  • Patent number: 9699872
    Abstract: A control system for wirelessly switching lamps over short distances includes a mobile device, a lamp control switch and a controlled lamp. A user holds the mobile device to approach or depart from the lamp control switch and continuously transmit a wireless signal according to a communication protocol. The lamp control switch receives the wireless signal according to the communication protocol and turns on or off a corresponding controlled lamp according to signal intensity of the wireless signal. The control system is operated when users travel among different environments. When users get close to the lamp control switch, the lamp control switch drives the controlled lamp to turn on or off, and when users depart from the lamp control switch, the lamp control switch automatically turns off the controlled lamp, thereby ensuring operational convenience, energy conservation and carbon reduction.

  • Publication number: 20160275468
    Abstract: An electricity consumption billing method includes steps of mounting a power detection switch, recording a first average amount of electricity consumption of an electric appliance in a first time duration, recording a second average amount of electricity consumption of the electric appliance in a second time duration, and calculating an incentive amount according to the first average amount of electricity consumption and the second average amount of electricity consumption. An electric power company records the first and second average amounts of electricity consumption of the electric appliance and calculates a one-time additional incentive amount. When customers improve power utilization efficiency, not only can the amount of the electric bill be saved, but also the electric power company further offers the incentive amount to encourage customers to improve power utilization efficiency and reduce consumption of electric energy.

  • Patent number: 9184580
    Abstract: An arrester includes a switch and a lightning detection breaker connected to the switch. The lightning detection breaker includes a metal conducting terminal electrically connected to an earth return, a DC power supply terminal, a ground terminal and an output terminal. When the power supply is under a lightning strike, a potential difference of both the DC power supply terminal and the ground terminal of the lightning detection breaker will go up to several thousands of volts. However, a voltage of the metal conducting terminal will not go up because the metal conducting terminal is electrically connected to the earth return. The switch will automatically become open circuit by the lightning detection breaker, and therefore an electronic device connected to the arrester is protected from damage done by the lightning.
