Electronic apparatus
View Patent ↗According to one embodiment, an electronic apparatus includes a first unit and circuitry. The first unit includes first and second sensors and a wireless device. The first sensor detects approach of an object. The second sensor detects whether the first unit is open or closed. The circuitry reduces transmission power of the wireless device when the first sensor detects approach of the object, and not to reduce transmission power when the second sensor detects a change from an open state to a closed state and the first sensor detects approach of the object.
1. An electronic apparatus comprising:
a first unit configured to be open and closed with respect to a second unit, the first unit comprising a first sensor, a second sensor, and a wireless communication device, wherein the first sensor is configured to detect approach of an object, and the second sensor is configured to detect whether the first unit is open or closed; and
circuitry configured to reduce transmission power of the wireless communication device when the first sensor detects approach of the object, and not to reduce transmission power of the wireless communication device when the second sensor detects a change from an open state to a closed state and the first sensor detects approach of the object.
2. The electronic apparatus of claim 1 , wherein:
the circuitry is configured to reset the first sensor when the first sensor detects approach of the object while the second sensor detects a change from an open state to a closed state; and
a detection result of the first sensor indicates nonproximity when the first sensor is reset.
3. The electronic apparatus of claim 1 , wherein:
the circuitry is configured to reset the first sensor when the first sensor detects that the object has changed from not being approaching to being approaching while the second sensor detects a change from an open state to a closed state; and
a detection result of the first sensor indicates nonproximity sensor is reset.
4. The electronic apparatus of claim 1 , wherein:
the circuitry is configured to turn off and then turn on a power supply of the first sensor when the first sensor detects approach of the object while the second sensor detects a change from an open state to a closed state; and
a detection result of the first sensor indicates nonproximity when the power supply of first sensor is turned on.
5. The electronic apparatus of claim 1 , wherein:
the circuitry is configured to turn off and then turn on a power supply of the first sensor when the first sensor detects that the object has changed from not being approaching to being approaching while the second sensor detects a change from an open state to a closed state; and
a detection result of the first sensor indicates nonproximity when the power supply of the first sensor is turned on.
6. The electronic apparatus of claim 1 , wherein:
the second unit comprises a keyboard;
the first unit comprises a display mounted on the keyboard, the display being configured to be open and closed; and
the first sensor comprises a capacitive proximity sensor configured to detect approach of a human body or the keyboard.
7. The electronic apparatus of claim 6 , wherein:
the keyboard comprises a keyboard dock;
the display comprises a tablet mounted on the keyboard dock to be attachable and detachable, the tablet being configured to be open and closed with respect to the keyboard dock.
8. A method electronic apparatus,
the electronic apparatus comprising:
a first unit configured to be open and closed with respect to a second unit, the first unit comprising a first sensor, a second sensor, and a wireless communication device, wherein the first sensor is configured to detect approach of an object, and the second sensor is configured to detect whether the first unit is open or closed,
the method comprising:
reducing transmission power of the wireless communication device when the first sensor detects approach of the object; and
not reducing transmission power of the wireless communication device when the second sensor detects a change from an open state to a closed state and the first sensor detects approach of the object.
9. The method of claim 8 , further comprising:
resetting the first sensor when the first sensor detects approach of the object while the second sensor detects a change from an open state to a closed state,
wherein a detection result of the first sensor indicates nonproximity when the first sensor is reset.
10. The method of claim 8 , further comprising:
resetting the first sensor when the first sensor detects that the object has changed from not being approaching to being approaching while the second sensor detects a change from an open state to a closed state,
wherein a detection result of the first sensor indicates nonproximity when the first sensor is reset.
11. The method of claim 8 , further comprising:
turning off and then turn on a power supply of the first sensor when the first sensor detects approach of the object while the second sensor detects a change from an open state to a closed state,
wherein a detection result of the first sensor indicates nonproximity when the power supply of the first sensor is turned on.
12. The method of claim 8 , further comprising:
turning off and then turn on a power supply of the first sensor when the first sensor detects that the object has changed from not being approaching to being approaching while the second sensor detects a change from an open state to a closed state,
wherein a detection result of the first sensor indicates nonproximity when the power supply of the first sensor is turned on.
13. The method of claim 8 , wherein:
the second unit comprises a keyboard,
the first unit comprises a display mounted on the keyboard, the display being configured to be open and closed, and
the first sensor comprises a capacitive proximity sensor configured to detect approach of a human body or the keyboard.
14. The method of claim 13 , wherein:
the keyboard comprises a keyboard dock,
the display comprises a tablet mounted on the keyboard dock to be attachable and detachable, the tablet being configured to be open and closed with respect to the keyboard dock.
