Title: Protecting therapeutic compositions from host-mediated inactivation
Inventor: SETHURAMAN NATARAJAN
IPC: A61K48/00
Filed: 2001-10-11
Abstract: The present invention relates to a method for determining the modification conditions of a therapeutic agent comprising (1) assaying the biological activity of a first modified therapeutic agent after the first modified therapeutic agent has been administered to a subject; (2) assaying the biological activity of the first modified therapeutic agent after at least one booster dose of the first modified therapeutic agent has been administered to said subject (3) carrying out (1) and (2) with an additional modified therapeutic agent that has been modified differently than the first modified therapeutic agent; and (4) comparing the biological activity of the first modified therapeutic agent with the biological activity of the additional modified therapeutic agent.

Patent CA-2425855-A1 (CA)
Title: A method of searching recorded digital video for areas of activity
Inventor: ORTH JEFFREY J
IPC: H04N5/77
Filed: 2001-06-28
Abstract: A method of scanning recorded video images of a scene to locate those images in which there is a predetermined amount of activity. Images (I) of the scene are obtained over a period of time. Each of the images (SI) is compared to a reference image (RI) of the scene and a difference image (DI) is created for each comparison. A threshold test is applied to each image as a measure of the activity occurring in the scene at the time the image is obtained and the results of the test are stored with the image in a memory (18) of an image processing system (10). When the images are subsequently viewed, a viewing threshold related to the amount of activity occurring in the scene is established by the viewer. The test results for each stored image are then scanned to determine if the image meets the viewing criteria. If it does, the image is either displayed for viewing on a monitor (24) or a file (F2) is created for analysis. Since the viewing threshold criteria can be rapidly determined for a large number of stored images, it is not necessary to view the images in their sequential order. This saves a substantial amount of time and allows the user to quickly locate pertinent information related to activities at a monitored site.
Patent CA-2426245-A1 (CA)
Inventor: NAGEL THOMAS O
IPC: A47F5/08
Filed: 2003-04-17
Abstract: A one-piece straight-entry display hook device is provided which is highly resistant to dislodgment resulting from upward pressure adjacent to the supporting panel, yet accommodates free upward pivoting movement in response to upward pressure on the hook applied at outer portions thereof. The display hook (10) has a specially configured back plate (12) with upwardly tilted mounting lugs (21) of inverted L-shaped configuration along upper edge portions thereof, and downwardly angled retaining elements (25) projecting from lower edge portions thereof. When the back plate is mounted on an apertured panel (13), upward movement of the back plate, which might otherwise dislodge the display hook and cause it and its contents to fall off the wall, is prevented by engagement of the retaining elements (25) with a pair of openings (30) in the panel board. If the hook receives upward pressure from a point spaced outwardly from the panel board, the hook is free to tilt upwardly in response, by pivoting about the upper mounting lugs (21), while the lower retaining elements (25) withdraw partially from the panel board openings (30) below. By upwardly tilting the mounting lugs at the top of the back plate, the back plate is allowed to tilt freely outward when necessary, if bumped near its outer end by store personnel or customers.

Patent CA-2450044-A1 (CA)
Title: Managed file system filter model and architecture
Inventor: CHRISTIANSEN NEAL
IPC: G06F9/44
Filed: 2003-11-18
Abstract: A model in which filter drivers are managed to receive callbacks for I/O requests in which the filter drivers have registered an interest. Per-volume instances of filter drivers register with a filter manager for pre-callbacks (for I/O to the file system) and post-callbacks (for I/O from the file system), and identify which I/O requests (e. g., create, read, write) they are registering to receive callbacks. The filter manager orders the instances for callbacks. When an I/O request is received, the filter manager converts the I/O request to callback data and calls the interested filters in the callback order, whereby the filter instances can process the I/O data. As the request returns from the file system, filters desiring post callbacks are called in the reverse order. Efficient context management for the filters and other functions, such as non-reentrant file I/O, are also provided by the model.

Patent CA-2461995-A1 (CA)
Inventor: GEORGI DANIEL T
IPC: G01V3/32
Filed: 2002-08-16
Abstract: Many reservoirs of interest include heavy oil. In such reservoirs, parti at normal temperatures, many instruments commonly used for formation evaluation may not be able to distinguish between heavy oil and bound water in the formation. Passive or active heating is used to elevate the temperature of the fluids in the formation. At elevated temperatures, distinguishing between heavy oil and bound water is easier. Of particular interest is the increase in the resolvability of the transverse relaxation time T2 of NMR spin echo measurements. Additionally, the dielectric constant and the loss tangents of water and heavy oil show different temperature and frequency dependence.
