Title: Improved adsl compatible discrete multi-tone apparatus
Inventor: CIOFFI JOHN M
IPC: H04L27/00
Filed: 1995-04-14
Abstract: A transmission scheme contemplates encoding and modulating digital data onto a discrete multi-tone signal having a total banwidth of at least 1.6 MHz. The modulation system dynamically updates the subcarriers used and the amount of data transmitted on each subcarrier during transmission (215, 217, 219). In one embodiment, the multi-tone encoding and modulation complies with the ATIS North American Asymmetric Digital Subscriber Lines standard. However, additional subchannels (a total of 512) and/or subchannel bandwidths of greater than 4.3125 kHz may be used. In this system, the subchannels occurring above frequencies set forth in the standard are treated similarly to those within the standard range in terms of subcarrier selection criteria. This system permits transmission of digital data at transmission rates of 6-55 Mbps over twisted pair lines at distances of 1200 meters on lines experiencing significant crosstalk noise such as T1 or E1 (215, 217, 219) as well as at transmission rates of 10-50+Mbps over distances of 2000 meters.

Title: Method and system for compensating for coupling between circuits of quaded cable in a telecommunication transmission system
Inventor: LECHLEIDER JOSEPH WILLIAM
IPC: H04B3/46
Filed: 1995-04-27
Abstract: Coupling between two side circuits and a phantom circuit in a quaded cable (200) is compensated for at the receiving end of a transmission system.  Known signals are separately transmitted on each circuit and coupling between each circuit is estimated based on a measured signal received at the receiving end of the quaded cable for initialization.  During data transmission, received data signals are modified in accordance with the initially determined coupling to produce estimated transmitted data signals.  Reestimation of the coupling between each circuit is performed during data transmission by storing (303) N received data signals and N estimated transmitted data signals on each circuit.  The coupling between circuits is determined as a function of the covariance of the N received signals and covariance of the N estimated transmitted signals on each circuit.  The reestimated coupling is used to modify (302) subsequent received data signals on each circuit.

Title: Multimedia information service access
Inventor: MORTENSON ROBERT F
IPC: H04N21/6543
Filed: 1997-04-07
Abstract: Real time delivery of multimedia information accessed either through the Internet, or otherwise, simultaneously, or sequentially time delayed to one or more users, is enabled by delivering the multimedia information over a switched network via a multipoint control unit. A client establishes a connection with a server, or other remote location where desired multimedia information is resident, identifies the desired multimedia information and provides client information identifying the locations of the users. The client information may include the telephone numbers or other access numbers of each of the multiple users. The multimedia information is then delivered by a multimedia server to a bridging apparatus through a switched network guaranteeing high quality of service, secure connection and billing control. Connecting one or more users to a live agent is also made possible by providing the telephone numbers of the users and the live agent directly to the multipoint control unit. The delivery of the multimedia information can be secured by comparing the client information to a segmented "to call" list to determine whether the client is authorized to receive the requested multimedia information. Alternatively, or in addition, security can be implemented by mounting a video camera at the client's endpoint and connecting a database running face recognition software to the multimedia server. The multimedia server's call to the user triggers the camera to take a picture of the user. The selected content is restricted to authorized users by comparing the picture to pictures of authorized faces stored in the database.

Title: Hydrocarbon gas processing
Inventor: HUDSON HANK M
IPC: F25J3/02
Filed: 1995-11-06
Abstract: A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is divided into first and second streams. The first stream is cooled to condense substantially all of it and is thereafter expanded to the fractionation tower pressure and supplied to the fractionation tower at a first mid-column feed position. The second stream is expanded to the tower pressure and is then supplied to the column at a second mid-column feed position. A recycle stream is withdrawn from the tower overhead after it has been warmed and compressed. The compressed recycle stream is cooled sufficiently to substantially condense it, and is then expanded to the pressure of the distillation column and supplied to the column at a top column feed position. The pressure of the compressed recycle stream and the quantities and temperatures of the feeds to the column are effective to maintain the column overhead temperature at a temperature whereby the major portion of the desired components is recovered.

Abstract: Un actionneur (10) développe un déplacement à partir d'une force; l'actionneur utilise des éléments de tension actifs (20) qui comprennent une fibre ou des fibres qui se rétrécissent lors de l'activation, par exemple des fibres d'alliage à mémoire de forme; la fibre ou les fibres sont entraînées entre les éléments de support opposés espacés entre eux (12, 26), en général un empilement de disques espacés; la fibre ou les fibres entraînées définissent u ne cage de longueurs de fibres qui s'entrecroisent selon un agencement symétrique, d'une manière caractéristique un agencement hélicoïdal. L'activation des fibres a pour effet de raccourcir les longueurs de fibres et de produire un déplacement relatif des éléments de support et dont la translation permet le déplacement d'un composant auquel l'actionneur est effectivement relié; dans un autre mode de réalisation, les éléments de tension actifs s'étirent sous la contrainte, de sorte qu'au lieu d'un actionneur, on obtient un amortisseur qui élimine un déplacement par une force.

Inventor: BRAMBACH JOHAN ARIE
IPC: B60P3/24
Filed: 1996-01-26
Abstract: A container (1) for fluids, in particular fluids containing gas, comprises an outer casing (2) of flexible, pressure resistant material, at least a gas and/or fluid tight inner casing (3) of flexible material lying inside the outer casing and being separated therefrom, and at least a filling connection (4) for filling the inner casing.   As a result, the container (1) is collapsible so that filling the container may take place from the collapsed condition and filling is therefore possible without pressure difference while the fluid does not enter an empty space. The egress of gas from the fluid is substantially reduced thereby. When fluid is discharged from the container (1), the volume of the container can also decrease by collapsing so that also during use of the fluid gas is prevented from egressing.   Consequently, the quality of the fluid is maintained, both during filling of the inner casing with fluid and during discharge of fluid from the inner casing. When the container (1) is completely empty, it is collapsible in a flat manner and occupies only little room, which is very favorable for transport and storage.
