    Abstract: A fastener shield for use in a fluid flow path within a gas turbine engine for reducing fluid drag and heating generated by fluid flow over a plurality of circumferentially spaced fasteners. The fastener shield has a radially-extending, downstream-facing mounting flange with a plurality of circumferentially spaced bolt holes positioned to receive respective engine mounting bolts therethrough and to attach the mounting flange to elements of the turbine engine. A curved, upstream-facing fastener shield cover is positioned in spaced-apart relation to the mounting flange for at least partially covering and separating an exposed, upstream-facing portion of the bolts from the fluid flow to thereby reduce drag and consequent heating of the bolts.

    Abstract: A circuit board router (10) and method thereof. De-paneling of printed circuit boards (62) off a panel 860) is efficiently increased by a router (40) which is positioned at a location above the panel (60). A fixture positions the panel 860) below the router (40) on a base (16). A controller (64) activates a first drive mechanism (20), a second drive mechanism (26), and a third drive mechanism (32) to guide an X-arm (18), a Y-arm (24) and a Z-arm (10), respectively. The router (40), located on the Z-arm (30), moves downward to engage a router bit (42) to the panel (60) to depanel the printed circuit board (62) from the panel. A fixture chip (72), which has a preprogrammed pattern of the panel (60), is embedded inside the fixture (58). A radio frequency transmitter (80) transmits the pattern to a radio frequency receiver (82) that relays the pattern to the controller (64).

    Abstract: A system and method for nondestructive automated headspace analysis. The system includes a container conveyor that conveys a plurality of generally optically transparent sealed test containers through a pre-inspection region, an inspection region and a post-inspection region of the container conveyor, and that conveys at least one sealed reference container, through the inspection region. Also included is a zone including a laser emitter and a sensor located in the inspection region and arranged such that the laser source emits a laser beam such that it intersects with a container movement path. The conveyor alternatingly conveys test containers and reference containers through the zone.

    Abstract: The invention is a novel method and transmission system for mitigating the adverse effects of amateur (HAM) radio interference on digital signals transmitted across a twisted pair and reducing the interference caused by the digital signals to amateur radio communications. At the heart of the invention is strategical placement of the frequency spectrum of the transmitted signal relative to the center frequency of the HAM bands. In particular, the signal spectrum is permitted to straddle one or more HAM bands, which permits the transport of high data rates with a single carrier. At the transmitter, the signal is filtered with a real-valued symmetric baseband filter in order to remove signal content in the HAM bands. At the receiver, the signal undergoes adaptive interference cancellation, followed by processing through a decision feedback equalizer. In some cases, the signal is filtered at baseband with a real-valued filter to remove interference in the HAM bands. In the context of a telecommunications access system, the inventive technique can be applied to either or both directions of traffic flow, i.e., downstream and upstream, and multiple carriers can be added to increase capacity in any given direction.

    Abstract: An automated apparatus for orienting truss plates, and in particular truss plates, such as those greater than 6 inches in width, that are typically formed from a single sheet of steel, comprises: a generally horizontally-disposed platform shelf; first and second receiving channels; a sweeper block; and a reciprocal movement unit for reciprocally moving the sweeper block. The platform shelf, which is positioned to receive truss plates from a truss plate forming unit, has an upper face and a pair of opposed lateral edges. The receiving channels are positioned laterally of a respective one of the platform shelf lateral edges and below its upper face. Each of the receiving channels is sized and configured such that a truss plate falling from the upper face and received therein takes and maintains an orientation in which the backing member of the truss plate is generally upright. The sweeper block is positioned above the upper face. The reciprocal movement means moves the sweeper block transversely between a first position above the first receiving channel and a second position above the second receiving channel. The reciprocal movement means is configured so that the sweeper block passes over the upper face while moving between the first and second positions. The sweeper block is deployed at a height such that it contacts a truss plate positioned on the upper face and sweeps the truss plate over one of the lateral edges into one of the receiving channels. This action is repeated as the sweeper block is moved over the other receiving channel; in doing so, it sweeps another truss plate positioned on the upper face into the other receiving channel.
