Patent CA-2285527-A1 (CA)
Inventor: YOUNG RONALD SCOT
IPC: A47L13/58
Filed: 1999-10-07
Abstract: A removable and replaceable filter and filter holder is mounted within a mop cleaning bucket to receive dirt settling under gravity from the contained liquid with the dirt collecting in, and passing through so as to be trapped below, the filter and its holder.  The holder is a rigid or substantially rigid perforated support structure spaced above and below the dirt receiving filter. In one embodiment, the holder is supported in the bucket in spaced relationship to the bottom of the bucket and protects the filter. The filter is a thin, sturdy, semi-rigid and floatable member with many holes so soiled water passes through and collects in the bottom of the bucket. The construction of the filter can be selected depending upon the material (grease sludge, dirt, oil, soot, or food particles) to be mopped up. The combination of the filter and filter holder blocks or dampens turbulence and prevents sediment from being stirred up in the bottom portion of the bucket. In the absence of the present invention, sediment could rise upwardly and mix with cleaner water above the filter and filter holder and which is reserved for mop cleaning and rinsing.

Inventor: SANO MITSUHIRO
IPC: H02K7/14
Filed: 1999-04-06
Abstract: A driven body displacement sensor comprising a brushless motor, capable of simplifying the structure of a flow control valve for controlling the flow rate of, for example, cooling water driven by a brushless motor, and of being miniaturized and reduced in cost. The opening of a flow control valve (11) for controlling the flow rate of cooling water fed to the radiator side is controlled by a brushless motor (11). A rectifying switch signal for driving the brushless motor (11) is received by a phase sequence detecting circuit (22a) to control an up-down counter (22b). A calculating circuit (22c) calculates the count of the counter (22b) and hence the opening of the flow control valve (11) can be grasped. The opening is fed back to an ECU to perform calculation with respect to the opening and other operation parameters, thereby realizing an ideal controller for controlling the cooling of an engine.

Patent CA-2293221-A1 (CA)
Inventor: WEBB JAMES R
IPC: H04N3/233
Filed: 1998-06-15
Abstract: A high-speed approximation device that generates zone correction values in both the horizontal and vertical directions. Group correction values are stored for specific physical locations on the screen (12, Fig. 1 & 2) for each correction factor parameter. Higher resulotion correction signals can be produced by generating zone correction values. Zone correction values are produced for binary fractional addresses that correspond to specific physical locations on the screen. By addressing specific binary fractional addresses that correspond to the location of the video image on the screen, new group correction values do not have to be produced each time the horizontal or vertical size or centering or frequency of the video image is changed.  Additionally, by using start addresses (32 Fig. 4 & 72 Fig. 6) and end addresses (34 Fig. 4 & 74 Fig. 6), zone correction values only have to be produced for the area which the video image occupies on the screen. The present invention also uses a high-speed binary fractional multiplier that multiplies a correction value by a series of binary numbers that simply shift the decimal location of the correction value to produce quotient values.  Selection of the quotient values is made by a binary fractional address signal that indicates the specific address for the zone correction value to be generated. By transforming from an arbitrary line count address space to a binary physical address space, the present invention allows for the use of a simple and fast parallel binary fractional multiplier engine.

Abstract: A self-contained tire-manufacturing cell (100) has linked build cure, and force-measurement equipment. Each tire is tagged (personalized), such as with a bar code, so that it can be traced through the system, including which one of a number of build drums it was built upon, which one of a number of mold cavities it was cured in and which one of a number of force variation testing machines it was tested on. The system performs force measurements upon each tire after curing, in near real time after the tire is produced, and displays this information in a graphical symbolic format (300), from which process variations can readily be ascertained by the operator. In an exemplary embodiment, the force measurements are presented to the operator in the form of a polar plot (300), each circular band or ring of which is associated with an individual tire. The visual appearance of the band varies in shading, color, or the like, as a function of force-measurement date at various circumferential positions on the tire, each distinct shading, coloring, or the like representing a predetermined range of data (i.e., within a first range, within a second range, within a third range, etc.).

Title: A heuristic method for adaptive subdivision of coons patches for rendering
Inventor: HOUTMAN REYNOLD
IPC: G06T17/20
Filed: 2000-04-11
Abstract: The invention discloses a method for preparing Coons patches for rendering. The Coons patch is examined for folds and any regions containing folds are isolated from regions that do not contain folds. The rendering method appropriate for fold containing and non-fold containing regions can then be selected. The rendering method appropriate for fold containing regions requires extensive computation compared to that for non-fold containing regions. By isolating the regions containing folds, the invention allows the avoidance of the extensive computation for the non-fold containing regions. Thus, the invention enables reduction of the amount of computation that is required during rendering.

Abstract: A system providing access to web objects that matches predicted demand for web objects to available capacity on web servers. The system implements methods to dynamically shape both demand and capacity based on certain criteria. The system provides methods to dynamically shape demand for an object based on criteria such as arrival time, incoming geography, and costs requirements. In particular, the present invention characterizes future demand for an object based on aggregation and forecasting of past demand for such object. The system effectively permits control and customization of capacity across one or more media servers based on characteristics associated with the demand across one or more of them, and particularly, based on the dominating geographical traits of past demand.  Moreover, the system dynamically shapes capacity by: (a) controlling the number of replicas associated with an object; and, (b) controlling the placement of these replicas across servers in a distributed network. In particular, the system drives capacity shaping measures over a particular object based on its predicted demand. Consequently, the number and location of replicas associated with an object is made to be variable over time and driven by predicted demand for a web object.
