Abstract: A method and system generates a building design and a three-dimensional image thereof. First building information comprising a length, width, total height and wall height of a building is received via a first graphical user interface. If the length, width, total height, wall height, and a selectable building shape yield a valid set of building parameters, a design of said building is generated at a first software module, which is configured to generate the design, including wall portions and a roof portion, using minimum information consisting of the length, width, total height, wall height, and selectable building shape. A first image and a structural analysis of the design are generated. A second software module generates a second three-dimensional image of the building, which is different from the first image. A second graphical user interface permits a user to modify the second image to include predefined building elements.

Abstract: A video camera system has a modulation transfer function (MTF). Video image data are stored in frame grabbers and converted in a digital signal processor from the image domain to the spatial domain by a two-dimensional digital Fourier transform. The spatial data are filtered by a two-dimensional aperture correction filter that has an MTF inverse to the uncorrected system MTF. The filtered spatical data are converted back into the image domain by a two-dimensional inverse digital Fourier transform. The two-dimensional digital aperture correction filter is stored in the form of software in the digital signal processor.

Abstract: The gating circuit includes a low voltage section and a high voltage section with a fast and a slow switch in the high voltage section for providing the gating pulses to the photocathode (PC) of the image intensifier. A high voltage isolated DC/DC power supply referenced to the MCPin terminal of the integral wrap around power supply of the image intensifier provides, to the fast and slow switches, positive and negative potentials referenced to MCPin. The negative potential is sufficient to turn the PC on and the positive potential is sufficient to turn the PC off and to clear burned in PC images. The high voltage isolated power supply provides high voltage isolation between the low voltage section and the reference input and outputs thereof in the high voltage section. A driver included in the high voltage section for driving the fast switch receives operating potentials from a low voltage isolated DC/DC power supply referenced to the high voltage supply.
