  • Patent number: 9414469
    Abstract: An integrated lamp with automatic emergency light and regular light is provided in the present invention. The integrated lamp with automatic emergency light and regular light is coupled to an AC power source, wherein the AC power source includes a first AC terminal and a second AC terminal. The integrated lamp is controlled by a lamp switch, where the lamp switch includes a first terminal and a second terminal, where an indication light circuit is coupled between the first terminal and the second terminal of the lamp switch. The integrated lamp includes an AC detector. The AC detector is coupled between the second terminal of the lamp switch and the second AC terminal.

  • Patent number: 9276633
    Abstract: A power line communication control system adapted for single-wire and method thereof are provided in the present invention. The power line communication control method adapted for single-wire includes: receiving a AC voltage from a AC power wire, wherein each period of the AC voltage includes a positive half cycle and a negative half cycle to form a sinusoidal AC signal; and adjusting the positive half cycle and the negative half cycle of the sinusoidal AC signal according to a digital data to be transmit to a load circuit. The step of adjusting the positive half cycle and the negative half cycle of the sinusoidal AC signal includes removing a first component of the positive half cycle of the sinusoidal AC signal and a second component of the negative half cycle of the sinusoidal AC signal to obtain a phase cutting signal. When the digital data is a first logic, the positive half cycle of the phase cutting signal is equal to the negative half cycle of the phase cutting signal.
