A radiation monitoring system for detecting levels of radiation emitted from moving objects traveling at a wide range of speeds, including the high speeds normally encountered with vehicles traveling on highways, interstates, thoroughfares, railroads and conveyors. At least two and preferably three ionizing radiation detectors are employed, spaced apart in series along the direction of travel of the moving object or vehicle. The object or vehicle is monitored for radioactivity and the results are transmitted and processed at a central location. The individual results from each detector for a particular object or vehicle are summed and averaged over the number of detectors used thereby clearly distinguishing the fluctuating background radiation detected at each detector from the consistent high levels of radiation detected from those moving objects or vehicles measured emitting radiation. The results are cooperatively linked by an identification system such as a web cam or other photographic device which obtains visual identification of the objects and vehicles emitting the abnormally high levels of radiation detected.

A videoconference apparatus and method coordinates a stationary view obtained with a stationary camera to an adjustable view obtained with an adjustable camera. The stationary camera can be a web camera, while the adjustable camera can be a pan-tilt-zoom camera. As the stationary camera obtains video, faces of participants are detected, and a boundary in the view is determined to contain the detected faces. Absence and presences of motion associated with the detected face is used to verify whether a face is reliable. To then capture and output video of the participants for the videoconference, the view of the adjustable camera is adjusted to a framed view based on the determined boundary. In the end, active video captured in the framed view with the adjustable camera can be sent to a far-end for the videoconference.
