Abstract: A centrifugal gas compressor with rotating hollow housing and an independently rotating, turbine compresses gas bubbles in capillary tubes and recovers energy from the liquid drain (sometimes a liquid recycler). The housing rotatably retains an internal spool having the turbine. Gas-liquid emulsion fed to the capillaries generates compressed gas-liquid emulsion at a radially distal annular region in an annular lake within the spool. Compressed gas leaves the lake and is ported away. A turbine blade edge in spilt over liquid drives the turbine, converting angular velocity/momentum into shaft torque as recovered energy. Blade captured liquid is recycled to capillary inputs.

Abstract: The gas compression method/system restricts flow of emulsified liquid-gas mixture through many substantially radial capillary tube-passages in a rotating disk by either one-way valves, narrowing the passages, hydraulic impedance and/or reinforcement of coriolis forces in terminal end tail segments of the capillary passages. Compressed gas is released from peripherally collected compressed gas-liquid emulsion (beyond the terminal ends of the tubes) in a arcuate peripheral disc space when the compressed gas bubbles emerge from the peripherally collected emulsion. A compressed gas drain draws off gas from the peripheral space. Liquid drain draws off liquid from the space. In different embodiments, radial outboard flow through the capillaries is effected by various one-way valves which may be a single valve in the passage or multiple valves. Coriolis force in tail segments is enhanced by angular displacement in the direction of rotation. Valves may be used in combination with such tail-end segments.

Abstract: The compressor compresses gas in capillaries leading to a radially distant annular container space. Centrifugal force acts on gas bubbles entrained between liquid slugs moving radially outward through the capillaries which may be radial, tangential or continuously curved. Compressed gas is collected in the annular space. A gas-liquid emulsion is fed to the capillaries by an inboard emulsification device. The emulsification may include a vortex generator, an ejector or a venturi injector, all feeding the gas-liquid mixture into the inboard ends of the capillaries. The capillaries are formed in a series of discs, coaxially stacked with outer disc ends open to the annular space. Capillary inlets may be perpendicular, tangential or may define a venturi jet.

Abstract: A method and apparatus, often implemented in a building management system, may include receiving data indicative of a threat level identifier, and subsequently receiving a user instruction to associate one or more sets of building system configuration data with the threat level identifier. Each set of building system configuration data may relate to a respective building system. The instruction may be processed to selectively associate the one or more sets of building system configuration data with the threat level identifier. Subsequently, in response to an instruction to implement a threat level corresponding to the threat level identifier, signals may be generated and transmitted thereby to instruct the relevant building systems to apply configuration data corresponding to the one or more data sets associated with the threat level identifier.

Abstract: Described herein are systems and methods for controlling a building management system (BMS). The present embodiments are directed towards systems and methods that allow a user to implement threat levels in the context of a BMS. In broad terms, aspects of the technology described herein allow a user to define sets of configuration data for various building systems, and associate those sets of data with threat levels. In response to a change in conditions, a user selectively implements a different threat level, which causes the relevant configuration data to be applied to the various building systems. One embodiment provides a method, implemented in a computer system, including receiving data indicative of a threat level identifier, and subsequently receiving a user instruction to associate one or more sets of building system configuration data with the threat level identifier. Each set of building system configuration data relates to a respective building system.
