    摘要： In an electrical storage apparatus including an electric storage device connected between a main power supply and a load, a first bypass FET and a bypass diode which are connected in series between the main power supply and the load are provided, and first and second main path FETs connected in series between the electric storage device and the load are provided. A controller judges that the first bypass FET suffers an open-circuit failure if the voltage (Va) of the load is equal to or smaller than the first threshold value Vth1 or if the voltage (Vc) at the connection point between the first bypass FET and the bypass diode is equal to or smaller than the second threshold value Vth2, when the first bypass FET is turned on and the first main path FET and the second main path FET are turned off.

    摘要： A power management unit for a battery-operated electronic device having a bus interface for the interconnection with another electronic device, the power management unit including an electric energy storage element coupled between a battery of the battery-operated electronic device and a voltage supply line of the bus interface, the electric energy storage element being operable to charge/discharge electric energy; a drive circuitry arranged to control a charge/discharge of the electric energy storage element. The drive circuitry is operable to cause an electric power supplied by the other electronic device through the voltage supply line to re-charge the battery; or, in case the other electronic device does not supply electric power, cause the battery supply electric power to the other electronic device through the voltage supply line. The power management unit is particularly adapted for battery-operated, mobile USB OTG devices.

    摘要： A Universal Power Supply (UPS) protects audio/visual (A/V) components from damage that may occur due to a sudden power loss by first, providing back up power via a battery, and then initiating the normal, that is powered, shut down of the protected component via an infrared control signal. The infrared control signal is learned from the A/V components remote control unit.
