  • Publication number: 20130343133
    Abstract: A system for detecting soft errors in a memory device includes a latch, a master flip-flop and a slave flip-flop. The latch receives input data (control and/or address signals) at the beginning of a memory operation in response to a rising edge of a first clock signal. The output of the latch is provided to the master flip-flop. The master flip-flop continuously receives and stores the latch output during the memory operation based on a second clock signal. The slave flip-flop receives and stores the output of the master flip-flop at the end of the memory operation based on the second clock signal. A comparator compares the input data with the output of the slave flip-flop to detect soft errors that occur during the memory operation.

  • Publication number: 20130336297
    Abstract: Incorporating and operating a mesh base station in a wireless network is described. The mesh base station can utilize common wireless resource allocations as a corresponding wireless base station while transmitting to wireless subscriber stations during the same time period. The mesh base station obtains a data packet from the wireless base station over a backhaul link during a scheduled time period and transmits the data packet to the designated wireless subscriber station during another scheduled time period. The wireless base station and the mesh base station can also receive data packets from wireless subscriber stations during a same time period. A wireless network can be configured with two mesh base stations at an approximate boundary of two adjacent sector coverage areas, where a coverage area is supported by a wireless base station and each mesh base station supports wireless subscriber stations within a coverage radius.

  • Patent number: 8595370
    Abstract: A technique is provided for providing a trust indicator for a particular webpage. The trust indicator may indicate whether publishers of web content and/or end-users trust the content of the particular webpage and whether the particular webpage is popular. A user requests, via a web browser a webpage to be displayed. A process associated with the webpage requests a value to be displayed along with the webpage. The value may indicate 1) a number of links that link to the webpage, 2) a number of user-created tags that have been associated with the webpage, or 3) a trust rank that a web crawler associates with the webpage. A trust rank may be based, at least in part, on user-created tags that have been associated with the webpage. A value may also be associated with an advertisement that is displayed along with a particular webpage.

  • Patent number: 8587975
    Abstract: A Dual Active Bridge (DAB) converter and a Pulse Width Modulation (PWM) scheme for controlling the DAB converter are disclosed. In general, the DAB converter includes a transformer, a first H-bridge that is connected to a primary winding of the transformer and controlled via first control signals, and a second H-bridge that is connected to a secondary winding of the transformer and controlled via second control signals. A controller provides the first and second control signals based on an input-to-output voltage ratio and load of the DAB converter such that, in addition to phase shift control, PWM control is simultaneously applied to both the first H-bridge and the second H-bridge when the DAB converter operates at low power and PWM control is applied to only one of the first H-bridge and the second H-bridge when the DAB converter operates above low power.

  • Publication number: 20130304718
    Abstract: An application (“app”) may be associated with a web site, so that an online service may use the connection between the app and the web site. In one example, the online service is an information provider, such as a search engine or advertising engine. The online service provides a web administrator portal, through which a webmaster provides or generates a secret code. The webmaster gives the secret code to an app developer, who gives the code to an app store when the app is published. If the service provides information about the web site (e.g., as a search result or ad impression), the service may also provide an indication of the app, since the use of the code represents confirmation by both the webmaster and app developer that a relationship exists between the web site and the app.

  • Publication number: 20130268507
    Abstract: Among other things, one or more techniques and/or systems are provided for facilitating the completion of a user task. That is, user intent (e.g., intentions of a user to perform a user task) may be identified. The user intent may comprise an entity (e.g., a movie entity) and/or an action (e.g., an order movie tickets action) that the user wants to perform on the entity. A provider list may be created based upon one or more providers capable of performing the action on the entity (e.g., a movie application may be capable of performing the order movie tickets action on the movie entity). Providers may be dynamically selected for inclusion within the provider list at run-time. For example, an open market of providers may be maintained (e.g., providers may be added, removed, and/or updated over time), such that providers may be selected from the open market to complete user tasks.

  • Patent number: 8547931
    Abstract: Conserving call logic during handoff may be provided. First, a call may be received at a first server. Next, the first server may determine that it cannot handle the call. Then the call may be transferred by the first server to a second server with enough information so that the second server can take up the call where the first server left off. Transferring the call to the second server with enough information so that the second server can take the call up where the first server left off may comprise placing the information in a REFERRED-BY header and sending the REFERRED-BY header to the second server.

  • Patent number: 8543518
    Abstract: A method and a system are provided for deducing shadow user profile attributes for ad campaigns aimed at target users. In one example, the system extracts tagged data from source data. The tagged data includes label information associated with an actual profile for a user. The tagged data is associated with the user. The system prepares the tagged data by splitting the tagged data into datasets, including at least training data and test data. The system generates one or more individual models based on the tagged data, wherein the one or more individual models provide the ability to deduce attributes of a profile for the user. The system then generates a composite model based on the individual models. The composite model includes a combination of the individual models that are associated with the user. The system may charge a premium for ad campaigns that are aimed at target users who are each assigned one or more shadow profile attribute values.
