Abstract: A system communicate with a plurality of units. Each of the plurality of units includes a two dimensional camera, a three dimensional camera, a multispectral camera, and/or an inertial measurement unit. Each of the plurality of units is associated with a person, a vehicle, or a robot, and each of the units collects data relating to an environment. The system receives the data relating to the environment from the plurality of units, and uses the data from each of the plurality of units to estimate the positions of the units and to track the positions of the units. The system enables the plurality of units to communicate with each other regarding the collection of the data relating to the environment, commingles and analyzes the data from the plurality of units, and uses the commingled and analyzed data to build a three-dimensional map of the environment.

Abstract: A process for removing organic compounds from a brine solution permits processing of that solution in a chlor-alkali electrochemical cell. A brine solution containing a mixture of nonvolatile organic compounds is introduced into a tank with a selected volume of acid and is heated to boiling. Nonvolatile organic compounds in the solution are decomposed such that they become volatile compounds, which are removed by distillation from the tank or by additional subsequent steam distillation. The resulting brine solution has a final total organic compound (TOC) level sufficiently low to render its suitable for use in a membrane, diaphragm or other type of chlor-alkali electrochemical cell.
