Abstract: A scan path debugger isolates and identifies hardware and software faults in a computer system containing scan path logic. A user can readily define what information is to be examined and in what format. The user can toggle between displaying information in data-aligned format or time-aligned format. The user may temporarily suspend control of the scan path debugger to allow the system to be controlled temporarily by a different, unrelated program. The user can check the operation of the system under different microcode files. The user can also save the complete logic state of the system under test, execute one or more scan path debugger instructions while observing the results, restore the saved state, execute the same or different instructions, and observe the results.

Abstract: There is disclosed a method of making a fork for a fork lift vehicle, which fork is formed with an integral head, created by forging the same, into a hooked shape form, the rest of the fork being of generally conventional configuration, the fork further including a mechanism to effect latching of the same in position for use made possible by the method and ultimate form of the fork head and to make positive the positioning and release of the fork for movement into various transverse positions with respect to the vehicle.
