Abstract: The present disclosure is directed to systems and techniques for providing immersive and interactive three-dimensional (3D) mapping data and visualizations thereof for emergency response incidents. In one example, the systems and techniques can obtain location information associated with an incident and obtain one or more portions of three-dimensional (3D) mapping data based on the location information associated with the incident. A 3D scene associated with the incident can be generated, wherein the 3D scene is generated based on the one or more portions of 3D mapping data. A first 3D view of the 3D scene can be generated, wherein the first 3D view includes one or more incident location indicators representing the location information of the incident relative to the 3D scene.

Abstract: Methods, devices, and systems for operating a fire system network are described herein. One method includes receiving a plurality of time-slotted maintenance messages over a period of time from each of a plurality of fire system devices located in a facility via a first spreading factor, receiving an event message from a fire system device of the plurality of fire system devices responsive to the fire system device determining a fire event, the event message sent via a second spreading factor, and sending a block actuate message to the plurality of fire system devices responsive to receiving the event message, wherein the block actuate message is configured to activate a fire alarm.

Abstract: Machine vision methods and systems determine if an object within a work field has one or more predetermined features. Methods comprise capturing image data of the work field, applying a filter to the image data, in which the filter comprises an aspect corresponding to a presumed feature, and based at least in part on the applying, determining if the object has the presumed feature. Systems comprise a camera system configured to capture image data of the work field, and a controller communicatively coupled to the camera system and programmed to apply a filter to the image data, and based at least in part on applying the filter, determine if the object has the specific feature. Robotic installation methods and systems that utilize machine vision methods and systems also are disclosed.

Abstract: A cyclic process having reduced hydrocarbon emission is provided for oxyhydrochlorination of ethylene to produce ethylene dichloride employing substantially pure oxygen as feed to the oxyhydrochlorination unit and recycling a major portion of the residual gas stream from which ethylene dichloride has been recovered as condensate, wherein reactant feed rates are adjusted to maintain recycle gas stream composition within specified limits.

Abstract: Process is provided for removal of chloroprenes as impurities from ethylene dichloride streams formed in the production of vinyl chloride by the thermal cracking of ethylene dichloride. The ethylene dichloride stream is subjected to distillation in a distillation zone to which free chlorine gas is introduced, thereby chlorinating the chloroprenes contained therein and forming higher boiling chlorocarbons as reaction products. The higher boiling chlorocarbons, together with ethylene dichloride, may be removed as bottoms and passed to a second distillation zone for separation of ethylene dichloride from the higher boiling impurities, thereby producing a substantially pure ethylene dichloride which may be recycled to the cracking step.

Abstract: A process is provided for removing vinyl chloride from gaseous streams containing the same wherein the gaseous vinyl chloride stream is contacted with a hypochlorous acid solution for substantially complete absorption and reaction of the vinyl chloride, thereby minimizing the hazards associated with passage of vinyl chloride monomer to the atmosphere.
