Abstract: An electronic system test method, comprising: (a) inputting a victim test pattern to a victim signal path of a target electronic system and simultaneously inputting at least one aggressor test pattern to at least one aggressor signal path of the target electronic system, according to a major set of test patterns comprising a plurality of minor set of test patterns; (b) acquiring a output response corresponding to the step (a); and (c) after changing the victim test pattern or the aggressor test pattern, and after repeating the step (a) and the step (b) until all of the major test patterns set are used thereby acquiring a plurality of the output responses, determining a combination level according to the output responses. The victim test pattern is an X bit pattern and the aggressor test pattern is a Y bit pattern, X and Y are positive integers larger than or equal to 3.

Abstract: The present disclosure proposes a power management method for use by a handheld mobile electronic device having a display and a device using the same. The method may include when the display darkens as the result of not receiving input signal after a first predetermined period, the screen brightness would be restored back to the original brightness in response to receiving a sensor output generated by a specific movement of the handheld mobile electronic device. Otherwise, when the touch screen darkens as the result of activating a key of the handheld mobile electronic device, the display will not respond to sensor output generated by the specific movement of the handheld mobile electronic device.
