Abstract: A method and system for providing an electronic form are described. The method and system include identifying a visible portion of the electronic form. The electronic form can include a control component at a component location of the electronic form that is operable to receive an input from a user. The method and system can then determine an accessibility state of the control component based on the component location and at least one of a display property of the display and the visible portion. The accessibility state can be a convenient state when the component location is suitable for the display but is in an inconvenient state when the component location is not suitable for the display. When it is determined that the accessibility state is the inconvenient state, the method and system involves displaying a transient control component, or a version of the control component, on the display.

Abstract: A closed loop, active cancellation technique (ACT)-based RF power amplifier linearization architecture injects a pilot tone as a ‘pseudo distortion’ signal into signal paths through first and second matched RF amplifiers, and a set of power minimization loops are closed around the RF amplifier pair. The power minimizing control loops control a set of vector modulators such that both the injected pilot tone and intermodulation distortion products are canceled, while RF carrier components constructively sum in the composite output of the two RF amplifiers.
