Patent CA-2158188-A1 (CA)
Inventor: KOCAN STEPHEN M
IPC: H04M7/00
Filed: 1995-09-13
Abstract: Increased network security is provided in accordance with the invention by usinginformation obtained from the signaling network to determine whether a call has been forwarded, and then using this information to make a determination as to appropriate further call processing, to minimize a communications company's exposure to callforwarding fraud. A determination of whether a call is a forwarded call can be made on the basis of a call forwarding indicator provided by another portion of the communications network. Where such an indicator is unavailable, a determination of whether a call is a forwarded call can be made by comparing the telephone number dialed to originate the call with the telephone number (the "connect number") associated with the telephone station to which the call has been forwarded. When the dialed number and the connect number differ, the call is determined to be a forwarded call.

Title: Pressure based calibration correction of an ion mobility spectrometer
Inventor: JACKSON RONALD A
IPC: H01J49/00
Filed: 1996-06-19
Abstract: The calibration of an ion mobility spectrometer is corrected for the actual operating pressure and temperature conditions within the system. An absolute pressure transducer is used to monitor absolute atmospheric pressure. This information is used in conjunction with the measured calibrant drift time to pre-determine expected drift times of target ions, compensating for any pressure and/or temperature differences from the reference conditions under which the original calibration has been carried out. This improved calibration allows the unit to be operated with a significantly lower waiting period after start-up, and also under significantly different atmospheric pressure conditions. It also improves the precision of operation of the system.

Title: System for preventing needle displacement in subcutaneous venous access ports
Inventor: WENNER DONALD E
IPC: A61M39/02
Filed: 1996-09-16
Abstract: A threaded, dual needle system is securely attached to a modified subcutaneous venous access port having an internal reservoir, used for intravenous drug therapy particularly in human cancer treatment. A hollow outer needle is paired with a removable, male-threaded solid inner point and inserted through the patient's tissue and through the port's protective, self-sealind silicon septum, and the solid inner needle is then removed, while the outer needle is left in place. Next, a hollow inner needle is threaded through the outer needle to a depth sufficient to interlock with a female-threaded port receptacle at the base of the port's fluidreservoir and rotated to install. Optional additional threading can permit securing the outer needle to the two inner needles. A breakaway system prevents displacement from unintented pulling of the flow-line. The system thus provides additional protection against needle displacement from venous access ports, the resulting leakage, and the problems caused thereby.
