摘要： The delay element consists of a differential amplifier (M15, M8, M2, M6, M5) in which the load transistors (M2, M5) are associated to respective gate biasing transistors (M21, M22) connected in a source follower configuration, and to feedback transistors (M3, M4), which implement a negative impedance in parallel to a positive impedance represented by each of the load transistors (M2, M5). The modulation of the delay is achieved by modulating the bias currents of the load transistors (M2, M5), the feedback transistors (M3. M4) and the gate biasing transistors (M21, M22).

摘要： A method and an apparatus for the animation, driven by an audio signal, of a synthesised human face model are described, that allow the animation of any model complying with the ISO/IEC standard 14496 ("MPEG-4 standard"). The concerned phonemes are derived from the audio signal, and the corresponding visemes are identified within a set comprising both visemes defined by the standard and visemes typical of the language. Visemes are split into macroparameters that define shape and positions of the mouth and jaw of the model and that are associated to values indicating a difference from a neutral position. Such macroparameters are then transformed into face animation parameters complying with the standard, the values of which define the deformation to be applied to the model in order to achieve animation.

摘要： The method and the apparatus allow coding, manipulation and decoding of audio signals independently of the specific signal content. An encoder (AC) carries out an object-oriented coding and generates a coded signal, with variable bit rate and bandwidth, comprising a basic layer and one or more enhancement layers for each object. The encoder (AC) is able to operate according both to ad hoc algorithms and to any standardised algorithm and selects the most convenient algorithm depending on the object to be coded. Bit stream manipulation units along a transmission path towards a decoder (AD) allow scaling the bit rate or the bandwidth of the coded signal or altering parameters of the coded signal by acting on individual objects.

摘要： A reactor is described where the substrates (W) subjected to the deposition process are maintained in a substantially vertical position and are imparted a relative motion with respect to the nozzles (26) whence the carrier gas that carries the deposition reactants exits. Preferably the reactor presents an altogether cylindrical shape, with the substrates (W) mounted on a carousel structure (7) rotating around a main axis (X8) coinciding with the main axis of the case of the reactor. The diffusion of the carrier gas and of the reactants is effected starting from a head (11) which projects from the vault of the case of the reactor and which extends inside the carousel structure (7) where the substrates (W) are mounted. The head (11) presents a plurality of nozzles (26), uniformly distributed on its periphery, for the release of the carrier gas and of the reactants borne thereby. Preferred application for the deposition of semiconductors starting from metal-organic reactants in vapour phase, in particular for integrated optics applications.

摘要： A method and an apparatus are provided for introducing reference impairments into pictures to be used in subjective tests on digital video signals, in compliance with ITU-T Recommendation P.930. The method generates blockiness distortion and/or edge busyness distortion. For the first distortion, areas close to picture edges are selected and, through a movement characteristics analysis, blocks are identified that belong to said areas and that are concerned only by the actual movement of the subject and, for blocks chosen among the identified ones, the luminance value is replaced by a value linked to the individual pixel luminance and to the average block luminance value. For the second distortion, echoes are applied that are randomly chosen in a prearranged set and that alternate at random.
