Abstract

An electronic apparatus attachable to a door and a method of determining door states. The electronic apparatus includes a sensor configured to measure an acceleration and an angular speed of the electronic apparatus, a processor configured to determine a state of the door by using the measured acceleration and angular speed, and a communicator configured to transmit the determined state of the door to an external apparatus.

First claim

What is claimed is:

1. An electronic apparatus attached on a door, the electronic apparatus comprising:
a sensor device configured to measure acceleration and angular speed of the electronic apparatus;
a processor configured to identify a type of the door, sense an arrangement between the door and a doorframe to which the door is fixed, by using at least one of the acceleration and the angular speed based on the type of the door, and identify a door state as to whether the door is one of opened and closed, according to the arrangement; and
a communicator configured to transmit the state of the door to an external apparatus,
wherein the processor senses the arrangement based on the angular speed if the type of the door is a pivotable door and senses the arrangement based on the acceleration if the type of the door is a sliding door.

2. The electronic apparatus of claim 1 , wherein the pivotable door is pivotable based on an axis of the doorframe.

3. The electronic apparatus of claim 1 , wherein the processor compensates for the angular speed using the acceleration and senses the arrangement based on a compensated angular speed.

4. The electronic apparatus of claim 1 , wherein the sliding door is movable back and forth in a straight line direction based on the doorframe.

5. The electronic apparatus of claim 1 , wherein the processor determines one of a knock and an external intrusion by using the acceleration in response to the state of the door being a closed state.

6. The electronic apparatus of claim 5 , wherein in response to the state of the door being determined as the one of the knock and the external intrusion, the processor controls the communicator to notify the external apparatus of the state of the door.

7. The electronic apparatus of claim 1 , wherein in response to one of the state of the door being changed and a state request being received from the external apparatus, the processor controls the communicator to transmit the state of the door to the external apparatus.

8. The electronic apparatus of claim 1 , wherein in response to changes in the acceleration and the angular speed measured for a predetermined time or more, being within a predetermined range, the processor changes an operation mode of the electronic apparatus into a standby mode.

9. The electronic apparatus of claim 8 , wherein in response to an acceleration change higher than or equal to a predetermined value, being sensed, the processor changes the operation mode of the electronic apparatus from the standby mode into the operation mode.

10. A method of determining a door state of an electronic apparatus attachable to a door, the method comprising:
measuring acceleration and angular speed of the electronic apparatus;
identifying a type of the door;
sensing an arrangement between a doorframe to which the door is fixed and the door, by using at least one of the acceleration and the angular speed based on the type of the door;
identifying the door state as to whether the door is one of opened and closed, according to the arrangement; and
transmitting the state of the door to an external apparatus,
wherein the sensing comprises sensing the arrangement based on the angular speed if the type of the door is a pivotable door and sensing the arrangement based on the acceleration if the type of the door is a sliding door.

11. The method of claim 10 , wherein the pivotable door is a pivotable based on an axis of the doorframe.

12. The method of claim 10 , wherein the sensing comprises compensating for the angular speed by using the acceleration and sensing the arrangement based on a compensated angular speed.

13. The method of claim 10 , wherein the sliding door is movable back and forth in a straight line direction based on the doorframe.

14. The method of claim 10 , further comprising:
in response to the state of the door being a closed state, determining one of a knock and an external intrusion by using the acceleration.

15. The method of claim 14 , further comprising:
in response to the state of the door being the one of the knock and the external intrusion, notifying the external apparatus of the state of the door.

16. The method of claim 10 , wherein the transmitting comprises, in response one of to the state of the door being changed and a state request being received from the external apparatus, transmitting the state of the door to the external apparatus.

17. The method of claim 10 , further comprising:
in response to changes in the acceleration and the angular speed measured for a predetermined time or more, being within a predetermined range, changing an operation mode of the electronic apparatus into a standby mode.

18. The method of claim 17 , further comprising:
in response to an acceleration change higher than or equal to a predetermined value, being sensed, changing the operation mode of the electronic apparatus from the standby mode into the operation mode.

19. A non-transitory computer readable recording medium storing a method of determining a door state of an electronic apparatus attachable to a door, the method comprising:
measuring acceleration and angular speed of the electronic apparatus;
identifying a type of the door;
sensing an arrangement between a doorframe to which the door is fixed and the door, by using at least one of the acceleration and the angular speed based on the type of the door;
identifying the door state as to whether the door one of is opened and closed, according to the arrangement; and
transmitting the state of the door to an external apparatus,
wherein the sensing comprises sensing the arrangement based on the angular speed if the type of the door is a pivotable door and sensing the arrangement based on the acceleration if the type of the door is a sliding door.
