  • System for repair of ROM programming errors or defects
    Publication number: 20050039071
    Abstract: A system is disclosed for use of imperfect ROMs in embedded systems. The ROM or other memory accessible upon start-up of the system, includes a stored program which checks an external source to determine whether any of the information in the ROM should be replaced. If it should be replaced, then the system retrieves good information from an external source and stores it into a cache memory. By setting a “lock” bit, erasure of the replacement information is prevented.

  • Circuit group design methodologies
    Publication number: 20050028128
    Abstract: A group based design methodology and system. In one embodiment the groups have predefined layout characteristics and are sometimes amalgamated into functions. Integrated circuits are designed by placing groups and functions into a layout space.

  • Start-up procedure for multiple catalyst polymerization systems
    Patent number: 6620894
    Abstract: This invention relates to a method to start up an olefin polymerization process comprising: a. calculating a trajectory, from elements including catalyst deactivation rate constants (kd), for the rate of introduction of a catalyst system, into a reactor, said catalyst system comprising two different metal catalyst compounds (A and B) and at least one activator, wherein the ratio of the deactivation constants of the two different metal catalyst compounds kdA/kdB is not 1; and b. introducing olefin monomer, a catalyst system, optional co-monomer, and optional chain transfer or termination agents into a polymerization reactor in a manner such that the catalyst system introduction rate is manipulated to follow the trajectory until a desired production rate is achieved.
