Abstract: Techniques for selecting a serving base station for a terminal in a wireless communication network are described. In one design, multiple candidate base stations for the terminal may be identified, with each candidate base station being a candidate for selection as the serving base station for the terminal. The multiple candidate base stations may include base stations with different transmit power levels and/or may support interference mitigation. One of the multiple candidate base stations may be selected as the serving base station. In one design, the serving base station may be selected based on at least one metric for each candidate base station. The at least one metrics may be for pathloss, effective transmit power, effective geometry, projected data rate, control channel reliability, network utility, etc. The selected candidate base station may have a lower SINR than a highest SINR among the multiple candidate base stations.

Abstract: Method and apparatus for an access termi-nal which makes handoff decisions between a number of potential alternative attachment points based on service level indicating metrics are described. The access terminal computes a service level indicating metric differently for a current connection than for a potential alternative connec-tion.    A service level indicating metric is a function of load-ing information and received signal strength. A selection may be made by selecting between attachment points by se-lecting the attachment point having the highest service lev-el indicating metric from among a plurality of attachment points, one per possible carrier where the attachment point which is considered for a given carrier is the one having the best connection for the given carrier. The access termi-nal handoff decision approach provides handoff decisions which are nearly as optimal as those which can be achieved using a centralized control node but without the require-ment for centralized handoff decisions.

Abstract: There is provided a process for the capture and sequestration of carbon dioxide that would otherwise enter the at-mosphere and contribute to global warming and other problems. CO2 capture is accomplished by reacting carbon dioxide in flue gas with an alkali metal carbonate, or a metal oxide, particularly containing an alkaline earth metal or iron, to form a carbonate salt. A preferred carbonate for CO2 capture is a dilute aqueous solution of additive-free (Na2CO3). Other carbonates include (K2-CO3) or other metal ion that can produce both a carbonate and a bicarbonate salt. Examples of suitable metal oxides include sev-eral alkaline earths including CaO and MgO. The captured CO2 is preferably sequestered using any available mineral or industrial waste that contains calcium magnesium or iron in non- carbonate forms, or iron in the Fe+2 oxidation state.

Abstract: Matrix metalloproteases (MMPs) play many important roles in normal and pathological remodeling processes including atherothrombotic disease, inflammation, angiogenesis and cancer. This invention relates to the activation of protease-activated receptor-1 (PAR-1) by endogenous platelet MMP-1 collagenase on the surface of platelets. Exposure of platelets to fibrillar collagen converts the surface-bound pro-MMP-1 zymogen to active MMP- 1, which promotes aggregation through PAR-1, MMP-1 is shown to cleave the PAR-1 extracellular domain at a novel site, which then strongly activates Rho-GTP  signaling pathways, cell shape change and motility, and MAPK signaling. Blockade of MMP-PAR 1 suppresses thrombogenesis under arterial flow conditions and inhibited thrombosis in animals. These studies provide a link between matrix-dependent activation of metalloproteases and platelet-G protein signaling and identify MMP- 1/PAR-1 as a new target for the treatment and prevention of arterial thrombosis and other thrombotic diseases.

Abstract: An apparatus and method for stabilizing a cannula (68) to a vascular structure. The stabilizer (66) includes a ring (78) that circumferentially surrounds the cannula (68). Three or more struts (80) extend distally from the ring (78) and are outwardly-deflected by a first angle relative to a first axis that is parallel to a lengthwise central axis of the cannula (68). Each strut (80) includes a contact pad (82) that radially extends from the strut (80) and is distally-deflected by a second angle relative to a second axis that is orthogonal to the first axis. Three or more arms (84) extend proximally from the ring (78) and each arm (84) opposes one of the struts (80). The arms (84) are inwardly- deflected by a third angle relative to the first axis. The stabilizer (66) is configured to move relative to the cannula (68) until the contact pads (82) engage the vascular structure (67), causing the arms (84) to engage and resist further movement of the stabilizer (66) relative to the cannula (68).

Inventor: KILGORE MARION DEWEY
IPC: E21B33/1295
Filed: 2010-11-11
Granted: 2014-07-22
Abstract: A method is provided which releases and retrieves an opposed slip downhole tool (10) by reducing the compressive forces on the sealing elements (42) prior to unsetting the slip assemblies (20, 60). Further, the method does so without damaging the slip assemblies. The method provides for the retrieval of the entire downhole tool including all of its component parts, requiring but a single trip within the wellbore. When the tool is to be retrieved, the sealing element is disengaged from the casing by relaxing the compression forces on the sealing element. Then the slip assemblies are disengaged from the casing such that the slip assemblies are no longer in gripping engagement with the casing. The tool is then retrieved from the wellbore. The step of disengaging the sealing assembly can be performed by radially contracting the sealing element with or without longitudinally expanding the sealing element.
