Abstract

A wireless mouse having a receptacle for the storage of the wireless receiver is provided. The wireless mouse has a power saving device configured such that it would be triggered to switch the wireless mouse into a power saving mode when the wireless receiver is stored in the receptacle. In the power saving mode, only a small amount of electricity is drawn to maintain the memory of the earlier configured and established identification code and the communication link. When the wireless receiver is removed from the receptacle, the power saving device is triggered to switch the wireless mouse back to a normal operation mode and the memorized identification code and communication link are used automatically to communication with the wireless receiver directly and immediately.

Claims

1. A wireless mouse powered by an internal power source for a computing device operating along with a wireless receiver detachably installed on said computing device by transmitting RF signals to said wireless receiver over an identification code and a communication link configured and established between said wireless mouse and said wireless receiver, said wireless mouse characterized in that:

said wireless mouse has a receptacle for the storage of said wireless receiver;

said wireless mouse has a spring device inside said wireless mouse and an eject button on said wireless mouse configured such that, when said eject button is engaged, said wireless receiver stored inside said receptacle is expelled out of said receptacle by said spring device;

said wireless mouse operates in a normal operation mode when an operating voltage provided by said internal power source is around a pre-determined normal operating voltage;

said wireless mouse enters a power saving mode from said normal operation mode when said operating voltage provided by said internal power source drops below a pre-determined threshold, said power saving mode conserves the energy of said internal power source by drawing only the required power for memorizing said identification code and said communication link;

said wireless mouse resumes said normal operation mode when said operating voltage is restored around said normal operating voltage and said memorized identification code and communication link are used directly for communicating with said wireless receiver; and

said wireless mouse has a power saving device inside said wireless mouse configured such that the storage of said wireless receiver into said receptacle triggers said power saving device to switch said wireless mouse to operate in said power saving mode, and the removal of said wireless receiver from said receptacle triggers said power saving device to switch said wireless mouse to operate in said normal operation mode.

2. The wireless mouse according to claim 1, wherein said wireless mouse having an USB mini 5-pin connector for connecting to an external power source to charge said internal power source.
