Patent CA-2272791-A1 (CA)
Title: Telecommunication module having edge mounted jack and switch therefor
Inventor: KUTSCH DUANE B
IPC: H04Q1/14
Filed: 1999-05-20
Abstract: A telecommunication module that has a circuit board disposed therein with a bounding edge. The module includes a jack coupled to the edge of the circuit board for receiving a plug therein with an active state and an inactive state. A switch is mounted on the circuit board and a switch operation shaft is mechanically and electrically coupled to the switch and extending outward therefrom such that the switch operation shaft is adjacent to the jack. When the plug is inserted into the jack, the switch operation shaft is rotated thereby changing states of the switch. An angled ramp is coupled to the switch operation shaft and spaced apart from the switch. The jack further includes an opening disposed therein for receiving the angled ramp therein. Moreover, when the plug is inserted into the jack, the plug contacts the angled ramp within the jack causing the switch operation shaft to rotate, thereby changing states of the switch as the angled ramp is biased from within the jack.

Patent CA-2277307-A1 (CA)
Inventor: MAGLIOCCA CHARLES THOMAS
IPC: B01D33/11
Filed: 1998-01-15
Abstract: A parts washing centrifugal filter (16) that substantially reduces the need to replace the solvent. The parts washing apparatus comprises a parts washing basin (12) that has a centrifugal assembly (16) located below its drain (18). The parts washing basin (12) sits on top of a solvent container (14). When in use, the solvent is pumped from the solvent container (14) to the parts washing basin (12), where it is used to clean parts. The now contaminated solvent flows down a drain (18) in the parts washing basin (12), through a screen (142) to the centrifugal assembly (16). A disposable filter (34) is included in the filter receptacle (32) of the centrifugal filter assembly (16). The contaminated solvent flows from the drain (18) into a disposable filter element (34) located in a spinning filter receptacle (32), where centrifugal force draws the solvent back into the solvent container (14) while the materials washed from the parts remain in the disposable filter element (34). If desired, separate filter assembly (148) can be used to polish the solvent. A "retrofit" application for mounting the centrifugal filter assembly (16) in existing parts washers is also described.

Title: A method and apparatus for segmenting images prior to coding
Inventor: CHEN TSUHAN
IPC: G06T7/20
Filed: 1998-01-20
Abstract: To segment moving foreground from background, where the moving foreground is of most interest to the viewer, this method uses three detection algorithms as the input to a neural network. The multiple cues used are focus, intensity, and motion. The neural network consists of a two-layered neural network. Focus and motion measurements are taken from high frequency data, edges; whereas, intensity measuremenets are taken from low frequency data, object interiors. Combined, these measurements are used to segment a complete object. Results indicate that moving foreground can be segmented from stationary foreground and moving or stationary background. The neural network segments the entire object, both interior and exterior, in this integrated approach. Results also demonstrate that combining cues allows flexibility in both type and complexity of scenes. Integration of cues improves accuracy in segmenting complex scenes containing both moving foreground and background. Good segmentation yields bit rate savings when coding the object of interest, also called the video object in MPEG4. This method combines simple measurements to increase segmentation robustness.

Title: Acquiring a spread spectrum signal
Inventor: FULTON FORREST F
IPC: H04B1/708
Filed: 1998-06-19
Abstract: A spread spectrum signal is detected at an unknown spreading signal phase by sampling the signal at a selected sampling rate (104) and performing a despreading function (114) on the sampled signal using multiple reference signals (116), each of which represents one of multiple search phases of the spreading signal. Accumulation outputs then are produced by combining each despreading output with a phase-shifted version of the corresponding accumulation output (114).

Abstract: Brake control apparatus is disclosed, the apparatus comprising: an electric motor arranged to drive a wheel; brake means operable to apply a braking force to inhibit the rotation of the wheel; input means operable to generate an input signal indicative of a desired angular velocity of the wheel; current monitoring means for generating a monitoring signal indicative of a current flowing through the electric motor; and control means, for controlling the supply of power to the electric motor in response to the input signal by generating a control voltage, and for controlling the brake means such that after setting the control voltage to zero the brake means apply the braking force at a braking time determined according to the monitoring signal. The braking time may be determined according to the magnitude of the monitoring signal when the control voltage is set to zero, according to the rate of change of the monitoring signal, or according to the polarity of the monitoring signal. An electric vehicle comprising the brake control apparutus is also described and claimed, as is a method of controlling brake means for applying a braking force to inhibit the rotation of a wheel driven by an electric motor.
Patent CA-2296049-A1 (CA)
Inventor: GAGNON ROBERT
IPC: C10G1/08
Filed: 2000-01-17
Abstract: Petrolisation relates to a method of producing crude petroleum from organic wastes. All kinds of organic wastes (for examples domestic wastes, vegetal residues, animal residues, residues from paper, wood, textile, plastic, rubber, even manure, rotting matters, used tires, etc.) can be thermolysed and hydrogenated using a combination of iron catalyst and a salt catalyst.  Shredded and dried organic wastes are thermolysed and hydrogenated at not very high temperatures and not very high operating pressures without a significant consumption of hydrogen. The process takes less than one hour and yields a mixture of liquids like crude petroleum. Unlike previous processes that need specific kind of homogeneous organic waste through specific process to specific fuel, petrolisation is a universal process that accepts all kinds of heterogeneous organic wastes and yields various hydrocarbons with commercial value.  Since crude petroleum is not renewable and not available everywhere, petrolisation solves these problems by using all kinds of renewable and everywhere available organic wastes as raw materials to make crude petroleum. The process yields five times more energy than it consumes, in other words, sufficient valuable crude to be a permanent source of crude petroleum. For example, one metric ton of organic wastes yields about 5 barrels of crude plus many other matters with commercial value. Moreover, this synthetic crude petroleum contains no sulphide. Petrolisation is also a profitable solution to organic waste disposal benefiting from recycling these useless wastes and eliminating the necessity of burning or destroying them in incinerators or dumps. Petrolisation is a self-sufficient process.

Title: Hypersensitive response elicitor from pseudomonas syringae and its use
Inventor: ALFANO JAMES R
IPC: A01N63/50
Filed: 1998-07-24
Abstract: The present invention is directed to an isolated protein or polypeptide which elicits a hypersensitive response in plants as well as an isolated DNA  molecule which encodes the hypersensitive response eliciting protein or polypeptide. This isolated protein or polypeptide and the isolated DNA  molecule can used to impart disease resistance to plants, to enhance plant growth, and/or to control insects on plants. This can be achieved by applying the hypersensitive response elicitor protein or polypeptide in a non-infectious form to plants or plant seeds under conditions effective to impart disease resistance, to enhance plant growth, and/or to control insects on plants or plants grown from the plant seeds. Alternatively, transgenic plants or plant seeds transformed with a DNA molecule encoding a hypersensitive response elicitor protein or polypeptide can be provided and the transgenic plants or plants resulting from the transgenic plant seeds are grown under conditions effective to impart disease resistance, to enhance plant growth, and/or to control insects on plants or plants grown from the plant seeds.
