Improved integrity test, priming sequence and bag height detection tests, apparatuses and methods for a medical fluid delivery system are provided. The integrity test includes a plurality of air pressure decay tests, using positive and negative pressure. The priming sequence includes pumping fluid through a portion of a patient line to be primed to overcome air in the line and other potential obstacles. The head height test measures a pressure build-up or drop-off within a pump chamber of a membrane pump. The measured pressure corresponds to a head height between a fluid supply and the pump or between the pump and a fluid drain. A determination is made whether the corresponding head height is acceptable.

A method of digital image enhancement and sharpening (11, 12) which may be applied to restoration of blurred digital images of arbitrary origin. The method uses a specially formulated constraint (15) to reconstruct the original images. In particular, the constraint of the present method minimizes the area where strong image parameter variations and discontinuities occur. This new constraint is called a minimum gradient support (MGS) constraint. The MGS constraint generates a stable sharp solution of the linear ill-posed image restoration equation with an arbitrary blurring operator.

A fuel cell system with fuel processor for integration with a marine vessel propulsion system. The system includes an auto thermal reactor that is the fuel processor for producing hydrogen from a fuel source. The fuel source is preferably ethanol or biodiesel or a mixture thereof, but can also be a sulfur containing fuel like petrodiesel of JP-8. The system further includes a gas-water shift reactor for further production and concentration of the hydrogen from the auto thermal reactor output. The system also includes a hydrogen permeable membrane separator for generating suitable quantities of essentially pure hydrogen to the fuel cell. The system also includes an oxygen permeable membrane separator for concentrating oxygen and reducing nitrogen to improve the partial pressure of hydrogen in subsequent fuel processing steps. The system contemplates the use of a Polymer Electrolyte Membrane (PEM) fuel cell. The system minimizes preheating of catalysts or other components to the extent just needed to initiate the fuel processor. To that end, heat sources and sinks of the system and associated usage systems are matched so as to minimize heat collection, storage and distribution systems. Water is recycled within the system to the extent necessary to maintain a water balance in the fuel processor and the fuel cell stack(s). The system includes cooling of the fuel cell stack(s) and integrated heat recovery with exothermic and endothermic catalysts. The fuel processor / fuel cell system components are configured to conform to and take advantage of the available space and limitations, such as the space constraints and opportunities associated with a marine vessel.

If the client has not exceeded the threshold number of allowable connections preset, allowing the one or more connections up to the threshold number of allowable connections preset for the client to download the file from the server and if the client has exceeded the threshold number of allowable connections preset, preventing the client from connecting to the server, such that overloading of the server with too many simultaneous active connections is minimized.

Embodiments consistent with the present invention provide a credit enhancement structure for risk allocation between parties that minimizes the regulatory capital reserve requirement impact to an institution subject to capital reserve requirement. A subject pool of assets held by the institution, such as a pool of loans, is rated to determine its risk levels. Based on the rated risk levels, a guarantor party agrees to be responsible for a portion of the risk associated with the pool of assets, which may define the maximum risk exposure of the institution holding the asset pool. The risk-rated capital reserve requirements are applied to the asset pool based on the risk level rating and the guarantor's agreed upon risk responsibility such that the institution holds a reduced amount of reserve capital compared to what it would otherwise be required to hold.

A “Wi-Fi Multicaster” provides a practical and efficient Wi-Fi multicast system for environments having potentially large numbers of Wi-Fi clients. Significantly, the Wi-Fi Multicaster does not require any changes to the 802.11 protocol, or to the underlying Wi-Fi infrastructure. In various embodiments, the Wi-Fi Multicaster uses pseudo-broadcast, and augments it with destination control, association control and optional proactive FEC (forward error correction) to improve multicast performance. More specifically, the Wi-Fi Multicaster system converts multicast packets to targeted unicast transmissions. To minimize the amount of airtime consumed, the Wi-Fi Multicaster uses destination control in combination with various algorithms for association control. Further, in various embodiments, the Wi-Fi Multicaster includes an adaptive, proactive FEC scheme to reduce overall packet losses. Finally, to overcome the challenges posed by encryption protocols such as 802.1x, the Wi-Fi Multicaster uses a “virtual multicast interface” that allows clients to “share” a common key for each multicast.

Methods and apparatus, including computer systems and program products, for sharing data objects in runtime systems. An identification of a first data object in a first runtime system is received. The first data object references zero or more referenced data objects. A shared closure of data objects, which consists of the first data object and a transitive closure of the referenced data objects, is identified, and a determination is made as to whether the shared closure of data objects is usable in a second runtime system. In some implementations, determining whether a shared closure is usable in a second runtime system includes determining whether each data object in the shared closure is serializable without execution of custom code, or determining whether the runtime class of each object instance in the shared closure is shareable. Using shared closures to share objects between runtime systems can provide isolation between user sessions.

Hydrofluoric acid (HF) mixed with water and often buffered with ammonium fluoride is a standard silicon dioxide wet etchant which is followed by a rinse. An improved silicon dioxide etch is vapor HF which may be followed by a water vapor rinse. The invention discloses a further improved silicon dioxide etch. Following an initial exposure to vapor HF for oxide removal, a first insitu water rinse occurs. A second exposure to vapor HF then occurs and is followed by a second insitu water rinse. Water, rather than water vapor, aids in freeing particles from the wafer surface. During both the water rinses, the wafer may be rotated at increasing speeds to aid in sweeping particles from wafer surface. The process may be practiced in a commercially available reactor and is suitable for ULSI devices having complex topographies, such as, for example, 64 megabit DRAMs employing crown type memory cells.
