  • Efficient virtual function calls for compiled/interpreted environments
    Patent number: 7032230
    Abstract: Virtual function calls in hybrid compiled and interpreted computer programming environments are carried out efficiently by dual virtual function tables. Each class object generated is provided with a compiled virtual function table and an interpreted virtual function table. Each table is symmetrically structured and contiguous with the class object. Calls from an interpreted function access the interpreted virtual function table. Entries in that table point to function data structures which provide for the interpretation of the called function, or for transfer to execution of a compiled version of the called function. Calls from a compiled function access the compiled virtual function table. Entries in the compiled virtual function table point to either executable code representing the called function, or to transition code for transition to the interpreter to interpret the called function.
    Type: Grant

  • SILICON BASED NANOSPHERES AND NANOWIRES
    Publication number: 20060014018
    Abstract: Nanostructures and methods of fabrication thereof are disclosed. One representative nanostructure includes a silicon dioxide (SiO2)/tin oxide (SnOx) nanostructure, where x is between about 1 to about 2. The SiO2/SnOx nanostructure includes a SiO2 nanostructure having SnOx nanoclusters dispersed over a portion of the surface of the SiO2 nanostructure.

  • Tin oxide nanostructures
    Patent number: 6940086
    Abstract: Tin oxide nanostructures and methods of fabricating tin oxide nanostructures are disclosed. Representative nanostructures include SnO2 nanowires, SnO2 nanoribbons, and SnO2 nanotubes. Another representative nanostructure includes a nanostructure having a rutile crystal lattice and an orthorhombic crystal superlattice. The nanostructure can include, but is not limited to, SnO2 nanowires, SnO2 nanoribbons, and SnO2 nanotubes.
