Patent CA-2525658-A1 (CA)
Inventor: GIAN MICHAEL
IPC: G05D11/02
Filed: 1996-07-25
Abstract: A system for applying accurately metered, minute quantities of concentrated additives from bulk sources of supply to successive masses of material presented for treatment includes a pass-through chamber within which separate streams of a liquid carrier and the additive substance are merged together. As the liquid carrier passes through the chamber, the additive, in either dry or liquid form, is likewise directed into the chamber in a metered flow to incrementally combine with the liquid stream and form the combined product. A suction pump at the downstream end of the chamber draws the prepared product out of the chamber and advances it toward an ultimate delivery site. The carrier liquid is prevented from accumulating into a pool within the chamber by the suction pump that cooperates with the upright orientation of the chamber to cause the carrier liquid to swirl smoothly through the chamber. A suction vortex may be created as the product exits the chamber, within which vortex the additive may be directed so as to complete its entrainment with the carrier without causing turbulence. The system can be easily flushed with the liquid carrier after each batch and then dried with an optional air blower.

Abstract: Methods and apparatus for detonating explosives or igniting flammables are disclosed. According to some embodiments of the invention, initiators include an initiating component holding an exploding bridgewire (EBW) or an exploding foil initiator (EFI) and a flammable component housing thermite. An end of the flammable component mates with a corresponding end of the initiating component. A method of initiating the explosives or flammables includes connecting the two components to assemble the initiator, disposing the initiator proximate the explosives or flammables, and activating the initiator to cause ignition of the thermite that then initiates the explosives or flammables. Additionally, a non-explosive kit for the initiator includes the two components with the EBW or EFI initially spaced from the thermite within the flammable component to make the initiator disarmed until final assembly thereof. Cutting torches and perforating guns provide examples of downhole tools that benefit from aspects of the invention.

Title: Auto-ip traffic optimization in mobile telecommunications systems
Inventor: LAU RICHARD
IPC: H04L12/26
Filed: 2004-08-13
Abstract: A system and method for the implementation of fine-grained quality of service in a mobile telecommunications environment uses an Auto-IP policy Decision Point (PDP) to determine what traffic optimizations actions should be taken in reaction to various network conditions. The Auto-IP uses as inputs information from a Gb interface probe to determine the user identification of an IP data flow, information from the radio access network (RAN) network management system (NMS) regarding network congestion. The cell traffic information is passed onto a traffic analysis and processing engine, the Auto-IP PDP which maps the real-time traffic information into an n-dimensional traffic model. An automated policy decision guiding algorithm is executed on the n-dimensional traffic model and selects policy based on the traffic and cell congestion conditions, without human intervention. Additionally, a consistency check is performed to ensure that new policies are consistent with existing policies.  The policy decision outcome is forwarded to the Auto-IP Traffic Optimizer that acts on the network at a point in the network (Gi) that is different from where traffic problem occurs in the RAN. The Auto-IP Traffic Optimizer implements the decisions of the Auto-IP-PDP by performing traffic shaping, TCP  window clamping or other traffic optimizations procedures on a cell-by-cell basis.

Abstract: The present invention provides methods of improving the osteogenic and/or chondrogenic activity of a bone matrix, e.g., a dermineralized bone matrix (DBM), by exposing the bone matrix to one or more treatments or conditions. In preferred embodiments the bone matrix is derived from human bone. The treatment or condition may alter the structure of the bone matrix and/or cleave one or more specific proteins. Cleavage may generate peptides or protein fragments that have osteoinductive, osteogenic, or chondrogenic activity. Preferred treatments include collagenase and various other proteases. The invention further provides improved bone and cartilage matrix compositions that have been prepared according to the inventive methods and methods of treatment using the compositions. The invention further provides methods of preparing, testing, and using the improved bone matrix compositions. Ona assay comprises exposing relatively undifferentiated mesenchymal cells to a bone matrix composition and measuring expression of a marker characteristic of osteoblast or chondrocyte lineage(s). Increased expression of the marker relative to the level of the marker in cells that have been exposed to a control matrix (e.g., an inactivated or untreated matrix) indicates that the treatment or condition increased the osteogenic and/or chondrogenic activity of the bone matrix. Suitable cells include C2C12 cells. A suitable marker is alkaline phosphatase. The inventive methods increase the osteogenic and/or chondrogenic activity of human DBM when tested using this assay system.
