  • Patent number: 9415123
    Abstract: Provided herein are nanobubbles designed for use in ultrasound-mediated ablation of cancer cells. The nanobubbles undergo ultrasound-mediated cavitation at an ablation threshold which is significantly decreased, relative to standard ultrasound-mediated treatment of cancer cells. In exemplary embodiments, the nanobubbles comprise an amphiphilic ABC triblock copolymer, wherein block A comprises a hydrophilic polymer, block B comprises a crosslinking polymer, and block C comprises a hydrophobic copolymer comprising (i) methyl methacrylate (MMA) and (ii) a fluorinated monomer, wherein the fluorinated monomer is present in the hydrophobic copolymer of block C at 25 mole percent or less. Related treatment and diagnostic methods, as well as materials relating to the nanobubbles are provided herein. Methods of making a random copolymer are furthermore provided herein.

  • Publication number: 20110130137
    Abstract: Embodiments are described herein to provide a general approach to wireless outage recovery. One general approach involves network equipment detecting (101) an outage condition for a wireless coverage area. In response to detecting the outage condition, the network equipment adjusts (102) a tilt setting of an antenna at a wireless node having a neighboring wireless coverage area. The wireless node then provides (103) wireless service to at least a portion of the wireless coverage area to mitigate the outage condition. Ideally, the wireless node provides wireless service to one or more areas of high traffic density within the outage area.

  • Patent number: 6308986
    Abstract: A restraint belt presenter assembly includes a restraint belt positioning member carried by a slidable member that is selectively driven by a track drive mechanism to move a restraint belt buckle assembly forward from its unused, storage position to a presentation position for easy grasping by a vehicle seat occupant. The slidable member is connected to a track that may optionally be pivotally mounted to elevate the restraint belt positioning member into the presentation position. Alternatively, the track member may include an inclined distal end, such that the slidable member moves upwardly into the presentation position. Another embodiment includes a pivoting shaft member that pivots the restraint belt buckle assembly forward for a starting position to the presentation position as the slidable member travel upwardly on an inclined track.

  • Publication number: 20010020783
    Abstract: A restraint presentation system is disclosed that includes a movable presenting member, such as an armrest or an actuating arm, that moves between a presenting position and a storage position and a restraint belt connected to a tensioning mechanism. The presenting member preferably has a concave shaped portion on a distal end thereof that captures a contact portion of the restraint belt to position the restraint belt in an operational position so as to be accessible to a vehicle occupant. The tensioning mechanism biases the restraint belt into a retracted position when the presenting member is in the storage position such that the contact portion of the restraint belt is in a co-linear relationship with the concave shaped portion of the presenting member.

  • Patent number: 6247744
    Abstract: A vehicle component sub-assembly having self-aligning appropriately fitted structural members is disclosed wherein a closure member, such as a vehicle door, hood or trunk is integrated with and becomes a structural part of a vehicle body. The sub-assembly includes mating components wherein a first mating component is mounted to the vehicle body and a second mating component is mounted to the closure member in such a manner that the first and second mating components become substantially aligned and structurally engaged with one another. The first mating component includes at least one structural key member formed thereon and the second mating component has a complementary mating receptacle therein. When the first and second mating components are aligned into interlocking engagement, the structural key members and mating receptacles are thereby structurally integrating the vehicle body and the closure member.

  • Patent number: 6196619
    Abstract: A vehicle closure panel includes an outer frame that is connected to a central beam portion to provide a primary structure that resists deformation and efficiently distributes impact forces during a collision. The present invention can be used with or without structural key members and mating recesses to integrate the closure panel with the rest of the vehicle body, depending on design criteria. Also, primary structure of the present invention provides a structural modularity for closure panels that simplifies design by reducing the number of overall parts and uses the primary structure alone to meet the demands for crash testing. Thus, a basic structure is relied on for crash strength while accompanying secondary structures provide cosmetic differences.
