  • Patent number: 6040878
    Abstract: Hook- and loop-type tapes are selectively attached to a video display unit and to flexible elongated strips of magnetic material so that the strips of magnetic material may be removably mounted around the video display unit in orthogonally intersecting planes to absorb magnetic radiation from the source. Each strip of magnetic material has a grain orientation parallel to its longitudinal axis and may be formed from grain-oriented ferromagnetic material in the range from M3 to M7. A multiple-layer magnetic shielding material is provided by securing first and second layers of such grain-oriented ferromagnetic material together with the grain orientation of the first layer orthogonal to the grain orientation of the second layer. Each strip of magnetic material may also be formed from this multiple-layer magnetic shielding material.

  • Patent number: 5361351
    Abstract: The present invention is directed to computer software compilation systems and methods which support run-time data type identification of objects in computer programming languages which support polymorphism. The present invention comprises translators, compilers, and debuggers. The compiler and translator store modified debug information in an object code file. The modified debug information contains information regarding either multiple virtual tables or concatenated virtual tables. A debug lookup table is constructed from the modified debug information. The debugger uses the debug lookup table to determine the actual data types of the objects, and to completely and accurately display and modify the objects' contents. Also, innovative type inquiry operators reference the concatenated virtual tables to determine the actual data types of the objects during run-time. The operation of the compiler, translator, and debugger is transparent to computer programmers and operators.

  • Patent number: 5339440
    Abstract: The present invention provides a protocol method for waiting the bus in a digital computer and an apparatus for implementing that protocol. By allowing the bus to continue running after a wait command has been asserted, modules on the computer bus are not required to respond instantly to the wait command. Information on the bus during the multiple cycles of the wait period is defined as invalid and valid data is driven on the bus after the wait period has expired. Bus driver modules are provided with a replay queue to replay, on the bus, data the driver module drove on the bus during the wait period if required.
