Patent CA-2284662-A1 (CA)
Title: Method and system for processing supplementary product sales at a point-of-sale terminal
Inventor: ALDERUCCI DEAN A
IPC: G06Q20/00
Filed: 1998-03-20
Abstract: A POS terminal determines an upsell to offer in exchange for the change due to a customer in connection with a purchase. The point-of-sale terminal preferably maintains a database of at least one upsell price and a corresponding upsell to offer a customer in exchange for the change due to him. If the customer accepts the upsell, the cashier so indicates by pressing a selection button on the POS terminal. The required payment amount for the customer to pay is then set equal to the rounded price, rather than the purchase price. Thus, the customer receives the upsell in exchange for the coins due to him, and the coins need not be exchanged between the customer and the POS terminal.

Title: Procede permettant de disposer un condensateur enterre et condensateur enterre dispose selon ledit procede
Inventor: LARSSON TORBJOERN
IPC: H01L27/04
Filed: 1998-06-04
Abstract: L'invention concerne un procédé permettant de disposer un condensateur enterré sur un substrat ou support analogue et un condensateur enterré disposé selon ce procédé. Afin de diminuer les pertes par résistance dans un condensateur et afin de le rendre plus efficace, on peut utiliser dans des circuits à semi-conducteurs un ou plusieurs corps (14) métalliques tels que l'aluminium ou le tungstène à la place de la couche polycristalline. Ceci a pu être réalisé grâce à une nouvelle technique consistant à attaquer le remplissage de la tranchée formé d'un matériau conducteur sans que l'on ait à effectuer une extraction par attaque de la couche isolante (13) se trouvant dans la tranchée. Après avoir enlevé par attaque le remplissage de la tranchée, la tranchée est remplie au moyen du métal (14) précité, la couche isolante (13) située entre le matériau conducteur et le corps métallique sépare ainsi deux surfaces conductrices et l'on obtient un condensateur enterré.
Patent CA-2293164-A1 (CA)
Title: Mortise latch and vertical rod exit device
Inventor: PICARD DANIEL J
IPC: E05C7/06
Filed: 1999-12-29
Abstract: A mortise latch and vertical rod exit device latches at a center point between two doors and at top points between each door and the door frame. Optionally vertical rods may also be used to latch at bottom points between the doors and the floor. The latch includes an active and a passive latch mechanism operated by corresponding operating mechanisms. The mortise latch mechanisms cooperatively interact so that either door may be opened first, and either door may be closed first, without regard to the position of the other door. The active mortise latch mechanism includes a latch bolt and an activation bolt arranged so that one bolt is retracted when the other is extended, except when the doors are being opened or closed, when both bolts are retracted. The active mortise latch mechanism automatically retracts the latch bolt when the doors are not aligned and automatically extends the latch bolt when the doors are aligned. The passive mortise latch mechanism ejects the latch bolt as needed to allow the passive door to be opened first.

Patent CA-2308794-A1 (CA)
Title: Tin-bearing free-machining steel
Inventor: GARCIA C ISAAC
IPC: C21D6/02
Filed: 1998-11-16
Abstract: The invention relates to free-machining steels which do not rely on lead as a means of enhancing machinability. Instead, the steels of the invention employ concentrations of tin at ferrite grain boundaries to replicate a role of lead, which the inventors have discovered, in enhancing machinability. This role is to cause an embrittlement at the localized cutting zone temperatures by changing the fracture mode from transgranular to intergranular at those temperatures. The invention's use of concentrations of tin at ferrite grain boundaries of the steel permits the machinability-enhancing effect to be obtained while employing bulk tin contents below levels at which hot tearing becomes problematic. The invention improves over lead-bearing, free-machining steels in that the machinability-enhancing embrittlement produced by concentrating tin at ferrite grain boundaries is both controllable and reversible. The invention also relates to methods of producing the described tin-bearing, free-machining steels and the products of those processes.

Patent CA-2318284-A1 (CA)
Inventor: GOLDENBERG DAVID M
IPC: A61K47/48
Filed: 1999-01-14
Abstract: A method for intracellular delivery of drugs or other agents for diagnosis and therapy of malignancies or immune-mediated or inflammatory conditions. A  targeting moiety of an antibody and the ligand-binding region of a selected cytokine receptor is used. The targeting moiety targets surface antigen on a specific cell population. The targeting moiety is administered to a subject, and then, after a specified interval, therapeutic or diagnostic agents linked to the cognate cytokine are given. The invention provides rapid, efficient internalization of the cytokine receptor antibody/antigen complexes. Targeting of a high-level cell surface antigen with such bispecific fusion molecules substantially increases the number of cytokine receptors over their low background level.
Patent CA-2319480-A1 (CA)
Title: Method and apparatus for non-invasive blood constituent monitoring
Inventor: MILLER DAVID R
IPC: A61B5/00
Filed: 1999-02-05
Abstract: This invention is a system for determining a biologic constituent including hematocrit trans-cutaneously, non-invasive, and continuously.      A finger clip assembly (6) includes at least a pair of emitters, and a photo-diode in appropriate alignment to enable operation in either a transmissive mode or a reflectance mode. At least one predetermined wavelength of light is passed into or through body tissues (7) such as a finger, earlobe, or scalp, etc., and attenuation of light at that wavelength is detected. Likewise, the change in blood flow is determined by various techniques including optical, pressure, piezo and strain gage methods.      Mathematical manipulation of the detected values compensates for the effects of body tissue, fluid, and determines the hematocrit value. If an additional wavelength of light is used which attenuates light substantially differently by oxyhemoglobin, and reduced hemoglobin, then the blood oxygen saturation value, independent of hematocrit may be determined. Further, if an additional wavelength of light is used which greatly attenuates light due to bilirubin (440 nm) or glucose (1060 nm), then the bilirubin or glucose value may also be determined.      Also, determination of the hematocrit with a two step DC analysis technique is disclosed.

Title: Apparatus and method for packet-based media communications
Inventor: SIMARD FREDERIC F
IPC: H04M3/56
Filed: 2000-09-14
Abstract: Packet-based central conference bridges, packet-based network interfaces and packet-based terminals are used for voice communications over a packet-based network.      Modifications to these apparatuses can reduce the latency and the signal processing requirements while increasing the signal quality within a voice conference as well as point-to-point communications. For instance, by selecting the talkers prior to the decompression of the voice signals, decreases in the latency and increases in signal quality within the voice conference can result due to a possible removal of the decompression and subsequent compression operations in a conference bridge unnecessary in some circumstances. Further, the removal of the jitter buffers within the conference bridges and the moving of the mixing operation to the individual terminals and/or network interfaces are modifications that can cause lower latency and transcoding within the voice conference.

Patent CA-2326753-A1 (CA)
Inventor: FOKINE MICHAEL
IPC: C03C25/00
Filed: 1999-04-01
Abstract: In an optical fiber or other light guiding body is utilized that the diffusion properties of fluorine, which reduces the refractive index, are strongly changed, if also a doping with phosphorous is made, to change the refractive index and thereby the light guiding properties. In for example a single mode fiber (1) thus locally an additional waveguide core (9) can be created parallel to the already existing waveguide core (3), by providing in parallel to the ordinary core (3) an activatable region (5) having substantially the same dimensions as the existing core and having suitable dopings of fluorine and phosphorous. This can be utilized to produce an optical filter element. If the optical fiber is D-fiber, a sensor element can be produced. Furthermore, for suitable concentrations of these dopants and of germanium an existing waveguide core can be erased by a heating operation.
