Abstract: A serpentine belt drive system (18) for an automotive vehicle comprising a drive assembly including an internal combustion engine (10) having an output shaft (14) with a driving pulley (16) thereon rotable about a driving pulley axis. A sequence of driven assemblies each has a driven pulley rotable about an axis parallel with the driving pulley axis and a serpentine belt (20) mounted in cooperating relation with the driving pulley (16) and with the driven pulleys in a sequence which corresponds with the sequence of the driven assemblies when related to the direction of movement of the belt to cause said driven pulleys to rotate in response to the rotation of the driving pulley. The sequence of driven assemblies includes an alternator assembly (26) including an alternator shaft (36) mounted for rotation about a shaft axis. A hub strucure (52) is fixedly carried by the alternator shaft (36) for rotation therewith about the shaft axis. A  spring and one-way clutch mechanism couples the alternator pulley (26) with the hub structure (52). The spring and one-way clutch mechanism (72) comprises a resilient spring member (74) separately formed from and connected in series with a one-way clutch member (76). The resilient spring member (74) is constructed and arranged to transmit the driven rotational movements of the alternator pulley (26) by the serpentine belt (20) to the hub structure (52) such that the alternator shaft (36) is rotated in the same direction as the alternator pulley (26) while being capable of instantaneous relative resilient movements in opposite directions with respect to the alternator pulley during the driven rotational movement thereof. The one-way clutch member (76) is constructed and arranged to allow the hub structure and hence the alternator shaft to rotate at a speed in excess of the rotational speed of the alternator pulley when the speed of the engine output shaft is decelerated to an extend sufficient to establish the torque between the alternator pulley (26) and the hub structure (52) at the predetermined negative level.

Abstract: Apparatus and method for detecting the presence of macro viruses within a digital computer (1). An application program (5) is associated with the digital computer (1).  A global environment (13) is associated with the application program (5). The application program (5) generates at least one local document (11). Macros contained within the global environment (13) and the local document(s) (11) are executed in a simulated manner by an emulator (15). At least one preselected decision criterion is used by a detection module (17) to declare when a macro virus is deemed to be present. Such a criterion is typically the presence of a bidirectional macro, i.e., a macro that copies from a local document (11) to the global environment (13) and vice-versa.  Macros deemed to be viruses are preferably deleted by a repair module (19). Additional deletion criteria may include the presence of macros that have the same source name or the same destination name as a bidirectional macro. In the preferred emulation steps, emulator (15) tests all of the macros associated with computer (1) in two steps. The first step assumes that the macros reside within the global environment (13), regardless of whether they reside within the global environment (13) or within a local document (11). The second step assumes that the macros reside within a local document (11), regardless of whether they reside within a local document (11) or within the global environment (13).

A contour curve generator section generates a contour curve candidate list corresponding to the list of the plurality of color projection axis candidates. The contour curve candidate list generated by the contour curve generator section 33 is displayed on a display device. Further, a user is invited to make selection by a candidate list select section 71, and the color projection axis selected by the user is sent to the contour curve generator section 33.  The contour curve generator section 33 generates a new contour curve within the update sector from the image, representative points 1 and 2, and the color projection axis.  The update sector synthesizer section 34 synthesizes the contour curve of an updated sector with a closed curve thereby to generate a new closed contour curve.
