Show moreA system for producing variable amplitude pneumatic pulses, such as may be used to prevent flow separation on airfoil and diffuser surfaces to control stalling, utilizes a source of pressurized air which is regulated and fed to parallel outlet lines. Each outlet line has a control valve therein attached to a controller for activation of the valves. The first parallel line leads to an actuator which supplies the pulsed air to a desired surface. The second parallel line leads to the atmosphere. By cycling the valves at about ninety degrees out of phase, pneumatic pulses of large amplitude are obtained with a simple device capable of being transported on the aircraft.

Show moreA peer-to-peer (P2P) file sharing system is provided with an enhanced search method for a client computer therein. The method includes masking at least one term in a multi-term query entered into a client computer of the P2P system to obtain a masked query and routing the masked query to a plurality of server computers. The masked query is compared to a file descriptor of server files in each of the plurality of server computers to identify a plurality of matching server files. The server computers return to the client computer as search results the file descriptor and a mathematical identifier for each of the plurality of matching server files. The server computer may return to the client computer only a subset of the plurality of the matching server files. Enhanced P2P file searching accuracy is provided.

Show moreThis invention relates to a power module for a plug-in hybrid electric vehicle including an integrated converter having a rectifier changing AC to DC, a DC/DC converter changing from a first voltage to a second voltage, and a battery storing electrical energy. The integrated converter operates in three modes 1) AC plug-in charging mode, 2) boost mode supplying power from the battery to the electrical bus and 3) buck mode supplying power from the electrical bus to the battery. The integrated converter utilizes the same single inductor during each of the three operating modes to reduce cost and weight of the system.

Show moreAn electrohydrodynamic (EHD) conduction pump is provided for pumping dielectric liquids, and a particular adaptation for mass transport of isothermal and non-isothermal single phase liquids. The EHD conduction pump does not require direct injection of electric charges into the fluid. The EHD conduction pump includes an EHD pumping section and associated connecting tubes with electrodes arranged in series in the pumping section. The electrodes are coupled to a high voltage low current dc power supply. A positive polarity dc voltage is applied to the electrodes. Various electrode configurations may be used, such as three-needle, hollow-tube, or pin-needle electrode configuration.

Show moreA bolt having a shank and integral head has a strip of photoelastic material mounted on the head for manifesting in the form of photoelastic fringes linearly related to bolt tension the bending stresses created in the head during loading of the bolt. To determine the tension in the bolt during or after loading, polarized light is directed toward the photoelastic strip and reflected light from the strip is analyzed to measure fringe order. The fringe order is related to the amount of bending stresses in the head of the bolt by a predetermined calibration curve, the bending stresses being linearly related to bolt tension.

Show moreA tutorial or diagnostic aid based on the representation and iterative interpretation of visual images is taught. A teaching or diagnostic session is created by overlaying an interpretation layer via a software application onto the visual image layer and synchronizing the two with the time code of the visual image. The interpretation layer allows the reviewer to identify image areas of interest by gesture and append comments thereto in real time; i.e. images or portions of images within the visual representation playback may be identified and labeled and have the concurrent commentary associated therewith. The comments are indexed and linked to a database of similar topics. The flow of the session is recorded to show the images, deictic gestures associated therewith, and commentary associated with the gestures, to enable subsequent users to playback a session and follow the flow of thought (i.e. image identification and commentary within the original session). Iterative sessions allow additional image identification and commentary to be accomplished. Additional database access through the index may further enhance a teaching session, or provide for research sessions and report generation.

Show moreSystems for improved vehicular movement between first and second crossing roadways. The systems employ multiple turn roadways to permit a vehicle traveling on one of the crossing roadways to appropriately turn and continuously travel onto the other of the crossing roadway. The systems are adaptable to use in conjunction with either left side of the road vehicle movement or right side of the road vehicle movement. In addition, the systems can be adapted for use in conjunction a roadway crossing whereat at least one of the roads is for forwarded vehicle movement in only one direction.

Show moreA method of controlling a DC/DC converter to regulate an output voltage from an input voltage source that varies from a fully-charged voltage to a discharged voltage. The method introduced improves the dynamic response of the converter during transients by switching between different converter topologies to spread out voltage spikes, which are an inevitable result of transients. The invention also can improve the efficiency of the DC/DC converter by replacing higher loss modes with combination modes.
