Defence and Security

Our company has delivered services and development projects to the Swedish Defence in air-, navy- and land based applications, since the start in 1985. We have extensive experience in design against MIL standards. We are also used to trade compliance with the Wassenaar Arrangement and the Internation Trade in Arms, ITAR regulation.

    Flex-rigid PCB

    A circuit board for evaluation of IR sensors, previously developed by NOW, was redesigned into a flex-rigid PCB. The board consists of five rigid parts, with flexes in between. The board has sensitive analogue parts that receive two channels of data from the IR sensor. The data is converted to 16-bit digital values that are sent to an Altera FPGA, which sends the data to the host computer over an LVDS channel.

    Video distribution with GigE Vision

    NOW has systematized and developed a family of printed circuit boards that distribute video over the Ethernet standard GigE Vision. The video is sent in uncompressed format and can be sent from the transmitter to a receiver or from a transmitter to multiple receivers (multicast).
    Three boards have been developed with this video platform basis:

    • Conversion of SDI (serial video) to GigE Vision
    • Conversion from GigE Vision to DVI/HDMI and GigE Vision
    • Conversion from GigE Vision to analog video

    Video processing on the boards:

    • Graphic generating and overlay with real-time requirements and high performance
    • Rotation, scaling, interlacing and deinterlacing, etc.

    The boards are FPGA-based and can be easily adapted to other video standards and formats.

    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.

    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.
