Abstract
An adapter assembly for attaching a device, such as a communication device, to a portion of a mask, such as a filter port. The assembly includes an adapter ring that attaches to the mask to effect a seal of the filter port. A mounting assembly attaches to the device and is releasably engageable with the adapter ring to support the device on the mask for rotation relative to the mask without breaking the seal of the filter port. Preferably the adapter ring attaches to the mask with a threaded connection, and the device rotates on the adapter ring with less force in a loosening direction of the threaded connection.
