Abstract: A non-aircraft-propelling auxiliary gas turbine engine assembly includes an auxiliary gas turbine engine and a mixing damper. The auxiliary engine and the mixing damper are installable in an aircraft having at least one aircraft-propelling main gas turbine engine. The auxiliary engine includes a compressor having a compressor inlet. The mixing damper has first and second inlets and has an outlet. The outlet is fluidly connectable to the compressor inlet. The first and second inlets are adapted to receive first and second gas streams which have been compressed by at least one main engine. An aircraft component includes a mixing damper. A controller includes a program which instructs the controller to increase/decrease a first gas stream in response to increasing/decreasing electrical demands on an electric generator operatively connected to an auxiliary gas turbine engine of an aircraft.

Abstract: An apparatus and method for controlling rotating bladed machinery by using a source of pressurized gas is disclosed. The source of pressurized gas, such as air, imparts braking torque on a turbomachinery component through the use of one or more impinging orifices or jets. The orientation of the jets is such that the transfer of momentum from the pressurized gas results in a force substantially opposite the direction of rotation of the turbomachinery component. This transfer of momentum from the pressurized gas allows for a controlling torque to be applied to the turbomachinery component without the need of mechanical and/or electrical devices applying torque to the rotating shaft.

Abstract: We have performed separation of bacterial and cancer cells from peripheral human blood in microfabricated electronic chips by dielectrophoresis. The isolated cells were examined by staining the nuclei with fluorescent dye followed by laser induced fluorescence imaging. We have also released DNA and RNA from the isolated cells electronically and detected specific marker sequences by DNA amplification followed by electronic hybridization to immobilized capture probes. Efforts towards the construction of a “laboratory-on-a-chip” system are presented which involves the selection of DNA probes, dyes, reagents and prototyping of the fully integrated portable instrument.

Abstract: The invention provides arrays of immobilized probes, and methods employing the arrays, for detecting mutations in the biotransformation genes, such as cytochromes P450. For example, one such array comprises four probe sets. A first probe set comprises a plurality of probes, each probe comprising a segment of at least three nucleotides exactly complementary to a subsequence of a reference sequence from a biotransformation gene, the segment including at least one interrogation position complementary to a corresponding nucleotide in the reference sequence. Second, third and fourth probe sets each comprise a corresponding probe for each probe in the first probe set.

Abstract: The invention relates to compositions and methods useful in the detection of nucleic acids using a variety of amplification techniques, including both signal amplification and target amplification. Detection proceeds through the use of an electron transfer moiety (ETM) that is associated with the nucleic acid, either directly or indirectly, to allow electronic detection of the ETM using an electrode.

Abstract: A high density optical connecting block 100 is mounted in a relatively thin, flat panel 10, and is constructed as an array of identical cells 110 that are linked together as a one-piece unit. The connecting block has a front-to-back depth that is greater than ten millimeters for imparting flexural rigidity to the panel. The array includes at least twelve cells that are arranged in two or more rows and two or more columns. Each cell has a front side that is shaped to receive and interlock with a duplex optical connector 50, and a back side that is shaped to receive and interlock with two simplex optical plugs 20. The duplex connector is a unifying structure that yokes a pair of simplex optical plugs 20-1, 20-2 into a duplex configuration.

Abstract: The present invention is directed to an improved logging apparatus. The logging apparatus includes transmitters, receivers, and a controller member. The controller member is utilized to selectively energize the transmitters to generate an interrogation signal. The receivers are utilized to obtain measurements of the interrogation signal. The controller member can be utilized to substantially simultaneously process the recorded samples--such as by mathematically combining a plurality of measurements in order to obtain a measure of an attribute value which relates to at least one of the wellbore and surrounding formation.
