摘要:
A method for P2P signal synchronization and P2P wireless communication device and system using the same. The method includes the following steps. A first P2P wireless communication device having an effective range acts as a master device. At least one second P2P wireless communication device located in the effective range is paired and connected with the first P2P wireless communication device. When the first P2P wireless communication device acts as the master device, the first P2P wireless communication device broadcasts a synchronization signal. After the at least one second P2P wireless communication device receives the synchronization signal, at least one second P2P wireless communication device is switched to the master device and broadcasts the synchronization signal.
摘要:

摘要:
An expandable keyboard device includes a keyboard, and a supporting assembly having interconnected first and second panels. The second panel is adapted to connect with an electronic device. The supporting assembly is movable relative to the keyboard between an unfolded state, where the first panel extends upwardly relative to the keyboard for supporting the electronic device above the keyboard, and a folded state, where the second panel along with the electronic device cover the keyboard. An electrical connector is disposed in the housing for electrical connection with the electronic device. A connecting unit interconnects the supporting assembly and the keyboard.
