Patent CA-2272944-A1 (CA)
Title: Polyurethane-peo-heparin coatings for medical devices
Inventor: PATNAIK BIRENDRA K
IPC: A61L29/08
Filed: 1997-11-18
Abstract: A bio-active coating composition is described which is the reaction product of two different reactions. The first reaction includes reacting a bio-compatible polymer backbone having .alpha.,.beta.-unsaturated carbonyl functionality with a hydrophilic spacer having at least one reactive functional group at its first and second ends. In this reaction, one of the reactive functional groups of the spacer reacts with a .beta.-carbon of the carbonyl functionality to bond the spacer to the polymer backbone. The second reaction includes reacting a bio-active agent with a remaining unreacted reactive functional group of the spacer in the presence of an optional catalyst to covalently bind the bio-active agent to the spacer.

Title: Apparatus and method for reducing spm/gvd in optical systems
Inventor: OTTOLENGHI PAOLO
IPC: H04B10/29
Filed: 1999-05-27
Abstract: An optical transmission system and method for reducing non-linear distortion caused by the interaction of Self Phase Modulation and Group Velocity Dispersion is disclosed. An optical link includes a transmitter for providing signals at a first optical wavelength, a transponder for converting the first optical wavelength to a second optical wavelength, a plurality of spans of optical transmission fiber and optical fiber amplifiers, a dispersion compensating device, and a receiver.  The system operates at a relatively high input power level. The transponder includes a device for smoothing edges of the rise and fall times of optical pulses, such as an electrical attenuator and low pass filter, so that sharp-edged pulses received from the transmitter are transformed to a Gaussian shape. A dispersion compensating device, such as an optical fiber grating, also helps to improve the bit error rate as a function of receiver sensitivity despite an overall link length less than 600 km.

Patent CA-2274689-A1 (CA)
Inventor: KANGAS KARI
IPC: H04M17/00
Filed: 1997-12-16
Abstract: The invention relates to a method for controlling a credit customer call.  Subscriber-specific accounts on which the subscribers can purchase connection time are kept at a centralized point of a telecommunications network. In order that tariff changes taking place on the connections may be observed in a simple way without causing a high instantaneous load on the network, a request (Initial_DP) requesting connection time for the use of the connection is sent to a centralized point (SCP) of the network. In response to the request, the balance of the account of said customer is checked at the centralized point of the network and the length of the connection time to be assigned to the connection per a request sent by the exchange is determined. When the balance of the account permits, a message (AC) including information (ST) on the length of the connection time assigned to the connection is sent in response to the request sent by the network exchange. During the connection, the network exchange monitors the elapsing of the connection time assigned per request, and when the assigned connection time is less than a specified threshold, an additional time request (ACR) requesting additional connection time is sent to the centralized point. Tariff changes are checked at least in connection with each discrete additional time request (ACR), and on the basis of the check, the length of the connection time to be assigned per a request sent by the exchange is redetermined, said message being retransmitted if the account balance permits. When the connection is terminated, the amount is adjusted in accordance with the actual moment of termination.

Title: Method for reducing deflagration of azinphos-methyl
Inventor: COHOON STEPHEN W
IPC: A01N57/16
Filed: 1999-08-31
Abstract: The present invention relates to a stable azinphos-methyl wettable powder formulation. The composition of the present invention contains an insecticide powder formulation and a magnesium sulfate heptahydrate.      The magnesium sulfate heptahydrate is added to the azinphos-methyl formulation in an amount such that the magnesium sulfate heptahydrate is from about 5% by weight to about 20% by weight of the total mixture.

Patent CA-2286869-A1 (CA)
Title: Block adaptive quantisation
Inventor: LANCASHIRE DAVID
IPC: H04N7/26
Filed: 1999-10-15
Abstract: A block adaptive quantisation device processes blocks of sample pairs to determine an aggregate or average value at 18. The average or aggregate value is applied to each of a number of exponent look-up tables 22 to 26, which output and exponent value (E) dependent on the extent of compression required. The exponent value is split by an exponent splitter into a remainder value (R) and a shift value (S). The remainder value is used to select one of a number of divide look-up tables to which the unsigned data sample is applied, and the shift value is used to apply a variable bit shift to the data sample (either before or after the division operation). Each divide look-up table 42 to 48 comprises the same group of divide look-up tables. The combination of the four look-up tables in the group, together with the variable bit shift defines a series of code tables made up of a group of divide look-up tables repeated at six dB intervals. The remainder value selects one of the code tables within the group, and the bit shift operation determines the selected one of the repeated groups. The code tables within the group are spaced logarithmically, as are the groups themselves. This arrangement considerably reduces the number of look-up tables required for a given processor, reducing memory requirement and increasing speed.

Title: System for measuring the effectiveness of internet based advertising or marketing campaigns
Inventor: ZENG MING
IPC: G06Q30/02
Filed: 2000-03-30
Abstract: A system for measuring the effectiveness of an Internet-based advertising campaign wherein e-mail messages are sent to recipients inviting them to visit a destination web site where further information is provided about the product/service being offered. The system incorporates an HTTP hypertext link in each e-mail which points to an intermediate web site and which includes information pertaining to the identity of the destination web site.  When the link is actuated or clicked through, the recipient's browser sends a web site request message including the identification information to a server hosting the intermediate web site.  The server consequently records the actuation of the link, thereby compiling statistics on the hit rate, and then redirects the recipient's browser to the destination web site.  Embodiments of the invention also track pass-alongs (i.e., where the original recipient passes a copy of the e-mail to a friend), and in the event the destination web site is an e-commerce site where the advertised product/service may be purchased, details of the purchase.
