  • Patent number: 7949440
    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.

  • Patent number: 7948963
    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.

  • Patent number: 7944187
    Abstract: Methods and apparatuses are disclosed for producing current with a desired output frequency from one or more fixed or variable speed alternators by varying a saturation level of a portion of the alternator(s) based on a output frequency desired, and preferably then rectifying the output to produce a desired electrical output which may be provided as direct current or alternating current to a suitable load.

  • Patent number: 7941572
    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.

  • Patent number: 7935349
    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.
