Title: Linear predictive echo canceller integrated with relp vocoder.
Inventor: WANG DAVID TZAT KIN
IPC: H04B3/23
Filed: 1987-09-01
Abstract: A linear predictive echo canceller is integrated with a RELP vocoder in a two-way communications network, in which a received digitized speech signal synthesized by the RELP vocoder from a residual signal received with linear prediction coefficients is echoed onto a transmit channel and combined with a transmitted digitized speech input signal that is to be analyzed by a RELP vocoder for transmission. The echo canceller cancels the echoed signal from the transmit channel by generating a foreground transmit signal by subtracting a foreground estimate of the echoed signal from the combined signal; and providing the foreground transmit signal on the transmit channel for ananlysis by the RELP vocoder. In order to generate the foreground transmit signal, the echo canceller filters the received digitized speech signal with adaptation coefficients to generate the foreground estimate of the echoed signal; prewhitens the foreground transmit signal by using the received linear prediction coefficients; and generates the adaptation coefficients by cross correlating the received residual signal with the prewhitened foreground transmit signal and adding the product of said cross correlation to the adaptation coefficients used for generating the foreground estimate of the echoed signal.

Abstract: Un contacteur-disjoncteur (SW) d'une ligne d'alimentation en courant alternatif comprend un amplificateur (AMP) alimenté en courant continu pour appliquer des signaux détecteurs amplificateurs de commande au circuit de commande du contacteur-disjoncteur. Afin d'alimenter l'amplificateur en courant continu lorsque la principale voie de conduction commandée par le contacteur-disjoncteur est à l'état conductif, un enroulement primaire transformateur de courant (W1) est agencé en série avec cette voie et la tension se manifestant dans l'enroulement secondaire (W2) est redressée. Afin d'alimenter l'amplificateur en courant continu lorsque la principale voie de conduction commandée par le contacteur-disjoncteur est à l'état non-conductif, une tension à circuit ouvert associée à la tension qui se manifeste dans la voie non-conductive à circuit ouvert est redressée. Afin de pouvoir utiliser un redresseur (CR1) pour développer l'énergie en courant continu nécessaire à l'amplificateur, on applique avec avantage la tension à circuit ouvert à l'enroulement secondaire du transformateur de courant à travers un condensateur (C2) de blocage de courant continu ayant une impédance de courant alternatif suffisante pour restreindre le passage de courant par la voie à circuit ouvert du contacteur-disjoncteur.

Abstract: A high "g" protection system for a crewmember of an aircraft includes a seat and an upper torso support. The upper torso support is preferably secured to the crewmember's suit and to the seat. The torso support has a support plate and a support member which allow the crewmember to be supported and restrained while in a leaned forward or crouched position while enhancing the crewmember's tolerance to "g" forces. Another embodiment of the invention uses a pair of appropriately positioned armrests to provide torso support. The seat is provided with a repositionable seat pan which allows the crewmember's knees to be raised bringing him into a more crouched position or, conversely, allows the crewmember's knees to be lowered reducing the crewmember's angle of crouch, as may be desired.

Abstract: The rewinding device consists of a photoelectric cell (3) placed so as to receive ambient light, a capacitor (4) connected to the terminals of the cell, a stepping motor (6), and a control circuit (5). The input to the circuit is connected to the capacitor terminals and its output is connected to the terminals of the motor whose rotor is coupled to the clockwork spring, e.g. of a watch, in order to rewind it. 
<??>The cell (3) charges the capacitor (4) and when its voltage, measured by a differential amplifier (23), reaches a reference voltage (Vr), the capacitor is connected to the motor terminals by a switching transistor (27). The discharge of the capacitor supplies a driving pulse to the motor. The duration of the pulse is determined by a monostable flip-flop (25). After the pulse, the capacitor is once again charged by the cell. 
<??>In order to prevent the motor from receiving a driving pulse before being stopped, in the event of intense illumination of the cell, another monostable flip-flop (29) prevents the control of the switching transistor (27) for a period of time corresponding to the time required for the rotor to perform a complete step.

Abstract: The removal of the sealing membrane in the exit nozzle of cartridges occurs usually with the aid of a mandrel, with which the membrane is penetrated and the orifice thus made is widened, so that the pressing out of the substance can occur without difficulty. The new process is intended to permit an automatic removal of the sealing membrane from the flow path of the substance at the beginning of the pressing out procedure. The sealing membrane (38) located in the exit nozzle of the cartridge is opened by a relative movement between the cartridge (12, 13) and a coupling part (20) connected to the exit nozzles (30, 31) of said cartridge, by means of a cutting element (37) mounted on said coupling part, at least to such a degree that the sealing membrane (38) completely or partially releases the flow path for the substance as a result of the pressure exerted at the beginning of the pressing out procedure on the cartridge (12, 13) by the substance contained in it. <IMAGE>
