摘要： An encryption chaining mode takes (910) plaintext block N, generates (920) encryption key N by combining, preferably by XOR, encryption key N-1 and plaintext block N-1 and encrypts (930) plaintext block N using an encryption algorithm with encryption key N to output (940) ciphertext block N. Encryption key for the first plaintext block is generated by XOR-ing a random Initialization vector (IV) and a random initialization key K. In a preferred embodiment, initialization key K is subkeys resulting from a key schedule algorithm and encryption key N-1 is only one of the subkeys. Encryption key for the first plaintext block is generated by XOR-ing a random Initialization vector (IV) and one subkey resulting from a key schedule algorithm. Also provided is a corresponding decryption method, an encryption device (1110), a decryption device (1120).

摘要： The invention relates to an electronic module comprising a substrate (12), a frequency-tunable function on the surface of said substrate, a dielectric having a variable permittivity with electrical excitation in contact with said function, and a support (11) attached to the substrate so as to define the module, characterized in that the substrate includes a membrane (13), said membrane lying between an upper cavity (14) and a lower cavity (15) of the module, at least one cavity being filled with the dielectric, which may be a liquid crystal. The presence of two cavities, at least one of which is filled with a dielectric having a variable permittivity, makes it possible to increase the operating frequency range of the function.

摘要： The present invention relates to a method for detection of film mode or camera mode of a video sequence. This detection is carried out using histograms of video levels of frames of the video sequence. Difference histograms are calculated then compared with each other so as to generate difference parameters for each video frame of the sequence. The pattern formed by these difference parameters is then compared with predetermined patterns to deduce the mode, film or camera, of the sequence. The advantage of this method is that it requires just small memory resources for its implementation and can therefore be implanted in an FPGA circuit.

摘要： The invention concerns a method for synchronizing clocks of a set of nodes in a TDMA ( "Time Division Multiple Access" ) communication network comprising a plurality of nodes, among which some called time reference (TR) nodes are synchronized to a common time reference through a predetermined out-of-band synchronization mechanism, other nodes being called non-TR nodes, each node comprising an internal clock, characterized in that it comprises the steps of:
• transmitting, at the level of at least one of said TR nodes, a broadcast beacon packet during a given time slot of sub-frames, each sub-frame comprising a plurality of time slots ;
• propagating among the remaining nodes said beacon packet using the slotted structure of the TDMA protocol, each node being pre-assigned a conflict-free time slot in a sub-frame to broadcast said beacon packet received from another node in a previous slot of said sub-frame; and
• updating in at least two of said non-TR nodes the internal clock based on an updated offset estimate, upon reception of said beacon packet.
The invention also concerns a communication device in a TDMA communication network.

摘要： A method and apparatus for symbol timing in OFDM systems is described. It includes receiving an OFDM signal transmitted by a plurality of paths; correlating the received signal to do coarse symbol timing; and determining whether the coarse symbol timing needs to be adjusted based on a feedback from FEC decoder.
It finds application by detecting (720) pre-echo paths which are folded due the periodicity property of the IFFT (714).
The echo-identifier (720) fine-tune the timing of the FFT (706) by synchronizing on the far-most resolvable path which is likely to be a pre-echo.

摘要： Self-converging cathode ray tube with a deflection angle that is greater than 110°. The tube comprises a front panel supporting a luminescent screen surrounded by a flange perpendicular to the panel, the internal surface of the said panel being defined by radii of curvature Rdi along the diagonal, Rxi along the major axis and Ryi along the minor axis such that:
- 4 ≥ Rdi/d ≥ 2
- 0.8 ≥ Ryi/Rdi ≥ 0.4
- 1≥ Rxi/Rdi ≥ 0.7
Hence, the geometric distortion of the picture engendered by the self-converging deflection device is minimized, while enabling the shadow mask equipping such a tube to be less sensitive to thermal interferences.

摘要： In the different mapping planes, described by plane coordinates, of the color space in which colors to map are represented, a uniformity testing curve can be found that intersects all mapping trajectories of this mapping plane and, at any intersection of a mapping trajectory with said uniformity testing curve, the gradients calculated in said plane coordinates of the intersecting mapping lines and the first derivation along this uniformity testing of these gradient s are continuous.
Thank to the invention, colors are better preserved after mapping, even if there are different mapping methods in the same mapping plane.
