  • Patent number: 10168288
    Abstract: A radiography imaging system for generating images of a pipe assembly includes a radiation source for emitting rays. The pipe assembly includes at least one of a pipe, tubing, and a weld. The radiation source includes a radioactive isotope having an activity level within a range between about 1 Curie and about 40 Curies. The radiation source is positioned adjacent a portion of the pipe assembly. A detector is positioned opposite the radiation source. The portion of the pipe assembly is positioned between the radiation source and the detector such that the rays interact with the portion of the pipe assembly and strike the detector. The detector includes an imaging plate that is activated by illumination with the rays with an exposure within a range between about 0.5 Curie-minute and about 5 Curie-minutes of radiation. The imaging plate has a thickness within a range between about 5 mm and about 15 mm.

  • Patent number: 8450926
    Abstract: An article of manufacture comprises a thin film solid state lighting device, such as an organic light emitting diode (OLED) device, having a planar light emitting side and an opposite planar mounting side and including electrodes disposed on the planar mounting side of the thin film solid state lighting device, the electrodes including a magnetic material configured to conductively convey electrical drive current to drive the thin film solid state lighting device to emit light at the planar light emitting principal side. The article of manufacture may further comprise a fixture having a planar surface with magnets arranged to mate with the electrodes to magnetically secure the thin film solid state lighting device with the fixture and to concurrently form electrically conductive paths including the magnetic material of the electrodes configured to conductively convey electrical drive current. Thus this magnetic connection provides both mechanical support and electrical conduction path.
