Abstract: The present application relates to air-cooled electronic devices. An exemplary apparatus has an enclosure including one or more interior surfaces. The interior surfaces at least partially define a plenum. A support member is situated in the enclosure and defines a position reference plane, which can at least partially define the plenum. The apparatus further includes an air-to-fluid heat exchanger situated in the enclosure adjacent the support member, and one or more device bays configured to receive at least one corresponding electronic device. The device bays can be located adjacent the support member such that the position reference plane defines a boundary between the device bays and the plenum. The device bays, the plenum, and the air-to-fluid heat exchanger are in fluid communication with one another along a flow path defined within the enclosure, and the enclosure restricts an air flow along the flow path from exiting the enclosure.

Abstract: A chamber-to-reservoir vented humidification system in which the reservoir is an inverted water bottle elevated above the humidification chamber. A vented cap is provided to couple water from the bottle to the chamber via a supply line coupled between a water port of the cap and a water inlet of the chamber, and to provide a vent between the chamber and the bottle via a vent line coupled between a vent port of the cap and a vent of the chamber. A straw couples the vent port to a space within the inverted bottle spaced from the cap, such as above the water line. The vented cap includes a duckbill valve in the vent port.

Abstract: An apparatus embodying the invention includes a probe head with an interrogation surface that is intended to be positioned adjacent or pushed into contact with a target material or tissue. The probe head is constructed to have a plurality of interrogation devices arranged across the face of the interrogation surface. The probe head is also constructed so that the interrogation device can conform to a non-uniform or non-planar surface of the target tissue. In some embodiments, the interrogation surface may have a particular shape that conforms to the shape of a target material. In other embodiments, one or more portions of the interrogation surface could be movable with respect to the remaining portions so that the interrogation surface could be movable with respect to remaining portions so that the interrogation surface can thereby conform to a non-uniform surface. In still other embodiments, a plurality of separately moveable interrogation devices can be arranged across the interrogation surface.
