Abstract: A circuit performs a method of arbitrating requests between multiple requestors. The method includes accessing, via an arbitration processor, a requestor random access memory (RRAM) having multiple entries. Each entry corresponds to a requestor and includes a valid field indicating whether or not the requestor is requesting. One of the multiple entries is selected in a round robin manner as a function of a value in the valid field indicative of the corresponding requestor requesting. The corresponding requestor requesting arbitration is notified.

Abstract: Described is a technology by which a virtual machine may be safely migrated to a computer system with a different platform. Compatibility of the virtual machine may be checked by comparing the virtual machine's capabilities against those of the new platform. To ensure compatibility, when created the virtual machine may have its capabilities limited by the lowest common capabilities of the different platforms available for migration. Computer systems may be grouped into migration pools based upon similar capabilities, and/or a virtual machine may be mapped to certain computer systems based upon capabilities needed by that virtual machine, such as corresponding to needed performance, fault tolerance and/or flexibility.

Abstract: A method for manufacturing a high ductility and high hot tensile strength tungsten wire for incandescent lamp filaments is disclosed. The method comprises the steps of preparing a tungsten alloy, swaging a tungsten rod from the alloy, and drawing the swaged rod to wire size in multiple drawing passes. In the method, the wire is annealed between predetermined draws. It is proposed that an annealing is performed before the final drawing pass, by annealing the wire at a temperature between 1100-1300° C. There is also provided a tungsten wire for incandescent lamp filament, which has high ductility and high hot tensile strength. The tungsten wire of the invention has a cold tensile strength-hot tensile strength ratio not exceeding 3.5.

Abstract: A tungsten-rhenium filament for an operation temperature between 2900 and 3200° K is disclosed. The filament comprises an aluminum-potassium-silicon (AKS) additive. The filament has a grain microstructure comprising substantially exclusively elongated interlocking grains with a Grain Aspect Ratio (GAR) not less than 12. The rhenium content of the filament is between 0.2-0.4% by weight. A method for manufacturing a rhenium-tungsten filament is also disclosed. The method comprises the following steps. An AKS doped tungsten-rhenium alloy powder is prepared with a rhenium content of 0.2-0.4% by weight. The alloy powder is pressed and presintered, and thereafter sintered with direct current. A rhenium-tungsten filament is formed, which has a metastable crystal structure. The filament is annealed below the recrystallisation temperature, and recrystallised above the crystallization temperature. There is also provided a halogen incandescent lamp with a glass envelope enclosing a tungsten-rhenium filament.

Abstract: An inlead for an electric lamp formed of an alloy of tungsten and molybdenum. The inlead has a rate of thermal expansion or contraction approximating that of the glass forming the bulb. This minimizes the expansion/contraction mis-match stress between the two materials. In addition, the alloy composition functions to reduce oxidation and degradation of the lead.
