Abstract: Methods and systems are provided having a tag associated with a moving object are disclosed. An antenna of the tag transmits signals. A Global Positioning System (GPS) obtains GPS data for the tag. An anchor comprises an antenna that receives signals transmitted by the tag at the first frequency. A computer system receives both GPS data and information from the anchor indicative of a distance between the tag and the anchor and determines whether to track a position of the tag. A camera system includes a communication system that receives information about the position of the tag from the computer system. The camera system includes a camera control system that controls a position of a camera based on received information about the position of the tag from the computer system.

Abstract: A system for characterizing suspended particles in a water treatment facility is disclosed. The system uses an imaging array to take multiple images of the particles in a sample volume. These images are then processed to determine geometrical properties of individual particles in the sample. These geometric properties can then be used to identify properties of the sample volume such as particle volume concentration, particle number concentration, computed particle diameter, gravitational settling velocity, mass concentration, and computed particle volume.
