Abstract: A radio transmit-receive unit can perform the communication processing stably without being affected by high frequency noise with the system activation of a computer unit, whereby if a communication processing request from the radio transmit-receive unit occurs, the computer unit sets the system state of a sub-CPU being activated to a rest state, a counter starts clocking the signal receive time of the radio transmit-receive unit when the system state of the sub-CPU is in a rest state, and a latch circuit holds electric field strength information of carrier received by the radio transmit-receive unit upon the termination of clocking by the counter. And the computer unit switches the system state of the sub-CPU being at rest to an active state, based on the end state of clocking by the counter, to restart the activation of the computer unit.

Abstract: A computer display system includes a display screen capable of flipping between portrait orientation and landscape orientation and includes a method for repositioning and resizing display windows in response to flipping between such oprientations of the display screen. The windows are moved and resized according to a set of rules to yield displays which take advantage of the new orientation. Where the computer display system includes coordinated, multiple display screens, images controlled for display on fixed-orientation display screens do not change as a result of a flip between orientations of a variable-orientation display screen.
