IPC: H04L69/40
Filed: 2000-03-07
Abstract: A channel characteristic of a transmission channel (CHANNEL) between a remote terminal (RT) and a central office (CO) is estimated by collecting information in the remote terminal (RT), transferring this information from the remote terminal (RT) to the central office (CO) and matching the received information at the central office (CO) with a channel and remote terminal simulation model. The values of parameters of the latter simulation model, which define the channel characteristic to be estimated, are determined as a result of the matching process. The information collected by the remote terminal (RT) typically is information that is automatically collected by the remote terminal (RT) for operational purposes such as equaliser setting, bit allocation, and so on.

Title: Internet service provider call redirection
Inventor: MARCH SEAN
IPC: H04Q3/00
Filed: 2000-04-05
Abstract: A telephone network constructed according to the present invention includes call redirection functions that redirect calls intended for a toll-free-number or central number of an Internet Service Provider (ISP) to one of a plurality of available Internee Protocol (IP) gateways operated by the ISP. Call redirection may be performed within a coupled signaling network during a database lookup or Service Control Point operation, at a signal switching point of a destination switch or by a PBX operated by the ISP. The call redirection may be static or play be dynamic. In static call redirection, all calls are redirected to a single IP gateway. In dynamic call redirection, one of a plurality of available IP gateways is selected based upon operating conditions. In making such selection, IP gateway loading, IP gateway availability, telephone network loading, telephone network availability and telephone network routing costs are considered. In a first embodiment, a call is received by the telephone network and a number lookup is performed to identify the DN of the destination switch. The call is routed via the signaling network to the destination switch and redirected by the destination switch to a new IP gateway. The call is then completed to the new IP gateway. In a second embodiment, the call is first routed to a PBX operated by the ISP and the PBX redirects the call to a new IP gateway. In a third embodiment, the signaling network itself redirects the call to a new IP gateway.

Title: Methods and devices for the long-term culture of hematopoietic progenitor cells
Inventor: PYKETT MARK J
IPC: C12N5/10
Filed: 1998-09-25
Abstract: The invention pertains to methods and devices for the long term, in vitro culture of hematopoietic progenitor cells in the absence of exogenously added hematopoietic growth factors, improved methods for the introduction of foreign genetic material into cells of hematopoietic origin, and to apparatus for performing these methods. The hematopoietic progenitor cells are cultured on a three-dimensional porous biomaterial. The three-dimensional porous biomaterial enhances hematopoietic progenitor cell survival and leads to an expansion of progenitor cell numbers and/or functionality, while maintaining progenitor cell pluripotency in the absence of exogenous growth factors. In addition, the three-dimensional porous biomaterial supports high level transduction on cells cultured upon such environment.

Patent CA-2324096-A1 (CA)
Inventor: STAVE JAMES W
IPC: G01N33/543
Filed: 1999-03-05
Abstract: An assay device for the detection of analyte in a sample, methods and immunoassay formats for performing an assay with or without the device, and methods for manufacturing the device are provided. The device is a continuous liquid flow channel having a proximal and a distal end, with a detection membrane in fluid communication with the distal end of the flow channel.  Interspersed between the assay buffer and detection membrane, and continuous with the liquid flow channel, are a sample delivery means, one or more reservoirs containing the reagents necessary for conducting the assay, and, optionally, mixing or incubation reservoirs for combining the sample and reagents. The geometry of the liquid flow channel regulates the flow rate of the liquids through the channel, thereby controlling incubation, mixing and reaction time. The preferred detection membrane is an immunochromatographic test strip containing immobilized reagents. The detection of labeled reagent in a particular area of the detection membrane reflects the presence or relative amount of analyte in the sample. Detection may be achieved visually.  One or more liquid flow channels may be contained within a single housing for simultaneous, consecutive, or comparative sample analysis.

Filed: 2000-12-19
Abstract: An integrated optics chip (70) includes an optical waveguide network (11) formed on a surface (106) of a substrate (72) formed of an electrooptically active material. The optical waveguide network (11) has an input facet (86) where an optical signal may be input to the optical waveguide network (11) and an output facet (88) where optical signals may be output from the optical waveguide network (11). A trench (74) is formed in the bottom surface (80) of the substrate and arranged to extend into the substrate toward the optical waveguide network (11). The trench (74) prevents light rays incident thereon from inside the substrate (72) from propagating to the output facet (88). In particular, the trench (74) prevents light scattered at the input facet (86) or from scattering centers in the optical waveguide network (11) from reflecting from the bottom surface (80) of the substrate (72) to the output facet (88). A cover (78) may be mounted to the top surface (106) of the substrate (72) to provide structural strength to the integrated optics chip (70). One or more side grooves (143, 144) may be formed in the sides of the substrate (72) and cover (78). A light absorbing material may be placed in the trench (74) and grooves (143, 144).

Title: Stent deployment device and method for deploying a stent
Inventor: GEITZ KURT
IPC: A61F2/962
Filed: 1999-04-21
Abstract: A stent deployment device for deploying a stent within a body cavity comprises an endoscope having a protective cap, a flexible stent, a sheath, and a flexible, elongated member. The protective cap is mounted on the distal end of the endoscope providing a protected surface for retaining the stent. The flexible stent is circumferentially compressed over the perimeter of the cap, and the sheath is then releasably wrapped around the stent to hold it in a compressed configuration over the cap. The flexible, elongated member, such as a wire extending through a working channel of the endoscope, is attached to either the sheath directly or to a releasing device for the sheath. After the endoscopic device is inserted in a body cavity, the flexible, elongated member is pulled through the working channel to release the sheath and deploy the stent into a desired body opening in the body cavity. After deployment of the stent, the sheath can be left in the body cavity for subsequent retrieval or retracted through the endoscopic device.

Title: Dtv signal with gcr components in plural-data-segment frame headers and receiver apparatus for such signal
Inventor: LIMBERG ALLEN L
IPC: H04N5/21
Filed: 1999-05-11
Abstract: A DTV signal has a plural-data-segment frame header (figures 3A-3D) including complementary first and second ghost-cancellation reference signals (41 and 42) differentially delayed by the duration of two NTSC horizontal scan lines.  A receiver for such DTV signal has an adaptive equalizer (11) for baseband symbol code with kernel weights calculated by a computer (26) operative on the equalizer response after comb filtering. The comb filter (30) combines the equalizer response as differentially delayed by the duration of two NTSC  horizontal scan lines to cancel artifacts of co-channel NTSC interference in the comb filtering equalizer response supplied to the computer (26). This reduces the undesirable influence of such artifacts on equalization to reduce intersymbol interference.
