There is provided a tamper evident container seal comprising a normally transparent polymer film which can be rendered translucent by stretching and transparent by relaxing. There is also provided a polymer film useful as a seal of the same type of film which bears an image which is not readily visible when the film is relaxed, but becomes readily visible when the film is stretched.

Container having tamper evident seal and imaged polymer film useful as

A projectile is provided having contained therein a passive electromagnetically responsive device such as a tuned inductive-capacitive circuit. The circuit is preferably detected by stimulating oscillations at the resonant frequency of the circuit by a pulsed electromagnetic field. The projectiles are desirably used to enable remote tagging and detection and/or identification of objects including livestock.

Electromagnetically responsive projectile and system for detecting same

Ballistic projectile containing an antigen and method for inoculating animals comprising the non-lethal, ballistic implantation of a projectile containing antigen totally within a living animal. Following implantation, the antigen is released in situ in the animal in response to the fluids and cells of the animal body.

Ballistic inoculation of animals and projectile therefor

Ballistically implantable projectile adapted to carry biologically active materials into a living animal body and thereafter to provide sustained release of said biologically active material into said living animal body.
