Title: A predictive image caching algorithm
Inventor: DOBROTESCU VLAD
IPC: G06T1/60
Filed: 2001-05-29
Granted: 2005-02-15
Abstract: Methods of caching tile image constituents of image-mosaics enable a substantially smooth real-time display of portions of the image-mosaic in a view during panning, re-sizing, or zooming of the view. The method includes using a predictive algorithm to identify tile images to be retrieved from a remote store through a local area network, and for sequencing requests for the retrieval of tile images from the remote store. A scheduler calculates time spent in retrieving and servicing each tile image retrieval request and proportionately pauses retrieval of tile images after each request is serviced in order to prevent over utilizing LAN resources. The advantages are that tile images to be displayed are cached in accordance with a priority to facilitate image display while network data transfers are distributed in time.

Title: A self-contained, automatic mechanically opening and closing steam head with built-in thermostat
Inventor: ALTMAN MITCHELL
IPC: B05B1/00
Filed: 2002-01-04
Granted: 2007-10-30
Abstract: A self-contained thermo-mechanically self-opening steam head that is normally generally flush with a supporting steam room wall when not in use so as not to pose a safety hazard. The steam head has a mechanical thermostat that automatically responds to the presence of heat as from steam to move a deflector plate, which normally generally blocks a steam outlet from the head, to an open position. That open position is spaced from but closely in front of the steam outlet. This allows steam to flow out of the outlet, but the deflector plate diverts the outward steam flow to a direction generally along the supporting wall. When the steam is shut off, the thermostat cools and thereby causes the deflector plate to return to its closed, blocking position. There is no electrical wiring or connection which could pose a major safety hazard in the presence of water.

Patent CA-2379810-C (CA)

IPC: B09B1/00
Filed: 2000-07-13
Granted: 2008-07-08
Abstract: The phosphate mineral based reactive barrier prevents release of contaminants from waste via reaction with contaminants at the interface between the barrier and the waste. The barrier is comprised of a phosphate mineral material that is primarily insoluble. The barrier is placed below, around, and/or on top of contaminated materials such that they are completely contained by a grout curtain. The barrier can be a slurry, blended matrix with other inorganic agents, or composite with a geotextile or geofabric.  These methods of construction are used singly or jointly. pH control may be used to optimize chemical reactions within the barrier.  The mechanism relies on the phenomena of adsorption, surface precipitation and co-precipitation of metal phosphate surface precipitates to chemically retard diffusion from the waste. Immobilization may occur secondarily when a small percentage of the phosphate minerals partially dissolve and the phosphate precipitates with metals to form metal phosphate precipitates.

Title: Visual attention system
Inventor: STENTIFORD FREDERICK WARWICK M
IPC: G06T9/00
Filed: 2001-02-08
Granted: 2008-02-19
Abstract: This invention identifies the most significant features in visual scenes, without prior training, by measuring the difficulty in finding similarities between neighbourhoods in the scene. Pixels in an area that is similar to much of the rest of the scene score low measures of visual attention. On the other hand a region that possesses many dissimilarities with other parts of the image will attract a high measure of visual attention. The invention makes use of a trial and error process to find dissimilarities between parts of the image and does not require prior knowledge of the nature of the anomalies that may be present. The method avoids the use of processing dependencies between pixels and is capable of a straightforward parallel implementation for each pixel.  The invention is of wide application in searching for anomalous patterns in health screening, quality control processes and in analysis of visual ergonomics for assessing the visibility of signs and advertisements. The invention provides a measure of significant features to an image processor in order to provide variable rate image compression.

Abstract: A communications network has a plurality of nodes interconnected by an optical transmission medium. The transmission medium is capable of a carrying a plurality of wavelengths organized into bands. A filter at each node for drops a band associated therewith and passively forwards other bands through the transmission medium. A device is provided at each node for adding a band to the transmission medium. Communication can be established directly between a pair of nodes in the network sharing a common band without the active intervention of any intervening node. This allows the network to be protocol independent. Also, the low losses incurred by the passive filters permit relatively long path lengths without optical amplification.
