摘要:
Button action in a display system is dynamically denoted by either illuminating or not illuminating an illuminable element adjacent to the button to provide a lighting effect around the periphery of the button. The illumination of an illuminable element adjacent to an active button has the effect of drawing attention to an active button. Active buttons are dynamically updated based upon the state of the system and/or the particular page displayed.
摘要:
A heat exchanger particularly intended for condensing vapor from a gaseous stream in which there are provided fins so disposed that condensate forming on the fins drips onto one side only of the fins below it. This reduces the deleterious effect of the build-up of a liquid layer on fins which liquid layer reduces the thermal effectiveness of the fins.
