  • Publication number: 20140234665
    Abstract: A perpendicular magnetic recording disk includes a template layer below a Ru or Ru alloy underlayer, with a granular Co alloy recording layer formed on the underlayer. substrate. The template layer comprises nanoparticles spaced-apart and partially embedded within a polymer material, with the nanoparticles protruding above the surface of the polymer material. A seed layer covers the surface of the polymer material and the protruding nanoparticles and an underlayer of Ru or a Ru alloy covers the seed layer. The protruding nanoparticles serve as the controlled nucleation sites for the Ru or Ru alloy atoms. The nanoparticle-to-nanoparticle distances can be controlled during the formation of the template layer. This enables control of the Co alloy grain diameter distribution as well as grain-to-grain distance distribution.

  • Publication number: 20140135698
    Abstract: The invention relates to a swallowable medication capsule capable 200 of dispensing fluid medicine stored in a medication compartment 211 through a valveless exit holt 207. A vent hole 206 enables ventilation of an actuator cavity 212 which houses an actuator used for displacing a surface 205 which separates the medication cavity 211 and the actuator cavity 212. By locating the vent and exit holes close to each other so that contact with contracting parts of the gastrointestinal tract and the exterior surface 221 is not able to prohibit a pressure passageway between the vent and exit holes, creation of a pressure difference of pressures in the medication and actuator cavity is prohibited.

  • Patent number: 8585878
    Abstract: An apparatus and method for electrochemical fluid analysis comprises a chamber (1202) having a depth dimension for accommodating a volume of a fluid under test, first and second electrodes (A1) disposed within the chamber and extending along the depth dimension in spaced relation with each other, and a soluble solid, such as an annealed polymer, e.g. EUDRAGIT occupying a lateral gap between the first and second electrodes. The rate of dissolution as monitored by electrochemical impedance spectroscopy (EIS) of the soluble solid within the fluid depends on the chemical concentration of a corresponding analyte present in solution in the fluid. In one embodiment a silicon-based integrated circuit device defining an upper margin includes an array of electrodes disposed along said upper margin to permit direct exposure of the electrode array to the fluid under test. The device is constructed using CMOS technology.

  • Patent number: 8175690
    Abstract: An optical device for assessing optical depth in a sample illuminated by polarized radiation from a source include two radiation guides having their end portions arranged for capturing reflected radiation from the sample. A detector measures two polarizations of the reflected radiation, and two intensities of the reflected radiation in the two radiation guides, respectively. A processor is configured to calculate two pectral functions, which are indicative of single scattering events in the sample. The processor is further configured to calculate a measure of the correlation between the two spectral functions so as to assess whether the single scattering events originate from substantially the same optical depth within the sample. Thus, the causal relation between the two spectral functions can be used for assessing whether the single scattering events giving rise to the two spectral functions come from substantially the same optical depth within the sample.
