A combustor apparatus is provided, comprising a mixing arrangement for mixing a carbonaceous fuel with enriched oxygen and a working fluid to form a fuel mixture. A combustion chamber is at least partially defined by a porous perimetric transpiration member, at least partially surrounded by a pressure containment member. The combustion chamber has longitudinally spaced apart inlet and outlet portions. The fuel mixture is received by the inlet portion for combustion within the combustion chamber at a combustion temperature to form a combustion product. The combustion chamber further directs the combustion product longitudinally toward the outlet portion. The porous transpiration member is configured to substantially uniformly direct a transpiration substance laterally therethrough, about the perimeter thereof defining the combustion chamber and longitudinally between the inlet and outlet portions, toward the combustion chamber for buffering interaction between the combustion product and the porous transpiration member. Associated systems are also provided.

A System for providing communications over a communications network includes a communications interface and processor. The communications interface communicates over the communications network. The processor directs a communications scheduler to determine at least one metric for a path within the communications network. The processor also selects a data flow for the path and determines whether to transmit a packet in the selected data flow based on the at least one metric. The processor then directs a communications protocol handler to generate the packet for the selected data flow.

A homogeneous ceria-based mixed-metal oxide, useful as a catalyst support, a co-catalyst and / or a getter has a relatively large surface area per weight, typically exceeding 150 m<2> / g, a structure of nanocrystallites having diameters of less than 4 nm, and including pores larger than the nanocrystallites and having diameters in the range of 4 to about 9 nm. The ratio of pore volumes, VP, to skeletal structure volumes, VS, is typically less than about 2.5, and the surface area per unit volume of the oxide material is greater than 320 m<2> / cm<3>, for low internal mass transfer resistance and large effective surface area for reaction activity. The mixed metal oxide is ceria-based, includes Zr and or Hf, and is made by a novel co-precipitation process. A highly dispersed catalyst metal, typically a noble metal such as Pt, may be loaded on to the mixed metal oxide support from a catalyst metal-containing solution following a selected acid surface treatment of the oxide support. Appropriate ratioing of the Ce and other metal constituents of the oxide support contribute to it retaining in a cubic phase and enhancing catalytic performance. Rhenium is preferably further loaded on to the mixed-metal oxide support and passivated, to increase the activity of the catalyst. The metal-loaded mixed-metal oxide catalyst is applied particularly in water gas shift reactions as associated with fuel processing systems, as for fuel cells.

Systems and methods for applying guided active compression decompression cardiopulmonary resuscitation are provided. Exemplary systems include a load cell, a handle, an adhesive pad. The handle and the adhesive pad are configured for magnetic coupling.

An insulation product, and method of making the same, is provided comprising a mat containing randomly oriented fibers bonded by a binder, the mat having first and second major surfaces and a pair of side portions, and at least one flexible reinforcing layer bonded to the mat between the first and second major surfaces and extending along a length of said mat.

A method for distributing voice-recognition grammars includes receiving match data from a first remote element. The match data includes information associated with an attempt by the remote element to match received audio information to first stored audio data. The method also includes generating a grammar entry based on the match data. The grammar entry includes second stored audio data and a word identifier associated with the second stored audio data. Additionally, the method includes transmitting the grammar entry to a second remote element.

A radio frequency amplifier system is disclosed in which the amplifier bias supply and power supply voltages are instantaneously modulated with signals derived from the envelope voltage of the input signal. Separate non-linear mapping functions are used to derive the supply and bias voltages. The two mapping functions are optimised jointly to achieve particular system performance goals, such as optimum efficiency, constant gain, constant phase, or minimum spectral spreading. An optimisation of particular interest is that which achieves best RF amplifier power added efficiency subject to achieving constant amplifier gain. In this way the need for pre-distortion linearization may be reduced or eliminated.
