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 hydrogen generator comprising an enclosure, a series of spaced plates contained within the enclosure and defining between them liquidtight cells, with a plate forming a first wall of each cell of a nobler material than a plate forming a second wall of that cell, and where a first place of the series is an anode arranged to be connected to a power supply and the last plate of the series is a cathode arranged to be connected to a power supply, an inlet to each cell arranged to allow an electrolyte to flow into the cell, and an outlet from each cell arranged to allow an electrolyte and hydrogen gas to flow out of the cell.
