摘要： A filter cartridge 12 that has a first and second layer of filter media 38, 40 that each have first and second major surfaces 32, 44 and a perimeter 46 and that each contain active particulate that is bonded together. A plenum 42 is disposed between the first and second layers of filter media 38, 40 such that the plenum 42 interfaces with the second major surface 44, 44′ of each layer of filter media. A housing sidewall 30 extends from the first layer of filter media 38 to the second layer of filter media 40 and is secured to the perimeter 46 of the first and second layers of filter media. The first major surfaces 32, 32′ of the first and second layers of filter media 38, 40 are each fluid permeable and are each in fluid communication with an exterior gas space. A filter cartridge 12 having such a construction provides a bifurcated flow pattern in a higher volume structure.

摘要： A portable cooling or respiratory blower system of the type carried by a user's body includes a housing having two air flow chambers. An impeller is rotatably disposed between the two air flow chambers and includes a base wall that places the two air flow chambers in non-fluidic communication when the impeller is rotated. A separate plurality of blades is provided on each side of the base wall.
摘要翻译：由用户身体携带的便携式冷却或呼吸鼓风机系统包括具有两个空气流动室的壳体。叶轮可旋转地设置在两个气流室之间，并且包括底壁，当叶轮旋转时将叶轮放置在非流体连通状态。在基壁的每一侧设置单独的多个叶片。
