摘要： An encapsulated stator assembly for use in stator-driven devices is disclosed. The encapsulated stator assembly includes a stator and a covering portion that envelops the stator. The purpose of the covering portion is multi-fold: first, the covering portion serves as a means for mounting and securing the stator, such as within the outer housing of an x ray tube. Second, the covering portion is thermally conductive to enable heat produced by the stator during operation to be dissipated to the outer housing of the x-ray tube thereof. Additionally, the covering portion can include an x-ray absorbent material to reduce x-ray emission from the x-ray tube. Though x-ray tubes represent one advantageous application, the encapsulated stator assembly of the present invention can be used in a variety of motor and stator-driven devices. The encapsulated stator assembly is especially well suited for use in dirty or dusty environments.

摘要： In one embodiment, a method of examining an object is disclosed comprising scanning an object at first and second radiation energies, detecting radiation at the first and second energies, and calculating a function of the radiation detected at the first and second energies. The function may be calculated for corresponding portions of the object. It is determined whether the object at least potentially comprises high atomic number material having an atomic number greater than a predetermined atomic number based, at least in part, on the function. The function may be a ratio. The function may be compared to a second function, which may be a threshold having a value based, at least in part, on material of the predetermined atomic number. The second function may be the same as the first function.
