Methods of delivery of encapsulated perfluorocarbon taggants
First Claim
1. A device for emitting a taggant into an environment, comprising:
- a taggant reservoir;
an electronic disperser, configured to disperse the taggant from the reservoir into the environment based on an electronic input signal which causes a dispersion of the taggant from the electronic disperser corresponding to the electronic input signal;
an electronic control, configured to operate the electronic disperser according to a release profile by generation of the electronic input signal; and
a port, configured to receive information defining the release profile.

Abstract
A system and method for tagging, tracking, locating and identifying people and vehicles transporting people using Perfluorocarbon tracers. An on-going problem faced by military as well as law enforcement personnel is that of friendly fire incidents. To prevent possible friendly-fire incidents, troops would separate the two layers of the uniform patch, thereby releasing a controlled release of the Perfluorocarbon vapors. Other “friendly” troops, equipped with sensors tuned to the specific perfluorocarbon characteristics would thus be able to literally view a plume around the tagged person or object. The system may conversely be used to tag enemies. Formulations of mixed perfluorocarbons may be used to provide coding of emissions.

14. A method for emitting a taggant into an environment, comprising:
-
providing a taggant in a taggant reservoir; receiving information defining a release profile; storing the received information defining the release profile in an electronic memory; and controlling an electronic disperser, to disperse the taggant from the taggant reservoir into the environment, in response to a control signal generated by an electronic control according to the release profile stored in the electronic memory, which causes the electronic disperser to selectively change a dispersion of the taggant over time. - View Dependent Claims (15, 16, 17, 18, 19)

20. A taggant emission device, comprising:
-
a taggant reservoir configured to hold a supply of taggant and to permit only selective release of the taggant; an electronic disperser, configured to receive taggant from the taggant reservoir and to selectively disperse the taggant into an environment; an electronic control, configured to receive information defining a release profile comprising information defining a change in a rate of dispersion of the taggant from the reservoir over time by the electronic disperser, an activation state, and a deactivation state, and to operate the electronic disperser according to the release profile after initiation of the activation state and before initiation of the deactivation state; and a battery configured to power the electronic disperser and the electronic control.
