Abstract: A piling anti-lift system utilizes a heat trace cable secured around a piling and extending above and below the water level of the surrounding water. An annular space is formed between the piling anti-lift system. The heated piling anti-lift system prevents the water in the annular space from freezing and thereby prevents the piling from being subject to uplifting or heaving that results from the rising tide of surrounding frozen waters. In the event of extreme water temperatures and the freezing of the water in the formed annular space, the piling anti-lift system keeps the piling independent of the frozen surrounding water. In this situation, the piling anti-lift system will break free from the frozen water in the annular area and rise with the rising tide waters, thus continuing to keep the piling independent from the rising frozen tide waters.
Abstract: There is provided a system and method for statistical timing analysis of an electrical circuit. The system includes at least one parameter input, a statistical static timing analyzer, and at least one output. The at least one parameter input is for receiving parameters of the electrical circuit. At least one of the parameters has at least one of a non-Gaussian probability distribution and a non-linear delay effect. The statistical static timing analyzer is for calculating at least one of a signal arrival time and a signal required time for the electrical circuit using the at least one parameter. The at least one output is for outputting the at least one of the signal arrival time and the signal required time.

Abstract: A method and a system for automated verification and status identification (context) of objects using data about the objects captured via computer-enabled sensing elements are provided. The object may include goods tagged with electronic identifiers. The objects are shipped from one location to another, and identified via their electronic identifiers. The objects are scanned at the various locations by a number of sensing devices. The outcome of sensing is then compared with stored information describing the object and pointed at by their electronic identifier. The comparison is used to automatically verify that the scanned object is as identified and evaluate its condition.

Abstract: A method for fabricating a semiconductor substrate includes epitaxially growing an elemental semiconductor layer on a compound semiconductor substrate. An insulating layer is deposited on top of the elemental semiconductor layer, so as to form a first substrate. The first substrate is wafer bonded onto a monocrystalline Si substrate, such that the insulating layer bonds with the monocrystalline Si substrate. A semiconductor device includes a monocrystalline substrate, and a dielectric layer formed on the monocrystalline substrate. A semiconductor compound is formed on the dielectric layer and an elemental semiconductor material formed in proximity of the semiconductor compound and lattice-matched to the semiconductor compound.

Abstract: A method for replacing cache lines in a computer system having a non-uniform set associative cache memory is disclosed. The method incorporates access latency as an additional factor into the existing ranking guidelines for replacement of a line, the higher the rank of the line the sooner that it is likely to be evicted from the cache. Among a group of highest ranking cache lines in a cache set, the cache line chosen to be replaced is one that provides the lowest latency access to a requesting entity, such as a processor. The distance separating the requesting entity from the memory partition where the cache line is stored most affects access latency.

Abstract: Selection criteria for dyes that predicts efficiency and performance for plastics welding. A first stage quantitative calculation screens dyes that possess an absorption band that can be matched to a laser that is suitable for plastic welding. It also identifies absorption troughs in the visible spectrum and establishes relationships between the relative optical densities of the absorption band and trough. A second stage quantitative calculation screens dyes for their contribution to the transparency of the substrate. By combining these two stages, the usefulness of a candidate dye can be quickly, easily and inexpensively determined.

Abstract: A random access memory includes a memory cell having an access device. The access device is switched on or off in accordance with a signal on a wordline to conduct a memory operation through the access device. A logic circuit is coupled to the wordline to delay or gate the wordline signal until an enable signal has arrived at the logic circuit. The access device improves stability and eliminates early read problems.

Abstract: An object producing an acoustic wave is located and identified by passive detection of the acoustic wave. The acoustic wave is defined by different sensors in an array having a plurality of passive acoustic detectors. The sensors produce signals in response to the detection of the acoustic wave. A wavelet derived from an acoustic wave of a known form with which each of the at least three signals correlates, is determined. Time difference of arrival measurements between the at least three signals using correlation intensity with the wavelet is used to performed acoustic reciprocity from each of the different detectors. The result of the acoustic reciprocity is a hemisphere centered around each of the different sensors. The hemispheres produced by the acoustic reciprocity are examiner to determine an intersection point of at least three hemispheres. The size of the hemispheres is increased according to the velocity of the acoustic wave and pre-determined intervals until an intersection point is found.

Abstract: A condenser microphone and a method of mounting a condenser microphone on a main PCB are provided. The method includes assembling the condenser microphone by assembling elements of the condenser microphone such that a vibration plate including a diaphragm and a backplate is directed toward an opened surface of a casing of the condenser microphone. The casing has a closed bottom surface and an opened surface opposite to the closed bottom surface. A PCB includes a sound hole. The assembled condenser microphone is positioned on a main PCB such that the sound hole of the PCB is aligned in accordance with a through hole formed in the main PCB. According to the present invention, if necessary, the main PCB can be mounted such that its elements surface is directed toward an inside of an electronic product, thereby maintaining good sound quality due to a short delivery path of sound waves.
