Abstract

A wireless system has a host and a wireless peripheral, such as a cell phone and a corresponding wireless handset. When the system is in use, if a wireless connection between the host and the peripheral is disconnected, the wireless peripheral is capable of alerting a user by sound, light or vibration alarm. In addition, the host is capable of generating sound, light or vibration to indicate its location when it is disconnected.

Claims

1. A wireless peripheral for a host comprising:

a wireless module for communicating wireless signals with the host;

an alarm module for generating an alarm signal while receiving a control signal; and

a decision module between the alarm module and the wireless module;

wherein when the wireless module and the host is disconnected, the decision module generates the control signal to the alarm module for generating the alarm signal.

2. The wireless peripheral of claim 1 wherein the wireless peripheral is a wireless headset, the format of the alarm signal being one of the following:

sound, light, vibration, or a combination of such.

3. The wireless peripheral of claim 1 wherein the host is capable of transmitting a voice signal to the wireless module, the wireless peripheral further connecting to an interface module for transforming the voice signal into an analog voice;

the interface module generating an alarm sound while the alarm module receives the control signal.

4. The wireless peripheral of claim 1 wherein the host is capable of transmitting confirmation signals at different times;

the decision module generating the control signal to the alarm module if the decision module has not received the confirmation signals for a predetermined time.

5. The wireless peripheral of claim 1 wherein the host is capable of transmitting confirmation signals at different times;

the decision module generating the control signal to the alarm module if a number of the confirmation signals received in the decision module is smaller than a predetermined number for a predetermined time.

6. The wireless peripheral of claim 1 wherein the host transmits confirmation signals by the following methods:

regularly sending, irregularly sending, or their combination.

7. The wireless peripheral of claim 1 wherein the host transmits confirmation signals only when no other signals are to be transmitted to the wireless peripheral.

8. The wireless peripheral of claim 1 wherein the host is capable of transmitting a service signal, the wireless peripheral further comprising an interface module for transferring the service signal received in the wireless module into sound, vibration, or image.

9. The wireless peripheral of claim 8 wherein the host transmits the confirmation signal only when not transmitting the service signal.

10. The wireless peripheral of claim 1 wherein the wireless module is capable of transmitting request signals at different times, the host transmitting a confirmation signals for responding to the request signals.

11. A wireless system comprising:

a wireless peripheral; and

a host comprising;

a wireless module for communicating wireless signals with the wireless peripheral;

an alarm module for generating an alarm signal while receiving a control signal; and

a decision module between the alarm module and the wireless module;

wherein when the wireless module and the host is disconnected, the decision module generates the control signal to the alarm module for generating the alarm signal.

12. The wireless peripheral of claim 11 wherein the host is capable of transmitting confirmation signals at different times;

the decision module generating the control signal to the alarm module if the decision module has not received the confirmation signals for a predetermined time.

13. The wireless peripheral of claim 11 wherein the host is capable of transmitting confirmation signals at different times;

the decision module generating the control signal to the alarm module if a number of the confirmation signals received in the decision module is smaller than a predetermined number for a predetermined time.

14. The wireless peripheral of claim 11 wherein the host transmits confirmation signals by the following methods:

regularly sending, irregularly sending, or their combination.

15. The wireless peripheral of claim 11 wherein the host transmits confirmation signals only when no other signals are to be transmitted to the wireless peripheral.

16. The wireless peripheral of claim 11 wherein the wireless module is capable of transmitting a request signal at different times, the host transmitting a confirmation signal for responding to the request signal.

17. A method for a wireless system, the wireless system comprising a host and a wireless peripheral, the host capable of communicating wireless signals with the wireless peripheral;

the method comprising;

communicating wireless signals between the host and the wireless peripheral; and

when the wireless communication between the host and the wireless peripheral is disconnected, generating an alarm signal with the wireless peripheral.

18. The method of claim 17 further comprising:

transmitting confirmation signals at different times with the host; and

determining that the wireless communication between the host and the wireless peripheral is disconnected if the confirmation signals are not received in a predetermined time.

19. The method of claim 17 further comprising:

transmitting confirmation signals at different times with the host; and

determining that the wireless communication between the host and the wireless peripheral is disconnected if a number of the received confirmation signals is smaller than a predetermined number over a predetermined time.

20. The method of claim 17 further comprising:

transmitting request signals at different times with the wireless peripheral; and

transmitting confirmation signals for responding to the request signal with the host.
