    Abstract: A radial fan assembly (18,20,30) for use in a powered air purifying respirator (10) includes at least an impeller (36), a printed circuit board (31) and a scroll casing (22). The scroll casing has a first (34) and a second (31) scroll casing element. The second scroll casing clement includes at least a portion of the printed circuit board. When the radial fan assembly is used in a powered air purifying respirators, the respirator may also include components such as a filter assembly (26).

    Abstract: A detector plate for use in a radiation imaging system includes a first conductive layer, a dielectric layer, a photoconductive layer and a second conductive layer, arranged as a stack in that order. The first conductive layer and the dielectric layer are substantially transparent to radiation energy so as to allow the energy to pass therethrough to be received by the photoconductive layer. The first conductive layer has a periphery defined by a first edge, and the dielectric layer has a periphery defined by a second edge, wherein the first edge is offset inward of the second edge defining a margin between the first and second edges. In use, this margin helps inhibit electrical arcing from the first conductive layer to the second conductive layer when a high voltage is applied between these two layers. A preferred embodiment of the detector plate includes an electrically insulative barrier of silicone based Sylgard in the margin around the periphery of the first conductive layer in the form of a 'dam' to further prevent arcing and resulting detector plate failure. It is also preferable to include a linear contact on the first conductive layer adapted to connect a high voltage electrode of a power supply to the first conductive layer. The first conductive layer is more stable with the linear contact, as compared to a conventional circular contact.

    Abstract translation: 用于放射线成像系统的检测器板包括依次布置为堆叠的第一导电层，电介质层，光电导层和第二导电层。 第一导电层和电介质层对辐射能基本上是透明的，从而允许能量通过，以被光电导层接收。 所述第一导电层具有由第一边缘限定的周边，并且所述介电层具有由第二边缘限定的周边，其中所述第一边缘在所述第二边缘的内侧偏移，在所述第一边缘和所述第二边缘之间限定边缘。 在使用中，当在这两层之间施加高电压时，该余量有助于抑制从第一导电层到第二导电层的电弧。 检测器板的优选实施例包括以“大坝”的形式围绕第一导电层周边的边缘的硅基Sylgard的电绝缘屏障，以进一步防止电弧并导致检测器板故障。 还优选在适于将电源的高压电极连接到第一导电层的第一导电层上包括线性接触。 与常规圆形接触相比，第一导电层与线性接触更稳定。
