Patent CA-2542267-A1 (CA)
Inventor: ROGERS STEVEN A
IPC: H04L12/407
Filed: 2004-09-22
Abstract: A method of transmitting packets over a network includes steps of partitioning a transmission interval into discrete time slots and reaching agreement between a transmitting node and receiving node as to when the transmitting node will transmit packets. The intended receiving node sends a reception map to the transmitter indicating time slots that have not yet been allocated. The transmitter proposes a delivery schedule including time slots that it will use for transmission. After agreement by the receiving node, the transmitter transmits packets according to the agreed-upon schedule. Other transmitters can similar arrange to transmit during time slots not already allocated for the receiving node.

Patent CA-2543141-A1 (CA)
Inventor: VIJAYAN RAJIV
IPC: H04H20/71
Filed: 2004-10-22
Abstract: Techniques to seamlessly switch reception between multimedia programs are described. For "continued decoding", a wireless device continues to receive, decode, decompress, and (optionally) display a current program, even after a new program has been selected, until overhead information needed to decode the new program is received. After receiving the overhead information, the wireless device decodes the new program but continues to decompress the current program. The wireless device decompresses the new program after decoding this program. For "early decoding", the wireless device receives a user input and identifies a program with potential for user selection. The identified program may be the one highlighted by the user input or a program anticipated to be selected based on the user input. The wireless device initiates decoding of the identified program, prior to its selection, so that the program can be decompressed and displayed earlier if it is subsequently selected.

Title: Ground stake
Inventor: WALKER SIMON
IPC: E04H15/62
Filed: 2006-04-11
Abstract: A ground stake for securing ropes or other fastening elements comprises a head portion with an elevated, textured surface and two or more extending flanges above a neck portion comprising recesses and a passageway. A plurality of elongated fins, at least a portion of which are tapered, depend from the base of the head portion and terminate in a truncated blunt end, providing a stronger tip while allowing clean penetration of the ground. One or more of the fins may comprise a stiffening rib to increase the rigidity of the fin. The elevated, textured surface provides increased impact resistance and prevents slippage of a pounding implement when the stake is being driven into the ground.

Abstract: A container and dispenser in conical shape for liquid or semi-liquid substances. The container features a rectangular rigid tab, two triangular notches on both sides of the tab at the height slightly below the tip of the cone, a perforated or indented scoreline to facilitate tearing off or cutting the top region of the tab, which is less rigid than the rest of the tab, where the top region of the container is made of a different material than the rest of the cone creating a zone of weakness at the indented dividing line between the top region and the rest of the cone and allows the user to easily tear off the top region of the tab and remove the top region of the cone opening a passageway in the tip of the cone where the substance can leave the dispenser by pressing the collapsible walls or back of the dispenser, without the need for a utensil.  Also, a yarn or thread may be attached to the tab along the scoreline of the tab and the dividing line of the cone to further facilitate the tearing off of the top region of the tab and the cone. In addition, the middle region of the cone is made in a foil-like material that makes the cone re-sealable by pressing the walls of the middle region against each other.

Patent CA-2554352-A1 (CA)
Inventor: MOHAMMADI FATEMEH
IPC: A61K35/74
Filed: 2005-01-25
Abstract: The present invention provides a method of activating a heat-activated component by an internal source of heat. As a result of an exothermic reaction between a combination of a heat-generating component and the heat-activated component, a source of heat is created within the composition without the use of an external heating source such as a hair dryer or exposure to the sun. The heat-generating component provides a heat release that triggers the activity of the heat-activated component. The compositions of the present invention are self-contained systems for generating heat to trigger the heat-activated component, and therefore, do not rely upon an external source of heat to affect the heat-activated component.

Patent CA-2561256-A1 (CA)
Inventor: CRAIG DAVID P
IPC: E21B49/00
Filed: 2005-02-17
Abstract: A refracture-candidate diagnostic test is an injection of compressible or slightly compressible fluid such as liquid, gas, or combination at pressures in excess of minimum in-situ stress and formation fracture pressure with pressure decline following injection test recorded to detect a fracture retaining residual width from previous stimulation treatments. The diagnostic consists of small volume injections with injection time being a small fraction of time required for compressible or slightly compressible reservoir fluid to exhibit pseudoradial flow. The fracture-injection portion of a test can be considered as occurring instantaneously, and the results obtained in an open infinite-conductivity hydraulic fracture with pressures above fracture closure stress during before-closure portion of pressure falloff and with pressures less than fracture closure stress during after-closure portion of pressure falloff. Data measurements are transformed into a constant rate equivalent pressure transformation to obtain adjusted pressures or adjusted pseudovariables which are analyzed to identify dual unit-slope before and after closure periods confirming a residual retaining width.
