Abstract: A method and apparatus for detecting signals transmitted via a power line to a node which have a source address portion equal to the predetermined address of an electrical metering device, but which were not transmitted by the metering device. Each electrical metering device of a power line communications system has a predetermined address and may monitor the source address portions of signals transmitted via the power lines. The electrical metering device thus detects or flags a power line signal if the source address portion of the transmitted signal matches the predetermined address of the electrical metering device. The electrical metering device may also count the signals having source address portions which match the predetermined address of the electrical metering device.

Abstract: A method and apparatus for determining the progress of a superplastic formation process that uses cumulative gas-mass outflow from a forming part being formed from generally one or more sheets of superplastically formable material, a process that may include selective diffusion bonding of the sheets together. The method includes using the expected initial conditions of the process to determine the gas-mass cumulative exhaust at room temperature and pressure. The method is advantageous over inlet measuring methods where high pressure gas must be measured and any small hole in the system results in large errors.

Abstract: A low-density, porous material is prepared by mixing together microballoons and an oligomeric precursor to a polyesterimide polymer. The oligomeric precursor has an initial viscosity sufficiently low that it can flow and wet the microballoons when first heated to a polymerization processing temperature, and thereafter polymerize. Fibers may be controllably incorporated into the material during processing to impart specific properties, and air may be controllably incorporated into the material during processing to further decrease its density.

Abstract: The calibration standard has artificial defects of a predetermined uniform size disposed on selected areas of a substrate. The artificial defects are randomly spaced within the selected area and of a sufficient density as to be visually discernable through a CRT display or other output device. The selected areas in which the artificial defects are disposed are formed by positioning a mask above the substrate. The open areas of the mask correspond to the selected areas on which the artificial defects are disposed. The form of these open areas may correspond to a character representing the predetermined size of the artificial defect. If this is the case, the operator can determine the size of the artificial defects on a substrate without reference to any external source.

Abstract: A method of fabricating a structural panel having a predetermined shape features forming an inflatable envelope assembly from at least a pair of superplastically formed and diffusion bonded metallic core sheets. The inflatable envelope assembly can be disposed between first and second metallic face sheets which are generally superplastically formed into the predetermined shape prior to being assembled. Thereafter, the assembled face sheets and the inflatable envelope assembly can be superplastically formed and diffusion bonded to form an integral structure, such as structural panel having a compound curvature. Alternatively, the inflatable envelope assembly can be disposed between a pair of reinforced titanium composite sheets. The reinforced titanium composite sheets can also be joined to adjacent face sheets, such as by welding or diffusion bonding, such that an integral structural panel having the predetermined shape can be readily fabricated.
