    19 inch rack emulator

    NOW has developed hardware to two 19 inch racks, where the electronics emulates the functionality of another equipment. The racks are used where the real equipment not yet is available, or cannot be used for other reasons. The rack functions are used to evaluate both electronic functions and software.

    Seven PCBs in the system were developed by NOW, plus a number of internal and external cables. PCBs and other electronics were mounted in ten EMC-safe boxes/modules, where the box fronts and backsides has engraved texts for connectors, LEDs and knobs. Both racks use 230 VAC and 100 VDC, and NOW carried through a CE marking of both racks, with the help from external testing companies.

    CCD Camera

    A complete CCD camera for military use, including mechanics, electronics and software, has been developed by NOW. The camera records a 14-bit 2048×2048 video at 160 Msamples/s. A lossless image compression with a proprietary algorithm reduces the amount of data, which is then sent over a Gigabit Ethernet link to the host computer. Basic image processing and control is done in an Altera Cyclone II FPGA. The camera is of a kinematic theodolite type.

    Vision system for inspecting dashboards

    NOW has developed a vision system for inspecting dashboards. The system is built using DirectShow and Microsoft Visual Studio .NET 2003. Cameras deliver images that are handled in real time. Possible parameters to inspect are: colour, intensity, shape, symbols, segment displays, LCD displays, indicator positions and indicator needle movement. The application encapsulates a scripting language that is easily configured through a graphichal interface. Optional controls/commands are carried out in sequence. The system communicates with the client’s control system via TCP/IP.

    Video conversion equipment

    NOW has developed a video conversion equipment which performs conversions between different video formats, for a test station used to test and develop printed circuit boards for an advanced military airborn/flight display system. The system consists of a PC and up to six video conversion boards. The PC is used to control the conversion PCBs and to translate commands coming from the operator’s computer via Ethernet, into commands that can be interpreted by the conversion boards. Everything is assembled to fit in a 19″ rack. With this equipment it is possible to test video chains without having a complete system with different cameras and sensors. The equipment converts video between analog and digital video standards and can also store, load/read, and rotate images.

    Stimulus-generation equipment

    NOW has developed several generations of stimulus-generation equipment, for a test station used to test and develop printed circuit boards for an advanced military airborn/flight display systems. A system contains up to three boards of the same type, where each board has three video outputs, two analogue and one digital. The analogue outputs can be synchronized to an external sync signal. The boards are controlled via buttons on the front panel, or with commands from the control computer via GPIB, IEEE-488.2. The equipment simulates the video from cameras, IR-cameras, radar and so on, and delivers several outputs of different video standard.
