  • Patent number: 9112301
    Abstract: An electrical connector for a cable includes a PCB and a fixed element for holding the PCB. The PCB includes several first contacting fingers and second contacting fingers electrically connected to each other at different sides along a first direction. The first and second contacting fingers are respectively arranged along a second direction perpendicular to the first direction to be disposed in two rows. The second contacting fingers are connected to the cable. Wherein said PCB is longer than said fixed element so as to expose first contacting fingers at a front side of the fixed element along the first direction and form a mating port for a mating connector.

  • Patent number: 8115407
    Abstract: An address-free driving device and lighting fixture system are disclosed. The device is applied in controlling a lighting device, and includes a serial interface, a signal converter, a signal processor and a lighting driving unit. The signal converter converts an inputted signal from the serial interface into a digital signal. The signal processor then extracts a controlling data corresponding to the address-free driving device from the digital signal, and determines whether or not the inputted signal from the serial interface can be outputted to another address-free driving device. The lighting driving unit drives the lighting device to illuminate light based on the controlling data. Accordingly, when the lighting devices are electrically and serially connected, the address-free driving device then controls the lighting devices based on the order of series connection.

  • Patent number: 7564423
    Abstract: A printed dipole antenna used in an electronic device comprising a PCB comprising some through holes; a grounding element locating on one side of the PCB; a radiating element locating on common side of the PCB with the grounding element; a coaxial cable comprising a inner conductor connecting to the radiating element and a braiding layer connecting to the grounding element; and a short circuit element locating on another side of the PCB electrically connecting the radiating element and the grounding element by said through holes. When the printed dipole antenna encounter an intense electromagnetic field, the interferential signal transmitting from the intense electromagnetic field would arrive to the grounding element through the radiating element. The interferential signal cannot arrive to the system and is unable disturb the working of the printed dipole antenna.
