Abstract: An input system includes a communication device and a first input device. The communication device includes a communication chip and a communication port. The first input device includes a signal port connectable with the communication port and a device connecting port connectable with a second input device. In an input method, the communication device transmits a first pairing signal to the first input device so as to acquire a first identification code and a connection information of the first input device, and then the communication device transmits a first inquiring signal containing the first identification code to the first input device so as to acquire a first input signal from the first input device. If a second pairing signal and a second inquiring signal are transmitted to the second input device, the communication device acquires a second input signal from the second input device.

Abstract: A wireless input system includes a first computer, a second computer, a first-mode wireless connection device, a first input device and a second input device. When the first-mode wireless connection between the first input device and the first-mode wireless connection device is established and the first-mode wireless connection between the second input device and the first-mode wireless connection device is established, the first input device and the second input device can be operated to control the first computer. When the second-mode wireless connection between the first input device and the second computer is established, the second input device can follow the first input device to perform a connection switching operation. Consequently, the second-mode wireless connection between the second input device and the second computer is established.

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 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. 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 the bottom part of the mouse casing. At least one of the first sensing module and the second sensing module is exposed outside the mouse casing through the switching module. Consequently, a moving resolution of the mouse device is adjustable according to the practical requirements. When both of the first sensing module and the second sensing module are enabled, the moving resolution is further increased.

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.

Abstract: A mouse device includes a mouse casing, a first sensing module, a second sensing module and a switching module. The mouse casing includes a casing opening. Both of the first sensing module and the second sensing module are disposed on the switching module. Moreover, a part of the first sensing module and a part of the second sensing module are selectively exposed outside the casing opening. When the first sensing module or the second sensing module exposed outside the casing opening is rotated by the user, a switching body of the switching module is correspondingly rotated relative to the mouse casing. 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.
