  • Publication number: 20150219652
    Abstract: A method of detecting a non-DNA target includes the use of a first nucleic acid motif linked to a first affinity ligand which binds specifically to the target and having a first toehold domain and a first binding domain, and a second nucleic acid motif linked to a second affinity ligand which binds specifically to the target and having a second binding domain, wherein the first and second binding domains are complementary to each other. Upon contact with the target, the first and second nucleic acid motifs bind to form a target-ligand complex. The formation of the complex causes displacement of an output nucleic acid motif. This method may be used with detectable beacons in an imaging or diagnostic method, and particularly in a point of care diagnostic method.

    Abstract: A relay and distribution apparatus is provided for a cellular communication system. The relay and distribution apparatus includes an antenna system configured to lay down beams in overlapping first and M second N-cell frequency reuse patterns. The first frequency reuse pattern may be for communication of control channels of a cellular communication system, and the second frequency reuse patterns may be for communication of traffic channels exclusive of control channels of the cellular communication system. The second frequency reuse patterns may be staggered with one another. And cells of the second frequency reuse patterns may have a size only a fraction of which is for transmission of traffic channels any of which may be assignable through a control channel of the first reuse frequency pattern.

  • Patent number: 8535463
    Abstract: An uncured acoustic absorbing member (1, 31) for cavity sealing comprises a thermally inert carrier (8, 38) and a thermally expandable material (6, 40) applied to the carrier. The carrier (8, 38) contains openings (3, 33) which become covered when the thermally expandable material is expanded to seal the cavity. The acoustic absorbing members (1, 31) are particularly useful for sealing automotive cavities to provide acoustical abatement and to prevent the entry of fluids into the cavity.

  • Patent number: 7442352
    Abstract: Process for removing sulfur oxides, mercury vapor, and fine particulate matters from industrial flue gases that contain such pollutants. Pollutants are removed by modules, which contain microporous adsorbent (i.e., sorbent) material held within a polymer matrix. The composite material that contains the microporous absorbent material held within a polymer matrix removes sulfur oxides by converting them into high concentration sulfuric acids. SULFURIC acid produced inside the composite material is automatically expelled onto the external surfaces of the composite material and is drained into an acid reservoir together with the fine particulate mailers which are washed from the external surfaces of the composite material by the constant dripping of the sulfuric acid along the external surfaces of the composite material.

  • Patent number: 6964889
    Abstract: A microelectronic package including a microelectronic die having an active surface and at least one side. An encapsulation material is disposed adjacent the microelectronic die side(s). A portion of the encapsulation material is removed to expose a back surface of the microelectronic die which has a metallization layer disposed thereon. A protective layer is disposed on the metallization layer prior to encapsulation, such that when the portion of the encapsulation material is removed, the protective layer prevents the metallization layer from being damaged. After the portion of the encapsulation material is removed, the protective layer is removed and the metallization layer is exposed. A heat spreader may then be attached to the microelectronic die by abutting the heat spreader against the metallization layer and reflowing the metallization layer.
