Abstract

A portable telephone is provided with a first memory 1, a second memory 2, a first CPU 3, a second CPU 4, an interface 5, an antenna 6, a battery 7, and a switch 8. When buildings are collapsed and the user of the portable telephone is left under rubble, a rescuer transmits an emergency signal toward the collapsed site by using a transmission unit. The emergency signal includes key information. The signal is received by the portable telephone and then sent to the first CPU 3 via the antenna 6 and the interface 5. The first CPU 3 compares the key information included in the received signal with key information stored in the first CPU 3. A rescue signal is transmitted via the antenna 6 and the interface 5 on condition that both pieces of key information match. The rescue signal is received by the rescue party and as such, the position of the portable telephone is determined.

Claims

1. A rescue system provided with a mobile, telephone apparatus and a robot, comprising:

a mobile telephone apparatus having a storage unit in which key information is stored;

a reception unit for receiving an emergency signal including key information;

a control unit for determining whether the key information stored in the storage unit and the key information included in the emergency signal match;

a transmission unit for transmitting a rescue signal, wherein when the key information stored in the storage unit and the key information included in the emergency signal match, the transmission unit transmits a rescue signal;

means to generate a sound wave together with the rescue signal when the key information stored in the storage unit and the key information stored in the emergency signal match; and

a robot for moving close to the mobile telephone apparatus while receiving the rescue signal transmitted from the mobile telephone apparatus,

wherein the robot performs the reception of the rescue signal and the reception of the sound wave; and

wherein the distance between the robot and the mobile telephone apparatus is determined based on a time lag between reception of the rescue signal and reception of the sound wave by the robot.

2. The rescue system according to claim 1, wherein the robot includes means for correcting the velocity of sound on the basis of environment parameters.
