摘要： A method of providing electrical power using a split bus configuration includes receiving a first direct current at a positive bus of a split bus, where the first direct current originates from a first fuel cell segment. A second direct current is received at a negative bus of the split bus, where the second direct current originates from a second fuel cell segment. A third direct current is also received at the split bus such that a combined direct current is formed including the first direct current, the second direct current, and the third direct current. The third direct current originates from an alternative direct current (DC) source. The combined direct current is provided to an inverter such that an alternating current is generated for a load.

摘要： In one example embodiment, the method includes receiving an X.25 packet at a LAN interface of a network device. Further, the method includes determining whether a local CUG value is associated with the X.25 packet. The local CUG value may be replaced with a network CUG value associated with the X.25 packet. Thereafter, the X.25 packet, and the associated network CUG value, may be formatted to generate an IP packet. The formatting may include the use of at least one formatting regime including encapsulating the X.25 packet, that includes the associated network CUG value, in an XOT, or using protocol translation to translate the X.25 packet that includes the network CUG value into an equivalent IP packet. The method includes transmitting the IP packet using a WAN interface card, the WAN interface card including a primary interface, and at least one backup interface.

摘要： An absorbent, flushable, bio-degradable, and medically-safe nonwoven fabric suitable for use as wraps, wipes, absorbent pads, etc., is composed of from 2% to 10% by weight of untreated, water-soluble polyvinyl alcohol (PVA) fibers that are heat-bonded to a matrix of absorbent fibers. The use of PVA fibers in low amounts provides softness, while sufficient wet strength is provided by heat bonding the PVA fibers completely to the other fibers in a two-stage heating process. The resulting nonwoven fabric has a high wet-to-dry tensile strength ratio, good drape softness, and high fluid absorptive capacity. In a method for producing the nonwoven fabric, the PVA fibers are blended with the absorbent fibers, the blended fibers are carded onto a moving web, sufficient water is added to wet the PVA fibers while maintaining web integrity, then the web is heated in two stages, the first with heating cylinders at 40.degree. C. to 80.degree. C., then the second with heating cylinders of 60.degree. C. to 100.degree. C. The fiber web may also be hydroentangled and patterned for enhanced strength and textural properties.

摘要： A tobacco smoking device comprises a porous mass of active particles adapted to enhance a tobacco smoke flowing over said active particles and binder particles. The active particles comprises about 1-99% weight of the porous mass, and the binder particles comprises about 1-99% weight of said porous mass. The active particles and said binder particles are bound together at randomly distributed points throughout the porous mass. The active particles have a greater particle size than the binder particles.
