Abstract: A gas-washout vent includes a housing with a first wall with one or more passages through the wall configured to provide fluid communication with a portion of the patient interface system exposed to a therapy pressure. The passages include respective first openings on a first surface of the first wall. The housing at least partially defines a second opening in communication with ambient atmosphere. A diffusing material is located at least partially within the housing to be adjacent the first surface. A surface of the diffusing material facing the first surface is spaced away from the first surface by a gap that extends to provide a fluid communication between all of the first openings and between all of the first openings and the second opening. The housing is configured so that air is prevented from flowing out of the housing at all areas directly opposite each of the first openings.

Abstract: Example implementations relate to an insertion key assembly for a pluggable module. The insertion key assembly includes a stopper element having a stopping tab, a biasing element, and a driver element having a driving tab. The biasing element is connected to the stopper element and the driver element. In a relaxed state of the biasing element: i) the stopper element is pushed outwards by the biasing element to protrude the stopping tab into a passageway defined by a plurality of walls of a chassis, to block insertion of the pluggable module inside the passageway, and ii) the driver element is pushed outwards by the biasing element to protrude the driving tab into adjacent passageway. In a biased state of the biasing element, the stopper element is pulled inwards by the biasing element to retract the stopping tab from the passageway to allow insertion of the pluggable module inside the passageway.

Abstract: A technique and corresponding device to provide for a floating heat sink is disclosed. The technique includes a method that allows for insertion of an electronic component (e.g., an optical transceiver) into a cage that has a pre-installed heatsink. At the beginning phases of insertion, no friction is present between the electronic component and the heatsink. At or very near an insertion end phase (the electronic component is almost fully inserted), an actuator (e.g., roller or button) is impacted to impart a pivot motion via a lever arm to cause lowering of the heatsink toward the electronic component. A thermal interface material (TIM) may therefore be present to establish a thermal coupling between the heatsink and the electronic component. The TIM and heatsink contact the electronic component via a downward motion (caused by the pivot) to provide a nearly frictionless sliding impact to the TIM.

Abstract: A gas-washout vent includes a housing with a first wall with one or more passages through the wall configured to provide fluid communication with a portion of the patient interface system exposed to a therapy pressure. The passages include respective first openings on a first surface of the first wall. The housing at least partially defines a second opening in communication with ambient atmosphere. A diffusing material is located at least partially within the housing to be adjacent the first surface. A surface of the diffusing material facing the first surface is spaced away from the first surface by a gap that extends to provide a fluid communication between all of the first openings and between all of the first openings and the second opening. The housing is configured so that air is prevented from flowing out of the housing at all areas directly opposite each of the first openings.

Abstract: A hand held electronic device (50) has a flip cover (52) movable between a latched closed position and an open position, the flip cover (52) being slidable in a closed position along a sliding axis between a latched position and an unlatched position whereby in the unlatched position the flip cover (52) is rotatable between a closed position and an open position about a rotational axis transverse to the sliding axis. The flip cover (52) is securable in a latched closed position and an unlatched open position by frictional engagement between gripping fingers at opposite ends of parallel tracks in which rollers attached to the flip cover hinge shaft are able to travel.
