A preferred embodiment of the present invention will be described with reference to the accompanying drawings of Fig. 1 through Fig. 4.
Fig. 1 and Fig. 2 are drawings of automatic switching off device for a mobile phone according to the present invention. The automatic switching off device for a mobile phone of the present invention comprises: a transmission device 10 which comprises a switching off signal output unit 12 generating a switching control signal to turn off a power switch 7 of a mobile phone 1 and a transmission unit 11 which wirelessly transmits the switching control signal transmitted from the switching off signal output unit 12 as a signal with low electric field intensity in the low frequency band, and is installed in an appropriate location 13 of a place where instruments demanding high precision are located such as an intensive care unit or a research lab; a receiving device 8 which receives the low frequency band switching control signal transmitted from the transmission device 10 through the antenna ofthe mobile phone; and a switching control device 9 which automatically turns off a power switch by the switching control signal received by the receiving device 8 and cuts off battery power supply to an internal circuit, wherein the mobile phone 1 comprises a transmitter- receiver device 2 which transmits and receives data through an antenna, a control device 3 which controls each component for wireless communication, a key unit 4 to input phone numbers and various control commands, a handset device 5 for conversation, and a power switch 7 which makes switching operation to selectively supply battery 6 power to each component.
The operation ofthe present invention can be explained as follows. First of all, a user inputs other person's phone number by operating the key unit 4, and a dial tone corresponding to the phone number inputted by the key unit 4 is generated by the control device 3 and is transmitted to a base station through the handset device 5, resulting in connection to other person.
Then, conversation between said two parties are made by transmitting the voice of other person to the user through the handset device 5, and also by delivering the voice ofthe user to the other person through the handset device 5. A separate transmission device 10 is installed in an appropriate location 13 of a place where instruments demanding high precision are located such as an intensive care unit or a research lab.
The transmission device 10 comprises the transmission unit 11 and the switching off signal output unit 12. The switching off signal output unit 12 generates a switching control signal to turn off the power switch 7 of the mobile phone 1 and the transmission unit 11 wirelessly transmits the switching control signal as a signal with low electric field intensity in the low frequency band.
The transmission device 10 may be installed on the top, side or any place of the appropriate location 13, but the switching control signal transmitted by the transmission device 10 is maintained at low electric field intensity in the low frequency band, so that it does not exert bad influence on instruments demanding high precision installed in intensive care unit or a research lab.
Accordingly, when a user with the mobile phone 1 enters the appropriate location 13, the switching control signal transmitted by the transmission device 10 is delivered to the receiving device 8 through the antenna ofthe mobile phone 1, and the receiving device 8 delivers the inputted switching control signal to the switching control device 9.
The switching control device 9 automatically turns off the power switch 7 of the mobile phone 1 according to the inputted switching control signal which results in automatically turning off a mobile phone when a user's mobile phone enters a medical clinic or a research lab.
Therefore, when a user with the mobile phone 1 enters a medical clinic or a research lab, the mobile phone 1 is automatically turned off by the switching control signal transmitted by the transmission device 10 installed in the appropriate location 13 and any malfunctioning of high precision device installed in the medical clinic or a research lab due to high frequency electric wave from the mobile phone is prevented.
Fig. 3 and Fig. 4 are drawings of an automatic switching off device for a mobile phone according to another example of the present invention. The automatic switching off device for a mobile phone 1 comprises: multiple base stations which are installed in various places and connect a mobile phone to a switching station 21 by exchanging communication signals with the mobile phone 1 while maintaining its own field of operation; a switching station 21 which connects a mobile phone user to other user through public switched telephone network (PSTN) according to dial information of the mobile phone 1 inputted to the base station 20; and a switching off signal transmission device 30 which stores position information of a restricted area B such as an intensive care unit or a research lab where an instrument which demands high precision and is subject to malfunction by mobile phone frequency is installed, and comprises a comparison unit 32 which determines if the mobile phone 1 intrudes the restricted area B by the position information of the mobile phone received from the base station 20, and an switching off signal transmission unit 31 which transmits a switching control signal through the base station to automatically turn off a power switch 7 of the mobile phone 1 when the comparison unit 32 decides that the mobile phone 1 intrudes the restricted area B, wherein the mobile phone 1 comprises a transmitter-receiver device 2 which transmits and receives data through an antenna, a control device 3 which controls each component for wireless communication, a key unit 4 to input phone numbers and various control commands, a handset device 5 for conversation, and a power switch 7 which makes switching operation to selectively supply battery 6 power to each component.
The operation ofthe present invention can be explained as follows. The example illustrates that three base stations 20a - 20c maintain their own field of operation, and there is the restricted area B inside the second base station 20b as shown in Fig. 4.
When a user moves with the mobile phone 1, the mobile phone 1 notifies the position ofthe user and current standby state to the base station 20b by communicating with the base station 20b every designated period. The base station 20b transmits the current position of the mobile phone 1 to the comparison unit 32 ofthe switching off signal transmission device 30 through the switching station 21, and the comparison unit 32 decides if the user intrudes the restricted area. If mobile phone 1 comes close the restricted area B, the comparison unit 32 decides that the mobile phone 1 enters the restricted area B such as a medical clinic or a research lab, and the switching off signal transmission unit 31 transmits a switching control signal to turn off the mobile phone 1 to the mobile phone 1 through the corresponding base station 20b according to the decision ofthe comparison unit 32. The switching control signal is received by the transmitter-receiver device 2 of the mobile phone 1 and is delivered to the control device 3. The control device automatically turns off the power switch 7 formed at the output terminal ofthe battery 6 according to the inputted switching control signal, and therefore automatically turns off the mobile phone 1 when the mobile phone enters the restricted area B. The switching control signal transmitted from the switching off signal transmission unit 31 is set to function identically to the internal switching control signal of the mobile phone 1 generated when a user presses a power off key installed in the key unit 4.
As illustrated above according to another example of the present invention, therefore, when a user with the mobile phone 1 enters a medical clinic or a research lab, the mobile phone 1 is automatically turned off by the switching control signal transmitted by the switching off signal transmission device 30 and any malfunctioning of high precision device installed in the medical clinic or a research lab due to high frequency electric wave from the mobile phone 1 is prevented. Furthermore, according to another example of the present invention, an extra device need not be installed inside a mobile phone 1, and the production cost can be greatly lowered.
