Abstract: A search extensibility application framework enables a hosted web search experience to be extended so that apps which are related to a search query can be presented to a user of a client computing device such as a smartphone. In various illustrative examples, a hosted search app is implemented using HTML5 code generated at a remote search provider server. Responsively to a user query at the search app's user interface (“UI”), the server returns an HTML5 payload including meta tags specifying criteria including app extension categories, actions, and known apps that support search terms in the query. Apps that are installed on the client device which match the criteria can then be displayed and launched through the UI to advantageously enable the users to complete a task specific search. JavaScript interfaces are provided to enable apps to update their install state and to be injected into the hosted search app.

If the shortcut indicates a search at the data source is desired, then a search is automatically performed at the data source.

Abstract: Systems and methods for controlling a modular three-phase converter including two or more interleaved, parallel connected Voltage Source Converters (VSCs) utilizing a hybrid Space Vector Pulse Width Modulation (SVM) control scheme are provided. For the hybrid SVM control scheme, six active vectors utilized for SVM define six sectors in a space vector plane. Each sector is divided into two or more regions having corresponding optimal SVM switching sequences. In operation, a revolving reference voltage vector is sampled to provide a reference voltage vector. The SVM controller then identifies one of the regions in one of the sectors that corresponds to an angle and, in some embodiments, a magnitude of the revolving reference voltage vector and applies the corresponding optimal SVM switching sequence to the two or more interleaved, parallel connected VSCs.

Abstract: A memory device that accurately tracks memory operations includes a vertical loopback for tracking a sense clock signal to a row address decoder, and read and write reference bit lines in a reference column that include loopbacks for vertically tracking a selected bit line during read and write operations. Preferably the widths of word lines and a sense line are equal to enable the sense line to horizontally track any selected word line. The memory device also includes tri-state input/output (I/O) latches to latch sense amplifier outputs. A drive circuit of the tri-state I/O latch is disabled when the output is available at the corresponding sense amplifier and enabled when the output is latched by the latch circuit.

The content may be variable, and may be filled in based on contextual information such as a search query string or user information. If the app is installed, then clicking, tapping, or otherwise activating the app may launch the app, possibly with context information being provided to the app. If the app is not installed, then a link to obtain the app may be provided.

Abstract: Techniques are described that can be used by a message engine to notify a core or hardware thread of activity. For example, an inter-processor interrupt can be used to notify the core or hardware thread. The message engine may generate notifications in response to one or more message received from a transmitting message engine. Message engines may communicate without sharing memory space.

Abstract: A system and method dynamically selects digital-to-analog (DAC) circuit elements to provide a True differential-output delta-sigma (??) DAC. The sign and magnitude of a received N-bit input code is determined. If the input code comprises a positive value, m+r circuit elements are selected from a plurality of circuit elements by a positive element selector, in which comprises a number of rotational elements, and r circuit elements are selected by a negative element selector. Each selected circuit element comprises a circuit element that was not selected for an immediately preceding received input code and has a corresponding minimum usage count value. If the input digital code comprises a negative value, m+r circuit elements are selected by the negative element selector, and r circuit elements are selected by the positive element selector. The circuit elements are capable of being configured as positive or negative circuit elements.

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.
