Live migration of partitions
Live migration of partitions can be achieved using server-to-server communications to coordinate and control partition migration and rebuild a persistent state of the partition on a destination server while the partition is served on the source server. The live migration approach breaks the heavy dependency on the partition master by eliminating most of the server-to-master communications, delegating coordination and control of the migration to the source and destination servers. After the migration is initiated by the partition master, the source server sends in-memory cache entries indicating the persistent state of the partition to the destination server. Once transferred, the two servers can cooperate to complete the handover, which loads the partition on the destination server using the cache entries received from the source server. Once the source server offloads the partition, it can redirect traffic for the partition to the destination server by triggering an update to the partition map. |

Method and system for transferring data to improve responsiveness when sending large data sets
Most of the internet traffic today is carried out via the Transmission Control Protocol (TCP).

Identification of unknown altered versions of a known base media item
Small changes in a broadcast version of a base media item can be identified by performing a multi-level comparison of digital fingerprints. A fingerprint of a base media item is compared to a fingerprint of a media broadcast to determine whether a media item embedded in a broadcast is likely, to a first level of certainty, to be the base media item. A second, more stringent, match between the fingerprint of the base media item and loosely matched items can be used to identify potentially-altered versions of the base media item. Potentially-altered versions can be compared against each other, and resulting matches are flagged as altered base media items, which can be fingerprinted and tested against broadcast fingerprints in the same manner as the base media item. Comparisons are made in parallel between two fingerprints to distinguish between a known base media item and unknown altered versions of the known base media item without prior storage of the unknown altered versions of the known base media item. |

Self-powered electronic fuse
A two-terminal electronic fuse device involves two switches, four diodes, switch control circuitry, and a storage capacitor, connected in a particular topology. When AC current flows through the fuse, a charging current charges the storage capacitor. Energy stored in the storage capacitor is then used to power the switch control circuitry. If the voltage on the storage capacitor drops, then the switches are opened briefly and at the correct time. Opening the switches allows the charging current to flow. By opening the switches and charging the storage capacitor only at times of low current flow through the fuse, the disturbance of load current flowing through the fuse is minimized. If an overload current condition is detected, then the fuse has tripped and first and second switches are opened. If the capacitor does not need charging and there is no overload condition, then the switches remain closed. |

Hybrid microelectronic substrate and methods for fabricating the same
A hybrid microelectronic substrate may be formed by the incorporation of a high density microelectronic patch substrate within a lower density microelectronic substrate. The hybrid microelectronic substrate may allow for direct flip chip attachment of a microelectronic device having high density interconnections to the high density microelectronic patch substrate portion of the hybrid microelectronic substrate, while allowing for lower density interconnection and electrical routes in areas where high density interconnections are not required. |

MOS antifuse with void-accelerated breakdown
A MOS antifuse with an accelerated dielectric breakdown induced by a void or seam formed in the electrode. In some embodiments, the programming voltage at which a MOS antifuse undergoes dielectric breakdown is reduced through intentional damage to at least part of the MOS antifuse dielectric. In some embodiments, damage may be introduced during an etchback of an electrode material which has a seam formed during backfilling of the electrode material into an opening having a threshold aspect ratio. In further embodiments, a MOS antifuse bit-cell includes a MOS transistor and a MOS antifuse. The MOS transistor has a gate electrode that maintains a predetermined voltage threshold swing, while the MOS antifuse has a gate electrode with a void accelerated dielectric breakdown. |

Conductive trace design for smart card
A lead frame for assembling a smart card is formed with a substrate having first and second opposing major surfaces. A die receiving area is formed in the first major surface of the substrate and surrounded by conductive vias. A conductive coating is formed on the second major surface of the substrate and patterned to form electrical contact pads over the conductive vias. A conductive trace is formed on the first major surface of the substrate. The conductive trace extends between at least two adjacent vias and partially surrounds the at least two adjacent conductive vias, thereby forming a gap in the portion of the trace that surrounds the vias. An electrical connection between an integrated circuit chip and the conductive via extends over the gap. The gap prevents the electrical connection from inadvertently contacting the conductive trace. |
