Patent CA-2267755-A1 (CA)
Inventor: CAVE ELLIS K
IPC: H04M3/48
Filed: 1997-09-24
Abstract: A system and method for establishing a data connection between a computer and a live agent selected from an agent pool. A computer user uses the computer (100) to connect via a network (101, 102) with an information server (103).  While browsing information on the server, the customer can request to speak with an unspecified live agent. An agent queuing manager (11) receives the customer's request and selects an appropriate live agent from a pool of available agents (12A-C, 13A-C, 14A-C). Then, the agent queuing manager established a data connection between the live agent and the customer. The data connection is preferably an audio connection, although a real time text "chat" mode is also available. The agent queuing manager maintains the agent pool by monitoring when agents log in and out of agent terminals, as well as when the agents are engaged with a computer user.

Title: Method for solid phase polymerization
Inventor: RAMDAS DUJARI
IPC: C08G69/06
Filed: 1997-11-25
Abstract: An improved method for increasing the relative viscosity and molecular weight of a polyamide polymer (such as nylon 6,6, nylon 6, and the like) while in the solid state involving the use of a phosphorus-containing catalyst (such as 2(2'-pyrydyl)ethyl phosphonic acid, sodium hypophosphite, tolyl phosphinate and manganese hypophosphite or the like) in combination with an oxygen free gas characterized by a low dew point (typically below 30 °C and preferably below -30 °C). Operational and commercial advantages are derived from the combination of using simultaneously a phosphorus-containing catalyst and the recycle of very low dew point drying gas at lower operating temperatures than previously employed in conducting solid phase polymerization of polyamide polymer. Such a process is of particular value during the production of terpolyamide and multipolyamide polymer intended for use in colored nylon fiber manufacture.

Abstract: A tea infusing device comprises a cup body, a filtering net, a buckling disk, and a water stopping device. The water stopping device is received in the center through hole of the cup body, and is formed by a metal rolling ball and a soft water stopping pad, or a water stopping block and a rod. A filtering net is installed thereon. A circular protruding ring portion with a proper height extends downwards from the bottom of the cup body. The buckling disk has a rod at the center thereof and is movable upwards and downwards. When the tea infusing device is arranged on a plane, the buckling disk will drop down naturally so that the water stopping device will close a through hole. Thus, the tea can be soaked in the cup. However, when the tea infusing device is located at any proper container. The buckling disk will be ejected by the container so as to eject the water stopping device so that tea water may flow to the container successfully. The improvement of the present invention is that the outer diameter of the buckling disk is smaller than the inner diameter of the protruding ring portion so that it can be completely received in the inner space thereof and longitudinally moves therein. Thus, water will not drain out due to an error contact to the buckling disk.

Title: Inspiratory proportional pressure assist ventilation controlled by a diaphragm electromyographic signal
Inventor: FRIBERG SVEN
IPC: A61M16/00
Filed: 1997-07-17
Abstract: To control a lung ventilator (54) comprising an inspiratory implement (56) to be worn by the patient (14), an air supply system (55) for supplying air to the inspiratory implement (56), and a control unit (53) for controlling the air supply system (55), electromyographic signals (24, 25) produced by the patient's diaphragm (11) are detected by an array of electrodes (12) passing through the center of the patient's diaphragm depolarizing region (DDR).      The position of the center of the patient's diaphragm depolarizing region (DDR) is determined through detection of a reversal of polarity of the electromyographic component of the electrode-detected electromyographic signals (24, 25). First and second electromyographic signals (24, 25) detected by the electrodes of the array (12) on opposite sides of the patient's diaphragm depolarizing region (DDR) are subtracted from each other, this subtraction cancelling the noise components of the first and second electromyographic signals (24, 25) but adding the respective electromyographic components of these first and second signals (24, 25) together to produce an electromyographic signal (62) having an improved signal-to-noise ratio having a reduced electrode-position-induced filter effect and being representative of a demand to inspire from the patient's brain. The electromyographic signal (62) of improved signal-to-noise ratio is finally supplied as input signal to the control unit (53) of the lung ventilator (54) for controlling the air supply system (55) and therefore the inspiration assist in relation to the electromyographic signal of improved signal-to-noise ratio and of reduced electrode-position-induced filter effect, and therefore in relation to the demand to inspire from the patient's brain.

Title: Boundary sector hard handoff trigger
Inventor: JALALI AMHAD
IPC: H04W36/14
Filed: 1998-05-05
Abstract: A method and system for triggering hard handoff of a call from a CDMA network cell operating on a first frequency to a cell operating on at least one second frequency or in an AMPS network are disclosed. In a departure from the art, a boundary sector handoff trigger is implemented in two stages. The first stage of the trigger occurs when the active set of a mobile unit consists only of pilots identified as boundary pilots; that is, the active set comprises a "boundary active set." Once the requirements for the first stage are satisfied, a second stage of the boundary sector trigger of the present invention is enabled. During the second stage, a round-trip delay ("RTD") of communications between the mobile unit and the BTS to which it is nearest is monitored and once the RTD exceeds a predetermined threshold, the trigger is complete and handoff processing continues with target selection and handoff execution.

Title: Method and apparatus for polishing surgical stents
Inventor: FRANTZEN JOHN J
IPC: A61F2/82
Filed: 1998-06-05
Abstract: A method for polishing radially expandable surgical stents is disclosed where fluid abrasive media M flows over surfaces of the stent (10) causing the surfaces of the stent (10) to be polished and streamlined. The stent (10) is temporarily provided with cylindrical support ends (20), which are not radially expandable to support the stent (10) during the polishing process. An interior polishing fixture (100) is provided which has cylindrical chambers (135) therein adapted to receive a stent (10) therein. Fluid abrasive media M then flows into bores (108) in the fixture (100) leading to the cylindrical chambers (135) and adjacent the inner diameter surfaces of the stent (10). Surfaces of the stent (10) forming the outer diameter are polished by placing the stent (10) within an exterior polishing fixture (200) which has a cylindrical recess (220) therein. The cylindrical recess (220) has a diameter greater than a diameter of outer surfaces of the stent (10) and includes a cylindrical shaft (270) passing axially through the cylindrical recess (220) upon which the stent (10) is located. Slanted bores (208) pass through walls of the exterior polishing fixture (200) and into the cylindrical recess (220), directing the abrasive media M adjacent exterior surfaces of the stent (10) and causing polishing of the exterior surfaces of the stent (10). The direction of abrasive media M flow can be reversed to make streamlining of segments of the stent (10) occur in a symmetrical fashion. After polishing of the stent (10) is completed, the cylindrical support ends (20) are removed and the stent (10) is ready for implantation and radial expansion within a body lumen L. When polished and streamlined, the radially expandable surgical stent (10) more effectively supports a body lumen L without excessive thrombus, restenosis and other medical complications.

Title: Pacing output coupling capacitor for automatic capture threshold detection in cardiac pacing systems
Inventor: SPINELLI JULIO C
IPC: A61N1/365
Filed: 1999-06-01
Abstract: This invention is a method, and apparatus for attenuating polarization voltages or "afterpotentials" which develop at the heart tissue/electrode interface following the delivery of a pacing stimulus to the heart tissue such that the evoked response of the heart may be accurately detected to determine whether each pacing stimulus resulted in heart capture or contraction, thereby facilitating improved tracking of the capture threshold, and minimizing power consumption while assuring therapeutic efficacy. The conventional large capacitance coupling capacitor (96) used to suppress DC components of the pacing spike has another, much lower capacitance capacitor (94) connected in series with it. The lower capacitance capacitor (94) may be operable in either the auto-threshold mode or in the normal pacing mode such that its value can be selectively inserted in series with the larger capacitance coupling capacitor (96) to effectively lower the overall capacitance of the coupling capacitor following delivery of the pacing stimulus.
