Abstract: A microprocessor-PLD hybrid architecture includes an IPC microprocessor and a PLD in signal communication with the IPC microprocessor via an IPC interface. The IPC microprocessor outputs a data read command to initiate a data read operation or a data write command. The PLD includes a plurality of PLD modules that store data and a bus controller. The bus controller communicates with the plurality of PLD modules via a plurality of PLD interfaces and is configured to sequentially execute a set of bus controller instructions. The bus controller reads data from a target PLD module from among the plurality of PLD modules in response to receiving the data read command, and transfers the data to the IPC microprocessor. The bus controller receives data from the IPC microprocessor and stores the data in a target PLD module from among the plurality of PLD modules in response to receiving the data write command.

Abstract: A bus controller-based page memory programmable logic device (PLD) architecture includes a plurality of PLD modules and a bus controller in signal communication with the plurality of PLD modules via a universal bus interface.

The bus controller includes bus memory unit configured to store second data and includes a bus controller engine configured to sequentially execute a set of bus controller instructions. One or both of the first data and the second data is transferred between the bus controller and a target PLD module among the plurality of PLD modules in response to sequentially executing the set of bus controller instructions.

Abstract: A bus controller-based programmable logic device (PLD) architecture is provided and includes a dual-port unit interposed between bus controllers. The dual port unit includes first and second data transfer layers. The first data transfer layer includes write and read areas for data transfer between the first and second bus controllers, respectively. A write to the read area is prevented during a read by the second bus controller. The second data transfer layer includes read and write areas for data transfer between the first and second bus controllers, respectively. A write to the read area is prevented during a read by the first bus controller.

Abstract: A closures mechanism for a door actuated during a fire, which causes the door to automatically close. The present invention provides a hinge with opposing hinge plates comprising a door leaf and a frame leaf each pivotal around a hinge pin and spring. A hinge spring nub is anchored within a channel having a fusible block that prevents the spring nub and tension from traveling the channel. At a predetermined temperature the fusible block ruptures causing the spring nub and spring tension to move into engagement with the door attached to the hinge door leaf thereby causing the door to close by means of the tensioned spring's kinetic energy.

Abstract: A system for performing a multiphysics simulation. The system includes a computing device, a database and a plurality of service proxy modules. The computing device includes a processor. The database is communicably connected to the processor and is associated with a plurality of data models. The plurality of service proxy modules are communicably connected to the processor. Each service proxy module is configured to extract at least a portion of the database for use by a service communicably connected thereto.

Abstract: The present invention relates to a novel class of sulfonamides which are aspartyl protease inhibitors. In one embodiment, this invention relates to a novel class of HIV aspartyl protease inhibitors characterized by specific structural and physicochemical features. This invention also relates to pharmaceutical compositions comprising these compounds. The compounds and pharmaceutical compositions of this invention are particularly well suited for inhibiting HIV-1 and HIV-2 protease activity and consequently, may be advantageously used as anti-viral agents against the HIV-1 and HIV-2 viruses. This invention also relates to methods for inhibiting the activity of HIV aspartyl protease using the compounds of this invention and methods for screening compounds for anti-HIV activity.

Abstract: A line cutter 1 is fitted at a propeller 2 on a shaft 3 carried in a stern tube 4. Clamped to the shaft immediately in front of the propeller is a rotatable cutting blade unit 11 comprising a split hub 12, having two halves 121, 122, one of which carries one rotating blade 14 and the other of which carries two further blades 15. Bolts 16 clamp the halves to the shaft. A split collar 17 is clamped together and to the hub by bolts 17a at a machined groove 17b in the hub to provide a location groove 18 for a stationary cutting blade unit 21. This assembly has a single blade 22 integral with a half ring 23. A second half ring 24 is clipped by interlocking formations 23a, 23b to the first half ring. The two half rings are accommodated in the location groove 18, with the interposition of thrust washers 18a, 18b.

Abstract: A method of designing a virtual model for the manufacture of a blended body structure having two or more constituent elements, the method comprising the step of defining a parameterised, theoretical procedural skin from which two or more datum skins are generated, each datum skin defining a production outline of an airframe structure constituent element. The use of a procedural model with embedded parameterisation and associativity to derive the datum skins reduces the time taken to produce the datum skins and enables feature modifications to be incorporated into models quickly and consistently.
