Abstract: An electronic apparatus comprising an environment sensing device, a display, a touch sensing device, and a processing module comprising a main controller and a sub-controller is disclosed. The main controller performs a predetermined function based a touch input. The sub-controller computes a tilt angle of the electronic apparatus, and activates the touch sensing device without turning on the display if the tilt angle falls in a predetermined angle range, while the main controller is in the sleep mode. The processing module performs following steps when the display is off: determining the touch input is valid or invalid; keeping the display off if the touch input is invalid. The sub-controller wakes and activates the main controller to turn on the display and to control the electronic apparatus to perform the predetermined function according to a gesture formed by the touch input if the touch input is valid.

Abstract: A touch input determining method applied to an electronic apparatus with a touch sensing device, which comprises: (a) determining a size for a region of the touch sensing device that an object provides at least one touch input to; (b) if the size is larger than or equals to a first predetermined value, not determining the touch input is a valid touch input; and (c) if the size is smaller than or equals to a second predetermined value, not determining the touch input is a valid touch input, wherein the second predetermined value is smaller than the first predetermined value.

Abstract: Memory management methods and systems for page-out mechanism are provided. A page-out mechanism is performed via an OS (Operating System) based on a parameter of the page-out mechanism, wherein the page-out mechanism moves data from a memory to a storage unit. A usage of a page-out partition in the storage unit is monitored. The parameter of the page-out mechanism is dynamically set according to the usage of the page-out partition, wherein when the usage is increased, the parameter of the page-out mechanism is decreased, and when the usage is decreased, the parameter of the page-out mechanism is increased.
