The invention consists of a uniquely punched or printed key, often in the form of a card, that is used to identify and authenticate a user during online transactions. The computer randomly generates an array of characters, such as numbers, letters or symbols, which is displayed to the user, e.g., on a computer monitor, or printed, such as in matrix format. When held over the displayed matrix, the key allows the user to view only certain portions of the matrix, which portions together form the user's one-time-password, which is unique for each authentication transaction. The user is then authenticated by utilizing both the actual key and a password or personal identification number. This two-pronged requirement for authentication insures the high security level provided by the system.

A hydrokinetic water turbine system includes two turbine assemblies each having a frame structure, a horizontally-disposed shaft supported by the frame structure, and a rotor secured to the shaft. The rotor has a plurality of spaced-apart blades so that the flowing stream of water revolves the rotor. The blades are filled with a foam material to reduce weight and increase buoyancy. The frame structure is an open frame structure and includes frame members adapted to reduce a coefficient of drag of the frame structure. The frame members are filled with a foam material to reduce weight and increase buoyancy. The two turbine assemblies are secured side by side with shafts coaxial and the rotors rotating in opposite directions. The shafts can drive electric generators located out of the water or under the water. The underwater generators can be direct drive, low speed, high output generators.

A system for monitoring and controlling boundary scan chains in real time that does not require the use of test vectors or test executives. The system automatically builds virtual Devices Under Test (DUT's) from user provided Boundary Scan Description Language (BSDL) files and displays them on the computer display. The virtual devices are connected to a port on the computer and the scan button is pressed to invoke a boundary scan. The results are displayed as color coded “pins” on a computer display to indicate if the pin is at a logic high, a logic low, or is toggling. Logic values may be forced on the pin via a point-and-click graphical user interface, again bypassing the need for test vectors. Graphical indicators and controls are provided by the system to help simplify monitoring and controlling of the boundary scan chain.

An inflator (10) comprising a housing (12) having an interior and a plurality of gas exit orifices (14) formed therealong. A gas source material (20) is positioned in the housing interior and is enclosed in a pliable, rupturable substantially gas-and-moisture-impermeable container (24). The gas source (20) is a material (for example, hydrogen peroxide) adapted to undergo decomposition to form at least one gaseous decomposition product comprising an inflation gas. A reactant material (22) is also positioned in the interior of the housing (12). The reactant (22) is a material (such as a catalyst) adapted to react with the gas source material to produce decomposition of the gas source material (20). An enclosure (28) is positioned within the housing (12) to form a cavity (30) between an outer wall of the housing (12) and the enclosure (28). The reactant material (22) is positioned in the cavity (30). A plurality of orifices (34) formed along the enclosure (28) enables fluid communication between the interior of the enclosure (28) and the cavity (30). The container (24) is positioned in the enclosure (28). A resilient, expandable bladder (42) is also positioned in the enclosure (28). A propellant (44) is provided within the bladder (42) for generation of combustion gases upon ignition of the propellant (44), to produce expansion of the bladder (42). Upon ignition of the propellant (44), combustion gases expand the bladder (42), forcing a portion of the container (24) into the enclosure orifices (34), thereby stressing and rupturing the portions of the container (24) in the orifices (34) and releasing the hydrogen peroxide (20) to flow through the orifices (34) into the cavity (30), where it reacts with the catalyst (22) to produce inflation gas.

A lock bolt is engages with a recess formed on the surface of the steering shaft. In a locked position, the lock bolt engages the recess of the steering shaft. In an unlocked position, the lock bolt is withdrawn and disengaged from the recess. When the ignition key is turned to start the automobile, the lock bolt disengages the steering shaft. When the ignition key is turned to stop the automobile engine from idling, the lock bolt engages the steering shaft.

A stable personal lubricant composition comprising xylitol and excluding glycerin and parabens is provided. In one embodiment, the composition comprises from about 1% to about 15% by weight xylitol; from about 10% to about 35% by weight butylene glycol; from about 5% to about 20% by weight propylene glycol;

from about 0.1% to about 1.0% by weight polyquaternium; and from about 50% to about 70% by weight water. Also provided are methods of making and using the personal lubricant compositions comprising xylitol. Packaged kits of the compositions and articles of manufacture including the personal lubricant compositions comprising xylitol also are provided.
