Abstract: A method of resin transfer molding uses an open base mold filled with fiberglass material and a soft tool sealed over the base mold. A vacuum is applied to a vacuum chamber that surrounds the mold and communicates with the fiberglass material through vacuum conduits. Resin is injected into the closed mold and is drawn through the fiberglass material to the edge of the mold with the assistance of the vacuum. The soft tool is preferably a flexible sheet having an edge seal to connect to the base mold and a vacuum channel with a vacuum port that surrounds the mold. The injection head releasably connects to the soft tool and preferably uses a solenoid actuated injector to supply resin to the mold. The injection head can include a self sealing device to seal the injection port and a self cleaning mechanism for flushing resin from the interior chamber of the head.

Abstract: Systems and methods are provided for conducting games or other interactions between networked computers, mobile devices, or other such client devices. Players compete via graphical elements, termed “devices”, that move and engage each other on top of existing windows, such as on a player's PC desktop or mobile device background. The devices may be tanks, spaceships, characters, or any other graphical element that can take part in a game or interaction. The system and method provides for short-term, casual, online games using light clients or instant messaging protocols. The games may be played quickly and easily, with minimal interruption of other endeavors. Players may conveniently choose opponents via a friends list, lobby system, or other such method, in an easy-to-use, e.g., drag-and-drop interface.

Abstract: An exercise bar, shaped like a motocross handlebar, that be attached to any multifunction gym. The user grips the bar as he/she would grip a regular motocross handlebar when working out, which works those muscles in the hands and arms that normally are used in motocross riding. A support bar is added to the top portion of the bar for added stiffness and to provide support for a retractable shaft for pulling exercises. A telescoping hook is also provided at the bottom to support a dumbbell that can be suspended at the bottom of the bar. The extended arm portions of the bar are fitted with locking hinges that allow the bar arms to fold for storage or for travel. A kit is also disclosed that allows the conversion of a standard handlebar into an exercise bar.

Abstract: A multiband antenna operates in at least a first frequency band and a second frequency band, a higher frequency band. A dipole has a first conductive leg and a second conductive leg and may be directly fed between the first and second legs. At least a portion of the first leg of the dipole has a meander configuration. The first leg has an electrical length of about one-quarter wavelength, or an odd multiple thereof, in the first frequency band and the second leg has an electrical length of about one-quarter wavelength, or an odd multiple thereof, or more in the first frequency band. A non-driven parasitically-excited conductive element is closely spaced to the first dipole leg and is electrically connected to the second dipole leg. The parasitic element has an electrical length of about one-quarter wavelength, or an odd multiple thereof, in the second frequency band.
