Antireflective coatings comprising poly(oxyalkylene) colorants

This invention relates to antireflective coatings comprising polymeric polyoxyalkylenated colorants. More particularly, the present invention relates to antireflective coatings for utilization in forming thin layers between reflective substrates and photoresist coatings. Such antireflective coatings are very useful and beneficial within the production and fabrication of semiconductors through photolithographic procedures due to the liquid, non-crystallizing nature of polyoxyalkylenated colorants, and the lack of potentially damaging counterions, metals, and / or electrolytes within the inventive antireflective colored coatings. The inventive coatings may also be applied on lenses, mirrors, and other optical components. Methods of forming such antireflective coatings are also contemplated within this invention.

Implantable devices using rechargeable zero-volt technology lithium-ion batteries

InactiveUS7184836B1Assures safe and reliable operation of systemFirmly connectedElectrotherapyLoad circuitLow voltage
An implantable medical device, such as an implantable pulse generator (IPG) used with a spinal cord stimulation (SCS) system, includes a rechargeable lithium-ion battery having an anode electrode with a substrate made substantially from titanium. Such battery construction allows the rechargeable battery to be discharged down to zero volts without damage to the battery. The implantable medical device includes battery charging and protection circuitry that controls the charging of the battery so as to assure its reliable and safe operation. A multi-rate charge algorithm is employed that minimizes charging time while ensuring the battery cell is safely charged. Fast charging occurs at safer lower battery voltages (e.g., battery voltage above about 2.5 V), and slower charging occurs when the battery nears full charge higher battery voltages (e.g., above about 4.0 V). When potentially less-than-safe very low voltages are encountered (e.g., less than 2.5 V), then very slow (trickle) charging occurs to bring the battery voltage back up to the safer voltage levels where more rapid charging can safely occur. The battery charging and protection circuitry also continuously monitors the battery voltage and current. If the battery operates outside of a predetermined range of voltage or current, the battery protection circuitry disconnects the battery from the particular fault, i.e. charging circuitry or load circuits.

Chimeric viruses presenting non-native surface proteins and uses thereof

The present invention provides chimeric negative-stand RNA viruses that allow a subject, e.g., an avian, to be immunized against two infectious agents by using a single chimeric virus of the invention. In particular, the present invention provides chimeric influenza viruses engineered to express and incorporate into their virions a fusion protein comprising an ectodomain of a protein of an infectious agent and the transmembrane and cytoplasmic domain of an influenza virus protein. Such chimeric viruses induce an immune response against influenza virus and the infectious agent. The present invention also provides chimeric Newcastle Disease viruses (NDV) engineered to express and incorporate into their virions a fusion protein comprising the ectodomain of a protein of an infectious agent and the transmembrane and cytoplasmic domain of an NDV protein. Such chimeric viruses induce an immune response against NDV and the infectious agent.
