Abstract: An integrated fluid flow apparatus for managing the flow of a fluid through a conduit, includes a flow sensor configured to determine a velocity of a fluid flowing through the conduit. The apparatus includes a valve assembly positioned inline with the conduit that is movable between open and closed configurations. An electromagnet is selectively energized by a power source and situated proximate the valve assembly. A closure assembly is operatively coupled to the valve assembly and is magnetically connected to the electromagnet. The closure assembly holds the valve assembly to the open configuration when also magnetically connected to the electromagnet and moves the valve assembly to the closed configuration when the magnetic coupling is released. The apparatus includes a communications module that communicate with a homeowner or resident concerning water velocity, temperature, seismic activity, that the valve has been closed, and to solicit instructions on selected actions.

Abstract: Method and system for generating electromyographic or sub-audible signals (“SAWPs”) and for transmitting and recognizing the SAWPs that represent the original words and/or phrases. The SAWPs may be generated in an environment that interferes excessively with normal speech or that requires stealth communications, and may be transmitted using encoded, enciphered or otherwise transformed signals that are less subject to signal distortion or degradation in the ambient environment.

Abstract: The method and apparatus includes a neural network for generating a model of an object in a wind tunnel from performance data on the object. The network is trained from test input signals (e.g., leading edge flap position, trailing edge flap position, angle of attack, and other geometric configurations, and power settings) and test output signals (e.g., lift, drag, pitching moment, or other performance features). In one embodiment, the neural network training method employs a modified Levenberg-Marquardt optimization technique. The model can be generated "real time" as wind tunnel testing proceeds. Once trained, the model is used to estimate performance features associated with the aircraft given geometric configuration and/or power setting input. The invention can also be applied in other similar static flow modeling applications in aerodynamics, hydrodynamics, fluid dynamics, and other such disciplines.

Abstract: A tape reel hub includes an inner ring, an outer ring and angled ribs connecting the two rings. The ribs deflect upon compression of the outer ring to prevent the transmission of this compression to the inner ring.

Abstract: An attachment for use with a tool having a cutting surface on one end of a bar consists of a collar that has an opening corresponding substantially to the cross-sectional configuration of the bar and is frictionally supported thereon in any angular or axially-orientation. The collar has a support opening which receives a cutter insert that has its inner end supported on an abutment and is releasably retained within the support opening by a recessed fastener.

Abstract: A machining tool comprising a rotatable holder, a removable, axially adjustable leading element, such as a drill bit, mounted in the holder and a throw-away cutting insert mounted in a fixed, unadjustable position on the holder to fix the position of the cutting edge on the insert axially in relation to the leading element and the holder.
