Abstract: A data processing system includes a vector data processing unit that includes a shared scheduler queue configured to store in a same queue, at least one entry that includes at least a mask type instruction and another entry that includes at least a vector type instruction. Shared pipeline control logic controls a vector data path or a mask data path, based a type of instruction picked from the same queue. In some examples, at least one mask type instruction and the at least one vector type instruction each include a source operand having a corresponding shared source register bit field that indexes into both a mask register file and a vector register file. The shared pipeline control logic uses a mask register file or a vector register file depending on whether bits of the shared source register bit field identify a mask source register or a vector source register.

Abstract: A capillary pumped loop for transferring heat from one body part to another body part, the capillary pumped loop comprising a capillary evaporator for vaporizing a liquid refrigerant by absorbing heat from a warm body part, a condenser for turning a vaporized refrigerant into a liquid by transferring heat from the vaporized liquid to a cool body part, a first tube section connecting an output port of the capillary evaporator to an input of the condenser, and a second tube section connecting an output of the condenser to an input port of the capillary evaporator. A wick may be provided within the condenser. A pump may be provided between the second tube section and the input port of the capillary evaporator. Additionally, an esternal heat source or heat sink may be utilized.

Abstract: A wick for use in a capillary loop pump heat pipe. The wick material is an essentially uniformly porous, permeable, open-cell, silicon dioxide/aluminum oxide inorganic ceramic foam having a silica fiber to alumina fiber ratio, by weight, of about 78 to 22, respectively, a density of 6 lbs/ft.sup.3, and an average pore size of less than 5 microns. A representative material having these characteristics is Lockheed Missiles and Space Company, Inc. HTP 6-22. This material is fully compatible with the FREONs and anhydrous ammonia and allows for the use of these very efficient working fluids, and others, in capillary loops.
