Abstract: A wireless input device includes an information receiving terminal and an information outputting terminal. The information receiving terminal generates a first-portion key. The information outputting terminal receives the first-portion key and generating a second-portion key. An original information is converted into an encrypted information by the information outputting terminal according to the first-portion key, the second-portion key and an encryption algorithm. The encrypted information and the second-portion key are transmitted from the information outputting terminal to the information receiving terminal. The encrypted information is restored to the original information by the information receiving terminal according to the first-portion key, the second-portion key and an encryption algorithm.

Abstract: A mouse device includes a mouse casing, a circuit board, a first sensing module, a second sensing module and a switching module. The circuit board is disposed within the mouse casing. Both of the first sensing module and the second sensing module are disposed on the circuit board and partially exposed outside the mouse casing. The switching module is partially exposed outside a base of the mouse casing. The first sensing module or the second sensing module is exposed outside the base under control of the switching module. Consequently, a moving resolution of the mouse device is adjustable according to the practical requirements. The switching module has a simple mechanism for changing the moving resolution of the mouse device in a simple manner.

Abstract: A wireless pairing system includes a signal receiver, a signal transmitter and a host device. The signal receiver includes a first wired connection port and a first wireless connection port. The signal transmitter includes a second wired connection port and a second wireless connection port. The host device is connected with the first wired connection port of the signal receiver and the second wired connection port of the signal transmitter. After a wired connection between the signal receiver and the host device and a wired connection between the signal transmitter and the host device are established, the signal receiver and the signal transmitter are paired with each other through the host device. Consequently, a wireless communication between the first wireless connection port and the second wireless connection port is enabled.

Abstract: A dynamic data transmission format adjustment method is provided. Firstly, a peripheral device raw input data is acquired from a device main body of a wireless peripheral device. Then, the peripheral device raw input data is converted into a variable-bit-length peripheral device transmission data according to a dynamic data transmission format conversion rule. Then, a network transmission packet containing the variable-bit-length peripheral device transmission data is generated, and the network transmission packet is transmitted to a wireless receiver of the wireless peripheral device. Then, the variable-bit-length peripheral device transmission data in the network transmission packet is converted and restored into a fixed-bit-length peripheral device transmission data according to the dynamic data transmission format conversion rule. Then, the fixed-bit-length peripheral device transmission data is transmitted from the wireless receiver to a computer host.

Abstract: A wireless mouse includes a mouse body and a wireless receiver. The wireless receiver is connected with a computer host. When the mouse body is operated by a user, an original information is generated. The original information is encrypted and converted into an encryption information by the mouse body. The wireless receiver receives the encryption information from the mouse body. After the encryption information is received by the wireless receiver, the encryption information is decrypted by the wireless receiver. Consequently, the encryption information is restored into the original information. After the computer host receives the original information through the wireless receiver, the computer host performs a corresponding operation.

Abstract: A keyboard device includes plural keys, a control unit and a membrane switch circuit member. The membrane switch circuit member includes a first upper key switch and a first lower key switch. When the first upper key switch is triggered by the first key, a first key code corresponding to the first key is generated by the first upper key switch. When the first lower key switch is triggered by the first key, a second key code corresponding to the first key is generated by the first lower key switch. The control unit is connected with the membrane switch circuit member. If both of the first key code and the second key code are received by the control unit, a key signal is outputted. If either the first key code or the second key code is received by the control unit, the key signal is not outputted.

Abstract: A Bluetooth pairing system includes an external device and a host device. The external device includes a Bluetooth module, a first transmission interface and a USB controller. When the external device is connected with the host device, a standard handshaking message complying with a USB communication protocol is issued from the processor to the external device. After the standard handshaking message is received by the USB controller of the external device, a device descriptor of the external device is transmitted from the USB controller to the host device. The device descriptor contains a vendor identification code, a product identification code, a product string and a product type of the external device and a target communication address of the Bluetooth module. The host device analyzes the device descriptor to acquire the target communication address of the Bluetooth module.
