Publication number: 20160070461Abstract: A Method for a measurement system, wherein the measurement system includes a touch-screen, a control-unit for the touch-screen, a measurement hardware, a measurement application and a gesture detection unit, wherein the measurement application interacts with the measurement hardware. In a first step the control-unit detects a position and/or a movement of one or more physical objects on and/or near the touch-screen. In a second step the gesture detection unit assigns the position and/or the movement of one or more physical objects to one gesture within a set of gestures. In a third step the gesture detection unit communicated the detected gesture to the measurement application. Furthermore, the measurement application performs a different function for the same detected gesture depending on a user interface of the measurement application which is displayed on the touch-screen when the gesture is detected.Type: ApplicationFiled: April 8, 2013Publication date: March 10, 2016Inventors: Wolfgang HERBORDT, Friedrich REICH, Barry ROWLAND, Rene MUESSIG

Patent number: 9075108Abstract: A method for marking a signal edge, which has been removed from at least one decimated binary signal after the decimation of an associated binary signal, within the decimated binary signal, establishes successive signal portions of the respective binary signal, in each case with a number of sampled values corresponding to a decimation factor of the decimation. It detects a signal edge removed through decimation from each signal portion if the number of signal edges determined in each signal portion of the respective binary signal is greater than one. Then, the sampled values of the respective decimated binary signal are determined through decimation of the sampled values of the associated binary signal with the decimation factor, and the removed signal edge at the sampling time of the decimated binary signal which corresponds to the signal portion of the associated binary signal with the signal edge removed through decimation is marked.Type: GrantFiled: July 19, 2011Date of Patent: July 7, 2015Assignee: Rohde & Schwarz GmbH & Co.
