  • Publication number: 20090287910
    Abstract: According to a particular embodiment, an imaging system is provided that includes an imaging device operable to image a hard-drive of a target device. The imaging device includes a first connection to the target device and a second connection to an output capture device, whereby both connections facilitate an information flow of data. The imaging device includes a preprogramming element that includes a stored version of preprogramming instructions, which direct the imaging device on how to image the hard-drive autonomously. In more specific embodiments, the instructions are triggered when the imaging device is powered ON. The instructions can verify the first connection to the hard-drive and the second connection to the output capture device. The instructions can include a template that reflects a loaded routine for imaging the hard-drive based on a particular imaging job.

  • Patent number: 6538080
    Abstract: A gas phase fluidized bed process is described for producing ethylene polymers having improved processability and an MWD of less than about 2.9. Multiple reactors in series or parallel may be used to produce in-situ blended polymers. Each reactor can separately have a constrained geometry catalyst or a conventional Ziegler-Natta catalyst as needed for obtaining in-situ blended polymer with the desired properties as long as there is a constrained geometry catalyst in at least one reactor. Olefin polymers can be produced according to this invention which have low susceptibility to melt fracture, even under high shear stress conditions.
