  • Method and system for testing address lines
    Patent number: 7532526
    Abstract: Method and systems are described for testing an address line inter-coupling a processor and a memory. The contents of a first address in the memory are initially compared with the contents of a second address in the memory, wherein each of the first and second addresses are addressable in the memory by a different value applied on the address line. If the contents of the first and second addresses match, the contents of either one of the first and second addresses are changed, and a subsequent comparison of the contents of the first and second memory addresses is performed. If the second comparison determines that contents of the first and second memory address still match, then a fault condition associated with the address line is identified.

  • Method of determining similar attributes between one or more users in a communications network
    Publication number: 20090030886
    Abstract: A method of determining similar attributes between one or more users in a communications network (100) including the steps of: (a) determining (S305) one or more attributes of one or more users on a communications network; (b) comparing (S310) the one or more attributes of the one or more users on the communications network; (c) using (S315) an inference filter to determine the one or more attributes in common with the one or more users; and (d) representing (S320) the one or more users which have one or more attributes in common on a display.
