Abstract: A method for navigating a 3D scene in a viewing area includes associating a point of interest with a reference shape, which is related to the shape of the 3D object, and displaying a scene according to a user-requested action, while keeping the point of interest within the reference shape and within the viewing area. The user-requested action may include translation, rotation, and zooming. The point of interest may include scene information such as a magnification factor, local orientation, and global orientation. The methods for performing a user-requested action in a 2D representation of a 3D object include determining a distance between a point of interest and a viewpoint; determining an amount of moveme nt from a user input; and performing the user-requested action at a rate based on the amoun t of movement from the user input multiplied by a distance factor based on the distance between the point of interest and the viewpoint. A system for displaying a 3D object includes a 2D display for displaying the 3D object and a computer operatively coupled to the 2D display, the computer having a program to display the 3D object on the 2D display, the program adapted to enable translation, zoom, and rotation of the representation while restricting a point of interest within a reference shape and within a viewing window on the 2D display.

Abstract: A discharge and transfer apparatus for adjacent separated objects, such as logs of interfolded sheets discharged from an interfolder, and for supplying the logs of sheets sequentially to downstream processing equipment, such as a packaging or wrapping mechanism for applying packaging or wrapping material about each log of sheets. The discharge and transfer apparatus includes an advancing mechanism for moving the logs of sheets in a forward direction at a location downstream of the discharge area of the interfolder, and a guide mechanism, such as a series of curved guide rails, which are operable to position the logs such that the logs are moved in a generally vertical direction toward a transfer area by operation of the advancement mechanism. At the transfer area, the logs of sheets are moved upwardly between a pair of movable discharge members, which may be in the form of facing runs of a pair of discharge belts, and the discharge belts are selectively operable to propel the uppermost log of sheets laterally in a lengthwise direction along a longitudinal axis defined by the uppermost log of sheets. The uppermost log of sheets is supplied directly to the inlet area of the downstream processing equipment.

Abstract: An ice ball launcher simulates the impact of a storm-generated hail stone falling onto a test specimen or structural component exhibit such as a roofing shingle, skylight, automobile panel, aircraft fuselage panel, aircraft wing panel and the like. The launcher includes a tripod base, a rail, a sled, an ice ball holder cup, a manually operable trigger latch assembly, an elastic band and a laser beam-aiming device. The ice ball launcher consistently and repeatably projects ice balls at a predetermined velocity and impact energy onto the component sample.

Abstract: An expanded television program delivery system is described which allows viewers to select television and audio program choices from a series of menus. The primary components of the system include an operations center, a digital cable headend, and at least one set top terminal having a remote control. The system allows for a great number of television signals to be transmitted by using digital compression techniques. A combined signal is transmitted over satellite to a cable headend, which may modify the combined signal for changes or additions in programming or menu content. The combined or modified signal is subsequently distributed to individual set top terminals in the cable network. Menus are partially stored in a set top terminal in each subscriber's home and may be reprogrammed by signals sent from the operations center or headend. Numerous types of menus may be used, incorporating information included within the video/data signal received by the set top terminal. A remote control unit with icon buttons allows a subscriber to select programs based upon a series of major menus, submenus, and during program menus. Various data gathering and analysis techniques are used to compile programs watched information that in turn is used in packaging programs, customizing menu selections, targeting advertisements, and maintaining account and billing information.

Abstract: Une architecture de base de données pour un système d'information sur la circulation aérienne comprend un gestionnaire de données avec les éléments qui suivent. Une première interface; un premier serveur de base de données raccordé au gestionnaire de données par la première interface; un coupe-feu raccordé au premier serveur de base de données; et un second serveur de base de données raccordé au premier serveur de base de données par le coupe-feu et comprenant une procédure mémorisée pour copier des données de la première base de données. Le second serveur de base de données sert aux calculs reposant sur les transactions de données tirées du premier serveur de base de données. Par conséquent, le déchargement du premier serveur de base de données s'effectue, de sorte qu'il peut être plus sensible au gestionnaire de données relativement aux changements courants. Le coupe-feu entre les deux serveurs empêche les données du premier serveur d'être corrompues par les utilisateurs du système.
