Abstract: Systems, methods, and devices perform interference cancellation operations for wireless devices. Methods include transmitting an input signal using a transmitter of a transceiver included in a wireless device, receiving an interference signal at a receiver of the transceiver, wherein the interference signal is a leakage signal, and performing interference cancellation operations on the interference signal based, at least in part, on one or more adjustments to the receiver determined based on the input signal and the received interference signal. Methods further include generating, using the transceiver, an output signal based, at least in part, on the interference cancellation operations.

Abstract: Various embodiments discussed herein are directed to improving existing technologies by enabling users to share content items directly from an operating system component, with little to no user interface input requirements at the underlying communications application. For instance, some embodiments receive an indication that a mouse pointer is hovering over an operating system taskbar icon and automatically produce a flyout window so that a user can share a currently opened application page to other users via a selection of a button within the flyout window. Such application page may be shared via a single selection at the flyout window or an additional “are you sure” or confirmation step. In this way, excessive drilling, navigation, and other user input at the application is reduced and simplified, thereby improving the user experience, content sharing accuracy, and computer resource consumption, among other improvements.

The inverter is configured to receive a DC input from the DC power source and output an alternating current (AC) to three phases of a motor. The system also includes a single current sensor arranged to sense a current from the DC power source to the inverter and a control unit that controls the operation of the switching elements based in part on an output of the single current sensor. A control unit controls the operation of the switching elements based in part on an output of the single current sensor. The control unit is configured to determine that a Hall sensor change has occurred and to control the operation of the switching elements based on a prior sensor reading for a time period (tblanking) after the Hall sensor change.

Abstract: Described herein is a system and method for detecting a layout table by a screen reader. Information regarding a document being displayed by an application is received from an application programming interface of a user interface automation system that provides information regarding user interface elements of application and/or the application. The information includes an indication that the document comprises a table. A determination is made as to whether the table is a data table or a layout table based upon the received information using a rule-based heuristic. When it is determined that the table is a layout table, presentation information associated with the layout table can be skipped over, and, cell data content within the layout table provided. Thus, for a determined layout table, the system and method allow the screen reader to act as if the containing table doesn't exist, but still read the content.

Abstract: Described herein are systems and methods for determining a logical starting location to start providing (e.g., reading) content to a user. When the user navigates to a particular web page and/or email message, a screen reader can automatically read content associated with the web page and/or email message beginning at the determined logical starting location. A heuristic can be applied in order to determine the logical starting location. The heuristic can analyze information regarding user interface element(s) (e.g., property(ies) and/or attribute(s)) of the particular webpage and/or email message to find a logical location to start reading once the webpage and/or email message have loaded.

Abstract: Described herein is a screen reader system for providing contextually relevant information for ambiguous link(s). Input is received from a user requesting information about a particular link of a web page. In response to the received user input, a request for contextually relevant information regarding the particular link (e.g., page identifier) is provided to a search engine. The request can include a uniform resource locator (URL) associated with the particular link. Contextually relevant information regarding the particular link is received from the search engine. The received contextually relevant information is provided (e.g., displayed and/or read) to the user in response to the received request for information.
