Abstract: An attenuation mechanism for an electronic device is presented. The attenuation mechanism includes an outer member that has an inner member oriented axially within the outer member. The inner member has an axial twist that causes a line of sight blockage between an exterior and an interior of a housing of an electronic device when the attenuation mechanism is mounted through the housing, such that sound and electromagnetic radiation is attenuated without obstructing cooling air that is flowing through the housing.

Abstract: Air moving device (AMD) packaging apparatus includes an AMD carriage structure and an associated frame receiving the AMD carriage structure. The AMD carriage structure includes an AMD holder section pivotally connected to a driver section. The associated frame is mounted in a housing of a system to be cooled and includes elongated slots defining cooperating tracks for receiving the AMD carriage structure. The AMD holder section and the driver section include outwardly extending protrusions or posts slideably received within the cooperating tracks in the associated frame to position an AMD contained within the AMD holder section in an operating position within the associated frame.

Abstract: An ultraviolet (UV) device increases turbulent air flow in a duct, decreasing air flow velocity in the vicinity of the UV device, increasing exposure time of contaminants to UV light, and improving kill rates for contaminants. An arrangement of UV light sources increases UV intensity along the axis of fluid flow.
