Abstract: A method, computer system and computer readable medium regarding an extensible master-slave user interface with distinct interaction models is presented. A slave region is displayed in a Graphical User Interface (GUI), the slave region displaying a current state. A master region is displayed in the GUI, the master region displaying a previous state. When a user selects content in the slave region then the master region is removed from the GUI, a new master region is displayed in the GUI, the new master region containing a view of contents of the slave region, the slave region is removed from the GUI and the content selected by the user is displayed in a new slave region in the GUI.

Abstract: A technique includes providing a plurality of local oscillator signals such that each of the local oscillator signals has a different phase. The technique includes providing scaling units to scale the input signal pursuant to different scaling factors to generate scaled input signals. The scaling factors are selected on a periodic function of the phases. The technique also includes providing mixing circuits to mix the local oscillator signals with the scaled input signals to generate mixed signals and providing an adder to combine the mixed signals to generate an output signal.

Abstract: A method for locating a portion of data is provided. In this method, a request for a Uniform Resource Locator (URL) associated with data is transmitted. The request comprises a labeling tag that is associated with the data. As a result of the request, an URL that comprises an anchor identifier is received and the data located at the URL are retrieved. An anchor within the data is located based on the anchor identifier and a portion of data is located based on the location of the anchor.
