Abstract:
The present invention discloses a surge protection circuit for a line driver. The surge protection circuit includes a transistor, including a first terminal coupled to a positive output pad of the line driver and a second terminal coupled to a negative output pad of the line driver, an inverter, including an output terminal coupled to a third terminal of the transistor, and a first RC circuit, including a resistor having a terminal coupled to an input terminal of the inverter and another terminal coupled to a power supply, and a capacitor having a terminal coupled to the input terminal of the inverter and another terminal coupled to a ground. A first RC time constant of the first RC circuit is substantially equal to or greater than a period of a differential mode surge signal.
Abstract:
A generating system includes a first generating device (1) and a second generating device (2). The first generating device includes a housing (11), a solar cell panel (12), a storage unit (13), a heat conduction layer (16), a heating chamber (14) and a plurality of water pipes (15). The second generating device includes an impeller (21), a propeller shaft (22) and a generator (23). Thus, the first generating device can receive the solar energy to produce an electric power, and the second generating device is driven by the wind power and the water power to generate an electrical energy so that the generating system can use the natural resources to produce an electrical energy at the day and the night so as to enhance the generating efficiency of the generating system.
Abstract:
In an electric appliance system, an electric appliance for performing designated functions and first and second remote controllers are included. The first remote controller is optionally triggered for controlling a first group of the designated functions, and the second remote controller is optionally triggered for controlling a second group of the designated functions. The second group includes at least one designated function included in the first group and at least one designated function excluded from the first group.
