    摘要: Apparatus and method for testing structures by impact. The structure is struck by an impactor associated with a force transducer the output of which is related to the force which the transducer experiences on impact and encompasses a frequency range including the lowest frequencies (typically approaching zero frequency, see FIG. 3) which that force contains to any substantial degree. A test spectrum of the force including that full range of frequencies is produced by a Fourier transformer in a form suitable for automatic comparison, and is then so compared with a reference spectrum typical of impact with a reference structure, and a signal is produced indicating fit or lack of fit between the test and reference spectra.

    摘要: The present invention, provides a single BIST which can test various memories of different sizes, types and characteristics by using a state machine to select and generate all patterns required for testing all of the memories on the chip, and impressing all of the data, including expected data, and address information on all of the memories simultaneously. The BIST also generates unique (separate) control signals for the various memories and impresses these control signals on the various memories. The BIST selectively asserts the various control signals so as to apply (write) the data and to read and capture (load result) failure information only to/from those memories whose unique controls are asserted. Selective assertion of a memory's write enable signal prevents multiple writes to a location which can potentially mask cell write and leakage defects while selective assertion of a memory's load result signal is performed only when valid memory output data is expected so as not to capture false error information. The control signals instruct those memories that do not use a particular sequence of inputs or any portion of a given sequence of inputs to "ignore" such signals, thereby generating the necessary signals to form the test patterns for each and every memory, the data and address information for those patterns, the control signals to write and read each memory, and capture error information for that particular memory. Hence, a single BIST can be used to test a multiplicity of memories of different sizes and different types.

    摘要: A bow mounted vessel propulsion system is designed to exploit the characteristics of a self-producing vessel lubricating boundary layer of air or air bubbles formed during water surface interaction by the vessel's hull during vessel movement. This boundary layer of air/air bubbles will be produced at the bow of the vessel and, during forward motion, is superimposed upon the surface of the water as the vessel's hull passes over, reducing the frictional drag of the hull as it moves across and through the water. The system has a propulsion means such as a water surface-piercing propeller or water jet nozzles, which will propel the vessel forward and, at the same time, by action of propeller rotation (drawing air into and intermixing) in the water or water jet movement, will create the air bubbles which produce the hull-lubricating phenomenon. The hull is a substantially flat-bottomed planning hull with two linear rails on each lengthwise outer edge of the bottom surface of the hull. The rails extend downward into the water at a sufficient depth to be able to keep the boundary layer of air bubbles from escaping out from the sides of the hull bottom when the vessel is in forward motion.

    摘要: A redundancy system formed on a semiconductor chip is provided which includes circuits for testing a memory array to locate a faulty element therein, a register for storing an address of the faulty element and electrical fuses blown in response to binary digits of the address stored in the register upon application of an enable signal from a single input to the semiconductor chip. The enable signal passes through logic circuits on the chip such that the fuses cannot be programmed or blown unless the enable signal is present. An address decoder coupled to outputs from the fuses substitutes a redundant element for the faulty element.

    摘要: A topology for arranging a plurality of transistors between a signal source and an off-chip receiver, using a single power supply voltage. A pass through NFET has a gate controlled by a network comprised of two transistors arrayed between the power supply voltage and the drain of the NFET, which limits overshoots to the power supply voltage and reduces undershoots. Further reduction of undershoots is accomplished by an additional network of transistors, optimally including a PFET in series with the pass through NFET.

    摘要: A bow mounted gaseous fluid vessel propulsion system provides for the introduction of gaseous fluids, e.g. ambient air and/or exhaust fluid gas from the vessel's engine, into the enclosure or duct which houses or circumscribes the propeller. Air and other fluid gases are drawn down into the upper section of the enclosure or duct to allow the propeller to operate in a half submerged, or water surface-piercing condition, while the vessel is moving forward through the water. The beneficial effects of water surface-piercing propeller operation is thereby obtained within a self-contained unit which continually maintains the top of the propeller out of the water during normal forward vessel operation.
