  • Patent number: 8777086
    Abstract: A bonding tool is adjusted to a desired operational position by viewing the bonding tool with an image-capturing device and displaying an image of the bonding tool as viewed by the image-capturing device onto a display screen. A corresponding image of a reference bonding tool showing the desired operational position of the bonding tool is superimposed onto the display screen and the position of the bonding tool is adjusted with an adjustment mechanism until the bonding tool as viewed by the image-capturing device is aligned with the superimposed image of the reference bonding tool.

  • Patent number: 8698492
    Abstract: Methods for testing for defects on magnetic media storage disks are provided. One such method includes dividing a surface of a magnetic media disk into a plurality of radial zones, dividing the disk surface into a plurality of concentric zones, thereby forming a preselected number (N) of wedge subsections for each of the concentric zones, scanning the disk surface for defects, counting the defects contained within each of the wedge subsections, summing the defects contained within two or more of the wedge subsections, comparing the summed defects with a preselected threshold, and determining, based on the comparison, a defect type of the disk.

  • Patent number: 8483027
    Abstract: A disk drive is disclosed comprising a disk including a plurality of tracks, a head coupled to an actuator arm actuated over the disk, and control circuitry operable to first seek the head from a first track to a second track, read data from the second track to generate a first read signal, second seek the head from the second track to a third track, read data from the third track to generate a second read signal, third seek the head from the third track to a fourth track, and read data from the fourth track to generate a third read signal. The first, second, and third read signals are evaluated to qualify the disk drive, wherein the first, second, and third seeks are executed in proximity so as to excite the actuator arm with a jitter motion.

  • Publication number: 20120115046
    Abstract: The present invention refers to an electrode comprised of a first layer which comprises a mesoporous nanostructured hydrophobic material; and a second layer which comprises a mesoporous nanostructured hydrophilic material arranged on the first layer. In a further aspect, the present invention refers to an electrode comprised of a single layer which comprises a mixture of a mesoporous nanostructured hydrophobic material and a mesoporous nanostructured hydrophilic material; or a single layer comprised of a porous nanostructured material wherein the porous nanostructured material comprises metallic nanostructures which are bound to the surface of the porous nanostructured material. The present invention further refers to the manufacture of these electrodes and their use in metal-air batteries, supercapacitors and fuel cells.

  • Patent number: 6017694
    Abstract: Methods of screening for modulators of respiratory syncytial virus matrix protein interaction are described. A host cell carrying a nucleic acid sequence encoding RSV matrix protein or fragments of RSV matrix protein which can bind to RSV matrix protein is cultured and the RSV matrix protein or RSV fragments are expressed. The interaction of the expressed RSV matrix protein or fragments is measured. A test sample is then added to the expressed RSV matrix protein or fragments and the effect of the test sample on RSV matrix protein interaction is measured.
