Abstract: The present disclosure provides an alternative, cost-effective safety feature for on-board hydrogen storage containers incorporating a fill cycle sensor with a driver warning and shutdown system. The system monitors the number of times a hydrogen container is filled, and then takes action at a predetermined termination point. A controller monitors each time the hydrogen container is filled above 90% of the rated pressure or mass. Once the predetermined termination point of fill cycles is reached, the disclosed device/method will either disable the valve or refueling mechanism such that fuel supply to the vehicle is shutoff and the container cannot be filled again, essentially assuring the end of the life of the container.

Abstract: A filling system includes a pressurized source of fill material and a pressure fill head wherein the fill head also includes a beating element positioned so as to transfer heat to fill material passing through the fill head. A method of filling holes using a fill material passing through a pressure fill head includes the steps of causing fill material to enter the fill head\, modifying the viscosity of the fill material while it is within the fill head, and causing the modified viscosity fill material to exit the fill head and enter at least one hole.

Abstract: A method for filling vias in an electronic substrate which includes providing a source of fill material; providing a pressure head coupled to the source of fill material via a fill material inlet, the pressure head further comprising an elongated fill material outlet which is substantially larger than the fill material inlet; placing the pressure head in contact with the electronic substrate; and pressurizing the fill material to inject fill material into the vias of the electronic substrate.

Abstract: A system comprising a scavenging blade, a printed wiring board receiving portion, and a movement mechanism adapted to move the scavenging blade and printed wiring board receiving portion relative to each other, and to a method of removing excess fill material comprising providing a printed wiring board having filled holes and at least some excess fill material on a surface of the printed wiring board, providing a system comprising a scavenging blade, positioning the printed wiring board in the system, and causing the scavenging blade to traverse at least a portion of the printed wiring board in a manner that causes the scavenging blade to remove at least a portion of the excess fill material from the printed wiring board.

Abstract: A portable hydrogen refueling stations which can dispense gaseous hydrogen from one or more internal high pressure tanks. The refueling station can be refilled with a lower pressure hydrogen gas feed and then compressed for storage within the refueling station.
