Abstract: An imaging system includes a 3D database for storing data relating to three-dimensional site model images having a vantage point position and orientation when displayed. A 2D database stores data relating to a two-dimensional image that corresponds to the vantage point position and orientation for the three-dimensional site model image. Both the three-dimensional site model image and two-dimensional imagery are displayed typically on a common display A processor operative with the two-dimensional and three-dimensional databases and will create and display the three-dimensional site model image and two-dimensional imagery from data retrieved from the 2D and 3D databases and correlates and synchronizes the three-dimensional site model image and two-dimensional imagery to establish and maintain a spatial orientation between the images as a user interacts with the system.

Abstract: Mechanisms are known that allow receivers to control loudness of speech in broadcast signals but these mechanisms require an estimate of speech loudness be inserted into the signal. Disclosed techniques provide improved estimates of loudness. According to one implementation, an indication of the loudness of an audio signal containing speech and other types of audio material is obtained by classifying segments of audio information as either speech or non-speech. The loudness of the speech segments is estimated and this estimate is used to derive the indication of loudness. The indication of loudness maybe used to control audio signal levels so that variations in loudness of speech between different programs is reduced. A preferred method for classifying speech segments is described.

Abstract: A video surveillance system may include a geospatial model database for storing a geospatial model of a scene, at least one video surveillance camera for capturing video of a moving object within the scene, and a video surveillance display. The system may further include a video surveillance processor for georeferencing captured video of the moving object to the geospatial model, and for generating on the video surveillance display a georeferenced surveillance video comprising an insert associated with the captured video of the moving object superimposed into the scene of the geospatial model.

Abstract: A computer-implemented method for generating an image-textured digital surface model (DSM) for a geographical area of interest including both buildings and terrain may include using a computer to generate a digital elevation model (DEM) of both the buildings and terrain for the geographical area of interest. The method may further include providing a collection of optical images including oblique optical images for the geographical area of interest including both buildings and terrain. The computer may also be used to selectively superimpose oblique optical images from the collection of optical images onto the DEM of both the buildings and terrain for the geographical area of interest and to thereby generate the image-textured DSM for the geographical area of interest including both buildings and terrain.

Abstract: A method and system for tracking an object by generating GPS coordinates for the object and a bearing associated with a movement of the object. The GPS coordinates include a latitude, a longitude, and an altitude, which are processed. The GPS coordinates can be processed to correlate the altitude of the object with an identifier that identifies a level within a structure. An icon representing the object then can be accurately located in a first view of a three dimensional model. An indicator can be associated with the icon to indicate the object's level, a bearing of the object, and/or the object's GPS coordinates. The object's GPS coordinates can be compared with a second object location to determine dispatch instructions. The object can be a person, a vehicle, watercraft or an aircraft.

Abstract: A process for the manufacture of a generally toroidal or annular choke, in which a magnetic core is provided with an insulative layer, e.g., by an injection or other molding process, and divided into two parts. Each of the parts is then provided with a respective winding. The two chokes thus made can be electrically connected in series and mechanically joined to form a choke having the shape of the original core. Preferably, the original core is annular and each of the pieces is roughly semi-annular.
