Abstract: An encoder operable to filter audio signals into a plurality of frequency band components, generate quantized digital components for each band, identify a potential for pre-echo events within the generated quantized digital components, generate an approximate signal by decoding the quantized digital components using inverse pulse code modulation, generate an error signal by comparing the approximate signal with the sampled audio signal, and process the error signal and quantized digital components. The encoder operable to process the error signal by processing delayed audio signals and Q band values, determining the potential for pre-echo events from the Q band values, and determining scale factors and MDCT block sizes for the potential for pre-echo events.

Abstract: A cam includes a cylindrical ring having a substantially circular outer section and, externally, a helical running track. The ring has a conduit that connects two ends of the external helical running track, and the conduit includes a track for recirculation between the ends of the running track.

Abstract: This locking device for an electromechanical actuator comprises a rod that is movable relative to a cylinder under the action of a motor actuating the rod, an assembly of at least one hook that can be moved between a locked position in which said hooks engage in an indentation and an unlocked position in which said set of hooks is released from the indentation, one of said set of hooks and the indentation being provided on the cylinder and the other on the rod. It comprises a sliding lock that can slide relative to said hooks and to the indentation between a holding position in which said hooks are held in the locked position a released position in which said hooks are released under the action of the motor actuating the rod.

Abstract: The invention relates to a method for monitoring the output of an electromechanical actuator of the rotary-linear type in order to detect a gradual seizing thereof, wherein said method comprises: measuring the intensity, representative of the motor torque, of the electrical current powering an induction winding of the actuator and the axial stress undergone by an actuator rod; calculating the ratio (axial stress undergone by an actuator rod/motor torque) representative of the global output of the actuator and of its present state; and generating an evaluation of the present condition of the actuator based on its present state and optionally on previous stored states and on outer parameters.
