Title: Method and system for transferring digital data calls between different destinations
Inventor: FEURY PATRICK J JR
IPC: H04L45/28
Filed: 1999-07-13
Abstract: Systems and methods for handling different types of alarm signals, such as red, blue, and/or yellow alarm signals, in hybrid time division multiplexing (TDM)/asynchronous transfer mode (ATM) networks. A terminal adapter, which may be in the form of a stand-alone device and/or integrated with an ATM switch, may receive an alarm signal from a TDM switch. Based on the nature of the alarm signal, the terminal adapter may send a message to the ATM switch and/or acknowledge to the TDM switch that the terminal adapter has received the alarm signal from the TDM switch. The ATM switch, upon receiving the message from the terminal adapter, may route appropriate other messages to other ATM switches and/or TDM switches in the hybrid network. Other ATM  switches receiving such messages may in turn route appropriate messages via the signaling network to other ATM switches and/or TDM switches.

Patent CA-2299644-A1 (CA)
Inventor: ELLYIN FERNAND
IPC: B29C70/86
Filed: 2000-02-25
Abstract: A steel liner (a pipe or vessel) is wrapped with a stack of sheets of glass fiber-reinforced epoxy matrix composite arranged in angle-ply pattern.  The stack is cured on the liner to bond the sheets together and to the liner.  The wrapped liner is then internally pressurized to cause the liner to yield while the composite remains elastic. When de-pressurized, the liner has compressive residual stress and the composite has tensile residual stress.   When the resulting hybrid structure is subsequently again pressurized, it is found that the elastic regime of the liner has been extended.

Title: Apparatus and method for integrating error control and authentication for satellite uplinks
Inventor: CASO GREGORY S
IPC: H04L1/00
Filed: 2000-03-14
Abstract: A method and apparatus (200) for generating a sender authenticatable codeword (152) for transmission in an uplink to a satellite are presented. A method and apparatus (202) for authenticating a codeword (152) transmitted in a satellite uplink are also presented. The generation of a sender authenticatable codeword (152) is performed by combining an information block (143) and an authenticating filling sequence block (144). A parity block (148) is formed over the combined block (146) and the resultant true codeword (150) is truncated to remove part or all of the authenticating filling sequence block (144).      Authentication of the codeword (152) is performed by receiving an observable (152') and combining an authenticating filling sequence block (144') with the observable (152') to form an extended observable (150').      The extended observable (150') is decoded and a decoded observable and an error rate estimate formed. Authenticity is then determined based on the error rate estimate, which may be an error rate estimate for the authenticating filling sequence block (144') portion of the decoded observable (154').

Title: Catheter having a high tensile strength braid wire constraint and method of manufacture
Inventor: BERG TODD A
IPC: A61M39/10
Filed: 1998-08-20
Abstract: A tubing assembly for manufacture for a catheter of the type having an inner tubular member defining a lumen, an outer tubular member surrounding said inner member, and a support member mounted between the tubular members to provide rigidity to the flexible catheter. The support member comprises a high tensile strength wire braid, and in the preferred embodiment comprises a stainless steel wire braid which has been tempered or hardened. This higher tensile strength affords significantly greater kink resistance to the flexible catheter. One wire braid has a tensile strength in the range of 300 to 425 kpsi and a braid density of approximately 40 pic. The high tensile strength wire braid has the disadvantage of tending to flare out at its free ends. Therefore, means are provided for preventing the flaring of the wire braid during manufacture of the tubing assembly. One means includes adhesive applied over the free ends. Another means includes a restraining sleeve applied over the free ends.
