Electronic apparatus and method of detecting shock given to the electronic apparatus
View Patent ↗An electronic apparatus is provided that comprises a shock detector for detecting a shock received by an electronic apparatus such as a portable telephone, a controller for comparing the value of the shock as detected by the shock detector with a reference value, and a memory element for storing an identifying signal generated when the value of a shock has exceeded the reference value and the value of shock. This enabling easy determination as to whether or not a breakdown has been caused by shock.
1. An electronic apparatus comprising:
a shock detector unit for use with a load unit including:
(a) a shock detector including:
a shock detecting element; and
a conversion circuit for converting a signal from said shock detecting element into an electric signal;
(b) a controller for comparing a value of a shock as detected by said shock detector with a reference value; and
(c) a memory element for storing an identifying signal that is generated when said value of the shock has exceeded said reference value and said value of the shock,
wherein said shock detector unit is separate from said load unit, and a strength of said shock detector unit is higher than that of said load unit.
2. The electronic apparatus of claim 1 further comprising:
an external connection terminal that is connected to said controller and that outputs said identifying signal and said value of said shock stored in said memory element.
3. The electronic apparatus of claim 1 further comprising:
an alarm that is connected to said controller and that outputs an alarm signal based on said identifying signal.
4. The electronic apparatus of claim 3 , wherein said alarm has a sound-generating member.
5. The electronic apparatus of claim 3 , wherein said alarm has a light-emitting member.
6. The electronic apparatus of claim 3 , wherein said alarm has a display.
7. The electronic apparatus of claim 1 , wherein
said memory element stores said identifying signal, said value of said shock, and the time and date said shock has occurred.
8. The electronic apparatus of claim 1 , wherein
said shock detector is provided at a high strength location inside a case of the electronic apparatus.
9. A method of detecting a shock, said method comprising the steps:
(A) providing a shock detector unit for use with a load unit, said shock detector unit including:
(a) a shock detector including:
a shock detecting element; and
a conversion circuit for converting a signal from said shock detecting element into an electric signal;
(b) a controller for comparing a value of the shock as detected by said shock detector with a reference value; and
(c) a memory element for storing an identifying signal that is generated when said value of the shock has exceeded said reference value and said value of the shock,
wherein said shock detector unit is separate from the load unit and a strength of said shock detector unit is higher than that of said load unit;
(B) detecting said value of the shock by means of said shock detector of said shock detector unit;
(C) comparing said value of the shock with said reference value using said controller; and
(D) generating said identifying signal when said value of the shock has exceeded said reference value.
10. The method of detecting a shock of claim 9 further comprising the step of:
storing in said memory element said value of said shock and time and date said shock has occurred.
11. The method of detecting a shock according to claim 9 , said method further comprising the steps of:
storing said identifying signal in a memory element; and outputting the stored information from said memory element.
12. The electronic apparatus of claim 2 , wherein
said memory element stores said identifying signal, said value of said shock, and the time and date said shock has occurred.
13. The electronic apparatus of claim 3 , wherein
said memory element stores said identifying signal, said value of said shock, and the time and date said shock has occurred.
14. The electronic apparatus of claim 4 , wherein
said memory element stores said identifying signal, said value of said shock, and the time and date said shock has occurred.
15. The electronic apparatus of claim 5 , wherein
said memory element stores said identifying signal, said value of said shock, and the time and date said shock has occurred.
16. The electronic apparatus of claim 6 , wherein
said memory element stores said identifying signal, said value of said shock, and the time and date said shock has occurred.
