Abstract: An electronic apparatus includes a battery holder, a detector detecting a battery, a non-volatile memory storing a program for initialization, a volatile memory, a first power supply for the non-volatile memory, a second power supply for the volatile memory, a power switch, a power supply controller activating the first power supply and the second power supply after the battery is detected or after the power switch is turned on, and a management circuit sending the program from the non-volatile memory to the volatile memory if the first and the second power supplies are activated and before the program is fully sent to the volatile memory, causing the power supply controller to deactivate the first power supply after sending the program, and causing the program in the volatile memory to run after the power switch is turned on.

Abstract: A data processing apparatus capable of detecting an object being in contact with a portion thereof is provided. The data processing apparatus includes a display, a tactile sensor and a controller. The tactile sensor is configured to detect the object and to locate the object on a sensing surface thereof. The controller is coupled to the display and the tactile sensor, configured to locate an initial location of the object on the sensing surface if the object starts being detected, and configured to locate a final location of the object on the sensing surface if the object ends being detected. The controller is configured to select a scroll direction depending on a direction from the initial location to the final location. The controller is configured to select a scroll speed, and configured to scroll a screen displayed on the display in the scroll direction at the scroll speed.
