Abstract: A multi-bit test value is loaded into a built-in latch of the IC component, and a pad of the component is selected for testing. A number of different sequences of test values are automatically generated, based on the stored test value, without scanning-in additional multi-bit values into the latch. A signal that is based on the different sequences of test values is driven into the selected pad and looped back. A difference between the test values and the looped back version of the test values is determined, while automatically adjusting driver and/or receiver characteristics to determine a margin of operation of on-chip I/O buffering for the selected pad.

Abstract: A built-in self test (BIST) unit, of a primary integrated circuit (IC) component of a computer system, is programmed or hardwired with a test pattern. The test pattern is launched in multiple test cycles, to test an interconnect bus of the computer system or perform a device validation test of the component. A pin assignment of the pattern is automatically changed after each test cycle, without requiring re-programming of the BIST unit to do so.

Abstract: A reversing Gravity Fed Orbital Ride "GFOR" (10) produces a repeating, descending and ascending orbital rotation, influenced by the tug of gravity. A plurality of variably inclining and declining paths, defined in a central column (12). A passenger carriage (14) supports seats (48) and guides (22), that interlock with the closed loop paths. Passengers are elevated to an Event Horizon (42) by rotating column (12), while simultaneously inhibiting the rotation of carriage (14). Passengers are driven along a descending orbital course, after reaching the Event Horizon. Thus, passengers can experience an intense centrifugal G-Force sensation and/or weightlessness. When maximum rotational velocity is obtained, a reverse in the vertical direction sends the passengers in an orbital ascent, that slows to a brief stop, reverses it's rotational direction and begins another descent. This repeats until built momentum is spent.

Abstract: A number of detection circuits, one for each source of control signal set inputs, and a high speed resolution circuit, are provided for resolving multiple control signal inputs into a single stable, predictable, and useful output signal. The detection circuits detect active control signals in the various control signal set inputs, and generate detected signals. The high speed state resolution circuit generates an output signal, conditionally changing the output state based on the detected signals and the current state being output. When deciding whether to change the output state, the high speed resolution circuit considers only the detected signals applicable to the current output state and responds accordingly, ignoring all other detected signals that are not applicable. The detection circuits and the resolution circuit are coordinated in timings, ensuring proper resolution.
