Abstract: Medical techniques include systems and methods for administering a positive pressure ventilation, a positive end expiratory pressure, and a vacuum to a person. Approaches also include treating a person with an intrathoracic pressure regulator so as to modulate or upregulate the autonomic system of the person, and treating a person with a combination of an intrathoracic pressure regulation treatment and an intra-aortic balloon pump treatment.

Abstract: A first power train that includes a first plurality of components, and a second power train includes a second plurality of components. The first power train is configured to provide power to a first plurality of server racks of a first data center at a first level of high-availability service associated with a first uptime. The first plurality of components includes a first subset of the first plurality of components and a second subset of the first plurality of components. The second power train is configured to provide power to a second plurality of server racks of the first data center at a second level of high-availability service that is associated with a second uptime that is less than the first uptime. The second plurality of components includes a first subset of the second plurality of components and the second subset of the first plurality of components.

Abstract: Methods, systems, and apparatuses are described that enable the recovery of stranded power in a data center. For example, a power distribution system for recovering stranded power in a data center includes a first power distribution unit (PDU), a first busway segment that is operable to electrically connect the first PDU to a first set of server racks in a first row of server racks, a second busway segment that is operable to electrically connect the first PDU to a second set of server racks in a second row of server racks, a second PDU, a third busway segment that is operable to electrically connect the second PDU to a third set of server racks in a third row of server racks, and a fourth busway segment that is operable to electrically connect the second PDU to a fourth set of server racks in the second row of server racks.

Abstract: A fireproof, bi-directional decompression panel includes a frame member and a pressure relief panel member that is releasably retained to the frame member to removably cover a decompression vent opening of an aircraft partition, such as a sidewall of an aircraft cargo compartment. During a decompression event, the pressure relief panel member is released bi-directionally in either of two opposing directions from the frame member when a predetermined pressure differential exists across the partition. The decompression panel assembly is fire resistant, and has reduced weight and fewer parts than prior conventional decompression panel assemblies.

Abstract: A tracheostomy tube having an inflatable cuff, an inflating means including an indicating balloon, and a pressure relief valve to prevent over-inflation of the balloon and the cuff are disclosed.

Abstract: A relief valve having a main passage normally closed with a main valve member and a vent passage normally closed with a vent valve member, the vent valve member being constructed to open the vent passage upon application of a predetermined pressure into the main valve passage to thereby prevent application of greater than said predetermined pressure to the outlet of the valve is disclosed.
