Abstract: A system may include determination of a value of a radiation-related parameter, and changing of an operational parameter of a circuit based on the determined value. The radiation-related parameter may comprise an altitude of the circuit and/or a radiation level. In some aspects, the operational parameter may be a supply voltage and/or a period of a refresh cycle.

Abstract: A method, apparatus and system to enable a data processing device to operate while seemingly “off”. According to one embodiment, a data processing device is configured to recognize a new system state, i.e., Visual Off. On such a data processing device, when the power button is pressed, the request to turn off the device is intercepted by a module and the device is transitioned to a Visual Off state. To the user, this transition appears instantaneous. During the transition, audible and visual indicators on the data processing device and on human interactive devices (“HID devices”) coupled to the data processing device may be turned off and/or disabled. While in the Visual Off state, the device may be fully operational, or in an alternate embodiment, the device may be placed in a low power state. When the user presses the power button again to “wake up” the data processing device, the device may transition from Visual Off into an “on” state (“Visual On”), i.e.

Abstract: According to some embodiments, an opaque graphical user interface window is created when a display unit is in an off state.
