20110037655 | Dielectric-loaded and coupled planar antenna - A dielectric-loaded and coupled planar antenna includes a ground plane, a radiator, a ceramic substrate and at least one ground coupling electrode. The radiator is formed by extending one side of the ground plane, and a feeding point is formed between the radiator and the ground plane. The radiator extends at least one end portion on the ceramic substrate. The ground coupling electrode is formed on the ceramic substrate by extending the other side of the ground plane. The ground coupling electrode formed on the ceramic substrate and the end portion of the radiator formed on the ceramic substrate are coupled with each other to form a coupling electrode. The present invention can adjust the coupling amount loaded by the ceramic substrate so as to be operated in a desired frequency range. The present invention can be operated in a single-frequency, dual-frequency or multi-frequency condition. | 02-17-2011 |

20110160928 | RANDOM CONTROLLED FUEL CELL POWER MODULE - The present invention discloses a random controlled fuel cell power module. The random controlled fuel cell power module includes a power module system, a current detection unit, and a random control unit. The power module system is composed of at least two parallel-connected DC/DC converters, for providing the power for a load. The current detection unit detects a load current value of the load. The random control unit reads the load current value and randomly assigns a control mode to activate the DC/DC converters according to the load current value, so that the DC/DC converters can be equally used. Therefore, the failure rate of the DC/DC converters is reduced, the life of the power module system is relatively prolonged, and the stability of the power module system is simultaneously increased. | 06-30-2011 |
20120104989 | CHARGE-CONTROLLING SYSTEM AND METHOD THEREFOR - A charge-controlling system and a method therefor are applicable to a backup power system having a fuel-cell-based power supply and a battery. The charge-controlling system includes a bidirectional converter, a feedback circuit, a voltage controller, a PWM generator, a switch unit and an over-charging protection circuit. The feedback circuit generates a feedback signal corresponding to an output voltage of the bidirectional converter. The voltage controller generates a control voltage according to the feedback signal and a constant voltage, such that the PWM generator generates a PWM signal based on the control voltage. The over-charging protection circuit controls operation of the switch unit according to the feedback signal and a saturation voltage of the battery. When the switch unit electrically connects the bidirectional converter and the PWM generator, the bidirectional converter charges the battery with the power generated by the fuel-cell-based power supply according to the PWM signal. | 05-03-2012 |

20150042551 | Utilizing Gray Code to Reduce Power Consumption in Display System - A system and method are disclosed to utilize Gray code in order to reduce the power consumption of column drivers in a display system. Binary source data is received from a timing controller. A Gray code digitizer converts and encodes the binary source data into a binary portion of data and a Gray code data. The binary portion data and the Gray code data are transmitted through a shift register to a digital-to-analog converter. The shift register consumes less power processing the converted binary portion of data and Gray code data than the corresponding binary source data. The digital-to-analog converter decodes the Gray code and generates corresponding gamma voltage levels for display use. | 02-12-2015 |
