Abstract

A sensing device includes a radio-wave based sensor module, and a control processor configured to transmit data sensed by the radio-wave based sensor module to a mobile terminal. A holder is configured to hold the mobile terminal and to comprise the radio-wave based sensor module.

First claim

What is claimed is:

1. A sensing device, comprising:
a radio-wave based sensor module comprising two or more radar sensors configured to
transmit sensing signals,
form a sensing area by overlapping the transmitted sensing signals, and
receive sensing signals reflected by objects within the sensing area; and

a control processor configured to transmit, to a mobile terminal, data related to the objects based on a change in amplitude, phase or frequency between the transmitted sensing signals and the received reflected sensing signals,
wherein the sensing device is configured to be attached with the mobile terminal.

2. The sensing device of claim 1 , further comprising:
a driver configured to drive a motor,
wherein the control processor is configured to receive a control signal from the mobile terminal to drive the motor, and control the driver based on the control signal.

3. The sensing device of claim 1 , further comprising:
a mover comprising a wheel or propeller configured to be operated by the driver,
wherein the control processor is configured to receive a control signal from the mobile terminal to drive the motor and to operate the mover.

4. The sensing device of claim 1 , wherein the control processor is configured to receive, from the mobile terminal, a control signal associated with an operation of the sensing device, and control the two or more radar sensors based on the received control signal.

5. The sensing device of claim 1 , wherein the radio-wave based sensor module senses a position and a motion of an object, or a position of the object and a distance from the object.

6. The sensing device of claim 1 , wherein a sensing signal, of the sensing signals, sent by, or transmitted from, the radio-wave based sensor module is an impulse signal that is generated using a delay characteristic of a digital logic gate, and comprises a frequency spectrum in which energy is distributed in a wide frequency band.

7. The sensing device of claim 1 , wherein the radio-wave based sensor module detects a distance between the radio-wave based sensor module and an obstacle based on a time difference between a transmission of a sensing signal and a reception of a reflected signal from the obstacle.

8. The sensing device of claim 1 , wherein, based on a reduction in an amount of energy of a reflected signal with respect to a proceeding distance between the radio-wave based sensor module and an obstacle, the radio-wave based sensor module calculates the distance between the radio-wave based sensor module and the obstacle as corresponding to the detected amount of energy.

9. The sensing device of claim 1 , further comprising:
a holder configured to hold the mobile terminal and to comprise the radio-wave based sensor module.

10. The sensing device of claim 9 , wherein the holder is configured to hold the mobile terminal with a display of the mobile terminal facing a user.

11. The sensing device of claim 1 , wherein
the radio-wave based sensor module is configured to detect objects within a sensing area based on a corresponding change in amplitudes of plural signals being reflected from the objects.

12. The sensing device of claim 11 , wherein
the radio-wave based sensor module is configured to detect a time used until a detecting or sensing of a change in an amplitude of a signal, of the plural signals, reflected from an object after a sensing signal is sent from the radio-wave based sensor module.

13. A sensing device, comprising:
a radio-wave based sensor module comprising two or more radar sensors configured to
transmit sensing signals,
form a sensing area by overlapping the transmitted sensing signals, and
receive sensing signals reflected by objects within the sensing area; and

a control processor configured to transmit, to a mobile terminal, data related to the objects based on a change in amplitude, phase or frequency between the transmitted sensing signals and the received reflected sensing signals; and
a holder configured to hold the mobile terminal and to comprise the radio-wave based sensor module.
