Abstract: A wireless communication apparatus with built-in terminal hub for transmitting a wireless signal includes a PCB, built-in antenna module and input terminal hub. The built-in antenna module disposed on the PCB transmits the wireless signal and the input terminal hub coupled with the PCB connects the computer. It avoids bringing the surrounding electromagnetic interference (EMI) and disorder. Besides, the built-in antenna module makes the whole size smaller and easy to carry. The wireless communication apparatus further provides an extended output terminal hub for connecting other peripheral device.

Abstract: AN MP3 broadcasting device, which can be used via plugging in a cigarette-lighter socket inside a car, has a cigarette-lighter plug, a frequency modulation (FM) radio module, a transmission module, a playing module, a control module and a frequency-setting module. The cigarette-lighter plug is used to obtain a first electric power from the cigarette-lighter socket and convert the first electric power into a second electric power suitable for the MP3 broadcasting device. The transmission module is used to connect with an external electronic device capable of outputting music signals to obtain the music signals. The playing module is used to process and play the received music signals, and then transmits the playing music via the FM radio module. Therefore, a user can use a radio inside the car to listen to music transmitted by the MP3 broadcasting device.

Abstract: A slim USB male connector with anti-disorientation design is mated with a USB socket. The USB male connector is received in a space between a mating board and a bottom wall of the USB socket. The USB male connector comprises a circuit board and an insulative housing. A top surface of USB male connector is mounted with four contacts. A bottom surface of the USB male connector is mounted with a grounding plate. The insulative housing covers the circuit board and has a plurality of grooves therein, and a pair of guiding boards respectively protruding from two sides thereof. The pair of guiding boards are respectively inserted into side gaps between the mating board and two sides of the frame of the USB socket.

Abstract: A slim USB male connector with system grounding mates with a USB socket. The USB male connector is received in a space between a mating board and a bottom wall of a frame of the USB socket. The USB male connector has a circuit board formed with a plurality of circuits on top and bottom surfaces thereof. Four contacts are formed on the top surface of the circuit board and connected with the circuits thereon. A grounding plate is mounted on the bottom surface of the circuit board and connected with a grounding circuit on the circuit board. The grounding plate connects to the tongues of the USB socket to ground the system.

Abstract: A wireless mouse capable of generating and accumulating electrical energy. The wireless mouse includes: (a) a first rolling wheel, which longitudinally props up the rolling ball and detects the displacement of the wireless mouse along the X-axis; (b) a second rolling wheel, which transversely props up the rolling ball and detects the displacement of the wireless mouse projected along the Y-axis; (c) an auxiliary rolling wheel, wherein the auxiliary rolling wheel, the first rolling wheel, and the second rolling wheel together prop up the rolling ball to keep the rolling ball in a certain rolling position; (d) at least one power generating device for transforming the dynamic energy produced by revolutions of the first/second rolling wheel to electrical energy; (e) an power storage device for storing electrical energy; and (f) a RF transmitting module for transmitting a moving signal of the wireless mouse and control signals of the left and right buttons.
