Abstract

Provided is a diagnosis apparatus. The diagnosis apparatus includes: an internal device inserted into an inside of a body and moving therein; and an external device located at an outside of the body and controlling the internal device, wherein the internal device includes: a first communication unit communicating with the external device; a power supply unit supplying power for driving of the internal device; and a first control unit controlling an operation of the internal device according to a control signal when the control signal is received from the external device, and the external device includes: a second communication unit communicating with the internal device; a location detection unit processing a signal received from the internal device to detect a location of the internal device; and a second control unit generating a control signal for controlling the internal device based on the location of the internal device.

Claims

1. An internal device inserted into an inside of a body and moving therein, the internal device comprising:

a communication unit communicating with an external device located at an outside of the body;

a power supply unit supplying power for driving of the internal device; and

a control unit controlling an operation of the internal device according to a control signal when the control signal is received from the external device.

2. The internal device of claim 1, wherein the communication unit transmits and receives a signal wirelessly by using an antenna or through the body by using an electrode.

3. The internal device of claim 1, further comprising a camera unit capturing an image of the inside of the body.

4. The internal device of claim 3, wherein the communication unit transmits, to the external device, image data obtained through a corresponding image-capturing operation whenever the camera unit captures an image.

5. The internal device of claim 3, wherein the camera unit starts capturing an image in response to an image-capturing initiation request from the external device and finishes capturing an image in response to an image-capturing stop request from the external device.

6. The internal device of claim 5, wherein the communication unit transmits image data obtained from an image-capturing start request time to an image-capturing stop request time to the controller in response to the image-capturing stop request.

7. The internal device of claim 1, wherein the control unit switches the internal device to an idle mode to reduce power consumption, when a power cutoff signal is received from the external device.

8. The internal device of claim 7, wherein the control unit switches the internal device to an operation mode to increase power consumption, when a power-supply connection signal is received from the external device.

9. The internal device of claim 3, wherein the control unit is configured to:

cut off power supply from the power supply unit to the camera unit when a power supply cutoff signal is received from the external device, and

enable the power supply unit to supply power to the camera unit when a power-supply connection signal is received from the external device.

10. An external device located at an outside of a body and controlling an internal device inserted into an inside of the body and moving therein, the external device comprising:

a communication unit communicating with the internal device;

a location detection unit processing a signal received from the internal device to detect a location of the internal device; and

a control unit generating a control signal for controlling the internal device based on the location of the internal device.

11. The external device of claim 10, wherein the communication unit comprises at least three receivers located at different points on the body and receiving a signal from the internal device.

12. The internal device of claim 11, wherein the location detection unit is configured to:

calculate a difference between times when each receiver receives a signal from the internal device, and

detect the location of the internal device based on a time difference between received signals.

13. The external device of claim 11, wherein the receivers are located on the same plane, and

the communication unit further comprises at least one secondary receiver located at another point on the body spaced apart from the same plane.

14. The external device of claim 13, wherein the receivers are located at any one of front and rear sides of a human body, and

the secondary receiver is located at another one of the front and rear sides.

15. The external device of claim 13, wherein the receivers are located at any one of front and rear sides of a human body, and

the secondary receiver is located on a lateral face of the human body.

16. A diagnosis apparatus comprising:

an internal device inserted into an inside of a body and moving therein; and

an external device located at an outside of the body and controlling the internal device,

wherein the internal device comprises;

a first communication unit communicating with the external device;

a power supply unit supplying power for driving of the internal device; and

a first control unit controlling an operation of the internal device according to a control signal when the control signal is received from the external device, and

the external device comprises;

a second communication unit communicating with the internal device;

a location detection unit processing a signal received from the internal device to detect a location of the internal device; and

a second control unit generating a control signal for controlling the internal device based on the location of the internal device.
