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 includes the main body and the inertial roller module. The inertial roller module is installed in the main body. The inertial roller module includes a supporting bracket, a roller, a gear assembly and an encoding element. The roller is pivotally coupled to the supporting bracket. The gear assembly includes a first gear and a second gear. The first gear is connected with the roller. The first gear and the second gear are engaged with each other. The number of teeth in the first gear is larger than the number of teeth in the second gear. The encoding element is connected with the roller. Consequently, the time period of rotating the roller is increased.

Abstract: An air pressure sensing type mouse includes a housing, a circuit board, plural air pressure sensors and a processor. One of the plural air pressure sensors is a middle air pressure sensor. The processor stores a threshold value. When an ambient airflow inputs into the housing of the mouse, the plural pressure sensors sense the ambient airflow and generates plural sensed values. If the plural sensed values are all smaller than the threshold value, the middle air pressure sensor generates a pressing signal. If the plural sensed values are all higher than the threshold value, the middle air pressure sensor generates a vertical displacement signal.

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.

Abstract: A testing system uses different operating systems to test electronic products. The testing system includes a master computer, a slave computer and a relay. A first operating system is installed in the master computer. A second operating system is installed in the slave computer. The master computer and the slave computer are connected with each other through RS-232 ports. The relay is connected with the master computer, the slave computer and an under-test product. By changing the voltage level state of specified pins of the RS-232 ports, the master computer notifies the slave computer to test the under-test product. Moreover, by controlling the relay, the connection between the master computer and the under-test product is switched to the connection between the slave computer and the under-test product. Consequently, the under-test product is tested by the slave computer.

Abstract: A car seat with a warning function includes a seat body having a seat cushion, plural adjusting posts, a wireless transmission module, a control unit and a warning element. The wireless transmission module is in wireless communication with an electronic device. When the adjusting posts are pushed by the seat cushion, the lengths of the adjusting posts are changed. If the control unit receives a body curve data from the electronic device and judges that the body curve data complies with a predetermined body data, the control unit changes the lengths of the adjusting posts according to the body curve information. Consequently, the shape of the seat cushion fits the body shape of the user. If the control unit judges that the body curve data does not comply with the predetermined body data, the control unit controls the warning element to output a warning signal.

Abstract: A keyboard device includes a key structure, a switch circuit board, a base plate, a soft covering element and a buffering pad. The key structure includes a keycap and a stabilizer bar. The stabilizer bar is connected with the keycap and the soft covering element. The soft covering element is disposed on the base plate. An accommodation space is defined by the soft covering element and the base plate collaboratively. The stabilizer bar is inserted into the accommodation space, so that the stabilizer bar is connected with the base plate. The buffering pad is disposed on the base plate and partially received within the accommodation space. The stabilizer bar and the base plate are made of metallic material. Since the stabilizer bar and the base plate are separated by the soft covering element and the buffering pad, the keyboard device is capable of reducing noise.
