Abstract: Images may be stored on film or on one of the TV/video standards. Film comprises a sequence of frames each of which corresponds to the same point in time. Video, however, comprises a sequence of frames each comprising an interlace of 2 fields which successively scan the image and thus each field does not correspond to the same point in time.Due to these inherent differences, when converting from film to one of the TV standards and between the TV standards when at least part of the image originates on film, distortions are introduced particularly when there are any objects moving in the image.The present invention includes a vector motion estimator (10) providing motion vectors which are indicative of any objects moving and are used to manipulate the standards converter (8) so as to accommodate for the moving objects.

Abstract: An automatic test equipment for the functional testing of electrical printed circuit board assemblies is constructed as the combination of a programmable controller based upon a microcomputer and selected interface modules which can be plugged into the controller system backplane in any of a number of module interconnection locations and in any combination of module types with the controller being adapted to interrogate the modules as to their type and location and organize its routines accordingly. The controller has an advantageous bus structure for resource sharing within the equipment, and provides facilities for various forms of input/output modules as well as for analog stimulus/response modules, programmable waveform generator modules, signature analysis and frequency measurement modules, real time emulation modules, etc., and for the connection of computer standard utilities such as keyboard, light-pen graphics, printer, etc.

Abstract: An in-circuit testing apparatus (manufacturing defects analyzer) for the determination of manufacturing defects in an electrical circuit board such as short circuits, tracking faults, mininserted omitted and out-of tolerance components etc., and not for effecting full functional testing of the circuit board, comprises an array of bidirectionally current conducting analog switching networks each of which defines a test point for connection to a node of a circuit board and connectable, under software control of the respective switchng network, either to a stimulus source or to a reference (e.g. ground) potential and simultaneously also to an input of a measurement facility. A resistor, capacitor, inductor or other circuit component can be connected between the test points defined by two of the switching networks and can thus be subjected to an appropriate stimulus and its response measured and analyzed for determining the viability of the respective component.
