Patent CA-2256203-A1 (CA)
Title: A method for determining computer network topologies
Inventor: DAWES NICHOLAS W
IPC: H04L12/56
Filed: 1998-12-16
Abstract: The topology of a computer network including data-relay devices and node devices is determined, based on comparing the source addresses heard by the various data-relay devices. A source address table is compiled for each port of each data-relay device. Such ports are then classified as up or down. Up ports connect directly or indirectly to other data-relay devices which report source address tables while down ports do not. Up ports can be recognised since their source address tables intersect the tables on two or more ports on a single other data-relay device. Moreover, source addresses in the tables of down ports are not duplicated in the table of any other 'down' port but are duplicated in the tables of up ports that directly or indirectly connect to the data-relay device that contains that down port. After classification as down or up, each source address in each up port table is replaced by the source address of the data-relay devices containing the down port whose table contains that source address. The up port tables now contain only data-relay addresses and the addresses of non table reporting devices indirectly connected to up ports. The tables of pairs of 'up' ports are compared by intersection and the minimal intersection defines the most probable connection for each up port. The source addresses of devices in the table of a down ports are directly or indirectly connected to that 'down' port. The method can be applied repeatedly and the probabilities aggregated to provide arbitrary accuracy. A variety of methods are used to remove invalid source addresses and the addresses of devices that have moved during the collection of the source address tables.

Title: Apparatus and methods for the harmonic enhancement of electronic audio signals
Inventor: GARCIA ARTURO H
IPC: H04S1/00
Filed: 1997-08-12
Abstract: The present invention is a method and apparatus for simply and inexpensively enhancing an electronic audio signal in such a way that the quality of audible sound produced from the audio signal more closely approaches that of the original sound heard live in an acoustically designed environment. The present invention restores the perception of harmonics that are normally missing in an electronic audio signal. The apparatus includes a circuit (8) that causes an input audio signal to be distorted such that an enhanced audio signal (31) is produced that exhibits an improved harmonic quality compared to that of the original input audio signal. This distortion is a non-linear amplification (33) of enhancing harmonics or frequencies in the input audio signal. That is, a band of desirable harmonics or frequencies in the input audio signal are non-uniformly amplified across the band.

Patent CA-2269806-A1 (CA)
Title: Embedding and encapsulation of controlled release particles
Inventor: VAN LENGERICH BERNHARD H
IPC: B29C48/05
Filed: 1997-10-27
Abstract: Controlled release, discrete, solid particles which contain an encapsulated and/or embedded component such as a heat sensitive or readily oxidizable pharmaceutically, biologically, or nutritionally active component are continuously produced without substantial destruction of the matrix material or encapsulant. A release-rate controlling component is incorporated into the matrix to control the rate of release of the encapsulant from the particles. The additional component may be a hydrophobic component or a high water binding capacity component for extending the release time. The plasticizable matrix material, such as starch, is admixed with at least one plasticizer, such as water, and at least one release-rate controlling component under low shear mixing conditions to plasticize the plasticizable material without substantially destroying the at least one plasticizable material and to obtain a substantially homogeneous plasticized mass. The plasticizer content is substantially reduced and the temperature of the plasticized mass is substantially reduced prior to admixing the plasticized mass with the encapsulant to avoid substantial destruction of the encapsulant and to obtain a formable, extrudable mixture. The mixture is extruded though a die without substantial or essentially no expansion and cut into discrete, relatively dense particles. Release properties may also be controlled by precoating the encapsulant and/or coating the extruded particles with a film-forming component.
