Inventor: SUZUKI AKIRA
IPC: H04W52/02
Filed: 1994-07-08
Abstract: A valid bit generator of a base station generates a valid bit to be disposed at or near the top of a message to be transmitted, sets the valid bit to be inactive if the message can be ignored, sets the valid bit to be active if the message cannot be ignored, and transmits the message. Upon reception of this message, a valid bit detector of each terminal station judges whether the valid bit added at or near the top of the received message is inactive or active. If inactive, a message analyzing process is immediately stopped, whereas if active, the message is received and analyzed to the end thereof.
Patent CA-2128125-A1 (CA)
Inventor: MANSOUR YAKOUT
IPC: H02J3/24
Filed: 1994-07-15
Abstract: In the past, in electrical power networks, the effects on the system of particular contingencies, such as interruption of a power line, have been modelled off-line. Such models have generally been overly conservative, adding considerable cost to power systems. The present invention provides an on-line method of transient stability assessment referred to as the "second kick" method. It does this by providing a computer model of the system, simulating a study contingency, measuring the effect on the energy properties in the system of the study contingency, and if instability is indicated, calculating the transient energy margin from the corrected kinetic energy and, if the measured energy properties indicate stability introducing an artificial contingency into the model which is of sufficient duration to make this system unstable and measuring the transient energy margin as the difference between the corrected kinetic energy after the artificial contingency and the minimum value of the corrected kinetic energy after the artificial contingency, after compensating for the potential energy change introduced into the system by the artificial contingency.

Patent CA-2135143-A1 (CA)
Title: Catheter joint with restraining device
Inventor: BERG TODD A
IPC: A61M25/00
Filed: 1994-11-04
Abstract: An intravascular 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 wire braid, and in the preferred embodiment comprises a stainless steel wire braid which has been tempered or hardened to give it a significantly high tensile strength. This higher tensile strength affords significantly greater kink resistance to the flexible catheter as the lumen size is increased and the wall thickness is decreased, however, the high tensile strength wire braid has the disadvantage of tending to flare out during a bonding process when the catheter is joined to a tip, for example. In this invention, a retaining device is added to the end of the catheter to be joined, for preventing the flaring of the wire braid, whether the wire be of a high tensile strength or not.

Title: Revertive calling automatic call distributor
Inventor: KAPLAN MARC P
IPC: H04Q3/00
Filed: 1994-11-16
Abstract: A cooperative network/premises-based automatic call distributor system and method is provided which minimizes networking costs  associated with distributing calls  to telemarketing agents in multiple locations, minimizes delays in providing desired services to callers, and improves the efficiency of telemarketing agents.  A call directed to a telemarketing complex arrives at the network.  The caller automatic number identification (ANI) and an identifying tag are forwarded via a data connection to a telemarketing agent management system which identifies an available and desired agent to service the call,  and launches a call to the network location associated with the original caller, thus completing  the  connection.    The  telemarketing  agent management system selects an appropriate agent based on data received  from  the  telemarketing  complex  and  from  the network.  Interactive queuing may also be performed by the network to provide additional information to assist call distribution and telemarketing agent response.  In a further embodiment, the telemarketing agent management system may retrieve caller profile information while the revertive call is launched to the network location associated with the caller.     In  addition,   telemarketing  agents  may  be strategically assigned a priori to network switch locations resulting in superior call setup characteristics for certain calls.

Title: Uses of nucleic acid analogues in the inhibition of nucleic acid amplification
Inventor: BUCHARDT OLE
IPC: C12Q1/68
Filed: 1993-06-07
Abstract: Nucleic acid analogues of the kind described in PCT/EP92/01220 (PNA's) which hybridise strongly to nucleic acids are used to inhibit nucleic acid amplification procedures such as PCR. False positives in subsequent PCR assays are prevented by hybridising a PNA to PCR amplification products. Assays capable of discriminating between single base pair mutants are con-ducted by using a PNA hybridising to one of the two allelic forms to inhibit a PCR amplification of that form selectively. Asym-metric PCR amplifications are carried out by starting a PCR symmetricaly using like quantities of forward and reverse primers and once the amplification is established disabling one primer by hybridising a PNA thereto.
