Abstract

A position detection system is provided as including (i) a sound wave apparatus in a predetermined designated area and (ii) a detection terminal. The sound wave apparatus transmits a sound wave on which position information including a position of its own is superimposed as a detection sound wave. The detection terminal receives the detection sound wave, acquires the position information superimposed on the received detection sound wave, and stores the acquired position information as information indicating the position of the designated area.

First claim

What is claimed is:

1. A position detection system comprising (i) a sound wave apparatus provided in a predetermined designated area and (ii) a detection terminal,
the sound wave apparatus comprising:
an apparatus controller configured to acquire position information including a position of the sound wave apparatus; and
an apparatus sound wave transmitter connected with the apparatus controller, the apparatus sound wave transmitter being configured to transmit a detection sound wave that is a sound wave on which the position information acquired by the apparatus controller is superimposed,
the detection terminal comprising:
a terminal sound wave receiver configured to receive the detection sound wave; and
a terminal controller connected with the terminal sound wave receiver, the terminal controller being configured
to acquire the position information superimposed on the detection sound wave received by the terminal sound wave receiver, and
to store, in a memory, the acquired position information as information indicating the position of the designated area.

2. The position detection system according to claim 1 ,
wherein the apparatus sound wave transmitter in the sound wave apparatus is configured to transmit the detection sound wave towards at least inside of the designated area,
the sound wave apparatus is further comprises
an apparatus sound wave receiver connected with the apparatus controller, the apparatus sound wave receiver being configured to receive a reflected wave of the detection sound wave, and
wherein the apparatus controller is further configured
to acquire an elapsed time from when the detection sound wave is transmitted by the apparatus sound wave transmitter to when the reflected wave is received by the apparatus sound wave receiver, and
to determine that the designated area is in an empty state in response to that the elapsed time is equal to or greater than a predetermined threshold value.

3. The position detection system according to claim 1 , wherein
the apparatus sound wave transmitter in the sound wave apparatus comprises a first apparatus transmitter and a second apparatus transmitter,
the first apparatus transmitter being configured to transmit the detection sound wave towards inside of the designated area,
the second apparatus transmitter being configured to transmit the detection sound wave towards outside of the designated area.

4. The position detection system according to claim 3 , wherein
the second apparatus transmitter is configured to transmit the detection sound wave within a predetermined angle range by moving a movable machine.

5. The position detection system according to claim 1 , wherein
the terminal controller is further configured to instruct a display to display an image representing the position information.

6. The position detection system according to claim 1 , wherein
the detection terminal is configured to be carried by a user who uses the detection terminal.

7. The position detection system according to claim 1 , wherein
each of the apparatus controller and the terminal controller is configured by using at least one processor,
an individual processor of the at least one processor being configured to include
(i) at least one hardware circuit, or
(ii) at least one central processing unit along with memory storing instructions, or
(iii) a combination of (a) the at least one hardware circuit and (b) the at least one central processing unit along with memory.

8. A sound wave apparatus provided in a predetermined designated area, comprising:
an apparatus controller configured to acquire position information including a position of the sound wave apparatus; and
an apparatus sound wave transmitter connected with the apparatus controller, the apparatus sound wave transmitter being configured to transmit a detection sound wave that is a sound wave, which the position information acquired by the apparatus controller is superimposed on, to be received by a detection terminal.

9. The sound wave apparatus according to claim 8 , wherein
the apparatus sound wave transmitter in the sound wave apparatus is configured to transmit the detection sound wave towards at least inside of the designated area,
the sound wave apparatus further comprising:
an apparatus sound wave receiver connected with the apparatus controller, the apparatus sound wave receiver being configured to receive a reflected wave of the detection sound wave,
wherein the apparatus controller is further configured
to acquire an elapsed time from when the detection sound wave is transmitted by the apparatus sound wave transmitter to when the reflected wave is received, by the apparatus sound wave receiver and
to determine that the designated area is in an empty state in response to that the elapsed time is equal to or greater than a predetermined threshold value.

10. A detection terminal comprising:
a terminal sound wave receiver configured to receive a detection sound wave transmitted from a sound wave apparatus provided in a predetermined designated area, the detection sound wave on which position information including a position of the sound wave apparatus is superimposed; and
a terminal controller connected with the terminal sound wave receiver, the terminal controller being configured
to acquire the position information superimposed on the detection sound wave received by the terminal sound wave receiver, and
to store the acquired position information in a memory as information indicating the position of the designated area.
