Abstract: The sequencer (14) is part of a computational system (10) which includes a computational circuit component, or processor node array (16); the sequencer, or controller component (14); and a boundary interface (34) between the computational circuit component (16) and the controller component (14). The controller component (14) provides three main functions in the system: (one) it sequences computations in a computational component (16), which includes an array of processor nodes (74, 76, 78, 80, 82, 84); (two) it provides I/O processing (20) from several disparate sources between the processor node array (16) and a host processor (12); and (three) it synchronizes data flow from a substantially asynchronous portion of the system (12) with a substantially synchronous data flow in the processor node array portion of the system (16).

Abstract: A video training device and method for enabling a student athlete to closely pattern his dynamic technique after that of a recognized master. The exemplary device includes a pair of video cameras that transmit live images of the student as seen from those directions that best represent the technique. A video overlay generator receives the live images and combines them, while still in their video signal format, with a corresponding set of self-generated template images that represent, in static outline form, the dynamic technique of the master in the desired sport situation. The combined sets of images are sent to a pair of visual monitors for simultaneous, superimposed display of each set on a respective screen. User-operated controls on the video overlay generator permit the static image on each screen to be adjusted in size, moved vertically or horizontally, or switched to a new static image representing a different sport situation.
