| 20110195599 | FLAT RESTORABLE CABLE - A flat restorable cable has a cable body and two connectors. The cable body is wound to have a spirally wound form. The cable body is extended by pulling two ends of the cable, and restores back to the original spirally wound form once either end of the cable is released. The two connectors are securely mounted to respective ends of the cable body and used to respectively connect with two external compatible interfaces. As a result of less part required, compact size and thin thickness, the flat restorable cable addresses an inexpensive and portable solution to connect two electronic devices over a short distance. | 08-11-2011 |
| 20110095727 | POWER-SAVING LINE INTERACTIVE UNINTERRUPTIBLE POWER SYSTEM - A power-saving line interactive UPS has a power switch set, a low-frequency transformer, a full-bridge circuit, a main controller, a charge and discharge mode controller, a rechargeable battery and a high-frequency charging circuit. The high-frequency circuit is connected between an AC power input terminal and the rechargeable battery to convert the AC power into a DC power and charge the rechargeable battery. Therefore, when the AC power is normally supplied and the power capacity of the rechargeable battery is not full, the high-frequency charging circuit is activated to charge the rechargeable battery without charging the rechargeable battery through the low-frequency transformer and the full-bridge switching circuit, thereby effectively reducing overall power consumption. | 04-28-2011 |
| 20100237701 | Controlling method of a battery mode of a uninterruptible power supply for an active power factor corrected load - A controlling method of a battery mode of a UPS for an active PFC power supply has following acts of monitoring the AC power source and determining whether the AC power source is terminated or not; wherein if a determining result is positive go to next act; and switching to the battery mode and outputting a square wave power source. The square wave power source has a period, and each half of the period is alternately constituted by at least two ON times and at least two OFF times, and each of the at least two OFF times is equal or smaller than a hold-up time of the active PFC load. Therefore, the voltage of the bulk capacitor of the active PFC power supply at discharge condition is not lower than the low threshold voltage, since the OFF time of the square wave signal will be kept to be equal or less than the hold-up time. | 09-23-2010 |
| 20100163279 | Wire guide for electronic device - A wire guide for an electronic device has a base being mounted in the electronic device and a protecting tube being pivotally mounted in the base. Wires of the electronic device are mounted through the protecting tube so the wires pivot smoothly to connect the electronic device conveniently to a power supply. Therefore, The wires do not have to be bent or forced so the electronic device is more convenient to use, and safer since the wires and protective tube are not snapped easily. | 07-01-2010 |
| 20100064148 | Universal USB power supply - A universal series bus (USB) power supply has a DC power source, a USB power interface and a voltage modulation module. The USB power interface is for connecting to an electronic device that stores a default D+ voltage and a default D− voltage. The voltage modulation module connects to and outputs signals to the D+ and D− terminals of the USB power interface. If voltage levels of the output signals are not respectively identical to the default D+ and D− voltages, the voltage modulation module changes the voltage levels of the signals output to the D+ and D− terminals of the USB power interface until the voltage levels of the output signals are respectively identical to the default D+ and D− voltages. Therefore, the USB power supply may be applied to any kind of electronic device that is charged over a USB interface. | 03-11-2010 |
| 20090059636 | POWER ADAPTER HAVING AN ELECTRICITY STORING CAPABILITY - A power adapter has a body, a pair of blades, a DC output terminal, an AC to DC circuit, a node and a storage unit. The blades are mounted in and protrude from the body to connect to an AC power source to obtain AC power. The DC output terminal is mounted on the body to connect to a load. The AC to DC circuit is mounted in the body, converts the AC power into DC power and has an input terminal and an output terminal. The node is defined between the DC output terminal and the AC to DC circuit. The storage unit is connected to the node to store the DC power output from the AC to DC circuit and provide a stored DC output to the DC output terminal. | 03-05-2009 |
