Abstract: A system and method are provided for capturing a flash image based on ambient and flash metering. In use, a first ambient condition is metered for a first ambient frame. Next, a first ambient capture time is determined based on the metering of the first ambient condition. Further, a first flash condition is metered for a first flash frame, and a first flash capture time is determined based on the metering of the first flash condition. Next, a first ambient frame is captured based on the first ambient capture time. After capturing the first ambient frame, a flash circuit is enabled during an active period and, a first flash frame is captured based on a combination of the first ambient capture time and the first flash capture time. Finally, a final image is generated based on the first ambient frame and the first flash frame.

Abstract: A light emitting diode (LED) flat panel lighting fixture is provided. The LED flat panel lighting fixture comprises an LED flat panel lighting device comprising (a) one or more LEDs and (b) one or more first mating mechanisms. The LED flat panel lighting fixture further comprises a mounting bracket comprising one or more second mating mechanisms configured to each mate with a corresponding one of the one or more first mating mechanisms when the LED flat panel lighting device is rotated within the mounting bracket and with respect to the mounting bracket. The rotation of the LED flat panel lighting device within a plane of the mounting bracket and with respect to the mounting bracket causes the mating of the one or more second mating mechanisms with the corresponding ones of the one or more first mating mechanisms.

Abstract: A method, apparatus, and article for solving the year 2000 problem involve processing a computer object program to identify object code instructions referencing date information for an operation which involves more than one century. The object code is altered by altering each identified instruction with an instruction to effect a transfer of control to a Year 2000 routine. The Year 2000 routine is a routine for altering the execution of an identified instruction in accordance with the Year 2000 routine and thereafter returning control to the object code.

Abstract: A Structured External Storage (SES) processor is linked by a communication means to one or more general purpose processors. Two or more applications executing on the one or more general purpose processors communicate function request messages to a message processor within the SES to effect serialized sharing of data within the SES. Within the message processor, a predicate function means executes unconditionally on receipt of one of the function request messages, and a data function means executes conditionally and atomically with respect to the predicate function means following a "successful" condition produced by the predicate function means.

Abstract: In order to combat flutter in rotor blades rotating within a duct bounded by a duct wall, the duct wall incorporates cavities tuned for resonance to a known flutter frequency. The cavities, which may comprise tubes immediately underlying a facing sheet of the duct wall, are arrayed around the circumference of the duct wall and communicate with the duct through openings in the duct wall near the tips of the blades. Flutter energy from the blades is transferred directly to the cavities by pressure waves and produces resonance in the cavities so that the flutter is damped aerodynamically. The invention is applicable to fans in turbofan engines.

Abstract: A gas turbine engine has a turbine which includes an annular array of rotary aerofoil blades surrounded by an annular shroud member. All or a major portion of the annular shroud member is constituted by a heat pipe. A distance measuring device is provided to measure the clearance between the tips of the rotary aerofoil blades and the shroud member and its output is monitored by a control unit. The control unit is adapted to control a valve which regulates the flow rate of cooling air directed onto the heat pipe. The arrangement is such that the temperature of the heat pipe is maintained at a level which is consistent with the clearance between the rotary aerofoil blade tips and the annular shroud member being within a predetermined range of values.

Abstract: Sparkplug means for an internal combustion engine are provided with conduits to introduce pre-combustion gases directly to a mixing area adjacent the sparking electrodes. This may be by connecting the conduits into the plug directly or by connecting them into an adapter to be interposed between the engine and the sparkplug, and providing a pre-combustion chamber therebetween. Preferably there is a mixing area upstream of the electrodes. An electrolyzer can be built into the arrangement to generate the pre-combustion gases immediately adjacent the sparkplug.

Abstract: An aerofoil blade for a gas turbine engine is in the form of a heat pipe. The aerofoil blade has an internal passageway adapted to contain a secondary structure and to thermally insulate that secondary structure from the remainder of the aerofoil blade by, for instance, the provision of a cooling air passage between the internal passageway and secondary structure.

Abstract: A stator aerofoil blade for a gas turbine engine is manufactured in the form of a heat pipe so that during engine operation, the blade remains substantially isothermal. Localized thermal gradients within the blade are minimized thereby reducing the possibility of blade distortion or cracking.A shroud ring for a gas turbine engine is manufactured in the form of a heat pipe so that during engine operation, the ring remains substantially isothermal. Localized thermal gradients within the ring are minimized, thereby reducing the possibility of ring distortion occurring.
