Abstract: Apparatus, system and method for providiing tactical information. One aspect is a system and method for displaying vectors (preferably in real time) for very fast moving (VFM) elements, such as projectiles (e.g., bullets or shells), missiles, and other transient events that arise in a battlefield or civil police action. The system optically and/or acoustically collects information about the ordinance and displays vectors of otherwise unseen ordinance. One aspect is a device for collecting intelligence on and confusing enemy troops, as well as small munition deployment.

Abstract: An automated exterior building cleaning system particularly well suited for cleaning the window exteriors on a high rise building. By way of example the system is deployed on a rooftop rail system traversed by a movable platform from which a washing head is deployed over the edges of the building and lowered on cables for cleaning the window surfaces and other building elements. The system is configured for remote monitoring and control and provides a number of novel elements and safety features.
