Patent CA-2312036-A1 (CA)
Title: Device for controlling access to premises such as a water closet
Inventor: ROBAEY JACQUES
IPC: E03D11/00
Filed: 1998-12-04
Abstract: The automatic system encourages correct hand washing procedures, linking the operation of the tap and door lock. The system provides control of access to a toilet cabin which includes a hand washing basin (3). The hand basin includes a tap (4) and a sensor which detects whether the tap is turned on or not. There may also be a sensor using an electromagnetic signal to detect the presence of the hands under the jet of water. These sensors are used to control a device (100) associated with the door lock (10), such that the door is automatically locked when the hand basin is in use. The locking of the door may be effective for a certain minimum duration once use of the hand basin is detected. A manual over-ride control may also be provided.

Title: Method and corresponding apparatus for the production of honeycombs for beekeeping
Inventor: FERRER VIDAL CARLOS
IPC: B29C39/36
Filed: 2000-07-10
Abstract: The method consists in moulding both faces of the honeycomb simultaneously by the action of respective belts carrying cores having resilience properties and, after cooling of the honeycomb, subjecting it to compression on both faces to separate the cores from the walls of the cells. The apparatus comprises two endless belts which are arranged opposite one another and are mounted between respective pairs of guide drums and both of which are provided with resilient cores of a shape complementary to that of the cells to be produced, the last pair of drums being capable of exerting a compression force against both faces of the honeycomb produced in order to detach it from the cores.

Title: Method and apparatus for producing threshold arrays using variance minimization and pixel angle calculations
Inventor: PETERS MICHAEL ALAN
IPC: H04N1/405
Filed: 1998-10-01
Abstract: A method and apparatus for creating threshold arrays having a minimized gray scale variance without geometric artifacts. The invention comprises the steps of processing each candidate pixel in the threshold array using a variance minimization technique and applying a sparse image calculation on the same pixel. The preferred embodiment of the invention comprises the application of a variance minimization technique on a threshold array. The threshold array is analyzed on a pixel-by-pixel basis. Each candidate pixel that is to be turned on is examined in relation to the previous pixels that already exist. The candidate pixel is examined to determine its effect on the variance of the smoothed gray level determined by the convolution of the pixel pattern with a smoothing kernel. The candidate pixel is also examined in relation to the distribution of the angles it forms with the previously selected pixels. The preferred embodiment uses a variant of the combinatorial Hough transform.  In the preferred embodiment, there is an accumulator .array for each not yet selected pixel that has a location for each of a quantified set of angles. A sum is stored in this location based on those previously selected pixels which make an angle with the not yet selected pixel which is discretized to the angle corresponding to that location. The effect of the true angle may be distributed over more than one location of the accumulator array and may depend on distance and angle. It is desired that a pixel is selected which combines a low variance of the smoothed gray level with a favorable distribution of values in its angle accumulator array. This process is repeated until all the pixels in the threshold array have been selected.

IPC: H04W72/12
Filed: 1999-04-27
Abstract: In a cellular telecommunications system, a method of dynamically allocating packet data radio channels among users competing in a same cell for the channels involves determining a user ranking for each of plural competing users in the cell, and classifying each of the plural competing users into one of plural ranking classes. A number of the packet data radio channels available for each of the ranking classes is then determined, after which the users within each ranking class are sorted by ranking. The packet data radio channels are allocated to the users by sorted position within ranking classes.  The user ranking for each of the plural competing users in the cell is related to a weighted combination of plural measures of performance for the user.

Title: Method and apparatus for improving image quality in positron emission tomography
Inventor: STARK IAIN
IPC: G01T1/208
Filed: 2001-01-16
Abstract: A method and apparatus for improving the image quality of positron emission tomography is disclosed. This is achieved by analysing individual photomultiplier tubes for true events. The apparatus includes a photomultiplier tube for generating a photomultiplier tube signal. A series of pull up resistors generates a code signal identifying the photomultiplier tube. A clock generates a time stamp to the photomultiplier tube signal. A bus buffer generates an encoded signal. A position computing device calculates the position of the photomultiplier tube. An image computer generates an image from a plurality of encoded signals. A display displays the image. Analysing data from individual photomultiplier tubes results in smaller areas and smaller amounts of data to be processed. This then permits smaller time frame windows to be used. The use of time stamps also permits data before and after an event to be recorded.
