A8E_EE-Times-Eur_2-375x10-875_A8.qxd 3/24/14 12 Video processing system supports multi-band TV/IR imaging RFEL has announced the Rapid Product Development System (RPDS) for its HALO video processing solution. The plug and play platform enables customers to input video, try out REFL’s video processing algorithms and immediately see the quality Fig. 6: High-current reference buffer. optional, as classical resolvers filter out high-frequency components exceptionally well.When combined with the AD2S1210 resolver-to-digital converter, resolvers can create a high-precision, robust control system for position and velocity measurements in motor-control applications. To achieve the best overall performance, buffer circuits are required to amplify the excitation signals and provide the drive strength required by the resolver. To complete the system, a basic input circuit can provide signal conditioning. As is the case with all mixed-signal mechatronic signal chains, care must be taken to design an accurate system that considers all error sources. With its variable resolution, reference generation, and on-chip diagnostics, the AD2S1210 provides an ideal RDC solution for resolver applications. It is available in industrial and automotive grades. Surface Mount (and Plug In) Transformers and Inductors See Pico’s full Catalog immediately www.pic o el ect r onic s.com Low Profile from .18"ht.

Designers can then select which of the various HALO form factors is most suitable for their project. In addition to real-time high definition video enhancement, HALO can also handle the camera control interface for Pan Tilt Zoom (PTZ) making it an all-in-one solution for CCTV control and image processing. State-ofthe art video processing solutions include digital stabilisation, adaptive contrast enhancement, multi-band fusion and lens distortion correction. HALO enables video analytics directly at the source. Its real-time video processing blocks condition the incoming stream and rectify many of the common shortfalls of existing video systems, including poor raw sensor imagery under very challenging lighting or atmospheric conditions. For example, a camera mounted on a moving vehicle, aircraft or even on the top of a pole will suffer from shake and vibration that makes it challenging for machine automated video processing and very tiring for a human operator to watch. HALO is available as ruggedly-housed sub-system measuring 137x105x80mm, as a PCI Express-based XMC form factor board, or as a 90x75mm System-on-Module board, equipped with an all-digital high-density connector to implement directly into sensor housings.
