SPRINKLER SYSTEM INCLUDING A MIXING DEVICE UPSTREAM OF A SPRINKLER
An exemplary sprinkler system includes a liquid supply conduit and a gas supply conduit. A mixing device is coupled to the liquid supply conduit and the gas supply conduit. The mixing device is configured to establish a mixture of liquid from the liquid supply conduit and gas from the gas supply conduit. The mixture has a selected gas-to-liquid ratio. A sprinkler supply conduit is coupled with the mixing device for carrying the mixture downstream from the mixing device. A sprinkler coupled with the sprinkler supply conduit is configured to receive the mixture and to discharge a fire suppression mist.
An exemplary method of installing misting fire suppression sprinklers into a building previously containing at least one other type of sprinkler includes installing at least one misting fire suppression sprinkler where it can introduce a fire suppression mist into a selected portion of the building. Fluid communication is established between the misting fire suppression sprinkler and a liquid supply conduit previously within the building that has been configured to supply fire suppression liquid to the other type of sprinkler. A gas supply conduit is installed within the building in fluid communication with the missing fire suppression sprinkler. The gas from the gas supply conduit and liquid from the liquid supply conduit allow the misting fire suppression sprinkler to selectively produce a fire suppression mist within the selected portion of the building.
An exemplary device for introducing an agent into a fire suppression fluid includes a housing having an inlet configured to receive the agent into the housing. The housing also has an outlet configured to release the agent from the housing. A stopper is moveable between a closed position where the stopper prevents passage from the inlet to the outlet and an open position where the inlet is in communication with the outlet. A vane causes movement of the stopper from the closed position to the open position responsive to contact between the vane and fire suppression fluid flowing past the vane.
A membrane electrode assembly for a gas sensor is described that includes a membrane disposed between a sensing electrode and a counter electrode. The membrane is a polymer membrane, such as an ionomer, having an ionic liquid retained therein.
A video recording and playback network comprises a video source, a plurality of recorders, a local server, and a client device. The plurality of recorders records video from the video source. The local server generates a playlist comprising one or more ordered video segments which together cover a desired time range. The playlist associates one of the plurality of recorders with each video segment. The client device plays back video according to the playlist by streaming each video segment, in sequence, from the associated recorder.

A sound enhancement device for a detector includes a cylindrical portion having a tubular body and an interior cavity longitudinally coextensive therewith. The device includes a first elongated portion and at least a second elongated portion with both portions coupled to the cylindrical portion. The first elongated portion includes a first body portion having a first cavity that is coextensive with the first body portion while the at least second elongated portion includes a second body portion having a second cavity that is coextensive with the second body portion. The cylindrical portion and each of the first and at least the second elongated portions comprise a length of a quarter wavelength of a predefined frequency. The sound enhancement device includes radii of curvatures for causing a wavefront emanating from the sound enhancement device to maximize the radiation efficiency of the sound enhancement device.
A system for delivery of a fire extinguishing agent includes an agent tank at least partially filled with a volume of liquid fire extinguishing agent and a supply of pressurizing gas operatively connected to inject pressurizing gas into the volume of liquid agent. A discharge valve is configured to open when the agent tank reaches a desired pressure due to the injection of pressurizing gas therein thereby delivering a flow including fire extinguishing agent with associated dissolved pressurizing gas from the agent tank. The flow of fire extinguishing agent and associated dissolved pressurizing gas is discharged from the agent tank.
A wireless device comprises a transceiver and a scheduling system. The transceiver transmits and receives messages to and from an access point, and has a sleep mode from which it occasionally wakes at wakeup times to listen for beacons from the access point. The scheduling system schedules wakeup times according to historical beacon synchronization data.
An auto-commissioning system provides automatic parameter selection for an intelligent video system based on target video provided by the intelligent video system. The auto-commissioning system extracts visual feature descriptors from the target video and provides the one or more visual feature descriptors associated with the received target video to an parameter database that is comprised of a plurality of entries, each entry including a set of one or more stored visual feature descriptors and associated parameters tailored for the set of stored visual feature descriptors. A search of the parameter database locates one or more best matches between the extracted visual feature descriptors and the stored visual feature descriptors. The parameters associated with the best matches are returned as part of the search arid used to commission the intelligent video system.
An exemplary fire suppression system includes a nozzle body configured to carry a fire suppressing fluid to be discharged from a first orifice array and a second orifice array. Gas bubbles can be introduced through a bubbler into the fire suppressing fluid to establish a bubbly mixture in the nozzle. Each first orifice in the first orifice array has a first flow property and is configured to receive the bubbly mixture and through effervescent atomization yield a first fire suppression mist from the first orifice array. Each second orifice in the second orifice array has a second different flow property and is configured to receive the bubbly mixture and through effervescent atomization yield a second fire suppression mist from the second orifice array. The first fire suppression mist and the second fire suppression mist are configured to provide a selected fire suppression nozzle discharge.
A system for boiler control is provided. The system includes supply units to provide supplies of combustion materials for combustion thereof, a vessel coupled to the supply units in which the combustion materials are combusted, a carbon monoxide (CO) sensor disposed at an outlet of the vessel to sense a quantity of exhaust CO output from the vessel as a product of combustion therein and a control unit. The control unit is coupled to the supply units and the sensor and configured to issue a main servo command and a pulse servo command to one or more of the supply units to control operations of the one or more supply units in accordance with the sensed quantity of the exhaust CO.
