Abstract: A device, a system, and methods for tracking conductive composite pressurized gaseous storage tanks. The system including anchoring an RFID device in a non-conductive blind boss, wherein the anchor material has a low dielectric and has minimal reflection of RF energy.

Abstract: Disclosed is a device and method of a system and an improved boss, the boss having a longitudinally extending body with a top surface having flange forming a planar bottom surface with a fluid connection through the boss further including a liner mounting connection (LMC) on the flange bottom surface; the LMC having a groove adapted to be threadably engaged with a liner neck; and, a migration passage fluidly connecting LMC to the fluid connection of the boss.

Abstract: A composite fuel tank, formed by winding filaments or strips around a plastic liner and binding the material with a curable binder. Embedded within the wrapped material at predetermined depths from the surface which provides a color indication of the level of damage due to tears, gashes, cuts and the like. The color indicator is part of a visual inspection method to determine tank damage and the extent of repair necessary.

Abstract: The present invention is directed to a continuous process for pretreating a lignocellulosic feedstock. A feedstock slurry is provided, which has a solids concentration of 10% to 33% by weight. The feedstock slurry is pumped through a heating train of at least two stages, each stage including a pump to increase stage pressure and a direct steam injection to heat the feedstock slurry. Acid is also added to the feedstock slurry prior to the heating train, during a heating stage, or after leaving the heating train; the acid is added at a concentration of 0% to 12% weight of acid on weight of initial feedstock. A heated, acidified feedstock slurry is thus produced. The heated, acidified feedstock slurry is flowed through a pre-treatment reactor at a temperature of 160° C. to 280° C. for a time sufficient to increase efficiency of conversion of cellulose in the feedstock to glucose using cellulase enzymes.

Abstract: A current mode logic voter circuit includes three two-input split NOR gates. Each two-input split NOR gate receives a corresponding pair of input signals and generates a pair of first output signals responsive to the input signals. A three input split NOR gate is coupled to the two-input split NOR gates to receive the first output signals and generates a second pair of output signals responsive to the first output signals from the two-input split NOR gates. The two and three-input split NOR gates can be formed from current mode logic buffer circuits, and in one embodiment in the three-input split NOR gate the buffer circuits are hardened.

Abstract: An apparatus is provided for communicating over a network images captured by a digital camera, such as a digital camera without an on-board network interface. The apparatus includes a housing separate from the digital camera having a processing unit with memory for storage of images, a camera interface card received in a memory card slot of the digital camera, and a cable or wireless connection coupling the camera interface card to the processing unit for data communication. The apparatus emulates a memory card to the digital camera, such that the digital camera's electronics operate with the memory of the processing unit through the camera interface card, as if such memory was on a memory card located in slot of the digital camera. Images captured by the digital camera are transferred, via the camera interface card and cable, to memory of the processing unit, and the digital camera can access images stored in memory of the processing unit.
