  • Device for addressing a cache memory of a compressing motion picture circuit
    Patent number: 5696698
    Abstract: A device for addressing a cache memory of a motion picture compression circuit, executing series of comparisons to estimate the motion of a current window of pixels of a current picture with respect to a reference window of a preceding picture, includes a first cache memory partitioned into four physical segments of equal size. Each physical segment is adapted to contain one half-macroblock of the reference window, and a circuit for addressing the first cache memory, the addressing being different for a motion estimation related to a current window of even rank and for a motion estimation related to a current window of odd rank.

  • Vehicle seat with adjustable seat part length
    Patent number: 5692802
    Abstract: A vehicle seat includes a seat part which is formed by a cushion secured to a first armature itself supported by a second armature on which the backrest is mounted, it being possible for the first armature to be moved back and forth with respect to the second armature. The first armature includes a rear part which is suspended from the second-armature by at least one rear connecting piece, and the first armature further includes a front part which is linked to the second armature by a front mechanism compatible with the rocking motion of the rear part of the first armature. When a user is seated in the seat, the first armature is urged backward by the weight of the user.

    Abstract: A magnetic device couples a main conductor of a TEM line and a waveguide forming a .lambda.g/2 resonator and procuring the propagation of an electromagnetic wave. The main conductor is fixed to a wall of the waveguide and extended by a pin inside the waveguide. The device comprises a tuning screw penetrating into the waveguide near the free end of the pin and perpendicular to the pin and an iris around and centered on the pin. The iris is closed on the side on the wall and its interior volume forms a zone in which the wave of the associated magnetic field is evanescent. The median axis of the tuning screw is in the plane of the aperture of the iris.

  • System and method using N-best strategy for real time recognition of continuously spelled names
    Patent number: 5677990
    Abstract: A multipass recognition strategy selects the N-best hypotheses resulting from each pass and propagates these N-best to the next pass. This strategy outperforms conventional hidden Markov model recognizers using a grammar constraining all possible names. Real time recognition of continuously spelled names is made feasible, in part, because the processor-intensive costly constraints are applied, if at all, in the 4th pass, after the system has produced a much smaller dynamic grammar.

  • Method of linearizing a non-linear amplifier, linearization circuit and amplifier including a circuit of this kind
    Patent number: 5675288
    Abstract: A linearization circuit for a non-linear amplifier optimizes the overall efficiency (>50%). To achieve high efficiency the amplifier is operated in class "E" or class "F" and near saturation, causing phase and amplitude non-linearity. Phase non-linearity is corrected conventionally by a phase error signal generated in a feedback loop. Amplitude non-linearity is corrected by operating on the power supply modulator of the non-linear amplifier in an open loop configuration, using the input signal power. Further, more refined correction of amplitude non-linearity can be effected by operating on an automatic gain control amplifier on the input side of the non-linear amplifier, the gain of the automatic gain control amplifier being controlled by an amplitude error signal generated in a feedback loop.
