  • Patent number: 8294373
    Abstract: An illumination apparatus is provided. The apparatus includes a power supply unit, a switch unit, a bulb, a wireless unit, and a control unit. The power supply unit is for supplying power. The switch unit is for opening or closing a circuit between the power source unit and the bulb. The wireless unit is for receiving wireless signals from an external control device, and generating a first control signal when receiving the wireless signals. The control unit is for generating a close signal according to the first control signal. The switch unit closes the circuit between the power source unit and the bulb according to the close signal to enable the bulb to keep emitting light; and opens the circuit between the power source unit and the bulb if no receiving the close signal, thereby keeping the bulb extinguishing. A related control device for controlling the apparatus is also provided.

  • Patent number: 7916093
    Abstract: A multiband antenna includes a conductive sheet, a feeding point, and a grounding point. The conductive sheet defines a first slot, a second slot, a third slot, a fourth slot, a fifth slot, a sixth slot, and a seventh slot thereon. The second slot and the third slot extend from a same short side of the first slot and are parallel to each other. The fourth slot, the fifth slot, the sixth slot, and the seventh slot extend perpendicularly from a short side of the third slot away from the first slot in sequence. The feeding point is formed on the conductive sheet at a long side of the first slot away from the third slot. The grounding point is formed on the conductive sheet at a margin of the slots different from the location of the feeding point.
