Abstract:

An Identification-Friend-or-Foe System Using Variable Codes (IFF System) lizes variable codes and pre-selected encryption/decryption technology to querry potential targets as to their battlefield affiliation and also to identify itself as a friend to a potential attacker. The IFF System performs a querry by sending a narrow laser beam to the potential target which is accompanied or closely followed by a radio frequency (RF) wave modulated with encrypted identification information. If the potential target is also equipped with the IFF System and in possession of the valid code, then the received RF wave can be decrypted to reveal the potential attacker as a friend. The potential target, then, encrypts its own identification information using the same code and transmits it via RF wave to the potential attacker. Thus fratricides may be avoided.

Abstract:

An automated camera control drives a video or motion picture camera along multiple independent axes of movement to position the camera for recording an image of a field of view, typically focused upon a model or artwork in special effects motion picture photography. Key position coordinates are manually defined for specific frames of film in a film transport. The automated system generates axial coordinates at each intermediate frame and drives the camera to the intermediate positions thereby defined, as well as the several key positions defined manually. The camera is mounted upon a carriage and a model can also be mounted in relation to the camera and moved in coordinated fashion along a multiplicity of axes. The system accepts manual additions of specified key positions and position data, and the key position information can be edited or deleted. The camera can be driven through the same course of movement with exact repeatability once the specified key positions and corresponding positional data have been manually defined.
