Abstract:
An apparatus for communicating packets in a network environment is provided that includes a first network element that includes a first neighbor list, the first network element being coupled to a second network element and a third network element. The first network element is operable to receive a second neighbor list from the second network element and a third neighbor list from the third network element. The first network element is further operable to determine one or more overlaps provided by the second and third neighbor lists when compared to the first neighbor list, the first network element relaying an update that it receives based on the one or more overlaps.
Abstract:
A method for communicating packets in a network environment is provided that includes receiving a packet at a network element and identifying a sequence number included in the packet that correlates to awareness information associated with one or more adjacent network elements. A table included in the network element may be updated in order to account for the awareness information included within the packet that has not been accounted for by the network element. In cases where the awareness information included in the packet has already been accounted for, the packet may be ignored.
Abstract:
The present invention relates to a fan-forced positive pressure breathing apparatus commonly known as a Powered Air Purifying Respirators (PAPR) system, and specifically concerns the connecting of the breathing components of such equipment. The invention is a method and apparatus for rapid engagement of PAPR breathing components (such as air supply lines and filter elements to a blower housing). The invention also provides for indicating and/or monitoring whether the relative components have been aligned and coupled in sealed engagement.
Abstract:
A system 11 for controlling an arc welding system 10 operating in a dip transfer mode is disclosed. The control system is operative to control the current output from a power source so as to apply a current pulse during the arcing phase of the welding system which is operative to form a molten droplet on the electrode of the welding torch 13 which is within a predetermined threshold size range, The control system 11 is then operative to clamp the current output from the power source 12 so that bridge rupturing occurs at relatively low current levels to thereby significantly reduce spatter during bridge rupturing.
Abstract:
Methods are provided for quenching undesired side reactions of pathogen inactivating compounds in biological materials. In a particular embodiment, methods are provided for quenching undesired side reactions of a pathogen inactivating compound that includes a functional group which is, or which is capable of forming, an electrophilic group. In this embodiment, the material is treated with the pathogen inactivating compound and a quencher, wherein the quencher comprises a nucleophilic functional group that is capable of covalently reacting with the electrophilic group. The electrophilic group on the pathogen inactivating compound is preferably a non-radical cationic group. In one embodiment, the pathogen inactivating compound includes a nucleic acid binding ligand and a mustard group, wherein the mustard group is capable of reacting in situ to form the electrophilic group. Preferred quenchers are thiols, such as glutathione. Biological materials which may be treated include whole blood, red blood cells, blood plasma, and platelets. The methods permit inhibition of the modification of red blood cells in red blood cell containing materials during pathogen inactivation.
Abstract:
Methods and compositions for treating pathogens in material are described, including methods of decontaminating human fluids prior to processing in the clinical laboratory and methods for decontaminating blood products prior to in vivo use. The techniques handle large volumes of human serum without impairing the testing results. Novel compounds for photodecontaminating biological material are also contemplated which are compatible with clinical testing, in that they do not interfere with serum analytes.
Abstract:
Compounds and methods for inactivating pathogens in materials are described, including compositions and methods for inactivating pathogens in biological materials such as red blood cell preparations and plasma. The compounds and methods may be used to treat materials intended for in vitro or in vivo use, such as clinical testing or transfusion. The compounds are designed to specifically bind to and react with nucleic acid, and then to degrade to form breakdown products. The degradation reaction is preferably slower than the reaction with nucleic acid.
