  • Patent number: 7722842
    Abstract: A method for mineral sequestration of pollutant gases resulting from the combustion of carbon-based fuels such as carbon and sulfur dioxides is provided and includes, providing a particulate magnesium-containing mineral and exposing the magnesium-containing mineral to a weak acid to dissolve magnesium from the mineral and form a magnesium-containing solution. The surface of the particulate magnesium-containing mineral is physically activated to expose and dissolve additional magnesium into the solution. Pollutant gases such as carbon dioxide are mixed with the magnesium-containing solution. When the pH of the magnesium-containing solution is increased, solid magnesium carbonate is formed.

  • Patent number: 7723154
    Abstract: A p-type ZnO-based II-VI compound semiconductor layer has silver, potassium and/or gold dopants therein at a net p-type dopant concentration of greater than about 1×1017 cm?3. A method of forming the layer includes using an atomic layer deposition (ALD) technique. This technique includes exposing a substrate to a combination of gases: a first reaction gas containing zinc at a concentration that is repeatedly transitioned between at least two concentration levels during a processing time interval, a second reaction gas containing oxygen and a p-type dopant gas containing at least one p-type dopant species selected from a group consisting of silver, potassium and gold. A concentration of oxygen in the second reaction gas may also be repeatedly transitioned between at least two concentration levels.

  • Patent number: 7724110
    Abstract: A switchable bandpass filter includes a coupled line segment (comb) including a plurality of coupled transmission lines of substantially equal lengths that are each connected or otherwise coupled to the common RF ground at their first end, a plurality of adjustable capacitors each coupled proximate a second end of respective ones of the transmission lines, and a plurality of shunt switches coupled to points along a length of each of the transmission lines. Shunt switches may be implemented by various device technologies including MEMS and FET switches and PIN diodes. The adjustable capacitors may be implemented as an array or tree of switched capacitors using suitable switching components (e.g., as previously enumerated) or by other suitable electrically controllable devices such as varactors or varactor arrays. A differential switchable filter may be formed by the symmetric repetition of individual bandpass filter modules.

  • Patent number: 7718962
    Abstract: The present invention is directed to a defect imaging device that has an energy beam that is directed at a device under test. The energy beam creates positrons deep within the material of the device under test. When the positrons combine with electrons in the material they produce a pair of annihilation photons. The annihilation photons are detected. The Doppler broadening of the annihilation photons is used to determine if a defect is present in the material. Three dimensional images of the device under test are created by directing the energy beam at different portions of the device under test.

  • Patent number: 7717274
    Abstract: A newborn transfusion cell washing device generally comprising a disposable, graduated test tube shaped container having a cap with an inlet port, an injection/sampling port, a suction port, and a vent. The container is capable of being inserted into a conventional clinical centrifuge. The device requires a relatively small volume to operate, 25 ml or less per procedure, and can be performed easily by any hospital blood bank technologist without any special skills. Washed RBCs can be provided to the patient in a timely manner, without the need for “fresh blood.” Any in-dated RBCs can be washed to remove excessive potassium and other toxins. The main RBC aliquot can be saved and repeatedly sampled until the unit is expired or exhausted. This provides a cost savings to the hospital and more importantly, minimizes the recipient's donor exposure.

  • Patent number: 7718279
    Abstract: An epitaxial Ni3FeN film with unique magnetic properties such as single magnetic domain (even in a large scale 0.5?×0.5?), which rotates coherently in response to the desired switching field with a very sharp transition is described. The magnetic hysteresis loop of this new magnetic nitride is close to the perfect ideal square with the same value of saturation magnetization, remnant magnetization, and magnetization right before switching (domain reversal). The switching field is tunable which make this material more attractive for magneto-resistive devices such as MRAM's, read heads and magnetic sensors.
