An energy storage level indication circuit includes an energy storage device and a radio control module operable to transmit a wireless heartbeat signal at a rate indicating an amount of energy stored in the energy storage device. The system starts by generating a vibration at a predetermined frequency in a computer system. This provides resistance to static attacks by transforming the original function-call layout to a new layout. As one example, the trigger may include a Uniform Resource Locator in the form of a tv: protocol that automatically causes the television display to go to full screen television. The base plate has a base-side retaining section for retaining the insulating slope member. The housing includes an opening that allows the heat-exchange core bundle to be housed inside the housing.
