Radio frequency identification (RFID) tags have become widely used by industry, retail sales businesses, and government agencies for tracking materials, products, and inventories. This tracking technology is starting to be applied to the management of emergency responder protective equipment items. This technology has potential for helping to manage the use of emergency apparatus and may become a component of human body worn tracking and locating systems. Current standards governing the application of RFID technology are focused on the industrial sector, and no standards exist for use of the...

This paper reports an experimental technique that is developed for instantaneous planar measurement of droplet size and velocity for dilute sprays in general and sprinkler sprays in particular. This particle tracking technique relies on photographic measurements of two-color fluorescence or fluorescence and Mie scattering from droplets to determine their size and velocity. Measurements were made in a plane that passes through the vertical axis of symmetry of an axis-symmetric sprinkler spray. Drop velocities and drop sizes down to 200 m were measured from the digitized double-exposed...
