Electronic apparatus and disk protection method
View Patent ↗An electronic apparatus includes a body, a triaxial acceleration sensor which is built in the body and includes a long axis and a short axis, a disk device built in the body, a calculation unit that calculates a value on a basis of an acceleration value which is detected by the triaxial acceleration sensor and is output in a direction perpendicular to the long axis and to the short axis, a setting unit that sets a threshold in a state of the body in which a plane formed by the long axis and the short axis is approximately parallel to a direction of action of gravitational acceleration, and a controller that starts protection of the disk device on a basis of a result of comparison between the value calculated by the calculation unit and the threshold.
1. An electronic apparatus configured to have power-supplied to it by an AC adaptor or a battery, the electronic apparatus comprising:
a body;
an acceleration sensor configured to detect an acceleration applied on the body;
a disk device built in the body and configured to store
data;
a disk protection module configured to:
detect a vibration based on the acceleration detected by the acceleration sensor and a detection sensitivity; and
execute a protection function to protect the disk device in accordance with a detected result of the vibration;
a setting module configured to set the detection sensitivity between a plurality of levels:
wherein the setting module sets, respectively, the levels for the detection sensitivity correspondingly with a plurality of states of the electronic apparatus; and
wherein the setting module sets, independently:
a first level correspondingly with a first state in which the electronic apparatus is power-supplied from the AC adaptor, and
a second level correspondingly with a second state in which the electronic apparatus is power-supplied from the battery.
2. The electronic apparatus according to claim 1 , wherein the setting module sets:
the first level into a first default level, and
the second level into a second default level higher than that of the first level.
3. An electronic apparatus configured to have power-supplied to it by an AC adaptor or a battery, the electronic apparatus comprising:
a body;
an acceleration sensor configured to detect an acceleration applied on the body;
a disk device built in the body and configured to store
data;
a disk protection module configured to:
detect a vibration based on whether a change in the acceleration detected by the acceleration sensor exceeds a threshold; and
execute a protection function to protect the disk device in accordance with a detected result of the vibration; and
a setting module configured to set the threshold between a plurality of values,
wherein the setting module sets, respectively, the values for the threshold correspondingly with a plurality of states of the electronic apparatus, and
wherein the setting module sets, independently:
a first value correspondingly with a first state in which the electronic apparatus is power-supplied from the AC adaptor, and
a second value correspondingly with a second state in which the electronic apparatus is power-supplied from the battery.
4. The electronic apparatus according to claim 3 , wherein the setting module sets:
the first value into a first default value, and
the second value into a second default value lower than that of the first value.
