Abstract: Shear-horizontal surface acoustic wave sensors with micro-cavities in the delay paths were studied using finite element methods. The microcavity devices are SAW delay path devices that have the delay path etched with square patterns at various wavelength dimensions and varying depths to increase the dispersion and bulk to surface wave conversion. Additionally the microcavities are filed with polystyrene to act as an inhomogeneous waveguide for further entrapment of wave energy near the device surface. The effects of micro-cavities and grooves on SAW propagation show significantly greater energy transmission than the other structures presented traditional sensors.

Abstract: A projectile includes a leading part formed by a tip and a tip base that form a first annular shoulder where they meet. A trailing part of the projectile is formed by a base having a frusto-conical trailing end and a cylindrical leading end of truncate extent that forms a tail drive. A second annular shoulder is formed where a cylindrical rod meets the tail drive. A flat trailing end of the tip base and a flat leading end of the cylindrical rod abut one another when the projectile is assembled. A cylindrical interface has a leading extent abutting the first annular shoulder and a trailing end abutting the second annular shoulder. The tail drive and the trailing extent of the cylindrical interface are the only parts of the projectile that engage gun barrel rifling when the projectile is positioned in a gun barrel.

Abstract: A hydrogen storage system using a coiled nano-foil hydride and methods for forming the hydrogen absorbing nano-foil coil without backing materials. Intercalation of hydrogen in metal hydrides allows for large amounts of hydrogen to be stored at atmospheric temperatures and pressures. Nano-films provide a large surface area for storage of hydrogen. Excessive heating of the system is avoided by use of a modified magnetron source, and the deposition rate is increased by employing stronger magnetic fields. The foil formed is capable of storage and of mechanical self-support without breakage and expansion up to 20% of its initial volume.

A second, inner cannula is placed within the outer cannula and attached thereto by a plurality of substantially elastic strands. The strands center the inner cannula while allowing it to be manipulated in any direction.

Abstract: A board game incorporating multiple paths of travel which traverse a plurality of elevations with moveable obstacles that change the paths of travel. The moveable obstacles may be transferrable game face members containing moveable structures; such as stairs; bridges and moveable-walls which cut-off some available paths while opening others. Additional obstacles include tunnels, spinning indicators determining the path of travel, vertical obstacles, rotating vehicles, rotating hidden compartments, and linearly sliding vehicles. Through strategic use of the obstacles; players can facilitate their own movement through the game while impeding that of their opponents.

Abstract: Activation of electrogenic pump molecules can be realized by a dynamic entrainment procedure which includes two steps: synchronization of individual pump molecules to work at the same pumping pace, and gradual modulation of the synchronization frequency. Na/K pump molecules were used as an example in a physiological operating mode by applying the concept of an electronic synchrotron to the biological system. It was shown that individual Na/K pump molecules can be synchronized by a well designed oscillating electric field. The synchronized pump currents show separated inward and outward pump currents and a magnitude ratio of 3:2 reflecting stoichiometric number of the pump molecules.

Abstract: A device for the precise and accurate potentiometric pH measurements in situ. Embodiments of a potentiometric device according to the invention consist of one or more glass pH-sensitive electrodes connected to a potentiometer. A key feature of the device is that, rather than being calibrated conventionally with buffers, it can be calibrated with an in situ device that measures pH spectrophotometrically. Spectrophotometric pH measurements obtained via sulfonephthalein absorbance measurements are inherently calibrated (do not require buffers). Thus, devices according to the invention allow for continuous potentiometric pH measurements with occasional spectrophotometric calibrations. The spectrophotometric calibration device consists of a spectrophotometer with associated pumps for combining a sulfonephthalein pH indicator with the aqueous medium whose pH is to be measured.

Abstract: In accordance with the present invention, a system and method that exploits the efficiency of the spectrum utilization is provided. The proposed technique, which is referred to as dispersed spectrum utilization, is based on the idea of transmitting the information over multiple dispersed bands in contrast to the current wireless communication systems which transmit the signal over a single band. A cognitive radio transceiver is developed for the implementation of this dispersed spectrum utilization technique.
