted inside the cavity such that a whole circumference of the coil is in contact with the cavity wall. The coil body assembly shows an improved stiffness which allows to move the lens holder at relatively high frequencies.

摘要： 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. The information provided by the viewers is homogenized owing to a standardized format stored in the terminals and in the service provider viewer database. In this way, it is possible to select a specific terminal or a category of viewers by using their profiles and not by using their physical addresses and to allow the viewer to react in a very short time in an interactive application mainly for interactive applications dedicated to commercial purposes. To address specific sociological profile, and to save bandwidth, a criteria file called a filter is attached to the digital data multiplexed with the audiovisual signals. Then, each operational interactive terminal receives the digital data with an attached filter. The interactive terminal applies the script of the filter to the criteria included in the filter and to the criteria contained in the viewers profile registered during the installation phase in order to enable the interactive connection.
In another implementation, 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. These contents are displayed if the corresponding filters match the viewers profile.
