Abstract

A device and method for a wireless mouse to detect the battery status of a host computer are proposed. A low-battery monitor mode of a battery is activated. Whether the battery has a low-battery status is determined. A notification message of the low-battery status is intercepted. The notification message is sent to a receiving unit of the wireless mouse by means of wireless transmission. The device has a battery module for providing power for the host computer, a battery capacity detection module electrically connected to the battery module for detecting its capacity, a transfer unit electrically connected to the battery capacity detection module for transferring the present battery status of the host computer, a receiving unit for receiving signals from the transfer unit, and a wireless mouse display unit electrically connected to the receiving unit for displaying the present battery capacity status of the host computer.

Claims

1. A method for a wireless mouse to detect a battery status of a host computer, the method comprising the steps of:

activating a low-battery monitor mode of a battery;

determining whether said battery has a low-battery status;

intercepting a notification message of said low-battery status; and

sending said notification message of said low-battery status to a receiving unit of said wireless mouse by means of wireless transmission.

2. The method for a wireless mouse to detect the battery status of a host computer as claimed in claim 1, wherein in said step of determining whether said battery has a low-battery status, if an answer is yes, a step of sending said notification message of said low-battery status to a host computer display unit is performed, and otherwise, the method returns to said step of activating a low-battery monitor mode of a battery.

3. The method for a wireless mouse to detect the battery status of a host computer as claimed in claim 2, wherein the display type can be a graphics or a voice alarm in said step of sending said notification message of said low-battery status to a host computer display unit.

4. The method for a wireless mouse to detect the battery status of a host computer as claimed in claim 1, wherein a firmware or a driver is used to intercept said notification message in said step of intercepting a notification message of said low-battery status.

5. The method for a wireless mouse to detect the battery status of a host computer as claimed in claim 1, further comprising a step of sending said notification message of the low-battery status to a transfer unit in said host computer after said step of intercepting a notification message of said low-battery status.

6. The method for a wireless mouse to detect the battery status of a host computer as claimed in claim 1, wherein the wireless transmission is accomplished by means of RF signal transmission.

7. The method for a wireless mouse to detect the battery status of a host computer as claimed in claim 1, wherein the wireless transmission is accomplished by means of bluetooth signal transmission.

8. The method for a wireless mouse to detect the battery status of a host computer as claimed in claim 1, further comprising a step of sending said received notification message of said low-battery status to a wireless mouse display unit after said step of sending said notification message of the low-battery status to a receiving unit of said wireless mouse by means of wireless transmission.

9. A device for a wireless mouse to detect the battery status of a host computer capable of transferring a present battery status of said host computer to a wireless mouse display unit by means of wireless transmission, said device comprising:

a battery module for providing the required power for said host computer;

a battery capacity detection module electrically connected to said battery module for detecting the capacity of said battery module;

a transfer unit electrically connected to said battery capacity detection module for transferring the present battery status of said host computer to said wireless mouse;

a receiving unit for receiving signals from said transfer unit by means of said wireless transmission; and

a wireless mouse display unit electrically connected to said receiving unit for displaying the present battery capacity status of said host computer.

10. The device for a wireless mouse to detect the battery status of a host computer as claimed in claim 9, further comprising a host computer display unit electrically connected to said battery capacity detection module for displaying the present battery capacity status of said host computer.

11. The device for a wireless mouse to detect the battery status of a host computer as claimed in claim 9, wherein said host computer display unit is a screen.

12. The device for a wireless mouse to detect the battery status of a host computer as claimed in claim 9, wherein said wireless mouse display unit comprises at least an LED.
