The various technologies presented herein relate to isolating an integrated circuit from electromagnetic radiation/interference. The integrated circuit can be encapsulated in a coating (e.g., a conformal coating). A conductive layer can be formed over the coating, where the conductive layer is deposited to connect with an electromagnetic shielding layer included in a substrate upon which the integrated circuit is located thereby forming a Faraday cage around the integrated circuit. Hollow spheres can be included in the coating to improve the dielectric constant of the coating. The conductive layer can be formed from at least one of metallic material or a polymer coating which includes conductive material. The integrated circuit can be utilized in conjunction with a heat sink and further, the integrated circuit can be of a flip chip configuration.

Diamagnetic composite material structure for reducing undesired electromagnetic interference and eddy currents in dielectric wall accelerators and other devices

Patent Caporaso, George J. ; Poole, Brian R. ; Hawkins, Steven A.

The devices, systems and techniques disclosed here can be used to reduce undesired effects by magnetic field induced eddy currents based on a diamagnetic composite material structure including diamagnetic composite sheets that are separated from one another to provide a high impedance composite material structure. In some implementations, each diamagnetic composite sheet includes patterned conductor layers are separated by a dielectric material and each patterned conductor layer includes voids and conductor areas. The voids in the patterned conductor layers of each diamagnetic composite sheet are arranged to be displaced in position from one patterned conductor layer to an adjacent patternedmore »« less

Chemical isolation of .sup.82 Sr from proton-irradiated Mo targets

Patent Grant, Patrick M. ; Kahn, Milton ; O'Brien, Jr., Harold A.

Spallation reactions are induced in Mo targets with 200-800 MeV protons to produce microcurie to millicurie amounts of a variety of radionuclides. A six-step radiochemical procedure, incorporating precipitation, solvent extractions, and ion exchange techniques, has been developed for the separation and purification of Sr radioactivities from other spallation products and the bulk target material. Radiostrontium can be quantitatively recovered in a sufficiently decontaminated state for use in biomedical generator development.

Ultrasonic thermometer isolation standoffs

Patent Arave, Alvin E.

A method is provided for minimizing sticking of the transmission line to the protective sheath and preventing noise echoes from interfering with signal echoes in an improved high temperature ultrasonic thermometer which includes an ultrasonic transmission line surrounded by a protective sheath. Small isolation standoffs are mounted on the transmission line to minimize points of contact between the transmission line and the protective sheath, the isolation standoffs serving as discontinuities mounted on the transmission line at locations where a signal echo is desired or where an echo can be tolerated. Consequently any noise echo generated by the sticking of themore »« less

Pump isolation valve

Patent Kinney, Calvin L. ; Wetherill, Todd M.

The pump isolation valve provides a means by which the pump may be selectively isolated from the remainder of the coolant system while being compatible with the internal hydraulic arrangement of the pump during normal operation of the pump. The valve comprises a valve cylinder disposed around the pump and adjacent to the last pump diffuser with a turning vane attached to the lower end of the valve cylinder in a manner so as to hydraulically match with the discharge diffuser. The valve cylinder is connected to a drive means for sliding the valve cylinder relative to the diffuser supportmore »« less

Extracellular nonmitogenic angiogenesis factor and method of isolation thereof from wound fluid

Patent Banda, Michael J. ; Werb, Zena ; Knighton, David R. ; Hunt, Thomas K.

A nonmitogenic angiogenesis factor is isolated from wound fluid by dialysis to include materials in the molecular size range of 2,000 to 14,000, lyophilization, and chromatography. The nonmitogenic angiogenesis factor is identified by activity by corneal implant assay and by cell migration assay. The angiogenesis factor is also characterized by inactivity by mitogenesis assay.
