  • Patent number: 7985640
    Abstract: Symmetrical/asymmetrical bidirectional S-shaped I-V characteristics with trigger voltages ranging from 10 V to over 40 V and relatively high holding current are obtained for advanced sub-micron silicided CMOS (Complementary Metal Oxide Semiconductor)/BiCMOS (Bipolar CMOS) technologies by custom implementation of P1-N2-P2-N1//N1-P3-N3-P1 lateral structures with embedded ballast resistance 58, 58A, 56, 56A and periphery guard-ring isolation 88-86. The bidirectional protection devices render a high level of electrostatic discharge (ESD) immunity for advanced CMOS/BiCMOS processes with no latchup problems. Novel design-adapted multifinger 354/interdigitated 336 layout schemes of the ESD protection cells allow for scaling-up the ESD performance of the protection structure and custom integration, while the I-V characteristics 480 are adjustable to the operating conditions of the integrated circuit (IC).

  • Patent number: 7980671
    Abstract: The present application is directed to electrostatic actuators, and methods of making electrostatic actuators. In one embodiment, an electrostatic actuator of the present application comprises a first electrode and a second electrode. The second electrode is positioned in proximity to the first electrode so as to provide a gap between the first electrode and the second electrode. The first electrode is capable of being deflected toward the second electrode. A dielectric structure comprising a dielectric landing post is positioned in the gap between the first electrode and the second electrode, the dielectric structure extending over a greater surface of the gap than the landing post. The landing post protrudes out into the gap so as to limit the minimum contact spacing between the first electrode and the second electrode.

  • Patent number: 7979643
    Abstract: Embodiments of the present invention provide methods and systems for tuning the size of the cache. In particular, when a page fault occurs, non-resident page data is checked to determine if that page was previously accessed. If the page is found in the non-resident page data, an inter-reference distance for the faulted page is determined and the distance of the oldest resident page is determined. The size of the cache may then be tuned based on comparing the inter-reference distance of the newly faulted page relative to the distance of the oldest resident page.

  • Patent number: 7978403
    Abstract: Exemplary embodiments provide an image interferometric microscope (IIM) and methods for image interferometric microscopy. The disclosed IIM can approach the linear systems limits of optical resolution by using a plurality of off-axis illuminations to access high spatial frequencies along with interferometric reintroduction of a zero-order reference beam on the low-NA side of the optical system. In some embodiments, a thin object can be placed normal to the optical axis and the frequency space limit can be extended to about [(1+NA)n/?], where NA is the numerical-aperture of the objective lens used, n is the refraction index of the transmission medium and ? is an optical wavelength. In other embodiments, tilting the object plane can further allow collection of diffraction information up to the material transmission bandpass limited spatial frequency of about 2n/?.

  • Patent number: 7963694
    Abstract: A temperature sensitive label may be affixed to a temperature sensitive item. The temperature sensitive label conveys when the item has reached a tripping temperature. The tripping temperature may be a temperature at which the item is compromised. To convey this, the label changes properties and functions with a message to convey that the item has been exposed to the tripping temperature. For example, the label may reveal, block, or alter a message that conveys whether the item has been exposed to the tripping temperature. The message may be part of the label or separate from the label.

  • Patent number: 7961905
    Abstract: A printed image can be redundantly encoded by printing a visible image using a colorant with a luminance that contrasts with that of the output sheet and printing a redundant image using a colorant with a luminance that varies only slightly from that of the output sheet. Accordingly, the visible image can be easily read by a user while the redundant image is substantially invisible to the human eye at normal reading distances, yet capable of being captured by a conventional digital scanner. In one aspect, redundantly encoded images may be printed on a white background, with visible images printed in black text and redundant images printed in blue in content regions of the visible image and in yellow in its background regions.

  • Patent number: 7962765
    Abstract: Embodiments of the present invention provide a tamper proof file system. In particular, the present invention utilizes a virtual block device that is coupled with a real block device and a private/public key pair. The virtual block device receives the original data and then digitally signs it with the private key. The virtual block device then passes the digitally signed data to the real block device for storage. In order to retrieve or verify the data, the virtual block device may provide the public key and an acknowledgment. The acknowledgment may include a hash of the public key. The virtual block device is configured to discard the private key and to be removed from the system based on a finite lifespan.
