Title: Parallel mode adaptive transversal equalizer for high-speed digital communications system
Inventor: MIZOGUCHI SHOICHI
IPC: H04L25/03
Filed: 1990-01-17
Granted: 1993-07-27
Abstract: ABSTRACT OF THE DISCLOSURE In a parallel-mode adaptive transversal equalizer, P- and Q-channel data streams from A/D converters (1,5) are respectively passed through the tapped-delay lines of transversal filters (2,6), on the one hand, and are one-symbol delayed, on the other, by delay circuits (3,7,66,67) to produce (N-1) successively delayed P- and Q-channel data streams, which are respectively passed through the tapped delay lines of transversal filters (4; 63,8;64). In each transversal filter, symbols appearing at successive taps of the tapped-delay line are sampled and held for a duration of N symbols to produce first and second groups of stored symbols, the stored symbols of the first group being multiplied by first tap weights and summed, producing N first equalized outputs for each channel. The stored symbols of the second are multiplied by second tap weights and summed, producing N second equalized outputs for each channel. The first equalized outputs of each channel are respectively combined by adders (10-14,68,69) with the second equalized outputs of the other channel and multiplexed (14,15) into P- and Q-channel outputs. Correlations are detected by correlators (16-19, 70, 72) between data and error components of each of the P- and Q-channel outputs to control the first variable tap weights of associated tapped-delay lines, and correlations are detected by correlators (2-23, 71, 73) between data components of one of the P- and Q-channel outputs and error components of the other channel output to control the second variable tap weights of associated tapped-delay lines.

IPC: H01S3/097
Filed: 1990-09-18
Granted: 1994-04-12
Abstract: ABSTRACT OF THE DISCLOSURE     A pulsed light source comprising a laser for emitting light in pulse form in response to an electric power from a power supply which is changeable in accordance with a control signal from an external circuit and a photodetector responsive to the light from the laser so as to produce an electric signal corresponding to the intensity of the reception light.  The output signal of the photodetector is supplied to a comparator so as to compare the electric signal therefrom with a reference signal to output a signal proportional to the difference between the electric signal and the reference signal.  In response to the output signal of the comparator, a control circuit produces the control signal to be supplied to the power supply by adding the output signal of the comparator to a predetermined signal to control the electric power outputted from the power supply to the laser.

Title: Routing of network traffic using discrete traffic measurement data
Inventor: CHAUDHARY VED PRAKASH
IPC: H04M3/36
Filed: 1991-01-29
Granted: 1996-04-02
Abstract: A process is disclosed for routing service requests through a network (100) comprising nodes (101-104) interconnected with links. The network is also arranged so that each node may communicate with each of the other nodes. At preselected time intervals, sets of routes through the network are generated in response to the network configuration and traffic information. Also, at predetermined time intervals, occupancy factors are computed as determined by the network configuration and in response to traffic information. These occupancy factors are proportional to unassociated occupancy factors and allocation factors associated with calls of the various node-pairs; each of these latter factors is derived from a nominal routing scheme in which a call of the corresponding node-pair is treated as lost only if it is blocked on all of its permitted routes. At predetermined intervals, traffic usage data is measured. At regular intervals, the occupancy factors corresponding to the busy-idle status of the links are used to compute occupancy values associated with each of the routes. Occupancy values not exceeding a threshold generate sequential route sets for each interval. Offered traffic is sequentially routed over the sequential route sets.

Title: Method and apparatus for the combined use of dual density measurements to achieve a fast and accurate density measurement in pneumatically transported solids
Inventor: BASS RONALD MARSHALL
IPC: G01F1/86
Filed: 1991-04-22
Granted: 2001-05-15
Abstract: The suspension density of a pneumatically transported solid, such as coal, is obtained by using a combination of a radial gamma ray densitometer and a second, fast-response density metre. The combination is required to get the desired combination of accuracy and response time. The second measurement is used for its fast response time and may be used to control operating conditions of a gasifier. The slower, but more accurate, radial radiation measurement is used to recalibrate the second measurement approximately every 10 seconds and correct for drift thereof. The drift in the second measurement is sufficiently slow that high accuracy can be maintained by the recalibration technique.

Selon le procédé, on fournit en continu le matériau de départ et le réactif à une colonne de distillation en continu à étages multiples afin de provoquer la transestérification entre le matériau de départ et le réactif en présence d'un catalyseur et on extrait en continu de la partie inférieure de la colonne, sous forme liquide, le carbonate aromatique ou son mélange, qui se forme en tant que produit à point d'ébullition élevé, tout en retirant en continu de la partie supérieure de la colonne, par distillation et sous forme gazeuse, les produits secondaires à point d'ébullition réduit, afin d'obtenir la transestérification entre le matériau de départ et le réactif. Ce procédé permet d'obtenir avec un rendement élevé, à une vitesse élevée de réaction, un carbonate aromatique utile comme matériau de départ pour produire un polycarbonate aromatique ou différents isocyanates, sans qu'il soit nécessaire d'utiliser du phosgène toxique.
