  • Patent number: 7954086
    Abstract: A method, and a corresponding mechanism, are used for creating a self-describing kernel module. The method includes the steps of expressing data describing a module in a modmeta file format and creating a C language source file. The C language source file is created by translating the expressed data into a series of C language data structures, wherein the series of C language data structures comprises the C language source file. The C language source file is then compiled and linked into the module itself, thus making the module contain its own descriptive data.

  • Patent number: 5156486
    Abstract: A traffic control marker and marker base is described taking the form of a dome-shaped resilient body member whose ends lie in a flat plane and whose sides are outwardly flared. The marker can be formed by cutting a used pneumatic tire into arcuate segments, each of which can be forcefully inverted to automatically provide such body member. In many circumstances, the bodies alone, colored with eye-catching fluorescent or reflective coatings, can be effectively used for traffic control markers. And in other circumstances they can serve as a resilient light-weight base whereon various visual indicators such as a flag, sign, reflector, or light can be removably mounted in various ways to rise therefrom.
