  • Publication number: 20160093511
    Abstract: A multigate transistor device such as a fin-shaped field effect transistor (FinFET) is fabricated by applying a self-aligned diffusion break (SADB) mask having an opening positioned to expose an area of at least one portion of at least one gate stripe designated as at least one tie-off gate in the multigate transistor device and removing the tie-off gate through the opening of the SADB mask to isolate transistors adjacent to the tie-off gate.

  • Patent number: 9301375
    Abstract: A multi-strike ballast to ignite an electrodeless lamp is disclosed, and includes an inverter circuit, a protection circuit, and a controller. The inverter circuit, upon activation, sends an ignition pulse to the lamp. The inverter circuit shuts down upon receiving a deactivation signal, and activates upon receiving an activation signal, triggering another ignition pulse. The protection circuit senses a change in a voltage associated with the lamp. The sensed changed may indicate that the lamp has not yet ignited or that the lamp is broken. The controller receives the sensed change in voltage and, in response, sends a deactivation signal to the inverter circuit. The controller waits a predetermined time and then sends an activation signal to the inverter circuit. The controller repeats until a change in voltage associated with the lamp is not sensed, or until a predefined number of repeats occur, providing multiple ignition pulses to the lamp.

  • Patent number: 9270580
    Abstract: One embodiment of the present invention provides a system that facilitates traffic isolation (TI) in a network. During operation, the system configures a set of switch ports as members of a TI zone. The switch ports are part of an end-to-end path across one or more switch domains between a source and a destination. The switch ports within the TI zone and outside the TI Zone belong to a common storage area network (SAN) zone which compartmentalizes data for security purposes. The system then determines whether a data flow entering a switch domain belongs to the TI zone. The system subsequently forwards the data flow to the next port within the TI zone if the data flow belongs to the TI zone.

  • Patent number: 9268755
    Abstract: A method and apparatus for managing persistent change operations on user data is disclosed. For each change, a record of the change is saved. An index tracks the current state of the user data. Changes can be undone or redone in a sequential manner if certain criteria are met. Variables pertaining to the changes are saved in a persistent storage, enabling an undo/redo history to be preserved if a program is exited and restarted.

  • Patent number: 9270727
    Abstract: Disclosed are various embodiments for facilitating access to data in network page generation code supplied by customers of a hosting provider. A request for a network page is obtained from a client. The network page is associated with a network site hosted by a hosting provider on behalf of a customer. Page generation code supplied by the customer is obtained, and this code includes a dynamic data variable. One or more service calls are executed based at least in part on the dynamic data variable to obtain one or more data objects. The page generation code is executed to generate the network page in response to the request, where the page generation code is executed with the data objects in place of the dynamic data variable.

  • Patent number: 9262421
    Abstract: An efficient large scale search system for video and multi-media content using a distributed database and search, and tiered search servers is described. Selected content is stored at the distributed local database and tier1 search server(s). Content matching frequent queries, and frequent unidentified queries are cached at various levels in the search system. Content is classified using feature descriptors and geographical aspects, at feature level and in time segments. Queries not identified at clients and tier1 search server(s) are queried against tier2 or lower search server(s). Search servers use classification and geographical partitioning to reduce search cost. Methods for content tracking and local content searching are executed on clients. The client performs local search, monitoring and/or tracking of the query content with the reference content and local search with a database of reference fingerprints.

  • Publication number: 20160034452
    Abstract: The overall architecture and details of a scalable video fingerprinting and identification system that is robust with respect to many classes of video distortions is described. In this system, a fingerprint for a piece of multimedia content is composed of a number of compact signatures, along with traversal hash signatures and associated metadata. Numerical descriptors are generated for features found in a multimedia clip, signatures are generated from these descriptors, and a reference signature database is constructed from these signatures. Query signatures are also generated for a query multimedia clip. These query signatures are searched against the reference database using a fast similarity search procedure, to produce a candidate list of matching signatures. This candidate list is further analyzed to find the most likely reference matches. Signature correlation is performed between the likely reference matches and the query clip to improve detection accuracy.

  • Patent number: 9251361
    Abstract: Techniques for transmitting data to an entity may be provided. In particular, a location of a data file (e.g., image, text, multimedia file, document, blog entry, identifying user information) can be provided to a location of a transitive file storage device for the entity to retrieve, instead of providing the data file directly to the entity. The entity can then provide the data file to users (e.g., via a hosted network page) and/or provide the data file to a service provider along with code to enable the service provider to provide the data file to users.
