Abstract: A system and method for remotely monitoring and/or controlling an apparatus and specifically for remotely monitoring and/or controlling street lamps. The lamp monitoring and control system comprises lamp monitoring and control units, each coupled to a respective lamp to monitor and control, and each transmitting monitoring data having at least an ID field and a status field; and at least one base station, coupled to a group of the lamp monitoring and control units, for receiving the monitoring data, wherein each of the base stations includes an ID and status processing unit for processing the ID field of the monitoring data.
Abstract: A friction damped turbine blade is disclosed. The turbine blade is formed of segments configured so as to form an assemblage corresponding to the airfoil shaped body. Each of the segments is in slidable contact with an adjacent segment. During turbine operation, the segments rub against one another due to the stresses placed on the blade, imparting frictional damping to the turbine blade.

Abstract: Methods and apparatus for combusting a fuel with an oxidant are described, the apparatus comprising a ceramic burner block, the burner block having a back face and a front face. The burner block has at least one oxidant cavity in an upper portion of the burner block, and at least one fuel cavity in a lower portion of the burner block, each cavity extending from the back face to the front face. The at least one oxidant cavity has positioned therein a fuel supply conduit, the fuel supply conduit having a fuel supply conduit exit positioned a sufficient distance from the front face to allow combustion of at least a portion of fuel exiting the fuel supply conduit exit with at least some of the oxidant traversing the oxidant cavity, and the least one fuel cavity having connected thereto, near the back face, an oxidant conduit, thereby allowing mixing of a minor portion of the oxidant with the fuel.

Abstract: A process additive for polyolefin films and foams produces products having reduced aging time and reduced greasiness and reduced grease-like transfer as compared to glycerol monostearate (GMS). Carbon dioxide based blowing agents are suitable. The process additive comprises a fatty acid N-aliphatic alcohol amide of the general formula R—CON(R′)R″. R is a fatty hydrocarbon radical having from about 8 to 30 carbons. R′ typically is hydrogen. R′ can also be an alkyl radical of from about 1 to 6 carbons or an alkyl alcohol radical of from about 1 to 6 carbons. R″ is an alkyl alcohol fragment of from about 1 to 6 carbons. The alkyl alcohol fragments can be monohydric or polyhydric. Secondary fatty monoalkanolamides in which R′ is hydrogen are particularly useful, especially stearamide monoethanolamine (MEA).
Abstract: A twin spool counter-rotating turbofan gas turbine engine having a counter-rotating fan module integrated with the high pressure compressor and driven by a counter-rotating turbine utilizing only two drive shafts. The two drive shafts are aerodynamically coupled and rotate in opposite directions relative to each other with or without the use of a gearbox. The integration between the fan module and high pressure compressor allows the fan blade rows to operate at the same mechanical speed of the high pressure compressor blade rows. An afterburner module may be added to the present invention to provide thrust augmentation.

Abstract: In a microwave communications link, an antijamming antenna system with enhanced main beam nulling is realized by providing gain in the difference port output of a monopulse antenna compared to the sum port. As a consequence interference signals are nulled out at much closer angles to the desired signal than is the case when the gain is the same in both channels. The gain is introduced when a dominant jammer is detected. Detection of a dominant jammer is identified for the conditions in which the monopulse sum channel power level exceeds the sum of the difference channel power levels and the system processor output signal/noise ratio is unsatisfactory.
