Abstract: A system for in-circuit testing of an electronic circuit device utilizes a distributed processing architecture wherein separate controllers are used to control the testing and for data collection and correlation of the collected data to the testing conditions. In a preferred embodiment, the testing is conducted by sending test vector addresses from the test controller to each of the driver/sensor boards in the testor electronics, which addresses, in turn, are used to access driver memories containing the test conditions corresponding to the test vector addresses. In the method of the present invention, the circuit containing the device is powered up and a tester coupling mechanism is connected to the terminals of the device. Determinations are made of the physical orientation of the device with respect to the tester coupling mechanism, and of whether the device terminals are in electrical contact with the tester mechanism and with the other components of the circuit. Functional testing is then performed, and failure data resulting from the test are stored and correlated to the test conditions which were applied during the functional testing.

Abstract: In an air cooled overhead valve internal combustion engine, a metal gasket plate (16) is disposed between the cylinder portion (12) and the cylinder head (14). The metal gasket plate includes apertures (98, 100) for receiving the push rods (78) therethrough and guide tabs (102, 104; 106, 108) disposed on opposite sides of the push rod for controlling lateral displace­ment of the push rods. The metal gasket plate includes adjacent annular stepped portions (97) extending alternately in opposite directions out of the plane of the gasket plate adjacent the periphery of the aperture. Cylinder head bolts (110) are received through the cylinder head and threadedly received in the cylinder portion and pass through the metal gasket plate. Dish shaped spring washers (124) are provided between the cylinder head and the underside of the head portion of the cylinder head bolts. The cylinder head bolts are tightened into the cylinder portion sufficiently to partially compress the spring washers such that the spring washers maintain substantially constant compressive force between the cylinder head and the cylinder portion on the metal gasket plate throughout thermal cycling of the engine. Leakage of the cylinder head gasket which might otherwise occur as a result of temperature induced expansion and contraction of the engine is thereby avoided.

Abstract: A system for machining a piston blank 10 to a predetermined profile includes means for rotating the blank at a predetermined speed and means for moving the tool 22 axially with reference to the blank 10. Digital processing means 70, 72 and 74 receives input data defining the required profile (or part only of the profile if the profile is symmetrical). In response to this data, to digital information on channel 20 corresponding to the instantaneous angular position of the blank 10, and to digital data on the channel 34 corresponding to the instantaneous axial position of the tool 22, processor 72 outputs digital data defining the required position of the tool 22 in the direction perpendicular to the surface of the blank 10 in order to produce the required profile. The actuator control processor 74 outputs a corresponding digital signal which, via a digital-to-analogue convertor 92, drives a tool actuator 24 so as to position the tool correspondingly. Processor 74 also receives digital tool position feedback signals on the channel 38. An adaptive   control loop 98 senses and compensates for changes in the transfer function between the input of the processor 74 and the tool 22. Sensors 40 and 44 sense dimension distortion and temperature changes, respectively, of the blank 10 and produce corresponding compensating changes in the digital output signals.

Abstract: A system and method for performing raster operations in a patch access environment utilizes two or more source patches to produce an XY shifted destination patch. Even though the present invention operates in a patch access environment, it can form a destination patch by merging groups of pixels not residing within the same patch boundries. The shifting and merging used to form the XY shifted destination patch can be done on a patch plane basis or on a patch basis. The X shifting and merging effectively combines preselected contiguous columns of contigous patches. The X shifted patches are then shifted in the Y direction to produce XY shifted patches. A line of the XY shifted patches is stored in a memory. A second, contiguous line of XY shifted patches is also stored in the memory. The stored lines of XY shifted patches are merged and merged XY shiftedpatches can be read out of the memory in a page mode fashion. Boolean or arithmetic operations can be performed between the merged XY shifted patch and preexisting data within a destination patch area so as to produce the XY shifted destination patch.
