Abstract: A computer system is introduced for curve-solid classification (raycasting) of objects in constructive solid geometry (CSG) modeling to produce image representations of two-and three- dimensional objects. The system carries out curve-solid classifications in parallel and at much higher speed than a general purpose computer. It uses primitive classification processors which compute all of the (curve-line or ray) primitive (basic solid bodies: block, cylinder, etc) intersections in parallel, combine processors which are connected into a binary tree that duplicates the binary tree defining the CSG solid and computes the set operations (union, intersection and difference), and a host computer.

Abstract: A control system for an electromagnetic clutch of a motor vehicle. The idling speed of the engine is increased to provide a fast idle state when the choke valve of the engine is closed. In the fast idle state, the initial clutch current is reduced to engage the clutch on depression of an accelerator pedal, and thereafter the rate of increase of the clutch current is rapidly increased when the engine speed and throttle opening degree become large. If the accelerator pedal is depressed quickly, the clutch current is increased at a more rapid rate in accordance with the opening degree of the throttle valve so as to provide quick starting of the vehicle.
