Abstract: An annular exhaust duct of a gas turbine engine includes inner and outer cases co-axially disposed, and radially spaced apart by a plurality of airfoils radially extending therebetween. The outer case includes a connection apparatus for supportably connecting the exhaust duct to the gas turbine engine and the inner case includes an axial end portion at a rear end thereof for connection with a tail cone. The axial end portion bends radially and inwardly at a rear extremity thereof to stiffen the rear end of the inner ease.

Abstract: The present invention provides for a method that could be advantageously implemented in a satellite local area network (LAN) in which an average number of sites share a TDMA link. The invention provides for both a dedicated bandwidth to all the sites and a shared bandwidth that is dynamically assigned to the sites, therefore allowing for both synchronous traffic and for on request burst mode traffic. The method includes a reservation method of this shared bandwidth which is specially optimized for a satellite link. The method provides also for a network that automatically managed its communication bandwidth resources and the synchronization of the sites, without the need of an external controller. The present invention also provides for a satellite modem to transmit data from a site, to receive data from the sites and to manage the bandwidth resources of the TDMA satellite in accordance with the above method.

Abstract: An electric alternator/motor having a stator with at least two non-overlapping sectors is provided. Each sector includes a first winding, first and second magnetic circuits and a saturation control assembly. A cross-talk reduction feature, such as a peripheral slit is provided between each sector of the stator for impeding magnetic flux crossing between the sectors.

Abstract: The present invention provides an alternative to the auto-throttle integrated in an aircraft autopilot by restricting the conditions in which the system operates. The proposed system removes the auto-throttle function from the autopilot system and gives it directly to the Full Authority Digital Engine Control (FADEC). A cruise control mode is available to the pilot only under stable flight conditions.

Abstract: A data processing system containing a monolithic network of cells with sufficient redundancy provided through direct logical replacement of defective cells by spare cells to allow a large monolithic array of cells without uncorrectable defects to be organized, where the cells have a variety of useful properties. The data processing system according to the present invention overcomes the chip-size limit and off-chip connection bottlenecks of chip-based architectures, the von Neumann bottleneck of uniprocessor architectures, the memory and I/O bottlenecks of parallel processing architectures, and the input bandwidth bottleneck of high-resolution displays, and supports integration of up to an entire massively parallel data processing system into a single monolithic entity.

Abstract: There is described a device for use with a position sensing system for tracking a bone in a reference coordinate system, the device comprising a fabric removably and non-invasively attachable to a bone and having a plurality of reference markers distributed thereon, the reference markers being one of passive and active devices recognized by the position sensing system and positioned and oriented in the reference coordinate system with respect to a fixed reference.

Abstract: An exhaust duct for directing a stream of exhaust gases in a gas turbine engine is provided. The exhaust duct comprises an inlet for receiving the stream of exhaust gases from a turbine section of the gas turbine engine; an outlet in fluid communication with the inlet; and a transition portion defining a passage between the inlet and the outlet. The passage comprises an annular region having a first side portion and a second side portion that are separated by a flow splitter. At least one bypass channel interconnects the first side portion and the second side portion of the annular region.

Abstract: The present invention relates to the identification of the cytosolic phosphoprotein CRMP4b as a protein that physically and functionally interacts with RhoA to mediate neurite outgrowth inhibition. siRNA-mediated knockdown of CRMP4 promotes neurite outgrowth on myelin substrates indicating a critical role for CRMP4 in neurite outgrowth inhibition. Disruption of CRMP4b-RhoA binding with a competitive inhibitor attenuates neurite outgrowth inhibition on myelin and aggrecan substrates. Stimulation of neuronal growth cones with Nogo leads to co-localization of CRMP4b and RhoA at discrete regions within the actin-rich central and peripheral domains of the growth cone indicative of a potential function in cytoskeletal rearrangements during neurite outgrowth inhibition. Together these data indicate that a RhoA-CRMP4b complex forms in response to inhibitory challenges in the growth cone environment and regulate cytoskeletal dynamics at distinct sites necessary for axon outgrowth inhibition.

Abstract: A personal watercraft (10) comprises a floatation platform (12) and a separate module (14) including a water propulsor driving crank mechanism (22) and a keel (38) mounting the water propulsor. The separate module (14), when mounted to the platform (12), extends at right angles to the platform with the keel (38) and propeller (40) extending below the platform (12) and the propulsor driving crank mechanism (22) extending above the platform. The separate module (14) is readily separable from the platform (12) for ease of storage and transport.
