Abstract: Several audio signal processing techniques may be used in various combinatio ns to improve the quality of audio represented by an information stream formed by splice editing two or more other information streams. The techniques are particularly useful in applications that bundle audio information with video information. In one technique, gain - control words conveyed with the audio information stream are used to interpolate playback sound levels across a splice. In another technique, special filterbanks or forms of TDAC transforms are used to suppress abasing artifacts on either side of a splice. In yet anothe r technique, special filterbanks or crossfade window functions are used to optimize the attenuation of spectral splatter created at a splice. I n a further technique, audio sample rates are converted according to frame lengths and rates to allow audio information to be bundled with, fo r example, video information. In yet a further technique, audio blocks are dynamically aligned so that proper synchronization can be maintained across a splice. An example for 48 kHz audio with NTSC video is discussed.

Abstract: A fluid flow control valve having a cam disposed near an opening of a fuel passage. The cam is operable to be rotated about a shaft by the action of a float. As a fluid level in a tank changes, the cam rotates from an open position remote from the opening to a closed position (as illustrated) proximate the opening. A gap remains between the cam and the opening, thereby allowing the fluid level to be drawn down to the bottom of opening. Float has a generally wedge shaped cross-section to minimize the effect of wave action in the fluid.

Abstract: A method for spatially controlling the period and amplitude of Bragg filters in an optical medium having a longitudinal axis that is sensitive to at least some wavelength of electromagnetic radiation. A phase mask of period A is laid close to the optical medium at an angle a with respect to the longitudinal axis of the optical medium. A  single beam of electromagnetic radiation is directed at an incidence angle ~ with respect to normal incidence on the phase mask so that the radiation is diffracted, resulting in an interference pattern having a period P impinged into the optical medium so that the period P of the interference pattern may be altered by changing the incidence angle ~ or the angle .alpha.. This method is simpler, more flexible and more suitable for mass production than existing methods.

Granted: 2009-04-14
Abstract: A wipe support device and a method for supporting exposed pipes on flat roofs. The pipe support device includes a body having a base portion with a lower pad-receiving area. An upwardly extending support portion has an upper surface for vertically supporting the pipes without restraining them from horizontal movement. A pad is adapted to engage the pad receiving area to engage and conform to the irregular surface of the roof. The pipes rest on but are not rigidly connected to the upper surface of the support portion such that the pipes slide on the upper surface during movement due to thermal expansion and contraction of the pipes. Deformation of the pad about the irregular surface under weight of the pipes anchors the pipe support device in a desired position on the roof by slightly compressing the pad without requiring permanent mounting to the roof and while protecting the membrane from penetration by the gravel due to the weight of the pipes resting thereon. Multiple longitudinally adjacent pipe support devices are adapted to be interconnectable to form elongate rooftop pipe support assemblies of a desired length to support multiple pipes.

Title: Mast and method of manufacturing a structural member for a boat
Inventor: COUNTOURIS PAUL
IPC: B32B27/04
Filed: 2003-07-21
Granted: 2007-07-10
Abstract: A mast for a sailboat and a method of manufacturing the mast or other structural member for a boat, which is produced in a female mold. Any augmentation of the deflection resistance of the structural member is provided by fabric-resin fabric added to the interior surfaces of the until the desired deflection characteristics are achieved. The mast is formed from at least two parts, which in the preferred embodiment are joined together by seam anchor strips, preferably in conjunction with a fabric-resin insert that overlays the interior of the seam strip and extends over a portion of the mast half body. If additional fabric-resin fabric is required after testing, it can be added to the inside surfaces of the mast parts before the trailing seam is sealed. The structural member of the invention accordingly requires no external finishing, and the appearance, taper and aerodynamic characteristics thereof are fully determined by the mold, resulting in a consistently accurate, uniform and aesthetically pleasing product that is considerably less expensive to produce than a conventional fabric-resin structural member and substantially stronger than a comparable aluminum structural member.
