Title: Procede et appareil de conversion directe numerique-rf faisant intervenir la mise en forme des impulsions
Inventor: SARCA OCTAVIAN V
IPC: H03D7/00
Filed: 2002-09-12
Abstract: Cette invention concerne un procédé et un appareil permettant d'effectuer une conversion directe numérique-IF/RF à l'aide de la mise en forme des impulsions. Ce procédé permet d'obtenir un spectre de sortie plat ou sensiblement plat après une conversion numérique-analogique avec un minimum de perte d'énergie de signaux. Contrairement à la réduction d'impulsions, qui consiste à réduire l'impulsion de sortie du convertisseur numérique-analogique (CNA) et de ce fait l'énergie par échantillon à une fraction a<1 du maximum, la mise en forme des impulsions ne réduit pas l'impulsion du CNA. Pour chaque échantillon, la mise en forme des impulsions stocke d'abord l'énergie fournie par le CAN puis libère l'énergie stockée à la sortie pendant un court laps de temps aT. Ainsi, on ne perd que très peu d'énergie de signaux, même pour de très basses valeurs de a. La mise en forme des impulsions permet à la durée aT de l'impulsion de sortie de contribuer à la planéité spectrale d'une façon semblable à la réduction des impulsions, mais présente par ailleurs l'avantage de voir la forme de l'impulsion de sortie contribuer de manière très importante à la planéité spectrale. Deux modes de réalisation du procédé de mise en forme des impulsions sont décrits dans le contexte de deux types de CAN qui sont utilisés, dans le premier cas, avec un courant de sortie, et dans le second cas, avec une tension de sortie. Deux exemples d'application de mise en forme des impulsions sont également donnés pour un CAN à courant de sortie unique ainsi que pour un CAN à courant de sortie différentiel.

Title: Picosecond multi-harmonic fourier fluorometer
Inventor: MITCHELL GEORGE W
IPC: G01J3/443
Filed: 1990-01-16
Abstract: LBl68812578 ABSTRACT OF THE DISCLOSURE         A frequency domain spectrofluorometer employing extrinsically modulated DC light sources or intrinsically modulated laser pulse trains, containing multiple, harmonically related, phase-locked frequencies for exciting a fluorescent sample.  High frequency light emissions of the excited sample are simultaneously cross-correlated with multiple, harmonically related, phase-locked R-F frequencies to produce workable low frequency electrical detector signals having the same phase and modulation characteristics as the multiple frequency sample light emissions.  The detector signals are digitized in a computer and transformed from time to frequency domain by complex fast fourier transforms to extract the phase and modulation data for all frequencies of the sample light emissions.  This data is displayed simultaneously on the visual presentation screen of the computer.

Abstract: MULTILAYER STRUCTURE HAVING A LAYER COMPRISED OF A BLEND OF POLYPHENYLENE ETHER AND               HIGH IMPACT POLYSTYRENE                 ABSTRACT OF THE DISCLOSURE A multilayer packaging structure for microwave food reheating applications or for sterilized hot filling is provided having an outer layer prepared from  a  blend  of  polyphenylene  ether  and  a  high impact  polystyrene.   The  polyphenylene  ether-high impact polystyrene layer is useful as a structural support layer and provides resistance to distortion and burn through during microwave reconstitution or hot filling.   The PPE/HIPS  blend  layer serves  to increase  the  high  temperature  performance of the coextruded   structure   without   sacrificing   the thermoformability     characteristics     generally associated with HIPS based monolayer or multilayer structures.    The  ethylene   vinyl   alcohol   or polyvinylidene  chloride  layers  act  as  the oxygen barrier to prevent food spoilage and the polyolefin layer acts as a moisture barrier.

Patent CA-2016226-A1 (CA)
IPC: H04M15/00
Filed: 1990-05-07
Abstract: A voice message system for a pay phone telephone network interposes an Intercept Processing Subsystem (25) in the line connections (22) between the pay telephones (11) and the central office (10).  A Voice Processing Subsystem (16) is connected to the central office switch (14) by a trunk (17).  A caller at a pay station enters a called telephone number (55) which is stored in the Intercept Processing Subsystem (25, 56). The Intercept Processing Subsystem monitors the line connection to determine if the called telephone remains on-hook for a predetermined number of ring tones or is busy for a predetermined number of busy tones (82).  If the ring no answer or busy condition maintains, the Intercept Processing Subsystem reduces the volume of the ring or busy tones on the line connection and superimposes a voice announcement thereon offering the voice message service to the caller (83).  If the caller enters an acceptance key sequence or coin deposit (84), the Intercept Processing Subsystem splits the line connection (101), sends a Thank You message to the calling telephone (104) and speed dials the Voice Processing Subsystem (109).  When the Voice Processing Subsystem answers (114), the Intercept Processing Subsystem sends a voice prompt to the calling telephone explaining that at the tone a voice message may be entered and delivery thereof will be attempted at predetermined intervals for a predetermined time (115).  Simultaneously, with sending the voice prompt to the caller, the Intercept Processing Subsystem transmits the call parameters to the Voice Processing Subsystem (115) utilizing a protocol with interleaved validity acknowledgement signals from the Voice Processing Subsystem.  If the transmission of the call parameters is valid (116), the Intercept Processing Subsystem reestablishes the line connection between the calling telephone and the central office switch and the voice message from the caller is passed through the Intercept Processing Subsystem to the Voice Processing Subsystem for recording thereat (118) for subsequent delivery to the called station (124).

IPC: H03K17/0814
Filed: 1990-09-12
Abstract: ABSTRACT      An electrical circuit for the switch-off relief of a controllable semiconductor switch.     Electrical circuits are known for the switch-off relief of  controllable  semiconductor  switches,  in particular disconnectable  thyristors  or  gate  turn-off  switches arranged  in parallel  with  a series arrangement of a storage  capacitor  and  a  diode.  In these circuits a discharge switch is driven by a control arrangement and can  close  a  discharge-current  circuit  connecting  the capacitor to the primary winding of a transformer so that energy  stored  in  the  capacitor  can be tapped at the secondary  winding  of  the  transformer.  In  the present invention the control circuit is connected to the input side of the diode and constructed in such a way that the discharge switch is driven depending upon the polarity of the  voltage  across   the  diode.   In  addition,   the transformer is preferably driven as a blocking converter.

Title: Method and system for controlling an external machine by a voice command
Inventor: NAKANO FUMIO
IPC: G10L15/00
Filed: 1991-01-30
Abstract: In a method for controlling an external machine by a voice command, a voice pattern which is extracted from a voice supplied through a microphone is compared with reference voice patterns to pick up one of them which corresponds to a certain voice command to control an external machine,  and a similarity between the voice pattern and the reference voice pattern is calculated.  Then, a control signal is supplied to the external machine after a waiting time passes.  The waiting time is determined dependent on the similarity such that the waiting time is relatively long when the similarity is low and is determined relatively short when the similarity is high, so that an operator has a sufficient time to judge whether the voice command is the desired one.
