Software aids board inspection

Click here to enlarge image

RTI version 4.9 software runs on the SV-7550 automated optical inspection system and the SVX-2000 automated optical and x-ray inspection system. Its algorithms and autoreset option improve the yield of printed-circuit-board assembly with a 50% reduction in setup time, 15% fewer false calls, and 10% reduction in inspection cycle time. Other features include inspection parameter traceability, improved CAD import, an image package library, optical character recognition, resistor color-band confirmation, gap-measurement inspection, and links to inspection algorithms. Existing algorithms are updated to include object matching and graphical inspection parameter statistics.

Frame grabber has video processor

Click here to enlarge image

FlashBus Prism bus-mastering frame grabber uses a Philips TriMedia very-long-instruction-word video processor and a 16-Mbye SDRAM to provide interpolated scaling, hardware overlay, real-time video rotation, and video output functions. With multiple composite, S-Video, and component video inputs, video outputs, and video capture, it handles image analysis, medical and scientific imaging, and video surveillance. The board captures images from up to four RGB or YCrCb component, eight S-Video, or 16 composite/monochrome video sources in NTSC or PAL format. Video can be captured and stored in either square-pixel or CCIR-601 resolutions and can be scaled to an arbitrary size. Switching of up to 20 images/s between camera inputs is available. Software support includes a software developer kit and DLLs for Microsoft Windows 9x/ME/NT 4.0/2000/XP operating systems. Source-code samples are included in both Visual C and Visual BASIC.

Flexlife-10 cables are rated at 10 million cycles of flexing, bending, and twisting motion while conducting power and data signals on the factory floor. They use oil-, water-, and abrasion-resistant thermoplastic elastomer and polyurethane jackets, Teflon flex facilitators, and up to 19 custom alloy conductors. UL-recognized and CSA-approved, these cables are available as molded cordsets or spooled cable in 30-, 100-, or 200-m lengths with standard connectors. Operating temperatures range from –40°C to 105°C.

Board compresses video FalconEye PCI bus wavelet-compression board can switch video sources and digitize, compress, and store compressed video data to either fixed or removable media. Compressed data can be transmitted to a local/remote location through a LAN, WAN, or Internet connection. The board supports color (NTSC/PAL/Y-C) or monochrome (RS-170/CCIR) video sources. On-board compression hardware can process 60 fields/s of CCIR601 digital video. Up to 16 event inputs and two strobe outputs are accommodated, and inputs are programmable to generate alarm signals. Videos from up to 16 cameras are selectable for recording/transmission. Up to eight video sources are supported on an MDR 36-pin connector. Active channels and frame rate of each channel are software-programmable. A supplied utility operates Windows 98/NT/2000/XP.

Mirrors work off-axis Parabolic metal mirrors can direct and focus incident collimated light at 30°, 60°, or 90° off-axis. They are sections of a parabola form and can focus the light to a spot that is more accessible to users than an on-axis focal spot. The mirrors are typically used as collimators in Schlierien systems, MTF systems, and laser-beam expanders. The parabolic mirrors have diameters of either 25.4 or 50.8 mm and effective focal lengths ranging from about 25 to more than 150 mm. The quarter-wave aluminum 6061-T6 substrate mirrors come with protected aluminum coatings for visible applications or protected gold coatings for use in forward-looking infrared test systems. Each mirror has a 6-32 TPI tapped hole for accurate mounting.
