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 moreIn one exemplary embodiment errors due to tape flutter are overcome by recording along with the analog signal clock pulses having a rate sufficient for sampling of the highest frequency component of the analog signal. Then on playback, the reproduced clock pulses control sampling and storage of samples of the reproduced analog signal. By reading out the samples from storage at a uniform clock rate, the effect of flutter on the reproduced signal is eliminated. In another example the recorded clock rate overcomes tape skew and other mechanical irregularities in recording and reproducing multiplexed analog or digital data.

Show moreInspired by a need for personal space in a fast paced, highly mobile world, the nomad project combines the mobility and strength of a pickup truck with the convenience of a small living space. By combining a work space, kitchen, sleeping area and bathroom, this project allows this compact space to allow for the comforts of a home to be available wherever a person can travel. This exploration of the duality of interior space experiments with the folding of program space from a collapsible set of planes to a space which can be used in daily life. Show less

Show moreAn apparatus and method for controlling a yaw moment of a flight vehicle, such as an aircraft. A wing structure of the flight vehicle has a first opening or actuator positioned by a first apex section of a first side of the wing, and has a second opening or actuator positioned away from or at a distance from a second apex section of a second side of the wing. The first side and the second side can each be positioned or located opposite a centerline of the wing or wing structure. A pressure source or other pressure supply device is in communication with the first opening or actuator and the second opening or actuator to which a pressurized fluid, such as air, is controlled and delivered to control or vary the yaw moment of the flight vehicle.

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. Sponsorship: Illinois Institute of Technology United States Patent Show less
