Patent CA-2272917-A1 (CA)
Inventor: KITNEY RICHARD IAN
IPC: G01S7/52

Abstract: An ultrasound scanning technique for biological tissue examines the radio frequency signals derived from reflected ultrasonic energy to identify signal parameters indicative of particular tissue histology. Such identification is then used to produce a histological image of the biological tissue. The technique is particularly useful in the examination of blood vessels to identify different types of plaque within the vessel wall. Lipid plaques produce relatively low levels of reflection. Calcified plaques produce high levels of regular reflection. Fibrous plaques may be identified as a highly homogeneous thickened wall area that does not show the characteristics of a lipid plaque. A homogeneity value for the radio frequency signal is calculated for all areas not identified as lipid plaques or calcified plaques and then this homogeneity value is mapped to a colour that is displayed within the histological image.

Title: Modular wearable computer
Inventor: JENKINS MICHAEL D
IPC: G06F1/16
Filed: 1999-06-17
Abstract: This invention involves the use of a number of component-containing modules each assembled together to form a conventional computer except that the computer is body worn and has beat-controlling aspects. One of the heat-controlling aspects is at least one or preferably each side of the module has a heat-air vent as a component of its side. Another heat-controlling item is the selection of heat or non-heat conducting materials to construct the module sides. It is preferable that module sides adjacent a user's body be of a heat-insulating material.
Patent CA-2275120-A1 (CA)
Inventor: LEDUC PHILIP
IPC: A01C23/00
Filed: 1999-06-15
Abstract: An apparatus is used for distributing a slurry flow to plural feed conduits. It has particular application in the injection of swine manure into the soil as fertilizer. The apparatus includes a circular manifold with a central inlet for delivering slurry to the manifold and outlet ports spaced around the outer wall of the manifold for connection to the respective feed conduits. An impeller in the manifold has back swept impeller blades mounted for rotation so that the impeller blades sweep in sequence past the outlet ports. The impeller blades produce pressurized zones in front of them as they sweep in sequence past the outlet ports. This produces a pulsating flow in the feed conduits, ameliorating blockage problems with the conduits. The impeller also includes knives that rotate around the inside of the outer wall and anvils mounted on the outer wall so the knives will act with the anvils to sever trash in the slurry flow. The knives and the anvils are oppositely inclined to produce a shearing action. This cutting arrangement co-operates with the pulsing flow to clear trash that might otherwise build up and plug the ports. It also reduces the size of solids that are included in the slurry, so that they will pass more readily through the feed conduits and the delivery boots used for injecting the slurry into the soil. The impeller drive is preferably an hydraulic motor mounted on the manifold.

Abstract: A portable training device that permits a coach to continuously and rapidly extract badminton shuttlecocks for the purpose of setting-up (feeding) athletes or students to hit specific shots. This device also acts as a storage unit for shuttlecocks (70-shuttlecock capacity). It is filly adjustable to meet the height of the user and can be set-up for use within seconds. It is useful for the athlete to use on his or her own (i.e., practicing serving), by groups of athletes to practice specific strokes or skills and by the coach to correct stroke technique (with the use of repetition), to build up endurance, speed and power in strokes and or work on court movement or strategy (as in mufti-shuttlecock drills). The badminton training and storage device consists of a horizontal base with wheels, with a vertical large square hollow post attached to the base perpendicularly.  There is a vertical small square hollow post that telescopes from the large square hollow post, and has attached at the front of its top end a large hollow tube used to house 40 shuttlecocks prior to extraction. The large hollow tube can rotate 360 degrees about a horizontal axis and has a cap at one end and at the other end inserted into the tube is a formed finger-like extraction unit that permits the extraction of shuttlecocks with minimal force. There is a handle projecting upwards from the top of the small square hollow post that allows the user to tilt the unit backwards and roll the unit. Below the handle attached to the back of the large square hollow post is a removable small hollow tube that holds an additional 30 shuttlecocks that can be loaded into the large hollow tube.

Abstract: This application is directed to a linkage system which provides continuous rotation to two or more interconnected quadrilaterals. The basic element of the linkage system is a multi-level link which provides firstly, a non-rotatable connection between two sub-links lying in separate parallel planes and secondly, a rotatable connection for a further link lying in another parallel plane between the planes of the sub-links. By various interconnections between link elements, the quadrilaterals the linkage system will form various geometric patterns as the linkage is rotated. As the quadrilaterals lie in different planes, they may be continuously rotated with respect to each other. The linkage system may be used as a toy, a novelty item and as an educational tool.

Title: Selectively-activatible sheet material for dispensing and dispersing a substance onto a target surface
Inventor: TWEDDELL RICHARD III
IPC: A61K9/70
Filed: 1998-06-04
Abstract: The present invention provides a selectively-activatible sheet material for dispensing and dispersing a substance (16) onto a target surface (20). The sheet material comprises a three-dimensional sheet of material having a first side and a second side. The said first side has a plurality of hollow protrusions (14) extending outwardly therefrom and separated from one another by valleys, while the second side has a plurality of depressions corresponding with the hollow protrusions. A substance (16) adheres to and partially fills a location protected from external contact comprising the valleys and/or the depressions. The sheet material (10) may be selectively activated by deforming the hollow protrusions (14) to deliver the substance (16) to a target surface (20), the substance having an effective viscosity upon activation which permits the substance to be liberated from its protected location and dispensed onto the target surface. Suitable substances include cleansing agents, medicinal agents, emollients, lubricants, colorants, preservatives, protectants, condiments, adhesives, fragrances, anti-perspirants, deodorants, and combinations thereof. The present invention also includes such materials having two or more substances of diverse composition, and substances which undergo a decrease in effective viscosity upon activation (such as shear-thining substances) are particularly preferred. Additional layers of porous material may also be employed on the opposide side of the subtance from the sheet material such that the substance may be dispensed through the porous material. Porous materials may provide additional beneficial interaction with the subtance, including enhanced distribution and dispersal.

Abstract: The invention relates to a monitoring system for web breaks in a paper machine. A web (W) is monitored by means of a number of cameras (1) and the image data of various camera positions is used for compiling focused image regions (12). Camera-specific image processing equipment (2, 12) is adapted to compile image change data by comparing the change between sequential images as far as the focused image region (12) is concerned. The image change data is compared with a normal level of image change and an alarm message (3a) is delivered if the image change level has a deviation from the reference level which exceeds a preset threshold value. A break alarm is set off, in case said alarm message (3a) is delivered by image change data comparators (3) of one or more pre-selected camera positions (P1-Pn).
