Consequently, the optical device can function preferably also as a wavelength selective optical switch available in a WDM transmission system.

    摘要: A rechargeable battery protection integrated circuit that protects a rechargeable battery, by turning off a switching circuit inserted in series in a current path between a negative electrode of the rechargeable battery and a negative terminal that is coupled to ground of a load or a charger, includes a power source terminal that electrically connects to a positive electrode of the rechargeable battery, a ground terminal that electrically connects to the negative electrode of the rechargeable battery, a monitor terminal that electrically connects to the negative terminal via a resistor, to monitor a potential of the negative terminal, and a clamp circuit. The clamp circuit monitors a voltage of the power source terminal and a voltage of the monitor terminal, and limits the voltage of the monitor terminal to a voltage lower than or equal to the voltage of the power source terminal.

    摘要: A method for controlling power in a computer system having a network device and a wakeup function is disclosed. A determination is made whether or not the network device is in an associated state at the time when the computer system moves into a power saving mode. In response to a determination that the network device is not in the associated state, power supply is turned off from a power source to the network device. In response to a determination that the network device is in the associated state, power supply is continually provided from the power source to the network device.
