Patent CA-2414636-A1 (CA)
Title: Method of capturing constant echo path information in a full duplex speakerphone
Inventor: BEAUCOUP FRANCK
IPC: H04M9/08
Filed: 2002-12-18
Abstract: A method of improving convergence of an echo canceller in a full duplex speakerphone, wherein the echo canceller includes LEC (Line Echo Canceller) and AEC (Acoustic Echo Canceller) portions, comprising the steps of capturing coefficients during operation, storing the coefficients, and utilizing the stored coefficients as default values during start-up of a subsequent call. According to the method of the present invention, the amount of echo cancellation necessary to provoke a save of the coefficients decreases with time when it is not achieved by the system despite the presence of a reference signal (i.e. speakerphone signal).

Title: Device for producing an aqueous chlorine dioxide solution
Inventor: GIRARD J BLAIR
IPC: A61L2/18
Filed: 2001-06-26
Abstract: A device (20) for producing an aqueous chlorine dioxine solution when placed in water. The device includes a membrane shell (22) that defines a compartment (30) which includes one or more dry chemicals (e.g., a metal chlorite (32) and an acid)(34) capable of producing chlorine dioxide gas when exposed to water.  Wick means extend into the compartment (30)for absorbing water and transporting water into the compartment (30) such that the chemical(s) in the compartment (30) dissolve in the water and produce chlorine dioxide. In one embodiment, the membrane shell (22) is formed of a material that allows the passage of gas (e.g., chlorine dioxide) but is impervious to liquid. In another embodiment, the wick means is a wick member (22) which divides the compartment (30) into first and second compartment sections. One chemical is contained within the first compartment section and another chemical is contained within the second compartment section. When the device (20) is placed in water, water enters the device (20) by way of the wick means. The chemicals dissolve in the water and react to produce chlorine dioxide gas. The chlorine dioxide gas then passes through the membrane shell (22) into the surrounding water transforming the water into an aqueous chlorine dioxide solution.

Title: Method for the production of biodegradable foamed products
Inventor: ERRINGTON JOHN GOUGH
IPC: B29C44/34
Filed: 2001-04-06
Abstract: A method for the production of a biodegradable foamed product 7 from a base material and a blowing agent 1. The base materials are mixed with a blowing agent and any other required additives 1. The mixture 3, after extrusion 2, is placed in a microwave transparent mould 6 and processed in a microwave via distinct steps. The first step preheats the extrudate to a temperature just below the flash point 6. The second step 7 rapidly heats the extrudate beyond the flash point causing the extrudate to foam in the mould 7. By utilising this method it is possible to produce shaped articles with uniform properties and with packaging properties such as compressibility, resilience and shock absorption.

Title: Shock absorbing structures
Inventor: EDWARDS MARK STEPHEN
IPC: F16F1/06
Filed: 2002-01-22
Abstract: A shock absorbing structure includes a body defined by a plurality of adjacent coils. The coils are resilient and flexible when exposed to a load applied substantially off-axis, or perpendicular to the axis of the body. In use, the body is positioned so that the coils deflect in directions substantially normal to the axis of the body. In this way, the body acts like a shock absorber, but unlike a coil spring, the shock is absorbed by the laterally inward or outward flexing of the coils, rather than the extension or compression of the coils themselves along their axis. The body can be formed by coiling a monofilament strand which is made of a polymeric material, such as nylon. Any number and types of articles can be made by incorporating the shock absorbing structures of the present invention, including, for example, articles of footwear, impact resistant bumpers, tires, and vibration dampening pads.
