Abstract: An automatic vehicle positioning management system includes an on-vehicle apparatus and a portable device. The on-vehicle apparatus, installed on a vehicle, acquires a first location of the vehicle through wireless positioning. The first location is sent to the portable device which acquires a second location of the vehicle through GPS. When multiple vehicles form a fleet, each vehicle respectively sends its first and second locations to a server through its portable device. The second location of each vehicle is corrected by operations of point error analysis, image overlay and point error correction, so that the fleet can be managed more precisely.

Abstract: Provided are a user verifying bicycle control system and a user verification method thereof, including a sensing module and a control module installed on a bicycle. The sensing module obtains a torque signal and an angle signal from a crank sensing component, further obtains a speed signal from a speed sensing unit, and outputs the torque signal, the angle signal, and the speed signal to the control module; the control module assembles the torque signal, the angle signal, and the speed signal into a signal sequence as a key to verify a user identity for the bicycle.

Abstract: A connector of a process field bus decentralized peripherals has a circuit board, two communicating cables each having two core wires and a shielding net layer, the two core wires coated by the shielding net layer, ends of the two core wires electrically connected to the circuit board, an inner shell mounted on the ends of the core wires by injection molding, a shielding layer covering the inner shell and the circuit board, the shielding layer electrically connected to the shielding net layers, and an outer shell mounted on the shielding layer by injection molding. Since the inner shell and the outer shell are formed by injection molding, the circuit board is tightly fixed in the connector. Further, the shielding layer is mounted between the inner shell and the outer shell to protect the circuit board from electromagnetic interference. Therefore, quality of the connector may be improved.

Abstract: Provided is a portable docking device. The portable docking device may convert an USB Type-C port to another type of port. The portable docking device can further receive electric power from a mobile device connected with the portable docking device, and the pico-projecting unit can receive the electric power to project an enlarged screen synchronous to a screen displayed on the mobile device. Therefore, the screen displayed on the mobile device can be enlarged, and viewers can watch the enlarged screen without the viewers' sight being blocked. Further, the user of the portable docking device does not need to bring a power adaptor, and convenience and portability of the portable docking device can be improved.

Abstract: A wireless barcode scanning system includes a wireless barcode scanning apparatus and an electronic apparatus, and a Bluetooth connection is established between the wireless barcode scanning apparatus and the electronic apparatus. The wireless barcode scanning apparatus reads a barcode to acquire barcode information of the barcode and the barcode information is transmitted to the electronic apparatus to be stored and/or displayed by the Bluetooth connection. Therefore, the wireless barcode scanning apparatus may be widely applied to the wireless transmission of scanned barcode data because of quick-speed induction and connection and high-volume data transmission.

Abstract: A flexible antenna includes a shell, an antenna, a flexible line, and a hollow unit. The flexible line is attached alongside the antenna and both the flexible line and the antenna are mounted in the shell. The hollow unit is connected with the shell, and is penetrated by the antenna. The flexible line has ductility and rigidity. The flexible line can be bent in any direction with the antenna because of the ductility of the flexible line. After the flexible line is bent, the flexible line can be fixed firmly because of the rigidity of the flexible line. A user can adjust a position of the antenna such that the antenna can receive wireless signals of good communication quality.

Abstract: A transmission apparatus for cellulous phone comprises a first connector, a conversion module and a second connector. The first connector is connected to a USB port of a computer and receives a charging signal and a data signal. The conversion module is connected to the first connector and converts the data signal and the charging signal from the first connector into signal accessible to the cellulous phone. The second connector is connected to the conversion module and transmits the serial data and the charging voltage to the cellulous phone connected to the second connector. The transmission apparatus can facilitate the cellulous phone and the computer to simultaneously perform charging battery, accessing wireless network and interchanging data operations.
