Abstract: An air-reactive chemiluminescent formulation is encapsulated and material ich will catalyze the reaction of the formulation with air is affixed to the outside of the capsule. When the capsule is crushed, the formulation, air and the catalyst all come into contact with one other and high intensity light is produced rapidly.

Abstract: Chemiluminescent materials are encased in a thin, highly frangible shell to orm a quantity of microcapsules which, when distributed evenly and in adequate concentration over a perimeter zone, detect infiltration of troops, vehicles, etc. by the chemiluminescence which results from the crushing of the shells. One distribution system uses capsules filled with a chemiluminescent material such as tetrakisdimethylaminoethylene (TMAE). When the capsules are crushed and the contents are exposed to atmospheric oxygen this material oxidizes vigorously to produce a relatively long-lasting chemiluminescence. Another two-component system utilizes capsules containing different chemical components which, when crushed and combined one with the other, produce the chemiliminescence. Both systems employ a shell formed of a film-forming coating material hardenable, into a water-soluble, air tight shell non-reactive with the active filler material.
